Over the last couple of decades, reserve requirements all but vanished as a means of bank regulation and monetary control. But now a new variation on reserve requirements is being introduced through the capital controls of the Basel Accords.
Canada, the UK, Sweden, Australia, New Zealand, and Hong Kong have all abolished traditional reserve requirements. In many other countries, reserve requirements have become a dead letter. In the U.S., for instance, the Fed under Alan Greenspan reduced all reserve requirements to zero except for transactions deposits (checking accounts), while permitting banks to evade reserve requirements on transactions balances by using sophisticated computer software to regularly “sweep” those balances into money market deposit accounts, which have no reserve requirement. In 2011 Congress went a step further by allowing the Fed to eliminate all reserve requirements if it so desired. The Eurozone, for its part, began with a reserve requirement of only 2 percent, which was reduced to 1 percent in January 1999.
There were good reasons for this deregulatory trend. Economists consider reserve requirements an implicit tax on banks, requiring them to hold non-interest earning assets, while central banks considered changes in such requirements too blunt an instrument for monetary control. The Fed discovered the latter shortcoming when, in the midst of the Great Depression, having just gained control over the reserve requirements of national banks, it doubled them, contributing to recession of 1937.
Ostensibly designed to keep banks more liquid, reserve requirements can prevent them from drawing on their liquidity when it is most needed. As Armen A. Alchian and William R. Allen point out in University Economics (1964): “To rely upon a reserve requirement for the meeting of cash-withdrawal demands of banks’ customers is analogous to trying to protect a community from fire by requiring that a large water tank be kept full at all times: the water is useless in case of emergency if it cannot be drawn from the tank.”
