Inflation and Investing: How to Protect Your Assets from Devaluation

At an inflation rate of 2 percent, cash in a current account loses about 18 percent of its purchasing power over ten years. Those who want to protect their money need investments that at least offset the inflation rate. Tangible assets such as stocks, real estate and gold are considered the most effective protection, combined with broad diversification across multiple asset classes. Perfect inflation protection does not exist, but the combination makes the difference.

What is Inflation?

Inflation refers to a sustained increase in the general price level in an economy. The result is simple: for the same amount of money, you get fewer goods and services than before. Money loses value without any change to your nominal account balance.

Purchasing Power Shrinks Gradually

Many savers do not notice this currency devaluation immediately. The account balance remains the same or even increases slightly through interest. In real terms, purchasing power still declines if prices rise faster than interest payments.

Inflation, Deflation and Price Level

The opposite is deflation: the price level falls. From an economic perspective, deflation is considered more dangerous because falling prices inhibit consumption and investment. Consumers then postpone purchases and demand collapses.

How is Inflation Calculated?

Inflation is measured using the Consumer Price Index, which the German Statistical Office collects monthly. It represents a representative basket of approximately 700 goods and services.

The Basket and Its Weighting

Individual items contribute to the inflation rate with varying weights. The weighting in the basket (base year 2020) is distributed as follows:

• Housing, water, electricity, gas: 25.9 percent
• Transport: approximately 13 percent
• Food and non-alcoholic beverages: 11.9 percent
• Health: 5.5 percent
• Clothing and footwear: 4.2 percent

The European Central Bank's Inflation Target

The European Central Bank targets an inflation rate of 2 percent as a symmetric objective. It fights deviations above and below equally. This strategy was established in July 2021.

Why Your Account Balance is Misleading: Nominal vs. Real Value

The key term is real interest rate. It is the nominal rate minus the inflation rate. If the interest rate paid is below the inflation rate, you suffer a real loss of purchasing power despite positive interest.

An Example Calculation of Purchasing Power Loss

If you invest 1,000 euros at 1 percent interest while inflation is 2 percent, the balance after ten years looks like this:

• Nominal capital: approximately 1,104 euros
• Real purchasing power: only about 906 euros

The nominal interest rate creates an illusion of gains. In real terms, you have lost wealth.

Why Inflation Often Feels Higher

Personal inflation rates can differ significantly from the official rate. Those with high rents or energy costs feel a greater burden than the Consumer Price Index indicates. The basket is an average, not an individual spending profile.

Inflation in Germany: Figures from Recent Years

Germany's inflation rate has moved significantly in recent times. The annual averages according to the German Statistical Office:

• 2020: +0.5 percent
• 2021: +3.1 percent
• 2022: +6.9 percent
• 2023: +5.9 percent
• 2024: +2.2 percent
• 2025: +2.2 percent

After peaking in 2022, currency devaluation has moved closer to the ECB target. For investing, the pressure to act remains.

What are the Consequences of Inflation?

The effects of inflation affect savers and borrowers differently. Those holding cash lose in real terms. Those with debt benefit because the real value of their debt decreases.

Savers Lose, Borrowers Gain

If wages do not rise at the same pace as prices, living standards fall. At the same time, inflation devalues existing loans. For investing, this means: inaction is the most expensive option.

Inflation and Investing: The Basic Principle Against Currency Devaluation

The central question in inflation investing is: how does my capital achieve returns above the inflation rate? To offset currency devaluation, investments should generate at least 2 percent returns, based on current inflation levels.

Why Broad Diversification Matters

A single product offers no complete protection. Only the combination of various asset classes smooths out fluctuations and combines safety with return opportunities. Diversification is the most effective tool to avoid purchasing power loss.

Investing in Stocks or ETFs as Inflation Protection

Stocks are historically considered the strongest real asset protection. Companies can pass rising prices on to their customers; their profits grow with the price level. Over long periods, broadly diversified stocks significantly outpace inflation.

ETFs as a Pragmatic Core

For private investors, broadly diversified equity ETFs are the most pragmatic component of an inflation-resistant portfolio. An ETF replicates an index such as the DAX or a global index and incurs lower costs than actively managed funds.

Investment Funds and Equity Funds

Investment funds enable broad diversification even with small amounts. Equity funds combine many individual securities in one product. Those who invest regularly through a savings plan in ETFs or funds do not need to find a perfect entry point.

Managing Price Fluctuations

Stocks fluctuate significantly in the short term. During periods of rising interest rates or stagflation, they can decline sharply. Inflation protection works only over years and decades, which is why an investment horizon of at least ten years is advisable.

Tangible Assets Against Currency Devaluation

In addition to stocks, other tangible assets are among the preferred investment forms during inflationary times. Their common advantage: they are tied to real values and not to a fixed monetary amount.

Real Estate as Classic Inflation Protection

Real estate is considered a classic component of an inflation protection portfolio. Rents are often indexed to the Consumer Price Index and rise with inflation. Direct ownership, however, creates concentration risk because large amounts of capital are tied up in one property.

Real Estate ETFs and REITs

Those wanting broader diversification can turn to real estate ETFs or REITs. They make real estate investments accessible even with small amounts and spread risk across many properties and locations. This way, the tangible asset advantage can be achieved without purchasing an individual property.

Gold and Commodities for Hedging

Gold traditionally serves as a crisis hedge and for diversification. An allocation of around 5 to 10 percent is common. Commodities often behave differently than stocks and bonds but provide no ongoing income. Gold yields neither interest nor dividends; its value is determined solely by market price.

Bonds and Inflation-Indexed Securities

Traditional bonds suffer from inflation because their fixed interest rate loses value in real terms. Inflation-indexed bonds tie their returns to the inflation rate and protect the real yield.

Access Through UCITS ETFs

Such securities are accessible through specialized UCITS ETFs, for example on TIPS or Euro-Linker. Note: since 2024, the German government has not issued new inflation-indexed federal securities, so access is mainly through funds.

Savings Accounts and Fixed-Rate Deposits: Safe, but Rarely Inflation-Proof

Savings accounts and fixed-rate deposits are very secure due to statutory deposit insurance of 100,000 euros per bank and customer. As a return component during inflationary periods, they are usually not suitable.

Real Interest Rate Often Remains Negative

Following the interest rate turnaround, top providers are offering over 3 percent on savings accounts again (as of January 2026). Many banks and savings banks still offer 0 to 1 percent. At approximately 2.3 percent inflation and 2 percent savings account interest, the real interest rate is about minus 0.3 percent.

Liquidity Reserve Rather Than Return Generator

Savings accounts and fixed-rate deposits have their fixed place as emergency funds. Two to three months of net salary in a savings account is recommended. Fixed-rate deposits can be spread across different terms, for example divided into one, two and three years, to remain flexible.

Compare Interest Rates and Switch Banks if Needed

If your bank's interest rates are significantly below top offers, switching providers makes sense. Fees for negative interest rates, which many banks imposed during the low interest rate period, have been largely eliminated since 2022.

Investing During Inflation: A Portfolio in Building Blocks

Those who want to invest during inflation should best combine multiple components. Each serves a different function in the portfolio.

The Building Blocks at a Glance

• Broad equity ETFs: long-term core, historically strongest real asset protection, investment horizon of at least ten years
• Real estate and REITs: tangible assets with inflation protection through often indexed rents
• Gold and commodities: crisis hedging, approximately 5 to 10 percent allocation
• Inflation-indexed bonds: defensive portion with protected real yield
• Savings accounts and fixed deposits: liquidity reserve, not a return component

Allocation Based on Risk Tolerance

Before investing, define your investment objective. The allocation depends on assets, investment horizon and risk tolerance. Those who can tolerate more volatility weight stocks higher; those who prefer safety strengthen the defensive portion.

Practical Tips Against Purchasing Power Loss

To avoid purchasing power loss, a few consistently implemented rules help more than frequent rebalancing. The following points can be applied immediately.

Seven Action Recommendations

1. Aim for at least 2 percent returns to offset inflation.
2. Calculate the real interest rate in every calculation, not just the nominal rate.
3. Spread fixed-rate deposits across different terms and remain flexible.
4. Compare interest rates regularly and switch banks if necessary.
5. Pay attention to the 100,000 euro deposit insurance limit per bank and customer.
6. Invest disciplined through a savings plan rather than trying to time the market.
7. Focus on low costs, as high fees reduce returns.

What Happens to Cash During Inflation?

Cash and non-interest bearing deposits lose the most. At 2 percent inflation, purchasing power melts away by about 18 percent over ten years. The solution is not rapid spending but broad diversification across asset classes.

The Role of Monetary Policy: ECB and Policy Rate

The level of inflation and interest rates are closely linked. If the money supply grows too quickly or demand exceeds supply, prices rise. The European Central Bank counters this through its policy rate.

Interest Rate Turnaround and Current Development

In 2024, the ECB cut its policy rates multiple times due to declining inflation. In June 2026, a further increase followed to a deposit rate of 2.25 percent. For savings accounts, this means fluctuating conditions; for investors, the need to keep the real interest rate in focus.

Taxes and Legal Framework

With every investment, taxes reduce returns. After deducting capital gains tax, real returns decline further. Legal frameworks for savings and deposit insurance are set by the Federal Ministry of Justice and Consumer Protection. Those planning realistic returns factor in taxes and the inflation rate together.

Is Saving Worth It During Inflation?

Saving remains worthwhile, but simply holding funds in a current account or savings book is not. Without interest rates above the inflation rate, losses worsen year after year.

Saving with Strategy

Combine a liquidity reserve in a savings account with higher-return investments. This keeps you capable of action while simultaneously protecting most of your capital from currency devaluation.

Common Mistakes in Investing During Inflationary Times

Experience from many private investors reveals recurring mistakes. They cost returns and unnecessarily increase risk.

Typical Pitfalls

• Excessive cash holdings beyond necessary reserves
• Lack of diversification across asset classes and maturities
• Panic sales during short-term price fluctuations
• Ignoring real interest rates in favor of nominal rates

Those who avoid these points reduce the likelihood of costly losses.

Extreme Cases: Hyperinflation

Hyperinflation refers to price increases that spiral out of control, sometimes exceeding 50 percent per month. In such scenarios, investors flee to tangible assets because money loses value rapidly. For the German investor, hyperinflation is not a realistic scenario at present, but it clearly illustrates the logic behind tangible assets.

Conclusion: Tangible Assets as the Core of Inflation Protection

Complete protection from inflation does not exist, but a well-thought-out portfolio comes close. Broadly diversified stocks and ETFs form the core, real estate, gold and inflation-indexed bonds supplement it, savings accounts secure liquidity. Those who invest disciplined and keep real interest rates in focus can effectively limit purchasing power loss. Further analysis and current market data are available continuously at aktie.com.
