Inflation-Protected debt: The hedge Indian retail investors need

If you're over 30, chances are every third conversation you have eventually turned to portfolio performance. Especially in recent months, these dialogues have become increasingly animated. Picture this: Rahul, 37, boasts about having exited equities just in time, locking in a commendable 12% annualised return.

His older friend Vineet, more risk-averse, responds with equal pride about his decade-long loyalty to fixed deposits (FDs), earning a steady 7%—free of market-induced stress. The conversation inevitably veers into a lament about taxation eating into their hard-earned gains.

But taxes aren't the only silent force eroding investment returns. The more insidious thief is inflation.


Over the past decade, India’s average annual inflation rate has hovered at 5.2%. That means Rahul’s impressive 12% nominal return translates into a real return of just 6.8%. Vineet, meanwhile, eked out a mere 1.8% in real terms. The inflation-adjusted figures across asset classes tell a sobering story:

Whether it's equities, bonds, real estate—or even cryptocurrency—inflation is a constant headwind, quietly diluting purchasing power. While inflation has moderated in recent quarters, India’s structural realities—a vast population, a constrained capital base, and significant reliance on imported commodities like crude oil—mean that inflationary pressures are likely to persist. Add to this a robust domestic consumption story and potential global supply chain disruptions, including the Trump administration’s renewed protectionist stance, and the outlook for price stability becomes murkier.

Against this backdrop, inflation protection is no longer a luxury; it is a necessity.

There are two primary mechanisms by which investors can shield themselves—at least partially—from inflation. The first is through indexation benefits on capital gains taxation. This approach adjusts the acquisition cost of assets by inflation, thereby reducing the taxable capital gain. It has traditionally provided a much-needed cushion for long-term holders of real estate and debt mutual funds. However, recent Union Budgets (2023 and 2024) have disappointingly rolled back these benefits, leaving investors more exposed than before.

A more direct and effective shield comes in the form of Inflation-Protected Securities (IPS). These instruments offer a real rate of return by indexing the principal or interest—or both—to inflation. For instance, consider a bond with a real yield of 5%. If inflation is 4% for the year, the actual payout would be approximately 9.2.

This is achieved by first adjusting the principal upward by the inflation rate and then applying the real rate to this inflated principal. For example, The principal, say of INR 1,000, is adjusted for inflation at 4% resulting in INR 1,040 and the 5% interest is then applied to this adjusted principal. Thus, not only is purchasing power preserved, but it also grows predictably.

The United States has long led the way in this arena, with Treasury Inflation-Protected Securities (TIPS) first issued in 1997 and still actively marketed, with the latest tranche offered as recently as March 20, 2025. The success of TIPS has spurred a thriving ecosystem, including corporate IPS issuance and the development of TIPS-focused bond funds and ETFs accessible to both institutional and retail investors.

India’s experiment with inflation-linked instruments has been far more modest. The Reserve Bank of India (RBI) introduced its first 10-year Inflation-Indexed Bonds (IIBs) in 2013 to strong demand. Yet, despite keeping the option open in subsequent years, the central bank has refrained from further issuances. This is a missed opportunity.

Today’s macroeconomic environment makes a compelling case for the revival—and expansion—of inflation-protected instruments in India. Beyond sovereign bonds, large Indian corporates should also consider issuing IPS to tap into a rising tide of fixed-income investors hungry for both yield and safety. Offering a spectrum of tenures—especially shorter-duration instruments—could galvanize the growing retail participation in bonds.

As India continues to evolve as a consumption-driven economy, the need to preserve real returns becomes paramount. It’s time inflation protection moved from being a niche tool for the sophisticated few to a staple in the investment toolkit of every Indian retail investor.
