effects of inflation on money


1. It should be a store of wealth: In a period of inflation, although money retains its nominal value, it loses some of its purchasing power or real value. If people are concerned about money’s loss of value, they will prefer to store their wealth in different assets (e.g. gold, paintings, property or interest-bearing investments) which they do not expect to lose value.

2. It should be a standard for deferred payment: In a period of inflation when the value of money is falling over time, sellers will be reluctant to offer credit or to agree the price for future contracts. Money would then be failing to fulfill its function as a standard for deferred payment.

3. It should be a stable unit of account: As a result of inflation, the relative value of money declines and therefore it loses its function as a stable unit of account.

4. It should be an acceptable means of exchange. When inflation is very high, people might refuse to accept money in exchange. They might instead demand other alternatives such as gold or a foreign currency. provides multiple question and answers and case study on different topics.
