Peningamagnsframboð, often translated as money supply, refers to the total amount of monetary assets available in an economy at a specific time. This includes currency in circulation, demand deposits, and other liquid assets. Central banks play a crucial role in managing the money supply through various monetary policy tools.

There are different measures of money supply, commonly denoted by M0, M1, M2, and M3, each encompassing a broader range of financial instruments. M0 typically includes physical currency and central bank reserves. M1 expands this to include demand deposits, which are funds held in checking accounts. M2 further includes savings accounts, money market securities, and small time deposits. M3, the broadest measure, incorporates larger time deposits and institutional money market funds.

The level of money supply is a key indicator of economic activity and inflation. An excessive increase in the money supply without a corresponding growth in the production of goods and services can lead to inflation, a general increase in prices and a decrease in the purchasing power of money. Conversely, a contraction in the money supply can lead to deflation, a decrease in general price levels, which can also have negative economic consequences.

Central banks adjust the money supply to achieve macroeconomic goals such as price stability, full employment, and sustainable economic growth. Tools used include setting interest rates, open market operations (buying or selling government securities), and reserve requirements for banks. Understanding the dynamics of money supply is fundamental to comprehending monetary policy and its impact on the economy.
