Inflation
Inflation is a general rise in the price level over time. As prices climb, each unit of money buys less, so its purchasing power falls.
How inflation is measured
Statistics offices track the price of a basket of everyday goods and services, such as food, rent, energy and transport. The best-known gauge is the consumer price index (CPI). If the basket costs 100 euros one year and 103 euros the next, annual inflation is 3 percent.
Inflation is about the general price level, not one item. Coffee getting more expensive while electronics get cheaper is a change in relative prices; inflation means most prices are drifting up together.
What causes it
Common explanations include demand outpacing what the economy can produce, rising costs such as energy or wages passed on to customers, and growth in the money supply that is faster than growth in output. Expectations matter too: if people expect higher prices, they may demand higher wages and set higher prices, which can make inflation self-reinforcing.
Most major central banks aim for low, stable inflation, often around 2 percent a year, rather than zero. They mainly steer it with interest rates.
An example
Say you keep 10,000 euros in cash while inflation averages 3 percent a year. After ten years the notes still say 10,000, but they buy roughly what about 7,400 euros bought at the start. Nothing was stolen; the money simply buys less.
Why crypto markets watch inflation
Bitcoin was designed with a fixed issuance schedule, and some people hold it as a hedge against currency debasement. In practice, crypto prices have often reacted to inflation data indirectly: high inflation can lead central banks to raise rates, which tends to weigh on riskier assets. The relationship is not stable and should not be treated as a rule.
Note that crypto tokens can have their own inflation, meaning a growing token supply from new issuance, which dilutes existing holders.

Frequently asked questions
Is inflation always bad?
Moderate, predictable inflation is considered normal and is targeted by many central banks. High or volatile inflation hurts savers and makes planning difficult.
What is the difference between inflation and deflation?
Inflation is a general rise in prices; deflation is a general fall. Persistent deflation can also be harmful because people delay spending and debts become heavier.
Is Bitcoin an inflation hedge?
Its supply is capped, which is why some see it as one, but its price has often moved more with overall risk appetite than with inflation data. Over shorter periods it has not reliably protected against inflation.
