Key idea

Bonds can lose value in the short run when interest rates rise. Inflation-linked bonds are designed to protect your purchasing power better than regular (nominal) bonds, but they come with their own trade-offs.

Nominal vs inflation-linked: what’s different?

• Nominal bonds pay a fixed coupon and return a fixed principal at maturity (in “today’s euros”). Your real (inflation-adjusted) return depends on future inflation.
• Inflation-linked bonds adjust the principal (and usually coupons) with inflation. In simple terms: they aim to pay you back in “real euros”.

When inflation-linked bonds tend to help

• When inflation surprises to the upside (higher than markets expected).
• When you want a partial hedge against unexpected inflation (not a guarantee against all inflation scenarios).

Common misunderstandings (ETF investor edition)

• “Inflation-linked means no drawdowns.” False. These bonds are still sensitive to interest rates (real yields). They can drop when real yields rise.
• “They always beat nominal bonds during inflation.” Not always. If inflation was already priced in, nominal bonds can perform similarly or better.
• “It’s a perfect hedge for my whole portfolio.” No. It mainly targets inflation risk in the bond sleeve, not equity risk.

Simple rule-of-thumb allocation

If you use bonds to stabilize your portfolio, inflation-linked bonds can be a satellite next to your core bond ETF. Many investors keep them as a minority share of the bond allocation, especially when inflation uncertainty feels meaningful.

Bottom line

Nominal bonds hedge growth/rate shocks better; inflation-linked bonds hedge unexpected inflation better. A mix can make your bond sleeve more robust, but neither is a magic shield.
