Inflation-Protected Income: How to Secure It
Key takeaways
- Nominal return without accounting for inflation is misleading — only real return matters.
- Equities have historically provided inflation protection over the long term, but not in the short term.
- Inflation-linked bonds offer direct protection, at the cost of a lower yield.
- Real assets can help keep returns in line with inflation, but they are illiquid.
- A fixed nominal income gradually erodes in real terms — without indexation it loses purchasing power every year.
Inflation is the silent thief of retirement income — every percent per year erodes part of purchasing power without the person noticing immediately. For a retiree with a 25–30 year horizon, this is a key risk.
Why Nominal Income Is Not Enough
Imagine an income of CZK 50,000 per month. At an average inflation rate of 3% per year, after 20 years its real value will correspond to roughly CZK 27,000 in today's prices. In other words: the standard of living will nearly halve over two decades, even though the number on the statement remains the same.
Tools for Protecting Purchasing Power
- Equities (global indices) — historically provided returns above inflation. Volatile in the short term, but a strong protection of purchasing power over a 20+ year horizon.
- Inflation-linked bonds — for example US TIPS or their European equivalents. The principal grows with inflation, but the yield is lower than that of standard bonds. Suitable as a stabilizing component.
- Real assets — real estate, commodities. Illiquid, administratively more demanding, but historically correlated with inflation.
A Dynamic Distribution Strategy
Instead of a fixed nominal amount, consider indexing distributions — increasing them each year by the inflation rate, or by a fixed percentage. This depletes the portfolio faster, however, so you must start from a lower base withdrawal rate. Alternatively, some retirees adjust flexibly: taking more in good years and less in bad ones.
Real Return Is the Only Metric That Counts
A portfolio return of 7% with 4% inflation gives a real return of only 3%. That is why the foundation of every projection is the real, not the nominal, rate of return. Our projection calculator takes this into account. How to plan the transition into the distribution phase is covered in the article on transitioning from accumulation.
FAQ
Do equities protect against inflation?
Over the long term, yes — companies can raise prices and pass inflation on to customers, which flows through to earnings and share prices. In the short term, equities respond unpredictably. For a retiree with a 20+ year horizon, equities are the core component of purchasing power protection.
What are TIPS?
Treasury Inflation-Protected Securities — US government bonds whose principal is linked to the consumer price index. You protect the nominal value of your investment from inflation, but the yield is lower than that of standard bonds.
Is a fixed or variable income better?
A fixed nominal income is psychologically comfortable, but loses real value over time. A variable income (indexed or flexible) better protects purchasing power, but requires discipline and equanimity when payments are lower in worse years.
