Key takeaways
- Inflation is the rate at which the prices of goods and services rise over time, reducing the purchasing power of each dollar you hold.
- Economists measure inflation using a consumer price index (CPI), which tracks price changes in a fixed basket of goods and services that households commonly buy.
- Prices can rise because demand outpaces supply, input costs increase, or wages and prices push each other higher in a cycle.
- For small businesses, inflation often means higher operating costs, tighter margins and customers who watch their spending more closely.
Inflation definition
Inflation is the rate at which the average price of goods and services rises over a period of time. Statisticians measure it by tracking price changes in a "basket" of items that households typically buy, from groceries and rent to transport and healthcare.
As prices climb, each dollar in your pocket buys a little less than it did before. This gradual loss of purchasing power is why understanding inflation matters for anyone running a business or managing personal finances.
What is the inflation rate?
The inflation rate is the percentage by which prices rise over a set period, usually reported on an annual basis. It gives you a single figure that summarises how much more expensive a typical basket of goods has become compared to the previous year.
Keep in mind that the rate is an average. Different categories move at different speeds: transport costs might jump while clothing prices stay flat, or food might rise faster than entertainment.
How to calculate the inflation rate
The formula in words is: (new price − old price) ÷ old price × 100.
For example, if an item costs HK$100 today and rises to HK$103 next year, the calculation is (103 − 100) ÷ 100 × 100 = 3. That item experienced 3% inflation over the year.
How inflation is measured
Governments track inflation through a consumer price index (CPI). A CPI follows the price of a fixed basket of goods and services, weighted to reflect typical household spending.
In Hong Kong, the Census and Statistics Department publishes the Composite CPI, along with three sub-indices: CPI(A) for lower-spending households, CPI(B) for medium-spending households and CPI(C) for higher-spending households. The Composite CPI blends all three to give a single headline figure.
What causes inflation?
Prices can rise for several reasons, and economists group them into three broad categories. Understanding each helps you see where cost pressures come from.
Demand-pull inflation
When buyers want more goods and services than producers can supply, competition for limited stock pushes prices up. This often happens during strong economic growth or when government stimulus puts extra money in consumers' pockets.
Cost-push inflation
Rising input costs, such as higher energy prices, more expensive imported goods or increasing wages, force businesses to charge more. The pressure starts on the supply side and works its way through to shoppers at the till.
Built-in inflation
Sometimes wages and prices push each other higher in a self-reinforcing loop. Workers ask for pay rises to keep up with the cost of living, businesses pass those costs on, and prices climb again. Economists call this the wage-price spiral.
Inflation, deflation and related terms
Inflation sits on a spectrum of price movements. Here are a few terms you may encounter when reading economic news:
- Deflation: a sustained fall in the general price level, meaning money buys more over time.
- Disinflation: a slowdown in the rate of inflation, where prices still rise but at a gentler pace.
- Hyperinflation: extremely rapid, out-of-control price increases, often exceeding 50% a month.
- Stagflation: a combination of high inflation, stagnant economic growth and high unemployment.
Inflation in Hong Kong
Hong Kong's inflation picture reflects its open economy and unique monetary system. Official figures come from the Census and Statistics Department.
Hong Kong's Composite Consumer Price Index rose 2.0% year on year in June 2026. Underlying inflation, which nets out one-off government relief measures, was 1.9%, according to a government press release. You can find historical data and methodology on the Census and Statistics Department website.
Because the Hong Kong dollar is pegged to the US dollar at HK$7.80, within a band of HK$7.75 to HK$7.85, under the Linked Exchange Rate System, Hong Kong largely follows US interest-rate moves rather than setting its own. This arrangement shapes how inflation is managed locally.
Why inflation matters to small businesses
Inflation can occasionally work in your favour. The cash value of assets like property or inventory may rise, and any fixed-rate debt you hold shrinks in real terms over time. However, for most small businesses, inflation brings more challenges than benefits.
- Passing rising costs on to customers is difficult when they are already watching their budgets.
- Discretionary spending often falls as households prioritise essentials.
- Borrowing costs can climb when central banks raise interest rates to cool the economy.
If you want to protect your business against rising costs, preparation and visibility are key.
How small businesses can deal with inflation
There is no single fix, but a few tactics can help you stay resilient when prices are climbing:
- Cut business costs by switching suppliers, renegotiating leases or trimming discretionary spending.
- Monitor your profit margins closely so you spot erosion before it becomes a crisis.
- Raise prices strategically, communicating the change clearly to customers.
- Build a cash flow forecast to manage liquidity and plan for slower-paying customers.

FAQs on inflation
Here are answers to some common questions about inflation and how it affects small businesses.
What is a healthy inflation rate?
Most central banks target annual inflation of around 2%, which is low enough to preserve purchasing power while allowing room for economic growth.
What is the difference between inflation and deflation?
Inflation means prices are rising over time, reducing what your money can buy. Deflation is the opposite: prices fall, so each dollar stretches further, though prolonged deflation can signal weak demand and economic trouble.
What is Hong Kong's current inflation rate?
As of June 2026, Hong Kong's Composite Consumer Price Index rose 2.0% year on year, according to the Census and Statistics Department.
How does inflation affect my purchasing power?
When prices rise faster than your income, you can buy fewer goods and services with the same amount of money. Over time, this erodes the real value of savings and fixed-price contracts.
How can my small business protect itself from inflation?
Focus on controlling costs, reviewing pricing regularly, maintaining healthy cash reserves and keeping a close eye on your margins. Flexibility and forward planning help you adapt as conditions change.
