What is monetary policy? Definition and meaning

Monetary policy is the main focus of a central bank, it involves regulating the money supply and interest rates. The US Federal Reserve, the Bank of England, the European Central Bank, the Bank of Japan, the Bank of Canada, The Reserve Bank of Australia and other central banks manage monetary policy to control inflation, stabilize their country’s or region’s currency, and make sure the economy is moving in the right direction.

By regulating what effectively is the cost of money, a central bank can affect the amount of money that is spent by businesses and individuals.

Monetary policy aims to maintain stability and confidence

According to the Bank of England, monetary stability means confidence in the currency and stable prices. Stable prices are defined by the inflation target set by the Government, which the central bank seeks to meet through the decisions made – in the case of the Bank of England – by the MPC (Monetary Policy Committee).

Monetary Policy two typesWhen the economy is sluggish central banks tend to go for an expansionist monetary policy. However, if prices start rising too rapidly – if the economy is overheating – they will opt for a contractionary monetary policy.

The Bank of England writes on its website:

“Monetary policy in the UK usually operates through the price at which money is lent – the interest rate. In March 2009 the MPC announced that in addition to setting Bank Rate, it would start to inject money directly into the economy by purchasing financial assets – often known as quantitative easing.”



The US Federal Reserve System (Federal Reserve), America’s central bank, says the term ‘monetary policy’ refers to the actions it takes to influence the availability and cost of money and credit to help promote national economic goals.

The Federal Reserve Act of 1913 gave America’s Central Bank responsibility for setting the country’s monetary policy.

Low interest rates monetary policyDuring a recession, the central bank adopts an expansionist monetary policy, initially by lowering interest rates in the hope that consumers and businesses borrow more, and so spend more, which eventually boosts the economy and creates more jobs.

Three tools of monetary policy

The Federal Reserve, like most other central banks, controls three tools of monetary policy:

Open market operations: this is the responsibility of the Federal Open Market Committee.

The discount rate: responsibility of the Board of Governors of the Federal Reserve System.

The reserve requirements: also the responsibility of the Board of Governors of the Federal Reserve System.



Using these three tools, the US central bank influences the demand for and supply of balances that depository institutions hold at the Federal Reserve Banks, and in this manner alters the federal funds rate.

Changes in the federal funds rate generate a chain of events that affect several short-term interest rates, as well as long-term rates, foreign exchange rates, the amount of money and credits, and ultimately a series of economic variables including the prices of goods and services, output and employment.

The Federal Reserve says the following regarding the Federal Open Market Committee:

“The  Federal  Open  Market  Committee (FOMC) is firmly committed to fulfilling its statutory mandate from the Congress of promoting maximum employment, stable prices, and moderate long-term interest rates.”

“The Committee seeks to explain its monetary policy decisions to the public as clearly as possible.  Such clarity facilitates well-informed decision-making by households and businesses, reduces economic and financial uncertainty, increases the effectiveness of monetary policy, and  enhances transparency and accountability, which are essential in a democratic society.”

In the UK, the Bank of England’s (BoE’s) Monetary Policy Committee (MCP) makes monetary policy decisions, including the setting of interest rates. It sets an interest rate it judges will make sure that the inflation target is met.

The MCP consists of nine members: the Governor; the three Deputy Governors for Markets & Banking, Financial Stability, and Monetary policy; the BoE’s Chief Economist, plus four external members appointed directly by the Chancellor of the Exchequer.

Monetary Economics

Monetary Economics: this is a division of Economics that looks at monetary theory, the effects of monetary variables on the macroeconomic system, the role of the Central Bank, and the conduct of monetary policy.

In the London School of Economics, for example, it may be part of several degree courses, including BSc in Business Mathematics and Economics, BSc in Economics and Economic History, BSc in Mathematics and Economics, BSc in Philosophy Politics and Economics, and BSc in Social Policy and Economics.

Expansionary and contractionary monetary policy

Monetary policy is referred to as being either contractionary or expansionary. A contractionary policy expands the money supply slower than usual, and even sometimes shrinks it.

An expansionary policy, on the other hand, expands the total supply of money in the economy more rapidly than usual.

Traditionally, expansionary policy is used to try and bring down unemployment during a recession by lowering interest rates in the hope that businesses will borrow more and thus expand.

When inflation picks up, a contractionary policy may be used in order to avoid resulting distortions and declining asset values.

Monetary policy is not the same as fiscal policy, which refers to government spending, taxation and borrowing related to government spending.

The Financial Times Lexicon says the following regarding monetary policy:

“The decisions a monetary authority makes to manage the money supply. The tools at its disposal include modifying benchmark interest rates (such as the Fed funds target and the discount rate in the US), conducting money market operations (which influence short-term interest rates), and changing banks’ reserve requirements.”

“Depending on whether the authority wishes to expand money supply, keep it steady or reduce it, monetary policy can be described as accommodative (or loose), neutral or tight.”
