Commercial real estate (CRE) refers to a broad range of properties, including office buildings,

hotels, retail storefronts, restaurants, hospitals, stadiums, schools, and apartments. The market for
Economics
CRE financing is over $3 trillion. In some ways, CRE is financed similarly to a house. A

borrower takes out a mortgage from a lender to purchase a property, and the property acts as
security for the loan. That lender can keep the mortgage on its books or sell it to other financial

firms, which may package the mortgage with other CRE mortgages into an instrument known as
a commercial mortgage-backed security (CMBS). CMBS are tradable securities whose interest payments to investors flow
from the mortgage payments made by CRE borrowers. CMBS comprise about $800 billion of the $3.4 trillion CRE debt
market. However, the structures of CRE loans (their terms, rates, etc.) are different than residential mortgages, and these
differences make the CRE market unique, varied, and complex.
Because so many different sectors of the economy participate in the CRE market, economic conditions often can have
disparate effects on different subsectors. Specific government intervention in CRE historically has been limited, largely due
to the generally limited federal role in CRE markets. Unlike residential mortgages that are often purchased and securitized by
entities linked to the federal government, commercial mortgages are generally privately securitized. Federal financial
regulators do, however, indirectly address CRE by setting the policy for bank lending to CRE markets. The regulators can
incentivize or disincentivize lending to certain sectors through prudential supervision and regulation. In addition, the Federal
Reserve can assuage market liquidity concerns by purchasing assets such as CMBS from investors.
The Coronavirus Disease 2019 (COVID-19) pandemic has created a unique environment for CRE. With many businesses
shuttered or operating on a limited basis, CRE tenants are struggling to make their payments, either in the form of rent or
mortgages. For example, restaurants and storefronts have closed down temporarily or reopened on a limited basis, placing a
strain on the retail sector. With travel limited, depressed tourism has caused hotels to lose summertime revenue. Office space
has been left vacant as many businesses have shifted to work-from-home models for their employees. Stadiums, arenas, and
sports teams have ceased operations due to cancelled tours and seasons, or they have carried on without fans, meaning no
revenue from ticket sales or concessions. Hospitals have been flooded with pandemic cases, meaning day-to-day operations
have sometimes exceeded capacity, but lucrative procedures, such as elective surgeries, have been put on hold until the health
care industry reaches a normal pace of work. Many school districts have closed, choosing to operate virtually in the coming
semester.
While financial regulators, including the Federal Reserve, have taken measures to address various impacts of the pandemic,
the 116th Congress has also considered ways to address these issues, and some of them would directly impact CRE. Many
Members of Congress have called on the U.S. Treasury and the Federal Reserve to open liquidity facilities to CRE and
CMBS markets. In addition, legislation, such as H.R. 7809 and S. 4670, were introduced to specifically provide relief to the
CRE sector by authorizing Treasury to guarantee preferred equity investments backed by CRE mortgages or make preferred
equity investments in qualifying CRE companies. Other measures, such as H.R. 6800 and H.R. 925, both of which passed the
House in 2020, would provide assistance to businesses and mortgage servicers for loans in certain CRE markets.
Future economic conditions are uncertain. The impacts of the pandemic may result in a substantially changed world for CRE,
as lenders structure deals and offer credit to commercial borrowers in new ways to address risks associated with changing
social preferences. Further, if the economic downturn from the pandemic were to become protracted, even though failed CRE
can enter private-sector bankruptcy to resolve bad debts, Congress could consider intervening and providing financial
assistance as it has in other troubled sectors.

Commercial Real Estate Market Finance
Most people interact with commercial real estate (CRE) in some way on a regular basis. Whether
they go to an office to work, eat out at a restaurant, shop at a mall or local business, or attend a
sporting event, CRE is a part of daily life. This report examines the basic structure of how CRE is
financed and explores some of the current issues that may affect the availability of finance across
the CRE sector.

The CRE market is large and complex. Because most commercial properties are owned or leased
by private companies, valuing the market is difficult, but industry analysis suggests that CRE
properties are valued around $16 trillion,1 (see Table 1 above) and outstanding CRE debt is
around $3 trillion.2 (See Figure 1 below.) Whereas businesses can take out commercial debt for
any number of reasons, including financing acquisitions, payroll or overhead costs, or inventory,
CRE financing is used to pay for the land and structure within which businesses operate. The
general distinction between CRE and residential real estate is that CRE properties are used for
generating income for its owner rather than used as a residence for its owner. CRE loans are used

for privately owned, government, and nonprofit projects.3 Common uses for CRE include office
space, retail space, hotels, stadiums, schools, hospitals, and multifamily housing.4
In some ways, CRE is financed like residential property; there is a lender and a borrower, and
mortgages generally are secured by the property (meaning that if the borrower defaults, the lender
can assume ownership of the property). However, there are key differences between commercial
and residential markets. For instance, term and down payment are distinguishing factors. To
purchase a home, a borrower typically takes out a 30-year mortgage. This mortgage fully
amortizes
, meaning that the payments are spread throughout the 30-year term. In CRE markets,
borrowers take out loans for much shorter terms, typically 3-10 years, and these loans do not fully
amortize. Instead, the borrower will make smaller payments until the end of the term, followed by
a larger payment at the end. Another key difference is the down payment. Residential borrowers
may put down anywhere from 3% to 20% of the total property value; CRE borrowers typically
put down more, around 25%.5
These differences reflect the cost structures and risks associated with developing and maintaining
commercial property. For instance, a developer has the significant up-front cost of building a
structure and will not be repaid until the property is sold or starts generating income. Lenders
therefore may require shorter terms and larger down payments to account for a potential higher
risk of default.
Types of CRE Loans
Four general types of CRE loans are conventional commercial mortgages, construction and land
development (CLD) loans, multifamily loans, and mezzanine loans.6
If a borrower wants to finance a property with a structure on it, the borrower could choose a
conventional commercial mortgage. Commercial mortgages would allow the borrower to
purchase some or all of an existing property; these loans usually have maturities of 10 years (but
can range from 5 to 30 years) and carry loan-to-value (LTV) ratios of 65%-75%.7
CLD loans finance the purchase of land, preparation of sites, and construction of buildings on
those sites. Should a borrower want to build a structure, construction loans could be taken out to
finance the development. These loans carry terms similar to a line of credit, where the borrower
would draw down funds to build and make payments over a shorter term, often in the form of
interest-only payments. CLD loans typically have maturities of three years,8 and they carry LTV

3 Commercial real estate (CRE) loans are also used to finance the construction of single-family home developments,
though not the purchase of individual homes. A developer would get a construction loan to build the houses, but the
individual homebuyers would get residential mortgages to purchase the structures and land. For more, see James
DiSalvo and Ryan Johnston, The Growing Role of CRE Lending, Federal Reserve Bank of Philadelphia, Banking
Trends, Third Quarter 2016, at https://www.philadelphiafed.org/-/media/research-and-data/publications/banking-trends/
2016/bt-cre_lending.pdf (hereinafter DiSalvo and Johnston, The Growing Role of CRE Lending, 2016).
4 Multifamily housing is considered CRE because it is operated by a company or individual seeking to profit from the
residents. While multifamily housing is a substantial part of CRE, this report is focused on nonresidential real estate,
and discussion of multifamily housing will be limited. More on multifamily housing can be found at CRS Report

ratios around 75%-85%.9 Once a construction loan term has expired, the borrower would replace
the CLD loan with a “takeout” loan to the property, which is effectively a new loan that resembles
a conventional commercial mortgage.
Loans for multifamily housing units such as apartments (referred to as multifamily loans) are
similar to commercial mortgages but often have longer maturities, ranging from 10 years to 40
years. They have LTV ratios around 75%-85% and are designated specifically for apartment
buildings that generate rental income.10
A mezzanine loan is somewhat similar to a second mortgage. It provides additional funding on
top of a first mortgage and can combine equity and debt financing. A particularly expensive
project, such as a large office building or stadium, might use a mezzanine loan to effectively
increase the LTV ratio. Mezzanine loans gained popularity in response to a combination of
factors: stricter lending standards, enhanced regulatory capital requirements, and the influence of
bond rating agencies and investors on the underwriting of the CRE loans that comprise
commercial mortgage-backed securities (CMBS), discussed below. These factors created a
lending environment with lower LTV ratios, limiting the amount of debt available for a CRE loan
and making mezzanine financing necessary for larger projects.11 Mezzanine loans are typically
junior to the first mortgage and can be structured as secured or unsecured debt or as equity.
How Do CLD Loans, Mezzanine Loans, and Commercial Mortgages Interact?
In the case, for example, of a developer who wants to build a new restaurant on land that contains an old
structure, the developer could go to a bank for a construction and land development (CLD) loan. A typical CLD
loan might be structured as a three-year line of credit, with a balloon payment at the end of the project. The
bank’s loan may provide somewhere around 80% of the financing necessary—the loan-to-value ratio for a CLD
loan can vary but typically ranges from 75% to 85%. (The rest of the financing would likely come from an
unsecured mezzanine loan.) The CLD loan funds would be disbursed in stages, typically aligned with
predetermined phases in the project development schedule. This disbursal process would protect the bank. At the
end of the construction, the developer would take out a conventional loan to pay off the CLD loan balloon
payment and then begin making payments on the longer term conventional commercial mortgage.
Managing Portfolio Risk of CRE Loans
As described above, lenders such as banks can make different kinds of CRE loans to borrowers.
However, although these loans can be profitable, they can be too large or too risky to hold in the
lender’s portfolio; thus financial institutions can distribute the risk of the loan to other investors in
a few ways.
Two similar but distinct practices that lenders use to manage loan portfolio risk are called loan
syndication
and loan participation.12 Both practices effectively reduce the amount of exposure a
lender takes on by making a loan to a borrower. For example, if a loan is too large for an

individual lender to make, that lender can join other lenders in making a syndicated loan, where
multiple lenders pool funds together to make one large loan to a borrower. However, if a financial
institution wants to serve as the primary lender for a borrower, but the loan is too large or risky
for them to make and then keep on their books, the financial institution can make the loan and sell
participations to other lenders, giving other lenders a share of the loan, and reducing the primary
lenders overall credit exposure. This way, the primary lender retains a relationship with the
borrower while avoiding unwanted credit exposures.
Another practice that has grown considerably in the past few decades for CRE is for lenders to
sell a loan they make into the secondary market, where it can be securitized and packaged as a
CMBS. This transaction provides the lender with more cash (liquidity) to make new loans and
transfers credit risk to the secondary market where investors can purchase an interest in a security
that matches their risk tolerance and demand for returns.
The different sources of CRE financing are broadly illustrated in Figure 1. While lenders can sell
loans into the secondary market at any time (meaning they can hold loans in their portfolio as
long as they wish), this figure gives a reasonable snapshot of the balance of funding sources for
CRE. Banks and thrifts keep about 39% of the outstanding CRE market debt in portfolio, whereas
private label CMBS issuance comprises about 14% of the market.

Commercial Mortgage-Backed Securities
An asset-backed security (ABS) is a type of financial instrument that derives its value from a pool
of loans, such as auto loans or mortgages. A mortgage-backed security (MBS) is a type of ABS
that comprises a pool of mortgages. Similarly, a CMBS comprises commercial mortgages. Some
CRE mortgages, known as CMBS loans or “conduit loans” are designed to be securitized and
sold in the secondary market. CMBS loans can be attractive to borrowers because they can carry
lower rates than traditional CRE mortgages and allow borrowers flexibility in transferring or
prepaying their mortgages. Some financial institutions specialize in making CMBS loans to
borrowers and selling them to investors.13 Typically, life insurance companies, pension funds,
money managers, mutual funds, and commercial banks invest in CMBS products.
Figure 1 shows that private securities backed by commercial mortgages and real estate comprise
around 14% of the total CRE lending market. MBS for CRE constitute over a third of the market
after adding the multifamily (i.e., properties with five or more residential units) portfolios and
securitized issuances from Fannie Mae and Freddie Mac (collectively referred to as the
government-sponsored enterprises, or GSEs) and Ginnie Mae.14
CMBS markets developed substantially over the past three decades. A short history of how this
market evolved is presented in the Appendix.
The Federal Role in CRE Finance
Although the federal government created an impetus for the modern CMBS market, the federal
role in CRE is relatively limited, especially in nonresidential properties.15 That said, some federal
agencies guarantee, insure, or securitize certain types of CRE loans. For example, the U.S. Small
Business Administration (SBA) has programs that guarantee repayment of portions of eligible
small commercial loans designed for fixed asset investments, which can include machinery or
CRE.16 Further, federal financial system regulators have issued rules that impact CRE, and the

13 For example, see Susan J. Booth, “The Unique Aspects of CMBS Loans: A Primer for Borrower’s Counsel,” January
17, 2019, at https://www.mondaq.com/unitedstates/leasing/772076/the-unique-aspects-of-cmbs-loans-a-primer-for-
borrower39s-counsel.
14 Fannie Mae and Freddie Mac were created by Congress to provide liquidity to residential markets. They do this by
purchasing and securitizing loans. While they are private enterprises, in 2008, both institutions were brought under
conservatorship by the Federal Housing Finance Agency (FHFA). More on the government-sponsored enterprises can
be found at https://www.fhfa.gov/SupervisionRegulation/FannieMaeandFreddieMac/Pages/About-Fannie-Mae—
Freddie-Mac.aspx.Ginnie Mae is a government agency that guarantees investors the timely payment of principal and
interest on mortgage-backed securities (MBS) backed by federally insured or guaranteed loans. This includes loans
insured by the Federal Housing Administration (FHA) or guaranteed by the Department of Veterans Affairs (VA).
Other guarantors or issuers of loans eligible as collateral for Ginnie Mae MBS include the Department of Agriculture’s
Rural Development (RD) and the Department of Housing and Urban Development’s Office of Public and Indian
Housing (PIH). For more on Ginnie Mae, see https://www.ginniemae.gov/about_us/who_we_are/Pages/
funding_government_lending.aspx.
15 The federal government does have a substantial presence in multifamily housing markets. For instance, the Federal
Housing Administration (FHA) insures certain multifamily loans. The U.S. Department of Agriculture (USDA)
guarantees (and can issue) rural multifamily loans. Ginnie Mae securitizes these FHA and USDA loans. Additionally,
the GSEs have lending programs that focus on multifamily housing.
16 The U.S. Small Business Administration’s (SBA’s) 504 Loan Program makes funds available for purchasing or
improving land or owner-occupied buildings. For more, see SBA, “U.S. Small Business Administration Loan Funds
Available to Purchase Commercial Real Estate,” at https://www.sba.gov/offices/headquarters/ofa/resources/4049. For

Federal Reserve has implemented asset purchase programs that include CMBS.17 However, these
interventions are not necessarily to provide relief specifically to CRE markets, but instead to
provide support to the financial system. In general, the federal government has not had a
permanent presence in most traditional CRE markets.
Federal Regulation
Federal regulators generally have a limited and sometimes indirect role in nonresidential CRE
finance. As Figure 1 suggests, banks are a significant provider of CRE finance. To the extent
banks are lending to CRE borrowers, they are subject to a range of federal banking supervision
and prudential regulations. Federal bank examiners also have specialized guides for how to treat
CRE.18 Because CMBS products are securities, they are subject to regulation by Securities and
Exchange Commission (SEC),19 as well as the banking regulators,20 the Department of Housing
and Urban Development (HUD), and the Federal Housing Finance Agency (FHFA). The next
sections of report discuss regulations adopted after the 2007-2009 financial crisis, Regulation RR
and Regulation AB.
Risk Retention Rule (Regulation RR)
In 2010, Congress passed the Dodd-Frank Wall Street Reform and Consumer Protection Act
(Dodd-Frank Act; P.L. 111-203), which among many other things, required skin in the game for
nonresidential asset-backed securities. In 2014, the banking regulators, the SEC, HUD, and FHFA
adopted a rule implementing credit risk retention standards for ABS, including CMBS. The
regulation is known as Regulation RR and requires issuers to retain at least 5% of any security
they issue on their books.21 The rule contains exceptions for “qualified commercial real estate
loans,” which are deemed to have well-documented and prudent terms and a creditworthy
borrower.22



17 Notably, the Federal Reserve included CMBS in its asset-backed security liquidity facilities during the aftermath of
the 2007-2009 financial crisis and in the economic fallout of the Coronavirus Disease 2019 (COVID-19) pandemic.
18 For example, see OCC, Comptroller’s Handbook, “Commercial Real Estate Lending” section, 2017.
19 The laws that give the Securities and Exchange Commission (SEC) the authority over asset-backed securities (ABS)
are discussed in more detail in CRS In Focus IF10032, Introduction to Financial Services: The Securities and
Exchange Commission (SEC)

20 The FDIC, the Federal Reserve, and the OCC comprise the banking regulators.

2018).
22 See DiSalvo and Johnston, Skin in the Game in the CMBS Market, 2018. Qualifying CRE loans are defined in
Regulation RR as having a fixed-rate loan with a minimum maturity of 10 years and a maximum amortization of 25
years (30 for loans secured by multifamily properties). Additionally, the two years of the property’s income is
documented by the lender, and the borrower’s debt service ratio must not exceed 1.25% for multifamily properties,
1.5% for leased properties, and 1.7% for all other loans. Also, the combined LTV ratio of all loans on the property
cannot exceed 70%, and the LTV ratio of the first lien loan cannot exceed 65%. For more, see OCC, Federal Reserve,
FDIC, Federal Housing Finance Agency, SEC, and Department of Housing and Urban Development, “Credit Risk
Retention,” 79 Federal Register 77601-77766, December 24, 2014.

Commercial Real Estate Finance


Legacy CMBS Versus CMBS 2.0
After the 2007-2009 financial crisis, lending and underwriting standards became more conservative in response to
enhanced prudential regulation, lender concerns over creditworthiness, and investor concerns over transparency.
Legacy commercial mortgage-backed securities (CMBS) is a term that refers to CMBS issued prior to 2009, and CMBS
2.0
refers to those issued after 2009. The general difference between these two types of mortgages is that Legacy
CMBS have lower “subordination,” which means there would be less cushion if an investor were to take a loss.
More cushion is a credit enhancement, meaning, from an investor’s perspective, the CMBS 2.0 would be safer
because the issuer retains some of the risk.
Asset-Backed Securities Disclosure and Registration (Regulation AB)
On January 7, 2005, the SEC issued a final rule that clarified the requirements for registration,
disclosure, and reporting for ABS, which include CMBS.23 With respect to CMBS, Regulation
AB impacts the institutions that service CMBS transactions (referred to as servicers) and the
process by which information is disclosed to investors. The Dodd-Frank Act directed the SEC to
require issuers of ABS to disclose asset-level or loan-level data to enable investors to perform due
diligence, among many other things. In 2014, the SEC issued a final rule to revise Regulation AB,
commonly referred to as Reg AB II, to developed asset-level disclosure requirements.24 Further
updates to Reg AB II after 2014 amended disclosure requirements and the structure of CMBS
transactions.25
Policy Issues for the 116th Congress
One of the most pressing issues currently facing the 116th Congress is how to address the various
economic impacts of the COVID-19 pandemic. The pandemic has created a unique challenge for
CRE—with many businesses shuttered or operating on a limited basis, CRE tenants, particularly
retail businesses, are struggling to make their payments, either in the form of rent or mortgages.26
For example, restaurants and storefronts have closed down temporarily or reopened on a limited
basis, placing a strain on the retail sector. With travel limited, depressed tourism caused hotels to
lose summertime revenue. Office space has been left vacant, as many businesses have shifted to
work-from-home models for their employees. Stadiums, arenas, and sports teams have ceased
operations due to cancelled tours and seasons, or they have carried on without fans, meaning no
ticket sales or concession revenue. Some hospitals were flooded with pandemic cases, meaning
day-to-day operations have sometimes exceeded capacity, but lucrative procedures, such as
elective surgeries, were put on hold until the health care industry reaches a normal pace of work.
Many school districts have closed, choosing to operate virtually, or switched to a hybrid model of
virtual and in-person classes.

among retail locations in April and May. Conversely, industrial and office tenants have maintained a relatively high
rate of rental payments. For more, see Goldman Sachs, “US Daily: Have Businesses Paid Their Rent During the

In June 2020, CMBS delinquency rates hit almost peak levels, with 10.32% over 30 days past
due. This is near the previous peak of 10.34% in 2012. As can be seen in Figure 2, the rate fell in
July and August to 9.02% but remains considerably higher than pre-pandemic levels. These
elevated levels are driven by delinquencies in lodging (22.96%) and retail (14.88%).27

Pandemic Policy Response for CRE and CMBS
Most of the pandemic policy response regarding real estate has centered on residential real estate,
resulting from the strong federal presence in the U.S. housing market. For instance, almost two-
thirds of residential mortgages are backed by congressionally chartered Fannie Mae or Freddie
Mac (the GSEs), and a significant portion of non-GSE mortgages are guaranteed or insured by
various federal agencies. The Coronavirus Aid, Relief, and Economic Security Act (CARES Act;
P.L. 116-136) tied much of the residential mortgage relief to mortgages with federal government
support.28 The support under the CARES Act also includes some forbearance relief for
multifamily mortgage borrowers with federally backed loans; however, no explicit protections are
granted to nonresidential CRE borrowers.
Nonresidential CRE policy considerations differ from those pertaining to residential mortgages,
where a primary policy goal is often to reduce the number of families who lose their homes. In
the CRE market, the policy questions tend to focus on to what extent federal intervention may, in
the hopes of avoiding potential future systemic risks, mitigate losses that would otherwise be
borne by the private sector. For instance, a prolonged economic downturn may lead to businesses

such as retail stores and restaurants earning less income. To the extent these businesses are
commercial mortgage borrowers, this jeopardizes their abilities to make their payments. If they
are tenants, this means the borrowers are now likely to receive less income and may struggle to
make mortgage payments. When the mortgage payments are not made, the loans become
delinquent—at some point, the business may seek foreclosure or bankruptcy—and lenders of
CRE mortgages and investors in CMBS instruments are at risk of taking losses. As long as access
to bankruptcy proceedings and foreclosure is not impeded, borrowers can work out their debts
with the lenders and some losses can be recouped. However, while investors in CMBS select the
returns associated with their risk tolerance for taking losses, if an entire industry were to face
spikes in defaults that relied heavily on CMBS financing, it could cause liquidity issues in a
market that is important for providing credit to many other commercial borrowers. Further, while
a default on an individual loan is not sufficient to cause broad economic impacts, if the rate of
defaults increases significantly across industries, this could stress investors in CMBS and
jeopardize liquidity in CRE financing markets.

Negative Externalities, Systemic Risk, and Market Failures
Public policy intervention in the form of financial assistance is often used as a way to offset negative externalities,
address systemic risk, or account for market failures.
Negative externalities occur when the production or consumption of a good or service causes harm to a third
party. In other words, if the costs are not borne by those in the market for a good or service, then there are
negative externalities. This is a type of market failure. For example, consider a concert venue that gathers
thousands for an event during the pandemic and becomes a “super-spreader” event where the pandemic spreads
to many of the attendees. In this case, the cost of managing the virus (tests, hospitalizations, quarantines, leave
from work, etc.) are not solely borne by the attendees.
One question of particular importance is whether CRE poses a systemic risk. Systemic risk refers to the risk
that some development wil cause widespread financial instability. For example, the 2007-2009 financial crisis
highlighted the interconnected nature of various financial institutions and the industries that depend on financing
to remain liquid. Figure 1 above shows that about 39% of CRE loans, more than $1 tril ion, are held in bank
portfolios. Many businesses depend on financing to remain liquid and make their bil s. However, as business
balance sheets deteriorate from lower economic activity, the outstanding loans may begin to enter delinquency.
The extent to which this could have a systemic impact on financial institutions depends on a number of factors,
including the leverage and liquidity profiles of the market. While today’s commercial mortgage markets, including
commercial mortgage-backed securities, are smaller, less leveraged, and more liquid than the troubled residential
mortgage markets of over a decade ago, the 2007-2009 financial crisis shows how a class of assets (e.g. residential
mortgage-backed securities) can pose systemic risk.
Although systemic risk is generally associated with the financial system, if policymakers choose
to intervene, they could address potential losses faced by lenders and investors, or losses by the
commercial business, or some combination of the two. Some of the current policies in places are
discussed below.
Existing Indirect Support for CRE and CMBS Finance
Although there is currently no relief program dedicated to CRE, the broad policy response to
COVID-19 includes some indirect support to CMBS markets. The Federal Reserve’s response to
the pandemic supported CMBS markets in two ways.29 First, as part of its “quantitative easing,”

29 The Federal Reserve took similar actions during the 2007-2009 financial crisis. More on the Federal Reserve’s policy

the Federal Reserve has directly purchased CMBS that comprise federally backed multifamily
mortgages.30 Second, private CMBS are eligible for purchase through the Term Asset Backed
Securities Liquidity Facility (TALF), a program to support the non-residential ABS market
generally.31 As of September 30, 2020, TALF included 107 private CMBS loans with an
outstanding value of just over $1 billion.32 Although these actions boost demand for CMBS, they
do not directly address the losses faced by the industry and they comprise a relatively small
portion of the Federal Reserve’s activities. As of September 23, 2020, agency CMBS—those
multifamily housing CMBS backed by the GSEs or federal government—comprised less than 1%
of the Federal Reserve’s System Open Market Account holdings.33 Additionally, provisions in the
CARES Act provide regulatory relief to the financial system, which may enable it to meet the
needs of distressed CRE borrowers. For instance, the CARES Act reduces the Community Bank
Leverage Ratio for two years, making it easier for lenders to workout problematic loans.34
CRE also may benefit from the Federal Reserve’s emergency programs or some of the programs
established by the CARES Act, but limitations on these programs have made it difficult for some
CRE businesses to participate. For example, if an eligible CRE company were to issue
commercial paper or corporate bonds, it could benefit from Federal Reserve programs that
purchase them. Large CRE companies are likely to be the most active issuers in securities
markets. The Federal Reserve also created the Main Street Lending Program (MSLP) to offer
loans with repayment deferment for smaller companies. However, CRE industry members have
noted the MSLP is not well suited to their business model, due to the programs limitations.35
Likewise, some small CRE businesses already may have access to the SBA’s Paycheck
Protection Program (PPP).36 The eligibility of many CRE companies depends on whether they are
considered “eligible passive companies.”37 In addition, PPP may enhance other small businesses
recipients’ abilities to make rental payments to CRE landlords.

30 On March 23, 2020, the Federal Reserve’s Federal Open Market Committee (FOMC) announced that it would
purchase Treasury securities and agency MBS in the amounts needed to support smooth market functioning and
effective transmission of monetary policy to broader financial conditions and would include agency commercial MBS
in its purchases of agency MBS. For more, see Federal Reserve, Report on the Federal Reserve’s Balance Sheet,

Legislative Proposals
Recently, some Members of Congress have called for financial assistance to be more widely
available to CRE and CMBS markets. For instance, Senate Committee on Banking, Housing, and
Urban Affairs Chairman Mike Crapo issued a letter in July to Treasury Secretary Steven Mnuchin
and Federal Reserve Board Chairman Jerome Powell encouraging them to expand the emergency
lending programs associated with the pandemic by establishing a commercial real estate
program.38 Efforts targeting CRE face a few challenges. As mentioned earlier, the pandemic has
had disparate effects on various CRE subsectors. For instance, the pandemic has perhaps had a
more significant impact on tourism and retail than on other subsectors. Thus, to the extent
Congress is interested in providing support to these subsectors, it may consider how to craft a
policy that benefits those borrowers specifically.
Potential recipients of direct financial assistance include tenants, borrowers, loan servicers, or
lenders and investors, and each has important considerations:
 Financial assistance such as grants or loans directed at businesses generally could
help commercial tenants meet their financial obligations, thus lowering the
chances that a commercial tenant becomes insolvent. There are procedures in
place to manage commercial insolvency through the bankruptcy code. This is to
say that there is no general market failure simply because specific businesses
becomes insolvent. In fact, a company may be able to remain a going concern by
working their debts out with their lender through bankruptcy. But even if it
cannot, a business closure is part of a functioning market. However, during a
pandemic, where widespread business closures and limitations on operations are
causing many companies to lay off employees and cut costs, Congress may seek
to avoid the negative externalities of unemployment and economic decline by
providing support directly to businesses.
 Alternatively, Congress may focus support on the mortgage borrowers,39 through
loan forbearance programs, debt relief measures, or additional loans or other
financial assistance. These measures face some structural challenges. Efforts
targeting borrowers face challenges with the legal contracts that private
companies sign with lenders. For example, as can be the case in some industries,
agreements in contracts called loan covenants are often structured to prohibit or
limit a borrower’s ability to take on additional debt, as this could reduce the
likelihood of a lender being repaid. This means that such borrowers would be
breaking their contractual obligations if they were to accept financial assistance
in the form of a loan from the Federal Reserve or another entity. Alternatively,
temporary financial relief measures such as loan forbearance could help
businesses remain in their leases or mortgages but would transfer some of the
losses temporarily to the financial system.
 Assistance targeting mortgage services, lenders, and investors of CRE loans and
CMBS may seek to keep liquidity in financing markets through the Federal
Reserve, which can provide loans to financial institutions or purchase assets such
as CMBS from investors. This may not directly address the cash shortfall of the

businesses affected by the crisis, but acts as a backstop to keep financial
institutions and investors in a position to continue providing funds to the market.
Some legislation has been introduced that would directly impact CRE and CMBS markets and
provide examples of the unique characteristics of the market. In May 2020, the House of
Representatives passed the Heroes Act (H.R. 6800), aimed at providing another round of financial
relief for people and businesses affected by the pandemic. Many of the provisions in the Heroes
Act expand and amend the PPP program to make more funds available to small businesses.40 In
addition, the Heroes Act would require the Treasury Secretary to ensure that servicers of federally
backed mortgages can participate in Federal Reserve programs backed by CARES Act funds as
long as Federal Reserve assistance is used for borrower assistance (e.g., loss mitigation and
forbearance), among other requirements.41 This would apply to multifamily housing mortgages.
Further, the bill would establish a forbearance program for loans to small businesses and would
require the Federal Reserve to create a similar facility for creditors and debt collectors
participating in the forbearance program. A second Heroes Act (H.R. 925), passed by the House
in October 2020, includes, among other things, language substantially similar to the provisions
from H.R. 6800 mentioned above.
Although these efforts are aimed broadly at providing relief to consumers, renters, borrowers, and
servicers, other legislation would provide more specific assistance to the financing markets for
CRE. For instance, in July, Representative Van Taylor introduced H.R. 7809, which would
establish a sort of liquidity facility in Treasury to assist commercial mortgage borrowers. Unlike
other forms of liquidity assistance offered by the Federal Reserve in the form of loans, as
described above, this facility would provide funding through preferred equity purchases.
In many ways, this assistance would work similarly to a mezzanine loan, but by altering the
structure slightly and issuing preferred equity, it could allow CRE and CMBS borrowers to
receive assistance without breaching the loan covenants in their legally binding contracts.42 The
preferred equity assistance would be available to borrowers who might experience a drop in
revenue of at least 25% in a three-month period between March 2020 and February 2021,
provided that they meet certain financial conditions. The equity instrument, which could be equal
to 10% of the outstanding commercial mortgage, would operate similar to a line of credit with a
one-year drawn down period and a fixed interest rate of 3%, with payments amortized over seven
years. The instruments would be issued by financial institutions and guaranteed by Treasury;
additionally, Treasury would provide origination fees to institutions to incentivize participation.
Preferred equity is also used in S. 4670, introduced in September by Senator Jerry Moran, which
would amend the CARES Act to authorize Treasury to make preferred equity investments in CRE
companies that require capital to meet their debt obligations. The bill allows Treasury to make
these investments alone, or in concert with the Federal Reserve, by directly purchasing preferred
equity positions in the eligible CRE companies, or by providing full or partial guarantees to
financial institutions that purchase such positions.43 The bill would also instruct the federal

The future of many commercial real estate properties is uncertain. For instance, it remains to be
seen how quickly storefronts, restaurants, hotels, stadiums, and office spaces return to full
capacity, or even whether full capacity returns to pre-pandemic levels. As of now, many
legislative efforts are targeting the businesses that have suffered losses due to shutdowns, social
distancing, limited capacity, and remote operations, but if an economic downturn persists, stresses
on the commercial sectors may begin to bleed into the financial markets, leading to liquidity

markets.

Appendix. Historical Evolution of Commercial
Mortgage-Backed Securities
This appendix provides some background on how commercial mortgage-backed securities
(CMBS) came to exist in its current form, and it is divided into three parts. The first part
discusses a range of mortgage-backed securities for illustrative purposes. The second part
examines how government intervention catalyzed CMBS growth. The third part explains the two
most common forms of CMBS today.
Basic MBS Structures
Bonds backing commercial mortgages date back to the 1920s, but these arrangements were
simpler than today’s mortgage-backed securities (MBS) markets.45 A few basic kinds of MBS
serve as a foundation for what is now a complex and specialized financial market for CMBS. For
instance, a mortgage pass-through security (MPS) is a securitization process whereby a mortgage
is sold into a trust that issues securities backed by the underlying mortgage. In this example, the
mortgage payments made by the borrower would pass through the trust to the investor, effectively
giving the security and the underlying mortgage the same payment schedules. The loan issuer
would sell the mortgage off the books to the trust, and the investor would receive cash flows that
mirror the mortgage payments. Another example is a mortgage-backed bond (MBB), which
creates a fixed-term instrument with a fixed payment schedule (referred to as a “coupon
payment”). The loan issuer would keep the mortgage on the books, and the investor would
receive coupon payments on a fixed schedule that differ from the mortgage payments.
A collateralized mortgage obligation (CMO) is an alternative to MPS and MBB instruments.
CMOs are what are referred to as “multiclass pass-through” instruments.46 In such an instrument,
multiple mortgages are passed through to a trust, and the payments of principal and interest of all
of these mortgages creates the basis for the cash flows for the investors. The trust would issue
multiple classes of securities that have varying terms and levels of priorities (or seniority) over
the claims to these cash flows. Tax treatment of these instruments throughout the 1980s meant
that CMO issuers had to treat the instrument as debt, keeping the CMO on their balance sheets as
liabilities and paying taxes on their interest incomes.47 (An incentive to issuing CMOs over MPSs
was that the pass-through payments were collateralized by the principal and interest payments of
the multiple mortgages rather than the entire single mortgage, meaning that an issuer could hold
less equity in a CMO than in an MPS.)

Government Intervention: Tax Law, the RTC, and Modern CMBS
Prior to the 1980s, neither MPSs, MBBs, nor CMOs allowed both the issuers to sell the
mortgage(s) off their books and the investors to achieve differing cash flows from the underlying
mortgage. The Tax Reform Act of 1986 (P.L. 99-514) permitted the creation of Real Estate
Mortgage Investment Conduits (REMICs) in an effort to clarify how trusts that hold mortgages
and issue securities would be treated under tax law.48 The Tax Reform Act of 1986 (P.L. 99-514)
allowed REMIC issuers to avoid the income taxes of CMOs by transferring the tax liability to the
holder of the securities (the investors).49 Under the law, REMIC issuers can treat the underlying
loans as a sale of an asset, rather than a debt. This means that REMICs allowed MBSs to meet the
interests of issuers who wanted to clear their balance sheets, as well as investors who wanted cash
flow diversification. Today, CMOs are issued in REMIC form, and the terms are used
interchangeably.50
In the 1980s, lenders and investors became increasingly interested in the potential benefits of
securitization.51 It was not until the 1990s, however, that traditional commercial mortgages began
to dominate the financing options for commercial property borrowers. This was in part due to the
beneficial tax treatment for REMICs set forth in the Tax Reform Act of 1986, described above.
Another piece of legislation helped increase the demand for CMBS. In the late 1980s, a financial
crisis resulted in the collapse of the savings and loan industry. In response to the financial turmoil,
Congress passed a series of laws, including the Financial Institutions Reform, Recovery, and
Enforcement Act of 1989 (FIRREA; P.L. 101-73), which established the Resolution Trust
Corporation (RTC) primarily to receive and resolve failed thrift institutions, among other things.52
While this report generally focused on nonresidential commercial loans, multifamily loans are
important to the creation of modern CMBS structures. For example, thrift institutions primarily
focused on residential lending, and they originated a sizeable portfolio of commercial mortgages
in the form of multifamily loans in the 1980s; so as failed thrifts entered RTC conservatorship,
the RTC took over these commercial loan portfolios. It is through the models created by
residential multifamily finance that CMBS took its modern form.
The RTC, a federal agency with a statutorily limited term of existence, ultimately operated from
1989 to 1995 and is credited with expanding the commercial securitization marketplace. Prior to
1990, commercial securitization took on simple forms similarly to the products mentioned in the

archive/realestate/1987/01/03/remics-to-boost-mortgage-market/1e65de22-dedd-4fc2-a290-e5a94f54c397/.
49 This tax benefit was created by allowing Real Estate Mortgage Investment Conduits (REMICs) to divide the flow of
mortgage payments into varying classes of securities in a manner that exempted them from the definition of an “active
manager.” More on the Tax Reform Act of 1986 (P.L. 99-514) and the tax treatment of REMICs can be found at CRS

51 Although the financial crisis of 2007 highlighted some of the inherent risks of securitization, lenders can benefit from
effectively selling a loan or multiple loans off of their balance sheets, and investors can derive new patterns of cash
flows and diversification.

receiverships and to facilitate sales to qualified parties. See Federal Deposit Insurance Corporation (FDIC), Managing

section above. By 1990, the RTC had been appointed conservator for over 500 thrifts. This
workload complicated one of the main challenges the RTC faced: selling assets quickly at a fair
price—in 1991, FIRREA was amended to facilitate quicker sales.53
In response, the RTC created structured transaction programs and new securitization markets for
less traditional assets, including commercial loans, which allowed it to dispose of large volumes
of assets at more reasonable prices. For example, in 1991, to boost demand for commercial assets
held by failed thrifts, such as multifamily and commercial mortgages, the RTC created a
Structured Transaction Program. The program allowed the RTC to offload portfolios of 50-100
commercial loans at a time.54 In 1992, the RTC began its commercial mortgage securitization
program.55 This program built on the simpler securitization models that were available through
the 1980s and set the foundation for the modern, complex CMBS marketplace. The RTC
securitization program pooled several mortgages together through a REMIC structure and
facilitated the sale of CMBS securities.
Although the RTC had government support,56 enabling it to carry out these transactions, by the
mid-1990s, RTC commercial mortgage securitizations were firmly a part of the financial market
for commercial funding.57 In 1990, the commercial securitization was around $6 billion; by 1997,
the market grew to $80 billion.58 After the RTC’s operations ended in the mid-1990s, the banks
that partnered with the RTC to help bring the securities to market began issuing their own private-
label CMBS; these CMBS products comprise the majority of CMBS issuance today.59 By 2007,
roughly a third of outstanding commercial mortgages were financed through CMBS loans,
peaking around $775 billion in CMBS outstanding.60 CMBS outstanding has fallen since its peak
before the 2007 financial crisis, stabilizing around $547 billion in the first quarter of 2019.61 In
2019, annual issuance of private-label CMBS stood around $100 billion, and total private-label
CMBS outstanding was around $490 billion as of March 2020.62

53 The Financial Institutions Reform, Recovery, and Enforcement Act of 1989 (FIRREA; P.L. 101-73) “included
language requiring the RTC to sell real estate for no less than 95 percent of its appraised (market) value. In 1991, in
response to growing criticism about low sales and congressional concern with the cost of maintaining the rapidly
growing inventory of properties, FIRREA was amended to reduce the minimum sales price to no less than 70 percent of
appraised value.” See FDIC, Managing the Crisis, “Executive Summary” section, pp. 9-10.
54 FDIC, Managing the Crisis, p. 318.
55 FDIC, Managing the Crisis. The RTC began its securitization program in 1992. A U.S. Congressional Budget Office
(CBO) Staff Memorandum from July 1992 suggests the RTC issued securitized mortgages in 1990—it is possible these
were residential, not commercial, mortgages. For more, see CBO, CBO Staff Memorandum: The RTC’s Loan

investors would face losses only if defaults exceeded the portion of the security that the RTC retained.

Conduit Versus Single-Asset/Single-Borrower CMBS
Today, CMBS generally come in two basic forms: conduit and single-asset/single-borrower
(SASB), which together comprise about 90% of outstanding CMBS. Conduits are securitizations
of a large number of CRE mortgages, with fairly standardized characteristics. For example,
conduits are typically around $1 billion dollars, comprising 50-100 loans with fixed payments and
maturities around 10 years. The top 10 largest loans comprise around 50% of the collateral, and
the properties are typically fully leased and have stable cash flows.63
Alternatively, SASB transactions can be secured by a single asset or portfolio of assets owned by
a single borrower, and these securities vary broadly. SASB transactions are smaller on average
than conduits, ranging from $100 billion up to $1 billion.64 The underlying asset can have
variable or fixed rates; the terms and maturities also can vary. SASB transactions potentially are
riskier than conduits but provide sufficient variation to meet the different demands of different
investors.
Prior to the 2007-2009 financial crisis, conduit loans comprised the overwhelming share of
outstanding CMBS and CMBS issuance. The economic impact of the crisis reduced CMBS
