You probably know the word. Prices go up. Your grandparents tell you a coffee used to cost 500 lire and now it’s €1.20. But what’s actually happening, and more importantly, what does it mean for the money you have right now?
The short version
Inflation is the rate at which the general price level rises over time. If inflation is 3% this year, something that cost €100 in January costs roughly €103 in December. Your €100 bill is still a €100 bill — but it buys you less stuff. That’s the whole trick: inflation doesn’t take money out of your wallet. It takes value out of your money.
Where does it come from?
Economists have argued about this for centuries and will keep arguing. But the short list:
- Demand-pull: Too much money chasing too few things. When everyone wants a house in the same neighborhood, prices go up.
- Cost-push: Production costs rise (energy, raw materials, wages), and companies pass that along to you. The 2022 energy crisis in Europe was textbook cost-push.
- Monetary policy: Central banks print money. More euros chasing the same pile of goods = each euro is worth a little less. The ECB’s job is to keep inflation around 2% — not zero, because a little inflation greases the economic wheels.
In real life, these three blend together. The 2021–2023 inflation spike in Europe started with supply chains (cost-push), got amplified by stimulus spending (demand-pull), and took a while to cool down because the ECB was slow to raise rates (monetary policy).
Why 2% is the target (and not zero)
Zero inflation sounds ideal but actually isn’t. A little inflation:
- Encourages spending and investing. If your money loses 2% of its value every year sitting in a drawer, you’re nudged to do something productive with it.
- Gives central banks room to maneuver. When a recession hits, the ECB cuts interest rates. If inflation were already at zero, rates would have to go negative (and they did, briefly, and it was weird).
- Lubricates wages. Companies hate cutting nominal wages — it feels like a pay cut and morale tanks. But with 2% inflation, a “flat” salary is effectively a small pay cut without the drama.
What this means for your savings
Here’s the bit that matters personally. If your savings account pays 1% interest and inflation is 3%, your money is losing about 2% of its purchasing power every year. After 10 years, €10,000 has the spending power of roughly €8,200.
Nobody sent you a bill for €1,800. No transaction showed up on your bank app. You still have €10,000 (actually €11,046 with compound interest). But what you can buy with it has shrunk. It’s the quietest tax there is.
A quick table
| Years sitting in cash | Inflation 2% | Inflation 4% | Inflation 6% |
|---|---|---|---|
| 5 years | €9,057 | €8,219 | €7,473 |
| 10 years | €8,203 | €6,756 | €5,584 |
| 20 years | €6,730 | €4,564 | €3,118 |
Starting value: €10,000. Shows the real purchasing power — what your money can actually buy — assuming it earns zero interest.
That last row is the gut punch. At 4% inflation over 20 years, your €10,000 has the buying power of €4,564. More than half gone, without touching it.
So what do you do about it?
You can’t stop inflation. But you can stop letting it eat your money:
- Keep an emergency fund in cash — 3 to 6 months of expenses. Accept the inflation loss on this chunk; it’s the price of liquidity and peace of mind.
- Invest the rest. Equities, bonds, real estate — basically anything with a return that historically outpaces inflation. Over the last century, diversified stock indexes have returned 7–10% nominal, or about 5–7% after inflation.
- Think in real terms. When someone says “this fund returned 8% last year,” ask: “what was inflation?” A fund that returns 8% during 6% inflation made you 2% richer. A savings account that pays 3% during 4% inflation made you 1% poorer.
The point isn’t to be anxious about it. The point is that doing nothing is a financial decision — and it’s usually the expensive one.
