Introduction
Inflation is a sustained increase in the general price level of goods and services over time. In Singapore, inflation is influenced by demand-pull inflation, cost-push inflation and imported inflation. Demand-pull inflation occurs when aggregate demand rises beyond the economy's productive capacity, cost-push inflation arises from rising production costs that firms pass on to consumers, and imported inflation results from higher prices of imported goods due to external factors such as global supply chain disruptions. In the current climate, Singapore faces pressure from both demand-side and supply-side factors, including increased consumer spending after COVID-19 restrictions eased, geopolitical tensions affecting food and energy prices, and a tight labour market.
Demand-pull inflation, a demand-side reason
A key demand-side factor is the surge in consumption and net exports following the easing of COVID-19 restrictions. The removal of travel bans, social distancing and mask mandates improved consumer confidence and encouraged greater spending, so consumption, a major component of aggregate demand, rose significantly. The reopening of international borders also revived tourism, raising tourist arrivals and spending and lifting net exports, which further increased aggregate demand. Because Singapore operates at or near full employment in a tight labour market, the rise in aggregate demand translates more directly into higher prices than into higher output, since there is little spare capacity to absorb the extra demand. This is shown by an increase in aggregate demand that raises the general price level by much more than it raises real national output, producing demand-pull inflation.
Imported inflation, a supply-side reason
A significant supply-side factor is the rise in global food and commodity prices due to the Russo-Ukrainian war. Russia and Ukraine together account for nearly a third of the world's wheat supply, and Ukraine is also a major exporter of corn and sunflower oil. Economic sanctions on Russia and the disruption caused by the war have severely constrained the supply of these goods, raising global prices for food, fertilisers and raw materials. Because Singapore imports the vast majority of its food and essential commodities, it is highly vulnerable to these external shocks, so when global import prices rise the cost of living increases. This imported inflation occurs when higher import prices translate directly into higher domestic prices.
Cost-push inflation, a further supply-side reason
Another supply-side factor is the rise in production costs from global supply chain disruptions. The worldwide shortage of semiconductors caused production stoppages for many electronics manufacturers and raised the cost of producing various goods, and the Russo-Ukrainian war sharply increased the prices of raw materials such as steel and fertilisers. As firms face higher production costs they pass them on to consumers as higher prices, producing cost-push inflation, shown by a leftward shift of the short-run aggregate supply curve that raises the general price level. Because Singapore is highly import-dependent, the rise in global input costs has contributed significantly to domestic inflationary pressure.
Conclusion
Singapore's recent rise in inflation is driven by both demand-side and supply-side factors. On the demand side, the rebound in consumption and tourism raised aggregate demand in an economy near full employment, pushing up prices. On the supply side, external shocks from the Russo-Ukrainian war and global supply chain disruptions raised import and input costs, causing imported and cost-push inflation. These overlapping pressures show the complexity of managing price stability in a small, open economy where both domestic recovery and external vulnerabilities must be monitored carefully.
