Stablecoins: Legal Issues and Regulatory 
Options (Part 1) 
June 9, 2022 
In 2008, the pseudonymous Satoshi Nakamoto released a
 white paper describing a peer-to-peer system of 
electronic cash. The product of that paper—Bitcoin—now boasts a
 market capitalization of roughly $600 
billio
n. Other cryptocurrencies amount to more than $700 billion, bringing the overall crypto ecosystem 
in line with the GDPs of many large countries.  
Despite this meteoric rise, cryptocurrencies have yet to exhibit a defining feature of cash
: widespread use 
as a medium of exchange. One reason for that failure is volatility. Most cryptocurrencies have exhibited 
wild fluctuations that may make them unattractive instruments for day-to-day purchases of goods and 
services.  
Enter stablecoins—cryptocurrencies whose value is
 pegged to a reference asset like the U.S. dollar. While 
stablecoin issuers attempt to maintain these pegs i
n different ways, most of the regulatory attention has 
focused on coins that are putatively backed with reserves of assets denominated i
n fiat currency. Often, 
those assets underwrite an issuer’
s commitment to redeem its stablecoins for a fixed value upon demand.  
That structure raises
 familiar risks. Like banks and money market mutual funds (MMFs)—the principal 
sources of private money—stablecoin issuers ar
e vulnerable to runs if their customers
 lose faith in the 
adequacy of the assets backing their demandable liabilities. Unlike banks and MMFs, however, most 
stablecoin issuers are not subject to
 federal regulations and protections designed to instill faith in those 
liabilities, such as deposit insurance and portfolio restrictions.  
Policymakers have taken notice. In November 2021, the President’s Working Group on Financial Markets 
recommended that Congress enact legislation limiting stablecoin issuance to insured depository 
institutions. Other commentators have advocated
 different regulatory strategies, ranging from a bespoke 
federal licensing regime to an outright ban on stablecoin issuance.  
This Legal Sidebar—the first part of a two-part series—provides an overview of the existing regulatory 
framework governing stablecoins. The second part discusses proposals for legislative reform of that 
framework. Both parts focus on stablecoins that are ostensibly backed one-to-one with reserves of 
fiat-denominated assets. For a discussion of algorithmic stablecoins, which instead aim to maintain their 
pegs using algorithmically determined supply adjustments or arbitrage mechanisms involving other

Tierno, Andrew P. Scott, and Eva Su.  
Background 
Banks and MMFs: The Incumbent Money Issuers 
Money is
 a fluid concept. Today, it plainly encompasses physical currency like the notes and coins 
produced by the Treasury Department. The bulk of the money supply, however, consists of
 liabilities 
issued by private entities. While the precise boundaries of money issuance are contested, the
 biggest 
private players are banks and MMFs.  
Both types of institution share a similar structure. Banks primarily fund themselves wit
h short-term 
deposits while investing in longer-term, less liquid loans. Likewise
, prime MMFs issue
 short-term 
liabilities to shareholders while investing in less liquid debt instruments with slightly longer maturities.  
This process of “maturity transformation”
 can create social value, but also makes
 banks and
 MMFs 
vulnerable to runs. If depositors or investors lose confidence in the value of the assets backing an 
institution’s demandable liabilities, they may
 rush to redeem their funds. The firm must then
 sell assets to 
meet those redemptions, potentially at steep discounts. The resulting losses may drive a bank into 
insolvency or cause
 MMFs that promise to redeem their shares at a fixed price to default on that 
commitment. In both cases, runs on individual institutions can
 trigger knock-on effects as creditors begin 
to question the safety of other firms with similar asset portfolios.  
This vulnerability raises the question: why are bank deposits and
 MMF shares regarded as safe assets that 
function as 
“good money”? Part of the answer is
 regulation. Banks are subject to a comprehensive legal 
regime that includes
 capital a
nd liquidity requirements,
 deposit insurance, access to emergency loans, and 
special resolution procedures. MMFs face fewer regulatory requirements but are likewise subject to 
portfolio restrictions and liquidity rules. These regulations hel
p bolster the credibility of the monetary 
liabilities issued by banks and MMFs and limit the destabilizing effects of runs on both classes of 
institution.  
Stablecoin Providers: Aspiring Money Issuers?  
Stablecoin issuers
 resemble banks and MMFs in important ways. Issuers 
“mint” stablecoins in exchange 
for fiat currency from investors. Investors can then
 hold the stablecoins, trade them on the open market, or 
(in many cases) redeem the stablecoins for fiat currency from the issuer. While the details of specific 
redemption options differ from coin to coin
, many issuers promise or suggest that investors can redeem 
their stablecoins at par on demand. To instill faith in their ability to meet redemptions, many providers 
advertise that their stablecoins are backed one-to-one with reserves of fiat-denominated assets.  
Like banks and some MMFs, then, many stablecoin issuers promise to return customer funds at a fixed 
value on demand, while investing those funds in a range of financial assets. Unlike banks and MMFs, 
however, most stablecoin issuers are not subject to
 federal regulations governing the composition of those 
reserve assets. Similarly, federal law does not
 require stablecoin providers to disclose details concerning 
their reserves.   
The quality of the relevant portfolios varies widely—as does the level of detail that issuers offer their 
investors
. Some stablecoin providers claim to invest primarily or exclusively in U.S. Treasury securities 
and accounts at insured depository institutions.
 Others offer less clarity on the composition of their 
reserves and reportedly invest in riskier instruments like commercial paper, corporate bonds, intra-group 
debt, and digital assets.

While this opacity raises investor-protection concerns, the extent to which stablecoins pose broader risks 
to financial stability is
 disputed. As of yet, stablecoins are not
 widely used to purchase goods and 
services. Instead, they are mainly
 employed to facilitate the trading, lending, and borrowing of other 
digital assets.  
Based on these relatively narrow use cases, some have argued that stablecoins
 do not currently pose risks 
to the financial system, even if they may raise dangers within the crypto economy. In this view, 
stablecoins are tantamount to 
“the lobby of the casino that is crypto speculation.” Some observers have 
suggested that this “casino” is well-contained and that the metaphorical “gamblers” understand the 
relevant risks, making it unlikely that the failure of a stablecoin issuer would have significant spillover 
effects for traditional financial institutions or the real economy.  
Others disagree.
 Stablecoin skeptics have focused on the rapid growth of these novel instruments over the 
past two years. (In April 2020, the market capitalization of all stablecoins
 amounted to roughly $8.3 
billion; by April 2022, that figure
 topped $180 billion—an increase of over 2,000 percent.) Some 
stablecoin providers have also become major players in certain asset classes. For example, in June 2021, 
the 
Financial Times reported that Tether—the issuer of the largest stablecoin—had amassed the seventh-
largest portfolio of commercial paper in the world.  
This dramatic expansion raises the prospect that stablecoin providers may ultimately
 become key 
participants in short-term funding markets, in which case a large issuer’s failure could have systemic 
consequences. Several providers also have
 ambitions for their coins to be widely used for retail purchases, 
supply-chain payments, and international remittances—tasks that would further entangle stablecoins with 
the broader financial system. 
Current Law  
The regulations governing a stablecoin issuer depend in part on the issuer’s legal form. Some stablecoin 
providers are chartered as
 trust companies under state or federal law. Unlike full-service banks, these 
issuers are typically not
 required to obtain deposit insurance. Capital requirements for such providers
 vary 
among different chartering authorities.  
Other stablecoin issuers are regulated as 
“money services businesses” (MSBs). State MSB regulations 
includ
e certain prudential rules to minimize the risk of an MSB’s failure and protect customers in the 
event of bankruptcy. Namely, most states
 require MSBs to abide by net-worth requirements, security 
requirements, and restrictions on permissible investments.  
These regulations are significantly more permissive than the legal regimes governing banks and MMFs. 
MSB net-worth requirement
s vary markedly among different states and are typically far more 
accommodating than bank capital rules. For example, while South Dakota
 requires MSBs to maintain a 
net worth of at least $100,000, federally insured banks ar
e subject to a minimum capital requirement of 
eight percent of their risk-weighted assets.  
Security requirements for MSBs—including surety-bond, letter-of-credit, collateral-deposit, and 
insurance requirements—likewise
 differ between jurisdictions and can be quite low relative to the value 
of a firm’s liabilities. For example, Maine
 requires MSBs to obtain a surety bond, letter of credit, or 
similar security device in an amount of at least $100,000. In contrast, the Federal Deposit Insurance 
Corporation
 insures bank deposits up to $250,000 for each depositor.  
MSB
 investment restrictions range from rules that approximate MMF regulation to more lenient 
requirements that permit investments in public equities, subject to certain concentration limits. Twelve 
states impose
 no restrictions on an MSB’s investments.

Stablecoin issuers are also subject to certain federal regulations. Federal law
 requires money-transmitting 
businesses to register with the Treasury Department and comply with
 anti-money laundering requirements 
in the Bank Secrecy Act. The Commodity Futures Trading Commission also has
 authority to police fraud 
and manipulation in the cash markets for stablecoins, which the agency deployed in 2021 when it
 settled 
allegations that Tether had misrepresented the nature of the assets backing its stablecoin.  
Other aspects of the federal regulatory framework governing stablecoins remain unsettled. In particular, 
commentators have explored whether stablecoins might also fall within the purview of federal securities 
law or banking law. The following subsections discuss each in turn.  
Securities Law 
The Securities and Exchange Commission (SEC) has not, to date, taken action to regulate stablecoin 
issuers. SEC Chairman Gary Gensler has
 said, however, that some stablecoins may qualify as “securities” 
under federal law—a designation that would subject issuers to
 registration and
 reporting requirements. 
Chairman Gensler has
 not elaborated on the details of this assessment, but stablecoins would qualify as 
securities under existing law if they represent “investment contracts.” In addition, stablecoins 
may qualify 
as securities if they represent “notes.” Each category has its own legal test.  
Howey and Reves 
To determine whether an instrument is an 
investment contract, courts employ
 the four-part Howey test, 
which provides that an agreement falls within that category if it involves:  
1.  an investment of money;  
2.  in a common enterprise;  
3.  with an expectation of profit;  
4.  derived from the efforts of others. 
By contrast
, the Reves test dictates whether a 
note—a promise to pay a specified sum—is a security. 
Under 
Reves, all notes are presumptively securities. However, that presumption is rebuttable in two ways. 
First, the seller of a note can establish that a note bears a “family resemblance” to one of the constituents 
of a
 judicially created list of notes that are not securities. In determining whether a note bears a family 
resemblance to a category on that list, courts evaluate:   
1.  
The motivations of the buyer and seller. If the seller offers the note to finance a 
business and the buyer is motivated primarily by an expectation of profit, the note is 
likely to be a security. By contrast, if the note is exchanged to facilitate the purchase and 
sale of a consumer good, the note is less likely to be a security.  
2.  
The plan of distribution. If a note is commonly traded for speculation or investment, it 
is more likely to be a security. If it is not frequently traded, it is less likely to be a 
security.  
3.  
The reasonable expectations of the investing public. If the public reasonably believes 
that a note is a security, courts may deem the note a security even when the economic 
circumstances might suggest otherwise.  
4.  
Risk-reducing factors. If some other factor—like an alternative regulatory scheme, 
collateral, or insurance—reduces the risk of a note in such a way as to make the 
application of the securities laws unnecessary, the note is less likely to be a security.  
Second, if a note is not sufficiently similar to an item on the relevant list, a court
 must decide whether to 
add another category to the list by examining the four factors discussed above. (Some lower courts treat 
  
Congressional Research Service 
5 
Reves as involving this two-step process, while
 others have collapsed the two steps into a single inquiry 
analyzing the four factors.)  
Applying the Doctrine 
Both the 
Howey and 
Reves tests are fact-intensive. As a result, the details surrounding specific stablecoin 
offerings may prove decisive under either inquiry. There is also some ambiguity as to when the tests 
apply. The Supreme Court has applied the 
Howey test to evaluate
 agreements that appear to be notes, 
leading some
 commentators t
o wonder whether the standards are mutually exclusive. Accordingly, it is 
uncertain whether a court would determine that a given stablecoin is (1) a note governed only by the 
Reves test, (2) a note governed by both the 
Reves and 
Howey tests, or (3) another type of instrument 
governed only by the 
Howey test.  
Other difficulties lurk behind that threshold question. 
Howey and 
Reves both evaluate whether the buyer 
of an instrument is motivated primarily by an expectation of profits. (Under 
Howey, such expectations are 
necessary for an instrument to qualify as an investment contract. By contrast, 
Reves makes profit 
expectations one element of a multi-part balancing test.)  
This factor arguably cuts against the notion that stablecoins are securities. Stablecoins ordinarily
 do not 
pay interest. They are also designed with the explicit goal of maintaining a stable value, making it 
unlikely that the prospect of capital appreciation is a key factor motivating most stablecoin purchases. The 
SEC has issued guidance to similar effect. The agency’s 2019
 Framework for “Investment Contract” 
Analysis of Digital Assets explains that a cryptocurrency is less likely to be a security under 
Howey if its 
design “provides that its value will remain constant.”  
Even so, some commentators have proposed theories to support the proposition that stablecoin purchasers 
may be motivated by profits for purposes of the 
Howey and 
Reves tests. In brief, the arguments appeal to 
the role that stablecoins play i
n facilitating cryptocurrency speculation and the fact that some stablecoins 
have
 traded above par during crypto-market turmoil. This issue remains unsettled.  
Another wrinkle involves 
Reves’ emphasis on risk-reducing factors—in particular, the relevance of an 
alternative regulatory scheme that would render the securities laws unnecessary. The classic example is 
banking regulation: the Supreme Court ha
s held that bank-issued certificates of deposit are not securities 
based in part on the comprehensiveness of federal banking law. The Court has al
so concluded that 
interests in federally regulated pension plans do not qualify as securities based on the separate protections 
afforded by the Employee Retirement Income Security Act. 
This element of the 
Reves test suggests that a given stablecoin’s status under the securities laws may 
hinge in part on its current regulatory treatment. The exact contours of this inquiry are not entirely clear, 
however. Lower courts have not elaborated on the precise level of protection that a regulatory scheme 
must offer to render the securities laws unnecessary.  
Applying this 
Reves factor to stablecoins is thus difficult. As discussed, state laws governing trust 
companies and MSBs offer stablecoin investors 
some protection against reckless or unscrupulous 
operators. However, that protection is typically less robust than the assurances offered by federal banking 
law. Accordingly, if the SEC pursues stablecoin issuers under 
Reves, the sufficiency of extant state 
regulation may be a key disputed issue.   
Banking Law  
Stablecoins may also implicate federal banking law.
 Section 21(a)(2) of the Glass-Steagall Act makes it 
unlawful for any entity to engage in the business of receiving “deposits” subject to repayment upon 
request, unless the entity falls within one of three categories.   
  
Congressional Research Service 
6 
  
First, an institution can accept “deposits” if it is “
authorized” to do so by federal or state 
law and is subject to examination and regulation. 
  
Second, an institution can accept “deposits” if it is “
permitted” to do so by federal or 
state law and is subject to examination and regulation.  
  
Third, an institution can accept “deposits” if it submits to periodic examination by a state 
banking authority and publishes the same types of periodic reports that the relevant state 
laws require of banks.  
Section 21(a)(2)’
s legislative history indicates that it was intended to prohibit “unregulated private 
banking so far as practicable.” The limited case law applying the provision
 suggests that an entity accepts 
“deposits” when it takes custody of a client’s money subject to repayment upon demand. Persons who 
accept deposits but do not fall within the exempted categories are subject to criminal sanctions, including 
fines and imprisonment of up to five years.  
Stablecoin issuers arguably accept Glass-Steagall “deposits” insofar as they promise to redeem their coins 
at par upon request. 
A November 2021 report from the President’s Working Group on Financial Markets 
gestures toward this possibility, noting that the Department of Justice (DOJ) “may consider whether or 
how section 21(a)(2) of the Glass-Steagall Act may apply to certain stablecoin arrangements.”  
The DOJ has confronted related issues in the past. In 1979, the head of the Department’s Criminal 
Division
 concluded that MMFs do 
not accept “deposits” within the meaning of the Glass-Steagall Act 
because MMF investors are owners rather than creditors of their funds.  
The same may not be true of some stablecoin holders, however. The DOJ based its analysis of MMFs on 
the premise that MMF investors are exposed to fluctuations in a fund’s value. While similar reasoning 
might apply to stablecoins that are formally structured as pro rata interests in a pool of reserve assets, an 
issuer’s promises or suggestions that investors can redeem their coins at par may result in a different 
conclusion. In the latter fact patterns, stablecoin investors are arguably more akin to creditors than 
owners, which could bring a stablecoin issuer within Glass-Steagall’s remit.  
If a stablecoin issuer indeed accepts Glass-Steagall “deposits,” it would need to fall within one of the 
three exemptions outlined above to avoid running afoul of the statute’s prohibition. Whether particular 
stablecoin providers qualify for those exemptions would turn on the nature of their existing regulatory 
supervision. Some observers have
 encouraged federal authorities to clarify the scope of Glass-Steagall’s 
exemptions to provide the industry with greater legal certainty.
