Daily investment at the Federal Reserve’s Overnight Reverse Repo (ON RRP) facility increased from a few billion dollars in March 2021 to more than $2.3 trillion in June 2022 and has stayed above $2 trillion since then. In this post, which is based on a recent staff report, we discuss two channels—a deposit channel and a wholesale short-term debt channel—through which banks’ balance-sheet costs have increased investment by money market mutual funds (MMFs) in the ON RRP facility.
The Federal Reserve employs the discount window (DW) to provide funding to fundamentally solvent but illiquid banks (see the March 30 post “Why Do Central Banks Have Discount Windows?”). Historically, however, there has been a low level of DW use by banks, even when they are faced with severe liquidity shortages, raising the possibility of a stigma attached to DW borrowing. If DW stigma exists, it is likely to inhibit the Fed’s ability to act as lender of last resort and prod banks to turn to more expensive sources of financing when they can least afford it. In this post, we provide evidence that during the recent financial crisis banks were willing to pay higher interest rates in order to avoid going to the DW, a pattern of behavior consistent with stigma.
