What is Inflation?
Inflation is the rate at which the general price level of goods and services rises over time — and equivalently, the rate at which the purchasing power of a unit of currency falls. If inflation is 6%, a basket of goods that costs ₹100 today will cost about ₹106 next year. For long-term financial planners, inflation is the silent adversary: it erodes the real value of cash, salaries, pensions, and fixed-return investments while leaving nominal numbers unchanged.
The measurement varies by country. India uses Consumer Price Index (CPI Combined) released by MoSPI and Wholesale Price Index (WPI) by DPIIT; the RBI targets 4% headline CPI with a ±2% band under its flexible inflation targeting mandate. Over 30 years, a 6% inflation rate means prices multiply 5.7× — a ₹50,000/month lifestyle today needs roughly ₹2,87,000/month at that future point just to stay flat. Historical long-run equity returns (~12%) beat inflation comfortably; bank FDs (~6–7%) barely keep pace.
Central banks respond to persistent high inflation by raising policy rates (repo rate in India), which feeds into home-loan EMIs and bond yields. Budget 2025 kept the inflation-indexation benefit only for select legacy assets post 23 July 2024.
