MAS Tightens Again as Oil Shock Threatens Inflation

Singapore, a small and highly open economy, relies on the exchange rate rather than interest rates as its main monetary-policy lever. The Monetary Authority of Singapore manages the Singapore dollar nominal effective exchange rate, or S$NEER, against a basket of trading-partner currencies. A steeper appreciation slope strengthens the currency over time, helping curb the local cost of imported fuel, food and other goods as an external energy shock spreads through freight, production and consumer prices.

On July 27, 2026, MAS raised the S$NEER policy band’s appreciation rate “very slightly,” its second consecutive tightening and a smaller move than on April 14. The band’s width and midpoint were unchanged. Singapore’s economy grew 5.7% from a year earlier in the second quarter, while June core and headline inflation were 1.6% and 1.9%, respectively. MAS retained its 2026 forecasts of 1.5% to 2.5% for both measures and expects core inflation to rise from July.
