Central bank raises the slope of its currency band as Middle East tensions drive up imported cost pressures

Singapore has tightened monetary policy in response to rising inflation risks linked to the Middle East conflict, becoming the first central bank in Asia to make such a move as higher energy costs begin feeding into import prices and broader cost pressures. MAS said it increased the slope of its exchange-rate policy band while keeping the width and center unchanged.

MAS Tightens by Adjusting the Policy Band
The Monetary Authority of Singapore said it would increase the slope of its policy band, a move that effectively allows for a stronger Singapore dollar path to help contain imported inflation. MAS does not use interest rates as its main tool, unlike many central banks, and instead manages policy through the exchange rate. The decision was widely expected by economists surveyed by Bloomberg.

Higher Energy Costs Are Driving the Shift
MAS said imported energy costs have already risen and warned that oil prices are likely to stay elevated for some time even if Middle East supply conditions improve. It added that as higher energy costs pass through global supply chains, a broader range of Singapore’s import costs will increase, raising the risk of more persistent inflation pressure in the domestic economy.

Inflation Forecast Has Been Revised Up
Alongside the policy move, MAS raised its core inflation forecast for 2026 to 1.5 percent to 2.5 percent, up from the earlier 1 percent to 2 percent range. Bloomberg reported that the central bank also warned higher prices could erode real incomes and weaken demand in the quarters ahead, showing the authorities now see inflation risk as more urgent than before.

Growth Is Still Holding, But Risks Are Rising
Singapore’s economy shrank 0.3 percent quarter on quarter in the first three months of 2026, according to advance estimates, though it still expanded 4.6 percent year on year. Manufacturing saw a sharp quarterly drop of 4.9 percent after earlier strength linked to AI-led demand. The Ministry of Trade and Industry said the US-Israel-Iran conflict, which began in late February, may weigh on activity in the coming quarters, and it will update the growth forecast in May.

Markets Are Watching for Another Move
Analysts quoted by Bloomberg said MAS may be leaving the door open for another tightening step in July if inflation keeps rising and growth stays resilient enough. The central bank also said it stands ready to curb excessive volatility in the S$NEER, signaling that exchange-rate stability will remain an important part of its response as geopolitical shocks continue to affect global markets.

Singapore’s latest move shows how quickly imported inflation can become a policy priority for an open economy that depends heavily on global trade and energy flows. For Singaporeans, the tighter stance is meant to protect purchasing power, but it also reflects the expectation of a more expensive period ahead. For Indonesians and other regional observers, the decision underlines how the Middle East conflict is already reshaping economic policy choices across Asia, even in countries far from the battlefield.
