Introduction
To evaluate how well an economy is performing, governments and economists track a range of macroeconomic indicators. These indicators show how successfully an economy is achieving key goals such as sustained economic growth, low inflation, low unemployment and a healthy balance of payments.
Inflation
Inflation is the sustained increase in the general price level of goods and services over time. A common measure is the Consumer Price Index (CPI), which tracks price changes of a representative basket of goods and services consumed by households. CPI inflation shows how much prices have risen and whether purchasing power is being eroded. In many countries an annual inflation rate of 2 to 3 per cent is considered acceptable, reflecting moderate price increases consistent with growth without undermining consumer welfare.
In Singapore, two measures are often cited: CPI-All Items inflation and core inflation. CPI-All Items includes all price changes, including volatile components such as accommodation and private transport, while core inflation excludes these because they may not affect all households uniformly and can be heavily influenced by government policies such as COE quotas or changes in housing supply. This distinction lets policymakers focus on persistent drivers of inflation. In a year where accommodation and private transport costs fall, CPI inflation might show deflation of about minus 1 per cent, while core inflation might still reflect mild inflation of around 1 per cent.
Unemployment
Unemployment occurs when individuals who are actively seeking jobs are unable to find employment. The unemployment rate is the standard measure, expressed as the number of unemployed divided by the total labour force, multiplied by 100. A low rate is desirable, as it indicates that labour is being used effectively. For small open economies like Singapore, a rate of 2 to 3 per cent is considered healthy, accounting for frictional and structural unemployment, while larger, more diverse economies may accept 3 to 5 per cent as a natural rate.
Balance of payments
The Balance of Payments (BOP) is a comprehensive record of a country's economic transactions with the rest of the world. It includes the current account, covering trade in goods and services, income flows and transfers, and the capital and financial account, covering investments and financial transactions. A surplus indicates that inflows such as export earnings and investment receipts exceed outflows such as import spending and capital outflows, generally seen as a sign of strength. A persistent deficit raises concerns over competitiveness and sustainability, as it may require borrowing from abroad or drawing down foreign reserves, which can undermine financial stability.
Economic growth
Economic growth is most commonly measured by the increase in real Gross Domestic Product, the total value of all final goods and services produced in a country, adjusted for inflation. Real GDP gives a clearer picture than nominal GDP, which can be distorted by price changes. In Singapore, reports often refer to GDP at 2020 prices, comparing GDP year on year using 2020 as a base year, which isolates changes in output volume from price changes. A developed economy like Singapore is generally considered to enjoy healthy growth when real GDP rises by 3 to 4 per cent per year, reflecting strong aggregate demand, rising productivity and improving living standards, while negative or stagnant growth signals slowdown or recession.
Conclusion
The key indicators used to measure economic performance include inflation, unemployment, the balance of payments and economic growth. Together they provide a multidimensional view of an economy's health. In Singapore's case, close monitoring and prudent policymaking around these indicators have helped the country navigate global challenges and maintain macroeconomic stability.
