Treasuries and Repo in the Time of COVID-19 
July 20, 2020 
Background: Three Roles for Treasuries 
The U.S. Treasury issues debt securities—known as Treasuries—that play three critical roles in the 
economy: funding the government, supplying safe assets, and anchoring liquidity flows in financial 
markets. This Insight examines how the coronavirus pandemic has affected al  three roles.  
Treasuries primarily serve as a means of government finance. The U.S. Treasury sel s securities to obtain 
cash to fund government operations when revenues fal  short of outlays. The Treasury issues bil s, 
maturing within a year, to respond to short-term financing needs. Treasury notes, with maturities up to 10 
years, and bonds, with longer maturities, help the government hedge against the risk of rising interest 
rates. Most Treasuries first sel  in scheduled auctions and then trade in secondary markets. 
Investors hand over cash to purchase Treasuries to obtain assets essential y free of default risk that serve 
as a store of value as wel  as a safe haven against severe market or other unforeseen risks. Interest rate 
changes affect the price of Treasuries. Longer-term Treasuries general y carry higher yields to induce 
investors to lock up funds for longer times. The yield curve—a plot of Treasuries’ yields ordered by their 
maturities—therefore usual y slopes upwards. A downward sloping, or inverted yield curve can signal an 
impending economic slowdown. 
Treasuries anchor liquidity flows in financial markets largely through repurchase agreements, or repos. A 
repo provides a common means of secured lending, often within the nexus of financing arrangements 
involving nonbank financial institutions sometimes cal ed the shadow banking system. Most repo trades 
use Treasury securities for collateral, intertwining repos and markets for Treasuries. Repos al ow asset 
holders to obtain extra revenues on otherwise idle assets. Most U.S. repo lending is overnight, although 
some repos continue on a rolling or open basis. 
For instance, a hedge fund may sel  $100 mil ion  in Treasuries to a bank for a day in return for $98 
mil ion  in cash to fund its operations. The next morning, the hedge fund repurchases the Treasuries, 
returning the cash and an interest charge to the bank. That $2 mil ion difference—the haircut—helps 
protect the bank from credit and transactions risks. Haircuts for other types of assets are general y higher. 
Asset holders and borrowers might also transact a repo through a clearing bank, cal ed a triparty repo. 
Hedge funds use repos for leverage by taking short positions on Treasuries—that is, lending borrowed 
Treasuries.

Dramatic Moves in Financial Markets in March 2020 
Financial markets reacted sharply once the World Health Organization declared Coronavirus Disease 
2019 (COVID-19) a global  pandemic on March 11, 2020. In the following week, some market indices had 
multiple  historic fal s in value, a market adjustment far more sudden than the onset of the financial crisis 
of 2007-2009. In Treasuries markets during March 2020, yields on Treasury securities of al  maturities 
fel  (Figure 1), some reaching historic lows. The 10-year bond yield dropped below 1% for the first time 
and the 30-year bond had a yield of 1.27%—the one-month T-bil  yield a month earlier.

Sudden inflows into money market funds holding government securities and withdrawals from other 
money market funds mirrored the rush into Treasuries (Figure 2).

What Caused Those Market Movements? 
Within the general uncertainty of the COVID-19 pandemic, two factors helped drive these movements. 
First, many firms faced severe revenue drop-offs, sparking demand for cash and credit while depressing 
risky assets’ prices and raising safe assets’ prices, especial y Treasuries. Post-2007-2009 financial crisis 
bank leverage limits were eased to bolster the supply of credit. Surging demand for cash also drove 
unusual patterns in Treasury prices, which vary inversely with yields. Asset prices that tended to trend 
together, such as Treasuries and stock indices, diverged. Even 10-year Treasury yields and mortgage rates, 
which usual y move in tandem, diverged, indicating extraordinary financial stresses. Massive Federal 
Reserve support and COVID-19 response efforts funded by Congress helped ease divergences in late 
April 2020. 
Second, repo lending supports the leveraging strategies of hedge funds and similar entities. One analysis 
noted “any sustained disruption in this market, with daily turnover in the US market of about $1 tril ion, 
could quickly ripple through the financial system.” COVID-19 stresses prompted deleveraging—a 
pullback in the borrowing of safer assets and curtailed demand for risky assets. A hedge fund using a 
leveraged funding strategy could exchange Treasuries with a bank to borrow cash. The hedge fund would 
then be short on Treasuries—holding a negative position in them—and long on assets purchased with 
borrowed cash. Financial theory suggests investors facing higher market volatility reduce short positions 
in Treasuries and sel  some risky assets. As other firms do likewise, prices of riskier assets fal , further 
straining leveraged positions. Avoiding  such fire-sale dynamics appeared to spur some Federal Reserve 
responses to enhance market liquidity. The shadow banking sector faced more pressure than the formal 
banking sector, which bolstered capital reserves following the 2007-2009 financial crisis. 
Historic Increase in Treasury Supply Ahead 
Congress enacted fiscal responses to the pandemic,  including  the CARES Act (P.L. 116-136), 
scored as costing  about $1.7 tril ion,  mostly  for FY2020  and FY2021. Funding  those outlays 
implies  an unprecedented increase in the issuance of Treasuries. Lowered yields  shown in Figure 
1 reflect strong  demand for Treasuries. Market pricing  indicates  low interest rates wil   persist, 
lessening  debt service costs. Nevertheless, fiscal chal enges  loom.  Slower  economic  activity 
reduces federal revenues and expanding  public  debt underlines  preexisting  concerns about the 
federal fiscal  trajectory. Other long-term  fiscal  chal enges,  such as the Baby Boomer retirement 
and climate  change, remain. Many economists,  however,  regard responding  to COVID-19 as 
more important  than restraining  federal debt at present.
