Singapore’s Monetary Authority of Singapore (MAS) said on July 27 that it would tighten monetary policy slightly by increasing the appreciation slope of the Singapore dollar nominal effective exchange rate, or S$NEER, policy band. The move marked a second consecutive tightening after April, although the latest adjustment was smaller. The width and midpoint of the policy band were left unchanged.
The decision came as a mild surprise. A Reuters survey conducted before the announcement had shown that most analysts expected MAS to keep policy unchanged.
MAS uses the exchange rate, not interest rates
MAS operates differently from the U.S. Federal Reserve and the European Central Bank, which mainly adjust interest rates. In Singapore, monetary policy is implemented through management of the Singapore dollar against a basket of trade-weighted currencies.
By steepening the appreciation slope, MAS is allowing the Singapore dollar to rise at a faster pace over time. The mechanism is aimed at lowering import costs and containing imported inflation.
That framework reflects Singapore’s position as a highly open, small economy where domestic prices are heavily influenced by imported energy costs.
Oil-price risks and power costs were in focus
The market viewed the latest tightening as a pre-emptive step against rising oil-price risks. Geopolitical tensions in the Middle East had at one point pushed up crude oil and natural gas prices. Singapore’s electricity tariffs for the third quarter were also raised because of higher imported natural gas costs.
Even so, local inflation remained within a manageable range. June core inflation stood at 1.6%, while headline inflation was 1.9%. Both figures were within the official 2026 forecast range of 1.5% to 2.5%.
GDP growth added support
Economic growth also supported the policy decision. Singapore’s second-quarter GDP expanded 5.7% year on year, above market expectations. MAS described the move as a cautious calibration that extends the tightening stance adopted in April, at a time of greater uncertainty.
