What Is Inflation?
Inflation means that prices on goods and services rise broadly across the economy — which means the same amount of money buys less than before. In other words, your purchasing power decreases.

What Happens to €10,000 When Prices Rise
Below is a concrete way to see inflation: imagine you have €10,000 in a savings account, but your money doesn't grow as fast as prices. The purchasing power — what your money can actually buy — decreases over time.
| Inflation per year | After 2 years | After 5 years | After 10 years |
|---|---|---|---|
| 2% | €9,612 | €9,057 | €8,203 |
| 3% | €9,426 | €8,626 | €7,441 |
At 3% inflation, €10,000 loses approximately €2,559 in purchasing power over 10 years — even though the number in your account still says "10,000."

When inflation falls below zero — called deflation — prices drop but the economy slows. The ECB targets 2% annual inflation as the healthy middle ground.
Are Savings Accounts Keeping Up With Inflation?
It feels unfair — and the data confirms it. The money you earn loses value over time, and even though inflation is a well-understood concept, most of us forget about it the moment we put money into a savings account. These accounts feel like they should balance things out. Historically, in many periods, savings accounts have not kept pace with inflation.
Here's what European banks were actually paying in December 2025, compared to an inflation rate of 2.5%:
| Account type | Interest rate | EU Inflation 2025 | Real return |
|---|---|---|---|
| Overnight deposits | 0.25% | 2.5% | -2.25% |
| 3-month notice accounts | 1.22% | 2.5% | -1.28% |
| Fixed term up to 1 year | 1.77% | 2.5% | -0.73% |
Every common savings account type paid below inflation in 2025. In real terms, your money was shrinking — even while earning interest.

Why Do We Keep Choosing Savings Accounts?
It feels safe. Like nobody can touch it. And in one sense that's true — your money sits there, the number doesn't change, and no single person or event can take it from you overnight.
But inflation isn't human. It doesn't knock on your door or send a warning. It works slowly, invisibly, and consistently — and it will reach your savings no matter where you keep them.
The data reflects this psychology. According to the ECB Household Finance and Consumption Survey, nearly every European household — 97.7% — holds a bank deposit of some kind. Direct stock ownership tells a different story: only 8.6% of households hold listed shares. The savings account isn't just common — it's the overwhelming default.
Deep distrust of financial platforms, decision paralysis from too many options, and a mindset that says "at least I won't lose it all." The savings account wins not because it's optimal — but because it feels like the one place where nothing can go catastrophically wrong.
The silent killer doesn't care about that logic. This is part of the €10.8 trillion gap — the scale of European household savings sitting outside capital markets.

€100 Per Month: Savings Account vs Index Fund
What does the same monthly amount look like across two different approaches over 10 years? Based on historical data, the outcomes have differed historically.
| Savings account | Global index fund (MSCI World, broad market example — not a recommendation) | |
|---|---|---|
| Monthly amount | €100 | €100 |
| Total invested | €12,000 | €12,000 |
| After 10 years | €12,150 | €22,593 |
| Growth | €150 | €10,593 |
Savings account rate: 0.25% (ECB overnight deposit rate, December 2025). Index fund: MSCI World 10-year annualised net return in EUR, 12.34% (MSCI factsheet, February 2026). Past performance is not a reliable indicator of future results. Capital is at risk.
Returns from equity markets can vary significantly over time, including periods of negative performance, and depend heavily on the investment period.
What inflation does to both outcomes
These figures show the raw numbers. Inflation reduces the buying power of both. Using the actual average EU27 HICP inflation rate of 2.85% per year between 2015 and 2025 — a cumulative increase of approximately 32.5% — the real purchasing power of each outcome in 2015 euros:
| After 10 years (raw) | Real purchasing power (2015 €) | Real outcome vs €12,000 invested | |
|---|---|---|---|
| Savings account | €12,150 | ≈€9,170 | Lost €2,830 in real terms |
| Global index fund | €22,593 | ≈€17,051 | Gained €5,051 in real terms |
In real terms the difference is close to €8,000 in purchasing power. The gap does not disappear when inflation is applied. It stays large.

Frequently Asked Questions
How does inflation affect my savings account?
Inflation reduces the purchasing power of money over time. If your savings account pays less interest than the inflation rate — which most European accounts did in 2024 and 2025 — your money buys less each year even though the number in your account stays the same. Source: ECB Banking Statistics, Eurostat HICP data.
Should I invest or save monthly?
Both serve different purposes. Savings accounts provide liquidity and security for short-term needs and emergencies. Investing is generally considered more appropriate for money you can leave untouched for five years or more. The question isn't which to choose — it's understanding what each one does to your money over time. Capital is at risk when investing. Source: ESMA Retail Investor Guidelines.
How do I start investing without losing?
There is no way to invest without any risk of loss. Capital is always at risk in market-based investments. What you can control is how much risk you take on, how diversified your investments are, and how long you stay invested. Regulators including ESMA recommend understanding any product before committing money, starting with regulated and diversified funds, and only investing what you can leave untouched for the medium to long term.
