The source video discusses how inflation can reduce purchasing power and argues that a low level of inflation may support the economy. To read that argument clearly, it helps to separate everyday language from standard economic definitions. Low inflation is not automatically harmful, but neither is every rate of inflation beneficial. This guide explains the difference and adds context from the Bank of Thailand and historical sources.
What does inflation mean?
In everyday reporting, inflation usually means that the overall prices of goods and services are rising over time. A price index such as the Consumer Price Index tracks changes across a basket of goods and services. A higher price level means money buys less than before, although individual prices can move in different directions.
Price inflation and money-supply growth are different measures
Economists and commentators sometimes use “inflation” to refer to growth in the money supply. That is a separate measure from consumer-price inflation. Changes in money supply can influence spending and prices, but comparing M2 with GDP is not, by itself, a direct measure of changes in the prices households pay.
Inflation, disinflation, and deflation
Inflation means the general price level is rising. Disinflation means prices are still rising, but at a slower rate. Deflation is a persistent, broad-based decline in the prices of goods and services. A discount on a few products or a fall in one category does not by itself mean that an economy is experiencing deflation.
Why central banks aim for stable, moderate inflation
Stable and predictable prices help households and businesses make plans. The Bank of Thailand’s 2026 medium-term target for headline inflation is 1.0–3.0 percent. The target also aims to prevent deflation and supports price stability, sustainable economic growth, and financial stability. This is a policy objective for Thailand, not a claim that any amount of inflation is good for every household.

Low inflation is not always deflation
Whether a low inflation reading signals deflation depends on the breadth and persistence of price declines and on the wider economic conditions. In its 2025 third-quarter report, the Bank of Thailand explained that lower energy or food prices can pull down headline inflation without a broad-based decline in prices. The report also distinguishes supply-driven price changes from a deflationary pattern in which consumers and businesses expect prices to keep falling.
See the Bank of Thailand’s analysis of whether Thailand’s low inflation was deflationary.
Why sustained deflation can be difficult
If households expect prices to keep falling, some may delay purchases. Businesses may then reduce production, investment, or hiring, which can put further pressure on incomes and demand. The effect depends on the cause and the conditions; it is not an automatic result of every price decrease.
The Federal Reserve’s history of the Great Depression describes several interacting causes, including the 1929 stock-market crash, banking panics, and wider financial crises. It also explains how severe deflation increased debt burdens and damaged consumption and employment. The episode is a historical example, not proof that every period of low inflation will become a depression.

What about gold, money, and economic downturns?
Gold standards and monetary policy have shaped how governments responded to past downturns, but gold alone does not explain every episode of deflation. During the Great Depression, the gold standard affected policy choices while banking failures and a falling money supply also played major roles. Economic crises usually have multiple causes.
Stagflation: slow growth with inflation
The standard term for a period of weak or stagnant economic growth alongside high inflation is “stagflation.” It describes a difficult combination, but it is different from deflation, which refers to broad and persistent falls in prices.
How to interpret claims about inflation
- Check whether a claim refers to consumer prices, the money supply, or a particular category of goods.
- Distinguish a slower increase in prices from a broad decline in prices.
- Look at the causes and breadth of price changes, not only the headline rate.
- Treat historical examples as context, not as a prediction that the same outcome will happen again.
- Use official data and policy explanations when assessing current conditions.
Summary
Inflation, disinflation, and deflation describe different patterns in prices. Low inflation is not necessarily deflation, and a moderate, predictable rate may be part of a central bank’s price-stability framework. Sustained, broad-based price declines can create serious problems, but their causes and effects depend on the wider economy.
