Inflation-Protected Investing UK: How to Beat Stealth Erosion
Your 'high-rate' savings account is losing the war quietly. The headline interest rate is not the number that matters. The one that does has been negative more years than positive.
Cash real returns 2020-2024
| Year | Easy-access rate | UK inflation | Real return |
|---|---|---|---|
| 2020 | 0.5% | 0.9% | -0.4% |
| 2021 | 0.4% | 2.6% | -2.2% |
| 2022 | 1.5% | 9.1% | -7.6% |
| 2023 | 4.5% | 6.2% | -1.7% |
| 2024 | 4.7% | 2.5% | +2.2% |
Five 'decent' cash years still produced a cumulative real loss of around 9%.
Key takeaways
Cash savings lose purchasing power even at "good" interest rates - 4% interest on 3% inflation is only 1% real return
Index-linked gilts (linkers) are the most direct UK inflation hedge but have significant duration risk and complex tax treatment
A globally diversified equity portfolio has historically beaten inflation by ~5-7% per year over rolling 20-year periods
Property and commodities offer partial inflation protection but with high volatility and concentration risk - rarely the right primary hedge
