Causes of Singapore's 2017 Inflation and Policies to Maintain Price Stability
Answer
Part (a) — How the three factors raise inflation [10]
Inflation is a sustained rise in the general price level. The three factors named act through different channels — one demand-pull, two cost-push.
High speculative buying in the housing market (demand-pull). Speculative demand for housing is an autonomous rise in consumption (C), a component of aggregate demand. With the economy near full employment, the rightward shift of AD raises the general price level — demand-pull inflation.
A tight domestic labour market (cost-push). A tight labour market puts upward pressure on wages. Higher wages raise firms’ unit costs of production, shifting short-run aggregate supply leftward and raising the price level — cost-push inflation.
Rising global oil prices (imported cost-push). Singapore lacks crude oil and imports it. A rise in the world oil price raises the cost of imported inputs, again raising unit costs and shifting aggregate supply leftward — imported cost-push inflation. The combination of one demand-pull and two cost-push forces lifts the price level on both blades of the scissors.
Part (b) — Policies to maintain price stability [15]
Because the 2017 inflation is both demand-pull and cost-push, no single instrument addresses it fully; the policies must be assessed against the specific cause each targets, and the judgement is that a mix is required, anchored on the exchange rate.
Exchange-rate policy — modest SGD appreciation. Singapore’s primary anti-inflation tool is its exchange-rate-centred monetary policy. A gradual, modest appreciation of the SGD lowers the domestic-currency cost of imported raw materials and oil, raising short-run aggregate supply and directly attacking the imported cost-push component. It also restrains aggregate demand: provided the Marshall–Lerner condition holds (), appreciation reduces net exports (X − M), shifting AD leftward and easing the demand-pull component. This is well-suited to Singapore as a small, import-dependent, trade-reliant economy — the chief limitation is that a too-rapid appreciation would erode export price competitiveness and harm growth.
Supply-side policies. Subsidies can offset the higher input and labour costs, raising short-run aggregate supply; longer-term measures — incentives for innovation and skills upgrading — raise long-run aggregate supply and deliver non-inflationary capacity. These tackle the cost-push roots at source. Their limitations are the strain subsidies place on the government budget and the long time lags before LRAS-raising measures bite — so they cannot deliver price stability within 2017 alone.
Contractionary fiscal policy. Cutting government spending and/or raising taxes lowers G and, via reduced disposable income, C — shifting AD leftward and easing demand-pull inflation. This directly addresses the speculative-housing channel (and could be sharpened with targeted property cooling measures). The limitation is the conflict with other macroeconomic aims: dampening AD also slows growth and raises unemployment.
Judgement. No single policy is sufficient because the inflation is multi-causal. Demand-side tools (appreciation, contractionary fiscal policy) address the speculative-demand component but do nothing for, and can worsen, the cost side; supply-side tools address costs but act slowly. The most appropriate response is therefore a mix centred on a modest SGD appreciation — which uniquely hits both the imported-cost and the net-export channels at once — supported by targeted measures against housing speculation and supply-side measures for the labour and energy cost pressures. The exchange rate does the heavy lifting precisely because Singapore’s openness makes imported inflation the dominant and most directly addressable channel.
