Context: Singapore is expected to face rising inflation due to a strong global rebound following COVID-19 vaccines, geopolitical tensions pushing up food and energy prices, and a tightening labour market. In response, the MAS has allowed the Singapore dollar to strengthen and has urged businesses to adopt technology to help manage costs.
Introduction
Singapore's inflationary pressures are driven by both external and domestic factors, including a strong global rebound, surging global commodity prices due to geopolitical tensions, and a tightening labour market. To curb inflation, Singapore relies primarily on a modest and gradual appreciation of the Singapore dollar via its exchange-rate-centred monetary policy, alongside supply-side efforts such as encouraging technological adoption to lower production costs. While these policies can help stabilise prices, they are not without trade-offs in growth, employment and equity.
How exchange rate appreciation helps address inflation
The MAS manages inflation through its exchange rate policy rather than interest rates, adopting a managed float that allows the Singapore dollar (SGD) to appreciate modestly and gradually by adjusting the slope of the policy band. A stronger SGD curbs inflation in several ways. It lowers imported inflation, since an appreciating currency makes foreign goods cheaper in SGD terms, and Singapore imports the vast majority of its food, energy and raw materials. It lowers cost-push inflation, as cheaper imported inputs reduce firms' costs of production, shifting Short-Run Aggregate Supply (SRAS) rightward. And it curbs demand-pull inflation, since a stronger SGD makes exports more expensive to foreign buyers, reducing net exports, a component of aggregate demand (AD), and easing demand-pull pressure.
The stress test
Exchange rate appreciation carries significant trade-offs for a small, open, export-driven economy. Lower export competitiveness: a stronger SGD makes exports relatively more expensive abroad, reducing export demand and shifting AD leftward, which can lower real national income and slow growth. Rising unemployment: as export demand falls, export-oriented industries may reduce hiring, raising unemployment in sectors such as electronics, precision engineering and logistics. Inadequacy against severe cost shocks: a modest, gradual appreciation may be insufficient to counter large, sudden surges in global oil or food prices, so imported inflation may persist. And a worsening balance of trade: as export volumes fall while import demand stays stable or rises, the trade balance may deteriorate.
Supply-side measures
In addition to monetary policy, the government promotes supply-side strategies, such as encouraging firms to adopt technology and automation, often supported through grants and subsidies. This lowers long-run production costs, since automation and digitalisation help firms produce more output with the same or fewer inputs, raising productivity and shifting Long-Run Aggregate Supply (LRAS) rightward to expand productive capacity and reduce inflationary pressure. It also improves cost competitiveness, as lower unit costs reduce reliance on wage growth to drive output, helping contain cost-push inflation in a tight labour market.
The stress test
Supply-side policies present short- to medium-term challenges. Structural unemployment may rise as automation displaces low-skilled and routine jobs such as warehouse workers, clerks and service staff, if displaced workers cannot transition into higher-skilled roles. Skill mismatches and inequality can worsen, since demand for high-skilled workers rises faster than the supply can adjust, concentrating wage growth among higher-skilled individuals. And there is a time lag, as it takes time for technology adoption to translate into measurable productivity gains, so these policies are not well suited to addressing inflationary spikes in the short term.
Evaluative conclusion
Efforts to curb inflation in Singapore through currency appreciation and supply-side reform are well-targeted given the economy's openness and import dependence. However, both strategies come with important trade-offs. Exchange rate appreciation, while effective against inflation, can dampen export competitiveness, reduce growth and raise unemployment. Supply-side measures aimed at boosting productivity may cause structural unemployment and widen labour market inequality, especially in the short term. Policymakers must therefore strike a careful balance, containing inflation without undermining growth, equity and employment, by coordinating monetary, fiscal and structural policies to ensure overall macroeconomic stability.
