Inflation refers to the rise in the prices of most goods and services of daily or common use, such as food, clothing, housing, recreation, transport, consumer staples, etc. Inflation measures the average price change in a basket of commodities and services over time. The opposite and rare fall in the price index of this basket of items is called ‘deflation’. Inflation is indicative of the decrease in the purchasing power of a unit of a country’s currency. This is measured in percentage.
