đ Briefly explained
Inflation refers to the sustained rise in the general price level in an economy. Goods and services become more expensive over a certain period of time. The purchasing power of money falls: for the same amount, you get fewer goods and services than before.
Inflation is usually measured using the Consumer Price Index (CPI). It records the price development of a representative basket of goods that reflects the typical expenses of a household â such as food, rent, energy, or services. If this index rises year over year, this is referred to as an inflation rate in percent.
The distinction between inflation and one-time price increases is important. Inflation is only spoken of when the price level rises broadly and persistently. Its counterpart is deflation â a sustained decline in the price level.
đ Why this is important
Inflation affects everyone who holds, earns, or saves money. It reduces the real purchasing power of income and savings. Anyone who leaves their money in an account without interest loses real wealth as soon as the inflation rate exceeds the interest rate.
Inflation is central to monetary policy. Central banks such as the European Central Bank (ECB) or the US Federal Reserve (Fed) pursue inflation targets â often close to 2 percent. They control inflation through key interest rates and other monetary policy instruments. Too-high inflation endangers price stability, while too-low or negative rates can slow the economy.
Inflation is also relevant for companies, wages, and contracts. It influences wage negotiations, interest rate levels, credit conditions, and the planning certainty of all market participants.
đ Key points
- Definition: Sustained rise in the general price level.
- Measurement: Consumer Price Index (CPI), sometimes also the harmonized HICP in the EU.
- Purchasing power: Falls as inflation rises â money becomes worth less in real terms.
- Causes: Demand-pull inflation (excess demand), cost-push inflation (rising production costs), imported inflation, money supply growth.
- Types: Creeping inflation (low), galloping inflation (high), hyperinflation (extreme).
- Target: Many central banks aim for around 2 percent inflation per year.
- Opposite term: Deflation â sustained decline in prices.
- Real vs. nominal values: Nominal values are unadjusted, real values are adjusted for inflation.
đ§ What investors should pay attention to
- Real return: The actual return is calculated as the nominal return minus the inflation rate. A nominal return of 3 percent with 3 percent inflation means a real return of zero.
- Asset classes: Real assets such as stocks, real estate, or commodities are often considered better long-term inflation protection than pure cash holdings.
- Bonds: With fixed-income bonds, inflation reduces the real return. Inflation-indexed bonds offer a certain degree of protection here.
- Diversification: Broad diversification across asset classes, regions, and currencies reduces the risk of one-sided inflation exposure.
- Interest rate environment: Rising inflation often leads to rising interest rates â this weighs on bond prices but can increase savings rates.
- Time horizon: Markets fluctuate in the short term, but in the long term, preserving real wealth is what matters.
- Consider costs: Fees and taxes also affect the real return â inflation amplifies this effect.
đ Conclusion
Inflation is the sustained rise in the general price level and thus a direct attack on the purchasing power of money. It is not a one-time event but a lasting process that influences saving, investing, and planning. Central banks control it through monetary policy, usually with a target of around 2 percent. For investors, it is crucial to look not only at nominal returns but also at real returns and to position the portfolio for the long term against loss of purchasing power. Anyone who understands inflation can make more informed financial decisions.
