Inflation refers to the general and lasting increase in the prices of goods and services. When it exceeds the net return on your savings, every euro invested loses real value, even if the amount displayed in your account remains the same. Protecting your money against inflation requires understanding this mechanism and acting on the areas where erosion is strongest.
Perceived inflation and official inflation: the costly gap
The consumer price index published by statistical institutes aggregates hundreds of categories. The overall figure can decrease, as was the case in France during 2025, while masking a harsher reality regarding everyday expenses.

The European Central Bank documented this phenomenon in its Economic Bulletin No. 3 of 2025: inflation on essential expenses remains higher than the general index. Food, rent, energy—these categories weigh more heavily in the budgets of modest and middle-income households than in the average statistical basket.
This discrepancy has a direct consequence: even when official inflation declines, the purchasing power of uninvested cash continues to erode. Following Ei Mag’s advice helps to better frame this reality and adjust investment choices accordingly.

The first step to protect your money is therefore to measure your own inflation, the one that corresponds to your actual expenses, not the national average.
Nominal illusion of so-called secure investments
Regulated savings accounts, euro-denominated life insurance funds, term accounts: these products promise capital security. The trap is that they guarantee an amount in euros, not purchasing power.
The European Insurance and Occupational Pensions Authority (EIOPA) warned in its Consumer Trends Report of December 2024 about what it calls the risk of nominal illusion. A significant portion of contracts sold in 2024-2025 show net taxed returns lower than the projected average inflation.
In simple terms, your “guaranteed” capital makes you less wealthy each year if the rate provided does not cover the price increase. Capital guarantee is not a guarantee of real value.
How to spot a hidden real loss
Take the announced yield rate from your contract. Subtract social contributions and taxes. Compare the result to the inflation on your essential expenses, not to the overall index. If the balance is negative, your savings are losing purchasing power despite a positive displayed yield.
This calculation takes a few minutes and often changes the perspective on investments perceived as “risk-free.”
Paying off debts: an underestimated anti-inflation lever
Discussions about protection against inflation almost always revolve around investments. Several empirical studies published since 2023 show that another lever deserves equal attention: the early repayment of variable or adjustable rate debts.
The reasoning is simple. A variable rate loan adjusts upward when rates rise, which often happens during inflationary periods. The real cost of this debt increases. Partially repaying this loan amounts to “investing” the sum at a rate equal to the interest saved, with no market risk and no additional taxation.
For households that hold both an adjustable loan and low-yield savings, the trade-off is worth considering. Reducing an indexed debt can improve future purchasing power more than investing the same amount in a defensive product.
Tangible assets and diversification against rising prices
Once the nominal illusion is identified and costly debts are addressed, the question of investment itself arises. Three categories of assets have historically shown the ability to keep pace with or exceed inflation over the long term.
- Rental real estate: rents are partially indexed to the price index, providing income that adjusts upward. Real estate retains tangible value, although liquidity remains low and entry costs are high.
- Stocks of companies with pricing power: these companies pass on their rising costs to customers, thus protecting their margins and the value of their shares. Broad index funds offer diversified exposure to this mechanism.
- Inflation-linked bonds: their coupon and redemption value adjust to the price level. They play a direct hedging role against monetary erosion in a bond portfolio.
Distribute rather than concentrate
No asset outperforms in all inflation scenarios. Real estate suffers when rates rise sharply. Stocks can drop at the beginning of an inflationary cycle. Inflation-linked bonds protect capital but offer modest real returns.
Combining these three categories in a portfolio suited to your investment horizon and risk tolerance remains the most robust strategy. Diversification does not eliminate risk, but it limits concentration on a single scenario.
Personal budget and income indexing
Protecting your money against inflation is not only about choosing investments. Mastering your budget and the ability to adjust your income play an equally concrete role.
- Renegotiate your recurring contracts (insurance, energy, subscriptions) at least once a year to eliminate unjustified automatic increases
- Ensure that professional income at least keeps pace with perceived inflation, using sector data as a basis for salary negotiations
- Automate savings into vehicles with positive real yields rather than leaving excess funds in a zero-interest checking account
These regular adjustments, combined with thoughtful asset allocation, form a coherent protective mechanism against rising prices.
The last point to keep in mind: the European Central Bank targets an inflation rate of around two percent in the medium term. A portfolio that does not generate at least this level of net real yield declines each year, even when markets seem calm.
