Monetary Policy and Money Market Funds in Europe
As shown in a past Liberty Street Economics post, in the United States, the yields of money market fund (MMF) shares respond to changes in monetary policy rates much more than the rates of bank deposits; in other words, the MMF beta is much higher than the deposit beta. Consistent with this, the size of the U.S. MMF industry fluctuates over the interest rate cycle, expanding during times of monetary policy tightening. In this post, we show that the relationship between the policy rates of the European Central Bank (ECB) and the size of European MMFs investing in euro-denominated securities is ...

Monetary Policy, Investor Flows, and Loan Fund Fragility
We show that monetary policy shocks have a positive effect on flows in bank-loan mutual funds. This relationship, however, is asymmetric: positive shocks cause small inflows, whereas negative shocks cause large outflows. Further, the effect of monetary policy shocks is stronger when short-term rates are higher. Finally, we document that large outflows from loan funds lead to significant declines in loan-level prices in the secondary leveraged loan market. Our results identify a novel channel of monetary policy transmission that not only affects a critical segment of the credit sector, but ...

Tracking Reserve Ampleness in Real Time Using Reserve Demand Elasticity
As central banks shrink their balance sheets to restore price stability and phase out expansionary programs, gauging the ampleness of reserves has become a central topic to policymakers and academics alike. The reason is that the ampleness of reserves informs when to slow and then stop quantitative tightening (QT). The Federal Reserve, for example, implements monetary policy in a regime of ample reserves, whereby the quantity of reserves in the banking system needs to be large enough such that everyday changes in reserves do not cause large variations in short-term rates. The goal is ...

Monetary Policy Transmission and the Size of the Money Market Fund Industry: An Update
The size of the money market fund (MMF) industry co-moves with the monetary policy cycle. In a post published in 2019, we showed that this co-movement is likely due to the stronger response of MMF yields to monetary policy tightening relative to bank deposit rates, combined with MMF shares and bank deposits being close substitutes from an investor’s perspective. In this post, we update the analysis and zoom in to the current monetary policy tightening by the Federal Reserve.

Stablecoins and Crypto Shocks: An Update
Stablecoins are crypto assets whose value is pegged to that of a fiat currency, usually the U.S. dollar. In our first Liberty Street Economics post, we described the rapid growth of stablecoins, the different types of stablecoin arrangements, and the May 2022 run on TerraUSD, the fourth largest stablecoin at the time. In a subsequent post, we estimated the impact of large declines in the price of bitcoin on cumulative net flows into stablecoins and showed the existence of flight-to-safety dynamics similar to those observed in money market mutual funds during periods of stress. In this post, ...

The Optimal Supply of Central Bank Reserves under Uncertainty
This paper provides an analytically tractable theoretical framework to study the optimal supply of central bank reserves when the demand for reserves is uncertain and nonlinear. We fully characterize the optimal supply of central bank reserves and associated market equilibrium. We find that the optimal supply of reserves under uncertainty is greater than that absent uncertainty. With a sufficient degree of uncertainty, it is optimal to supply a level of reserves that is abundant (on the flat portion of the demand curve) absent shocks. The optimal mean spread between the market interest rate ...

Do Low Rates Encourage Yield Seeking by Money Market Funds?
The term “reach for yield” refers to investors’ tendency to buy riskier assets in hopes of securing higher returns. Do low rates on safe assets encourage such yield-seeking behavior, particularly among U.S. prime money market funds (MMFs)? In a forthcoming paper in the Journal of Financial Economics, I develop a model of MMF competition to understand whether competitive pressure leads these funds to reach for yield in a low-rate environment like the current one. I test the model’s predictions on the 2002-08 period and show that, after controlling for changes in risk premia, declines ...

Sophisticated and Unsophisticated Runs
In March 2020, U.S. prime money market funds (MMFs) suffered heavy outflows following the liquidity shock triggered by the COVID-19 crisis. In a previous post, we characterized the run on the prime MMF industry as a whole and the role of the liquidity facility established by the Federal Reserve (the Money Market Mutual Fund Liquidity Facility) in stemming the run. In this post, based on a recent Staff Report, we contrast the behaviors of retail and institutional investors during the run and explain the different reasons behind the run.

Investors’ appetite for money-like assets: the money market fund industry after the 2014 regulatory reform
This paper uses a quasi-natural experiment to estimate the premium investors are willing to pay to hold money-like assets. The 2014 SEC reform of the money market fund (MMF) industry reduced the money-likeness only of prime MMFs, by increasing the information sensitivity of their shares, and left government MMFs unaffected. As a result, investors fled from prime to government MMFs, with total outflows exceeding $1 trillion. By comparing investors’ response to the regulatory change with past episodes of industry dislocation (for example, the 2008 MMF run), we highlight the difference between ...

Runs on Stablecoins
Stablecoins are digital assets whose value is pegged to that of fiat currencies, usually the U.S. dollar, with a typical exchange rate of one dollar per unit. Their market capitalization has grown exponentially over the last couple of years, from $5 billion in 2019 to around $180 billion in 2022. Notwithstanding their name, however, stablecoins can be very unstable: between May 1 and May 16, 2022, there was a run on stablecoins, with their circulation decreasing by 15.58 billion and their market capitalization dropping by $25.63 billion (see charts below.) In this post, we describe the ...
