What's Happening?
On March 15, 2020, the Federal Reserve announced it would cut reserve requirement ratios for all depository institutions to zero percent, effective March 26, 2020. This action eliminated mandatory reserve requirements, freeing an estimated $200 billion
of reserves that banks previously needed to hold. Prior to this change, banks were required to hold a set fraction of their deposits as reserves, either as vault cash or balances at the Federal Reserve. This system, governed by Regulation D, had a three-tier structure with varying ratios depending on the amount of net transaction accounts. The stated logic behind the elimination was to enable banks to lend more freely during the economic disruption caused by the COVID-19 pandemic, converting what was considered 'dead weight' into lendable funds.
Why It's Important?
The elimination of reserve requirements marks a significant shift in U.S. monetary policy, fundamentally altering how the Federal Reserve influences the money supply and banking operations. Historically, reserve requirements were considered a key tool for controlling money creation. However, the Fed's framework had already evolved since 2008 to one of 'ample reserves,' where it pays interest on reserve balances. In this environment, a mandatory reserve ratio became largely non-binding, as banks voluntarily held trillions in excess reserves. The change removed a 'competitive distortion' for U.S. banks compared to those in jurisdictions without such rules. This move emphasizes that monetary policy now primarily works through interest rates paid on reserves and the supply of reserves, rather than through a mandatory ratio. It also highlights that bank lending is now constrained more by capital and liquidity rules, risk appetite, and credit demand, rather than by the availability of reserves.
What's Next?
With reserve requirements at zero, the Federal Reserve will continue to steer lending conditions primarily through interest rates, specifically the interest on reserve balances (IORB) rate, and by managing the supply of reserves through open market operations and quantitative tightening. Banks will continue to hold reserves voluntarily because they earn interest, settle payments, and satisfy liquidity rules. The focus of bank regulation remains on capital requirements, such as Basel-style rules that mandate equity and loss-absorbing debt, and liquidity requirements, like the Liquidity Coverage Ratio (LCR), which ensures banks hold enough high-quality liquid assets to withstand stressed outflows. While the U.S. has moved away from reserve requirements, many other countries, including China and various emerging markets, still actively use them as policy tools, often for countercyclical management of credit cycles.
Beyond the Headlines
The elimination of reserve requirements challenges long-held textbook theories about the money multiplier and how banks create money. The modern view, supported by the Fed's actions, suggests that money creation is 'loans-first, reserves-later,' meaning banks lend when there is creditworthy demand and then obtain any necessary reserves. This shift has profound implications for understanding the banking system and monetary policy. It also underscores that the safety of deposits now primarily relies on FDIC insurance, bank capital buffers, and supervision, rather than a mandatory reserve ratio. The debate over whether reserve requirements should return, particularly after banking scares, continues, with critics arguing that modern failures are liquidity and unrealized-loss issues that a reserve ratio would not prevent. This ongoing discussion reflects a deeper re-evaluation of the tools central banks use to maintain financial stability and manage economic cycles.
