Inflation

Inflation is the quietest force in investing. It never crashes, never trends on your feed, and it takes a slow bite out of every euro you don't put to work. Understand it and half the "get rich" pitches stop making sense.

What it actually is

Inflation is the general rise in prices over time — equivalently, the fall in what one unit of money can buy. At 3% inflation, the €100 in your account buys about €97 worth of last year's stuff. Nothing was stolen; the ruler just got shorter.

Nominal vs. real: the number that matters

This is the whole game. A nominal return is the headline: "up 7% this year." A real return is what's left after inflation — the part that actually grows your purchasing power.

If your account is up 7% and inflation ran 8%, you didn't make money — you lost about 1% in real terms. The balance went up; what it can buy went down. Any return quoted without mentioning inflation is telling you half the story.

What history says about beating it

Over long horizons, the picture is fairly consistent:

  • Cash is the reliable loser to inflation. Safe in nominal terms, quietly shrinking in real terms — that's its job description.
  • Stocks have, over long periods, outpaced inflation by a comfortable margin, because companies can raise their own prices too. Not smoothly, and not guaranteed — but the long-run real return on broad equities has been solidly positive.
  • Inflation-linked government bonds (TIPS in the US, index-linked gilts, and so on) are the one asset explicitly designed to track inflation, by adjusting their payout to it.
  • Gold gets sold as "the" inflation hedge, but its record is mixed — a rough long-run store of value, yet unreliable over the shorter stretches when people actually reach for it. A claim worth checking rather than accepting.

The short version

  • Inflation is the slow erosion of what money buys — the tax you pay for holding cash.
  • Judge every return in real terms: nominal minus inflation. "Up 7%" in an 8% year is a loss.
  • Historically, equities have beaten inflation over the long run; cash reliably hasn't.
  • The "gold = inflation hedge" story is shakier than advertised — exactly the kind of claim we like to check.
Not advice — a reminder. This explains how inflation works, not what to buy to beat it. Real returns, taxes and your own timeline all interact; for a plan, talk to a fee-only fiduciary adviser.
