What are Inflation-Indexed Bonds & How They Work

Inflation-indexed bonds (IIB) are a type of government securities that aims to protect investors from the surge in prices within the economy. In this case, bonds link their value to the rate of inflation, thus attempting to maintain the real purchasing power of money. In an era where inflation is accelerating, this has major implications because inflation-indexed bonds tend to lock in stability during times when the cost of goods and services rises.

Inflation-indexed bonds work by revising both the principal amount and interest payments according to inflation. This ensures that the investor’s returns stay aligned with real economic conditions rather than losing value over time. Their structure generally makes them a suitable option for anyone seeking safety from inflation-driven losses, depending on individual risk appetite.

3. Interest Calculation: The inflation-adjusted principal, not the initial sum, will be used to calculate interest.  
4. Interest Payout: Based on the revised principal, investors receive their interest payments, which are typically made every six months.  
5. Maturity: The investor is paid back either the original principal or the inflation-adjusted principle, whichever is higher.
