Bank reserves are the cash minimums that financial institutions must have on hand in order to meet central bank requirements. This is real paper money that must be kept by the bank in a vault on-site or held in its account at the central bank. Cash reserves requirements are intended to ensure that every bank can meet any large and unexpected demand for withdrawals.

In the U. Bank reserves are primarily an antidote to panic. The Federal Reserve obliges banks to hold a certain amount of cash in reserve so that they never run short and have to refuse a customer's withdrawal, possibly triggering a bank run. A central bank may also use bank reserve levels as a tool in monetary policy. It can lower the reserve requirement so that banks are free to make a number of new loans and increase economic activity.

Or it can require that the banks increase their reserves to slow down economic growth. In recent years, the U. Federal Reserve and the central banks of other developed economies have turned to other tactics such as quantitative easing QE in order to achieve the same goals. The central banks in emerging nations such as China continue to rely on raising or lowering bank reserve levels to cool down or heat up their economies.

The Federal Reserve cut the cash reserve minimum to zero percent effective March 26, Bank reserves are termed either required reserves or excess reserves. The required reserve is the minimum cash the bank can keep on hand.

The excess reserve is any cash over the required minimum that the bank is holding in its vault rather than lending out to businesses and consumers. Banks have little incentive to maintain excess reserves because cash earns no return and may even lose value over time due to inflation.

Thus, banks normally minimize their excess reserves, lending out the money to clients rather than holding it in their vaults. Still, bank reserves decrease during periods of economic expansion and increase during recessions. In good times, businesses and consumers borrow more and spend more. During recessions, they can't or won't take on additional debt.

In downtimes, the banks may also toughen their lending requirements to avoid defaults. Despite the determined efforts of Alexander Hamilton, among others, the United States did not have a national banking system for more than a couple of short periods of time until , when the Federal Reserve System was created.

By , the country at least had a national currency and a national bank chartering system. Until then, banks were chartered and regulated by states, with varying results.

Bank collapses and "runs" on banks were common until a full-blown financial panic in led to calls for reform. The Federal Reserve System was created to oversee the nation's money supply. Its role was significantly expanded in when, during a period of double-digit inflation, Congress defined price stability as a national policy goal and established the Federal Open Market Committee FOMC within the Fed to carry it out.

The required bank reserve follows a formula set by Federal Reserve Board regulations. The formula is based on the total amount deposited in the bank's net transaction accounts. The figure includes demand deposits, automatic transfer accounts, and share draft accounts. By Paul J. Davies Close Paul J. Davies Biography PaulJDavies paul. To Read the Full Story.
