Inflation-Indexed Bonds

Inflation-Indexed Bonds protect investors from inflation by adjusting principal and/or interest payments based on inflation indices, providing real return certainty crucial for long-term investors. Major markets include US TIPS ($1.7 trillion), UK index-linked gilts (£800 billion), and European inflation-linkers (€800 billion). Structure typically involves principal adjustment by Consumer Price Index with coupons paid on inflated principal. For example, a 2% TIPS with $1,000 principal becomes $1,030 principal after 3% inflation, paying $20.60 annual interest. Breakeven inflation rates (nominal yield minus real yield) indicate market inflation expectations – 10-year US breakevens around 2.3% suggest moderate inflation expectations. Benefits include perfect inflation hedge, portfolio diversification, and real liability matching for pension funds. Challenges include taxation of phantom income from principal adjustments, potential deflation floors, and different inflation indices across countries. Recent inflation surge drove strong performance – TIPS returned 6% in 2021 versus -1.5% for nominal Treasuries. Inflation-indexed bonds demonstrate government commitment to protecting purchasing power while providing market-based inflation expectations.
