Fractional Reserve Banking - Money Supplies Around The World

Money Supplies Around The World

Fractional-reserve banking determines the relationship between the amount of "central bank money" in the official money supply statistics and the total money supply. Most of the money in these systems is "commercial bank money". Fractional-reserve banking allows the creation of commercial bank money, which increases the money supply through the deposit creation multiplier. The issue of money through the banking system is a mechanism of monetary transmission, which a central bank can influence indirectly by raising or lowering interest rates (although banking regulations may also be adjusted to influence the money supply, depending on the circumstances).

This table gives an outline of the makeup of money supplies worldwide. Most of the money in any given money supply consists of commercial bank money. The value of commercial bank money is based on the fact that it can be exchanged freely at a bank for central bank money.

The actual increase in the money supply through this process may be lower, as (at each step) banks may choose to hold reserves in excess of the statutory minimum, borrowers may let some funds sit idle, and some members of the public may choose to hold cash, and there also may be delays or frictions in the lending process. Government regulations may also be used to limit the money creation process by preventing banks from giving out loans even though the reserve requirements have been fulfilled.
