What inflation is and why prices rise: a full guide

Inflation is a general and sustained rise in the prices of goods and services in an economy; as a result, the purchasing power of a unit of money (how much it can buy) falls. This guide sets out what inflation is, how it is measured, its causes, the difference between nominal and real income, how central banks control it, and the current situation in Uzbekistan — based on reputable economic sources, with facts.

What inflation is

Inflation is not the price rise of a single item but a sustained rise in the general price level over time, so the purchasing power of money falls. For example, if annual inflation is 10%, a basket that cost 100,000 som a year ago now costs about 110,000 som — the same money buys less. The opposite of inflation is deflation (a general fall in prices); a slowing of the inflation rate is called disinflation (prices still rise, but more slowly).

How it is measured: the consumer price index (CPI)

Inflation is usually measured by the Consumer Price Index (CPI). The statistics office builds a "basket" of goods and services households buy regularly (food, utilities, transport, clothing, medicine and so on) and tracks the change in that basket's price. Annual inflation is how many percent the basket costs today compared with a year ago. "Core inflation" excludes volatile food and energy prices — it shows the steady part of the pressure.

Causes: demand, cost and the money supply

Economists distinguish several sources of inflation. Demand-pull inflation occurs when demand outstrips supply — people have plenty of money but there are not enough goods. Cost-push inflation occurs when production costs (raw materials, energy, wages, import prices) rise and sellers pass them on. A monetary cause is the money supply growing faster than the economy ("too much money chasing too few goods"). Expectations also matter: if prices are expected to rise, wages and prices are raised in advance and inflation can become self-sustaining.

Nominal vs real: the true value of income

A nominal amount is the figure expressed in money; a real amount is adjusted for inflation, that is, measured by purchasing power. If your wage rises 8% a year but inflation is 10%, your real income has fallen by about 2% — you get more money but can buy less with it. So in judging a saving, salary or loan rate, look not just at the nominal number but at the real (above- or below-inflation) rate.

Why it matters for family and diaspora

Inflation directly affects savings, wages and remittances. Money kept under the mattress or without interest loses value each year to inflation. If local prices rise by the time remittances sent from abroad arrive, their real value falls. High inflation also raises the interest on loans and mortgages. That is why family budgets, savings and investment plans should account for inflation.

How the central bank controls inflation

The main tool for reining in inflation is the central bank's main (policy) interest rate. If the bank raises the rate, credit becomes more expensive, spending and demand fall — easing price pressure. If the rate is cut, the economy is stimulated instead. Many central banks announce an explicit "inflation target" (for example 4–5%) and aim for it; stable, low and predictable inflation makes economic planning easier.

In Uzbekistan: the current situation

The Central Bank of Uzbekistan has set 5% as its inflation target. Through 2026 annual inflation stayed above that target: about 6.4% at mid-year and around 6.2% in September; the Central Bank forecast roughly 6.5% by year-end. The bank has kept its policy rate at 14% through 2026 and has said it will maintain tight monetary policy until disinflation is sustained. According to the International Monetary Fund (IMF), the 5% target is expected to be reached in 2027.

Hyperinflation

Inflation that spirals out of control, reaching tens or hundreds of percent a month, is called hyperinflation. Historical examples include Weimar Germany in the 1920s and Zimbabwe in the late 2000s. Money loses value almost overnight, people are stripped of their savings and trust in the national currency collapses. Uzbekistan itself experienced very high inflation in the early 1990s, during the post-independence transition.
