A majority of economists surveyed by Reuters expect Singapore's central bank to leave monetary policy unchanged at its scheduled review on July 27, judging that current inflation pressures remain too mild to justify further tightening despite an elevated Middle East conflict backdrop.

Twelve of 16 analysts polled expect the Monetary Authority of Singapore (MAS) to hold policy steady, while four anticipate additional tightening. The MAS last tightened in April this year, having left settings unchanged at its three previous reviews in January 2026 and in July and October 2025.

Unlike most central banks, the MAS manages monetary conditions through the Singapore dollar nominal effective exchange rate (SGD NEER), adjusting the slope, mid-point, and width of an undisclosed trading band rather than through direct interest rate changes. This exchange-rate-centered framework reflects Singapore's structure as one of the world's most trade-dependent economies, where import and export prices shape domestic inflation far more directly than domestic credit conditions, making the currency effectively the primary lever for price stability.

Inflation Within Forecast Range

Core and headline inflation stood at 1.6 percent and 1.9 percent respectively in June, according to official data released Thursday. Both figures fall comfortably within the MAS's official forecast range of 1.5 to 2.5 percent for core and headline inflation across 2026.

DBS senior economist Chua Han Teng said current policy settings remain well positioned to manage inflation risk, given that price growth is running low relative to the official forecast. Chua added that authorities will continue to closely monitor weather-related supply disruptions tied to El Niño and their potential impact on food inflation, a risk that sits alongside energy cost pressures stemming from the Middle East conflict as key inputs to the MAS decision.

Energy Costs and Middle East Tensions

The backdrop for the decision includes an escalating regional conflict. Yemen's Iran-aligned Houthi forces have imposed a naval blockade on Saudi Arabia, a development that risks tightening global energy supplies further. Despite that, Economist Intelligence Unit (EIU) Asia analyst Qi Hang Tay said he expects MAS to hold, noting that core inflation has stayed subdued and that the pass-through from higher energy costs has so far proven milder and less broad-based than anticipated.

Tay said an upward re-centring of the policy band would likely require a more severe inflation shock, such as prolonged disruption to regional energy supplies or another sharp jump in global oil prices, rather than the current level of Middle East disruption.

Underscoring the energy pressure, Singapore raised electricity tariffs by 17 percent for the third quarter due to soaring prices for imported natural gas, which accounts for 95 percent of the city-state's power generation. As an island nation with virtually no domestic energy resources, Singapore is particularly exposed to swings in regional liquefied natural gas markets, meaning that tariff adjustments serve as a visible gauge of how global energy disruptions translate into household and business costs.

Growth Case for Tightening

Not all economists agree that a hold is warranted. Oxford Economics senior economist Sheana Yue expects MAS to tighten by modestly steepening the SGD NEER slope, pointing to stronger-than-expected second-quarter economic growth as reinforcing the case.

Singapore's economy grew 5.7 percent year on year in the second quarter, driven by strong AI-related chip demand and coming in just above the 5.5 percent median forecast in a Reuters poll, according to preliminary government data. Yue said that growth performance, combined with the recent rise in oil prices following renewed Middle East tensions, points to a more inflationary outlook over coming quarters through both stronger domestic demand and higher imported costs.

Market Implications

The split view carries implications for the Singapore dollar. A hold would be seen as consistent with current pricing, while a surprise tightening, as the minority of analysts expect, could result in a modestly steeper SGD NEER slope and provide support for the currency. The stronger-than-forecast 5.7 percent second-quarter GDP print adds a genuine tightening argument, but with energy cost pass-through described as milder than expected so far, the bar for an upward re-centring of the band appears to require a more severe and sustained oil shock rather than the current level of Middle East disruption. Beyond the July 27 decision, market participants will be watching subsequent monthly inflation prints and any escalation in energy supply disruptions for signals on whether the MAS shifts stance at its next scheduled review.
