The abandonment of convertibility of money into a commodity since August 15, , when President Richard M. Nixon discontinued converting U. Because money is used in virtually all economic transactions, it has a powerful effect on economic activity. An increase in the supply of money works both through lowering interest rates , which spurs investment , and through putting more money in the hands of consumers, making them feel wealthier, and thus stimulating spending. Business firms respond to increased sales by ordering more raw materials and increasing production. The spread of business activity increases the demand for labor and raises the demand for capital goods. In a buoyant economy, stock market prices rise and firms issue equity and debt.
Measuring Money: Currency, M1, and M2
If the money supply continues to expand, prices begin to rise, especially if output growth reaches capacity limits. As the public begins to expect inflation , lenders insist on higher interest rates to offset an expected decline in purchasing power over the life of their loans.
Why Is the Money Supply Important?
The U. As the chart below shows, it did not. Over the course of U. For that reason, several economists like Milton Friedman pointed to the money supply as a useful indicator of the state of the national economy. Over recent decades, however, that perception of the money supply has changed. In the s, people began to take money out of their low-interest bearing savings accounts and invest it in the booming stock market. As a result, M2 fell, even as the economy grew.

What Is the Money Supply?
Public and private sector analysts monitor changes in the money supply because of the belief that such changes affect the price level of securities, inflationthe exchange rates and the business cycle. The relationship between money and prices has historically been associated with the quantity theory of money. There is strong empirical evidence of a direct relationship between the growth of the money supply and long-term price inflationat least for rapid increases in the amount of money in the economy. For example, a country such as Zimbabwe which saw extremely rapid increases in its money supply also saw extremely rapid increases in prices hyperinflation. This is one reason eupply the reliance on monetary policy as a means of controlling inflation. The nature of this causal chain is the subject of some debate. Some heterodox economists argue that the money supply is endogenous determined by the workings of the economy, not by the central bank and that the sources of inflation must be found in the distributional structure of the economy. In addition, those economists seeing the central bank’s control over the money supply as feeble say that there are two weak links between the growth of the money supply and the inflation rate. First, in the aftermath of a recession, when many resources are underutilized, an increase in the money supply can cause a sustained increase in real monye instead of inflation. Second, if the velocity of money i. Commercial banks play a role in the process of money creation, especially under the fractional-reserve banking system used throughout the world. In this system, money is created whenever a bank gives out a new loan.
