The Monetary Authority of Singapore's current policy stance is a key factor behind the Singapore dollar's relative resilience against other Asian currencies, according to a recent analysis by MUFG Bank.

As of early 2025, the Singapore dollar, or SGD, has held a comparatively stable path against the U.S. dollar, while several other regional currencies have seen more pronounced volatility. MUFG's assessment points to the MAS's exchange rate-centered monetary policy framework as an important source of support for the currency. Singapore's position as a small, highly open economy — where total trade exceeds several times its GDP — makes the exchange rate a more effective lever for managing inflation than a domestic interest rate, which is why the MAS adopted this unconventional framework in the first place.

MAS Uses an Exchange Rate-Based Framework

Unlike most central banks, which primarily conduct monetary policy by adjusting interest rates, the MAS manages policy through the Singapore dollar nominal effective exchange rate, known as the S$NEER. The central bank sets the slope, width and center of the S$NEER policy band, directly targeting the trade-weighted value of the currency. The MAS reviews this band twice a year, in April and October, providing scheduled opportunities to recalibrate in response to shifting conditions.

MUFG analysts said the MAS's decision to keep a slightly appreciating slope for the policy band, even as global inflation pressures ease, indicates a continued focus on price stability. That approach, they said, has helped reinforce investor confidence in the Singapore dollar.

The framework differs from conventional interest rate policy because it uses the exchange rate as the main tool to manage inflation and support economic growth. By setting the Singapore dollar against a basket of currencies through the S$NEER band, the MAS directly influences the currency's value rather than relying on a domestic policy rate.

Regional Currency Performance Highlights SGD Stability

The Singapore dollar's resilience is more visible when compared with regional peers such as the Japanese yen, South Korean won and Thai baht. Those currencies have faced sharper depreciations, reflecting divergent monetary policy paths as well as domestic economic challenges.

According to MUFG's analysis, the MAS's proactive policy approach has helped cushion the SGD against external pressures. The bank cited the MAS's recent tightening cycle, which ended later than those of some regional central banks, as one factor that has provided a buffer against shocks including persistent U.S. dollar strength and geopolitical uncertainty in the region.

The Singapore dollar is considered resilient in part because the MAS maintains a credible policy framework with a slightly appreciating bias for the currency. That stance helps anchor inflation expectations and limits the impact of external volatility, contributing to a more stable exchange rate than many regional counterparts.

Effects on Businesses and Investors

For companies operating in Singapore or trading with the country, a relatively stable SGD can reduce currency risk, supporting longer-term investment planning and cost management. Importers may benefit from less volatile input prices, while exporters may face the challenge of a somewhat stronger currency but gain from greater overall predictability.

For investors, MUFG said the Singapore dollar's resilience supports the appeal of Singaporean assets, including bonds and real estate, as a safe haven within Asian markets. Such demand could potentially attract capital inflows that provide additional support for the currency.

A resilient Singapore dollar also helps contain imported inflation, contributing to more stable consumer prices. It can create a more predictable environment for trade and investment and strengthen business confidence, although it may also make Singapore's exports slightly more expensive and affect competitiveness in price-sensitive markets.

MAS Framework Remains Central to Currency Strength

MUFG's analysis reinforces the view that the MAS's disciplined and transparent monetary policy framework remains a cornerstone of the Singapore dollar's strength.

Although external headwinds remain, including global monetary tightening and trade tensions, the MAS's commitment to an exchange rate-centered policy is expected to continue providing a stabilizing influence. That stance has helped make the SGD one of the more resilient currencies in the current regional landscape.
