Economics 28
When a central bank acts as a lender of last resort, it makes short-term loans available in situations of severe financial panic or stress. The failure of a single bank can be treated like any other business failure. Yet if many banks fail, it can reduce aggregate demand in a way that can bring on or deepen a recession. The combination of deposit insurance, bank supervision, and lender of last resort policies help to prevent weaknesses in the banking system from causing recessions.

expansionary monetary policy
a monetary policy that increases the supply of money and the quantity of loans
contractionary monetary policy
a monetary policy that reduces the supply of money and loans
inflation targeting
a rule that the central bank is required to focus only on keeping inflation low
lender of last resort
an institution that provides short-term emergency loans in conditions of financial crisis
deposit insurance
an insurance system that makes sure depositors in a bank do not lose their money, even if the bank goes bankrupt
countercyclical
moving in the opposite direction of the business cycle of economic downturns and upswings
tight monetary policy
see contractionary monetary policy
loose monetary policy
see expansionary monetary policy
federal funds rate
the interest rate at which one bank lends funds to another bank overnight
reserve requirement
the percentage amount of its total deposits that a bank is legally obligated to to either hold as cash in their vault or deposit with the central bank
quantitative easing (QE)
the purchase of long term government and private mortgage-backed securities by central banks to make credit available in hopes of stimulating aggregate demand
velocity
the speed with which money circulates through the economy; calculated as the nominal GDP divided by the money supply
bank run
when depositors race to the bank to withdraw their deposits for fear that otherwise they would be lost
central bank
institution which conducts a nation's monetary policy and regulates its banking system
basic quantity equation of money
money supply × velocity = nominal GDP
excess reserves
reserves banks hold that exceed the legally mandated limit
open market operations
the central bank selling or buying Treasury bonds to influence the quantity of money and the level of interest rates
discount rate
the interest rate charged by the central bank on the loans that it gives to other commercial banks
A bank run occurs when there are rumors (possibly true, possibly false) that a bank is at financial risk of having negative net worth. As a result, depositors rush to the bank to withdraw their money and put it someplace safer. Even false rumors, if they cause a bank run, can force a healthy bank to lose its deposits and be forced to close. Deposit insurance guarantees bank depositors that, even if the bank has negative net worth, their deposits will be protected. In the United States, the Federal Deposit Insurance Corporation (FDIC) collects deposit insurance premiums from banks and guarantees bank deposits up to $250,000. Bank supervision involves inspecting the balance sheets of banks to make sure that they have positive net worth and that their assets are not too risky. In the United States, the Office of the Comptroller of the Currency (OCC) is responsible for supervising banks and inspecting savings and loans and the National Credit Union Administration (NCUA) is responsible for inspecting credit unions. The FDIC and the Federal Reserve also play a role in bank supervision.

A central bank has three traditional tools to conduct monetary policy: open market operations, which involves buying and selling government bonds with banks; reserve requirements, which determine what level of reserves a bank is legally required to hold; and discount rates, which is the interest rate charged by the central bank on the loans that it gives to other commercial banks. The most commonly used tool is open market operations.

An expansionary (or loose) monetary policy raises the quantity of money and credit above what it otherwise would have been and reduces interest rates, boosting aggregate demand, and thus countering recession. A contractionary monetary policy, also called a tight monetary policy, reduces the quantity of money and credit below what it otherwise would have been and raises interest rates, seeking to hold down inflation. During the 2008-2009 recession, central banks around the world also used quantitative easing to expand the supply of credit.

Monetary policy is inevitably imprecise, for a number of reasons: (a) the effects occur only after long and variable lags; (b) if banks decide to hold excess reserves, monetary policy cannot force them to lend; and (c) velocity may shift in unpredictable ways. The basic quantity equation of money is MV = PQ, where M is the money supply, V is the velocity of money, P is the price level, and Q is the real output of the economy. Some central banks, like the European Central Bank, practice inflation targeting, which means that the only goal of the central bank is to keep inflation within a low target range. Other central banks, such as the U.S. Federal Reserve, are free to focus on either reducing inflation or stimulating an economy that is in recession, whichever goal seems most important at the time.

The most prominent task of a central bank is to conduct monetary policy, which involves changes to interest rates and credit conditions, affecting the amount of borrowing and spending in an economy. Some prominent central banks around the world include the U.S. Federal Reserve, the European Central Bank, the Bank of Japan, and the Bank of England.
