Introduction
The COVID-19 pandemic caused a sharp downturn in Singapore, with GDP growth forecast between negative 4% and negative 1% for 2020 (Macroeconomic Review, April 2020, MAS). The recession stemmed from combined demand and supply shocks: plummeting consumer and tourist demand, global supply chain disruptions and falling business investment. In response, the Monetary Authority of Singapore and the government deployed different tools, monetary policy centred on the exchange rate and large-scale discretionary fiscal policy.
Exchange rate-based monetary policy in Singapore
Unlike most countries that rely on interest rate adjustments, Singapore adopts an exchange rate-based monetary policy because of its highly open, trade-dependent economy. MAS manages the Singapore dollar against a trade-weighted basket of currencies using a band, basket and crawl framework, allowing the currency to move within an undisclosed policy band.
During high inflation MAS typically allows modest and gradual appreciation to reduce imported inflation. In recessionary periods such as the pandemic, MAS moved to a zero percent appreciation stance to avoid further pressure on exporters and support stability. This neutral stance was appropriate: there was no inflation to suppress, and in fact deflationary pressures were mounting from collapsing demand and oil prices; continued appreciation would have further reduced export competitiveness in sectors like manufacturing and logistics; and deliberate depreciation was not viable because Singapore relies heavily on imported inputs, so a weaker currency would have raised costs of production and risked cost-push inflation without a corresponding export boost. MAS's stance therefore helped prevent the recession from worsening, but it was a stabilising measure rather than one that could actively stimulate demand or generate recovery.
Discretionary fiscal policy and its role in recovery
Given the limits of monetary policy in this crisis, discretionary fiscal policy became the central tool. It involves deliberate increases in government spending and transfers to directly boost aggregate demand. The government rolled out multiple stimulus packages in 2020 totalling nearly S$100 billion, including the Jobs Support Scheme, which subsidised a portion of employee wages to reduce retrenchment; direct public sector hiring such as Safe Distancing Ambassadors and healthcare support roles; bringing forward infrastructure spending on transport and construction; and cash transfers and rental relief for households and small businesses.
These interventions raised government spending, shifting AD rightward, increasing real national income and reducing cyclical unemployment, which mattered given the scale of job losses in tourism, aviation and retail. However, fiscal policy has limitations. Leakages, especially Singapore's high marginal propensity to save and to import, mean the multiplier may be smaller than in more closed economies, reducing the impact on GDP. There is a potential inflation trade-off if stimulus is too large as the economy nears full employment, especially in capacity-constrained sectors like construction. Not all sectors benefited equally; aviation and tourism, hit by border closures, could not recover simply from increased spending elsewhere, as their recovery depended on global reopening outside the government's control.
Evaluative conclusion
While exchange rate policy cushioned the recession and stabilised the external sector by avoiding export-damaging appreciation or inflation-inducing depreciation, it was not designed to actively stimulate aggregate demand. Discretionary fiscal policy, by contrast, was essential in providing immediate, large-scale support to households and businesses, directly addressing the sharp fall in consumption and investment. For a demand-and-supply shock of this nature, fiscal intervention was the more effective tool for driving recovery, with exchange rate policy playing a necessary supporting, stabilising role.
