A persistent and appreciable rise in the general level of price is known as inflation. Inflation occurs when the supply of money in the economy increases faster than the supply of goods and services. This causes the value of money to decrease, which in turn leads to an increase in the prices of goods and services. Inflation can be caused by various factors such as an increase in demand for goods and services, an increase in the cost of production, or a decrease in the supply of goods and services. Inflation reduces the purchasing power of money, which means that consumers can buy fewer goods and services with the same amount of money. It also affects savings and investments, as the real value of money decreases over time due to inflation.
