Inflation is the quietest wealth destroyer there is. It doesn't make headlines the way a stock market crash does. There's no dramatic chart, no panic on the evening news, no moment where you log into your account and see a big red minus sign. Instead, it works slowly, invisibly, year after year, silently eroding what your money can buy. At 3% inflation, your purchasing power halves in 24 years. At 5%, it halves in 14. At the 11.1% peak we hit in October 2022, it would halve in about 6½ years.
Inflation is not a theoretical concern. It's the single most reliable way to get poorer without noticing. And most people — including, for a long time, me — do almost nothing about it.
I want to walk through exactly what I do to protect my money from inflation. Not economic theory. Not a lecture on monetary policy. Just the practical, actionable steps I take with my own money — the investments I hold, the accounts I use, the cash traps I avoid, and the simple rule that keeps me from doing something stupid when prices start rising and the headlines get scary.
The scale of the problem
According to the FCA, roughly 8.5 million UK adults hold over £10,000 in cash that could potentially be working harder. At 4% inflation, that's £400+ of purchasing power evaporating per year, per person. Collectively, UK savers are losing billions in real terms every year — not through bad investments, but through no investments at all.
The cash trap: why "safe" savings are costing you money
Let's start with the biggest inflation mistake I see — and the one I made myself for years. Keeping too much money in cash. I'm not talking about your emergency fund — that should absolutely be in cash, instantly accessible, and I'll come back to that. I'm talking about the money beyond your emergency fund. The money sitting in easy-access savers, notice accounts, premium bonds, and current accounts "just in case". The money that feels responsible because it's not being spent, but is actually losing value every single day.
The brutal maths of cash savings
| Scenario | Nominal return | After 3% inflation | After 5% inflation |
|---|---|---|---|
| Easy-access saver (4%) | +4.0% | +1.0% | -1.0% |
| Premium bonds (median ~3%) | ~3.0% | ~0.0% | ~-2.0% |
| Current account (0.1%) | +0.1% | -2.9% | -4.9% |
| Global equity ETF (historical avg 5-7% real) | 7-10% | +4-7% | +2-5% |
All figures illustrative. Equity returns are historical averages and NOT guaranteed. Premium bond median is approximate. Past performance does not predict future returns.
The "safe" option — cash in the bank — is treading water at best. At worst, if inflation spikes again like it did in 2022, it's a guaranteed real-terms loss. Premium bonds are no better. The prize fund rate is advertised as a headline number, but the actual return for most people — the median, not the mean — is considerably lower because the prize distribution is skewed by a small number of large prizes. You might win £25 here and there, but on average, premium bonds have historically returned less than inflation. They're not an investment — they're a savings product with a lottery ticket attached.
What actually beats inflation?
So if cash doesn't protect you from inflation, what does? Historically, three things: equities (shares in profitable companies), property, and inflation-linked bonds. Equities are the most accessible, the most liquid, and — for my money — the most reliable inflation hedge over periods of five years or more.
Why equities? Because when inflation rises, companies can raise their prices. If you own shares in Unilever, and the cost of everything goes up, Unilever charges more for Persil and Domestos and Dove soap. Their revenues rise with inflation. Their profits, over time, tend to rise with inflation. And their share prices, over long periods, tend to reflect those rising profits.
The data bears this out. The Barclays Equity Gilt Study, which has tracked UK asset returns since 1899, has consistently shown that equities outperform inflation over the long term by a wide margin — typically 5-6% per year above inflation over rolling 10-year periods. That's an average, not a guarantee. Gilts (government bonds) have delivered lower but still positive real returns. Cash has barely kept pace. The hierarchy is clear: equities first, then bonds, then cash a distant third for anything beyond your emergency fund.
What I actually hold
My inflation-protection strategy isn't a separate portfolio or a special allocation — it's the same strategy I use for everything else. Broad, low-cost, globally diversified equity ETFs held inside tax wrappers for the long term.
Specifically: VWRP, the Vanguard FTSE All-World UCITS ETF. This single fund owns over 3,700 companies across 40+ countries — developed and emerging markets, large and mid-cap. The ongoing charge is 0.22%. It's my default answer to almost every investing question, and it's my default answer to the inflation question too.
Why a global tracker rather than something more targeted? Because I don't know which countries, sectors, or companies will handle the next inflationary period best. In the 1970s, commodities and energy stocks were the place to be. In the 2010s, US technology stocks delivered extraordinary real returns while commodities languished. The future might look like the 70s or the 2010s or something entirely different. A global tracker means I own a bit of everything — energy companies that benefit from rising commodity prices, technology companies with pricing power and high margins, consumer staples companies that sell things people need regardless of inflation. I don't have to predict which sector wins. I just own them all.
Why I don't hold gold
Some people swear by gold as an inflation hedge. The historical record is mixed — gold has done very well during some inflationary periods and poorly during others. It pays no dividends, generates no earnings, and its price is driven entirely by what someone else will pay for it. That's speculation, not investing, in my view. I prefer to own productive assets — companies that make things, sell things, and generate profits. Those profits tend to rise with inflation over time. Gold just sits there. Your mileage may vary.
The emergency fund: the one place cash belongs
The point of an emergency fund isn't to beat inflation — it's to be there, instantly, when your boiler explodes in January or your car fails its MOT or you lose your job. That money needs to be accessible, stable, and not subject to market movements. A global equity ETF is a terrible place for your emergency fund because you might need the money during a bear market when your £10,000 has become £7,000.
How much? I'm comfortable with 6-12 months of essential expenses. Your number depends on your job security, your health, whether you have dependents, and how much anxiety you can tolerate. But whatever your number, keep it in the highest-interest easy-access account you can find, accept that it will lose a little to inflation each year, and treat that loss as the insurance premium for knowing the money is there when you need it.
Everything beyond your emergency fund and any short-term savings goals (house deposit, car purchase in the next couple of years) should be invested in assets that actually outpace inflation over time.
The simple rule I follow when inflation spikes
When inflation spikes and the headlines get scary — and they will, periodically — I have one rule: do nothing different. That's harder than it sounds. When prices are rising, energy bills are climbing, and every trip to the supermarket costs more than the last one, the instinct to "do something" is powerful. Should I sell? Should I buy gold? Should I move everything to cash and wait it out?
The answer, based on every inflationary period in history that I've studied, is: stay invested in a diversified portfolio of productive assets, keep buying regularly, and give it time. The worst thing I could do is sell my equities and move to cash — locking in any losses and guaranteeing that my money loses purchasing power from that point forward. The second worst thing would be to stop my regular investments — breaking the dollar-cost-averaging habit and trying to time a re-entry. The best thing — the thing I actually do — is absolutely nothing. Keep the auto-invest running. Keep the dividends reinvesting. Ignore the headlines. Check once a quarter.
The real bottom line
Inflation is real, it's relentless, and it's not going away. But it doesn't have to be a threat. Owning shares in profitable, well-run companies across the world — companies that can raise prices, adapt to changing conditions, and generate profits through inflationary and deflationary environments alike — is the best defence I know. Combined with a sensibly-sized emergency fund in cash for the short term, a global equity ETF for the long term, and the discipline to keep buying regardless of what the CPI number says this month, it's a strategy that lets me sleep at night while inflation does its quiet work in the background.
For educational purposes only. Nothing here is financial advice or a recommendation. All investing carries risk — the value of your investments can go down as well as up, and you may get back less than you put in. Past performance — including the historical returns of equities relative to inflation — does not predict future results. Inflation rates, interest rates, and tax rules can and do change. Your circumstances, goals, and risk tolerance are different from mine. Do your own research and consider seeking professional advice where appropriate.
