U.S. Dollar / Singapore Dollar

Tuesday Morning: The Calm Before the Storm

Tuesday 28.07.2026 began across Asian currency markets with the kind of unusual silence that typically precedes major events. Most regional currencies traded within narrow ranges, as though holding their breath ahead of the US Federal Reserve meeting scheduled for Wednesday. Meanwhile, the US dollar remained close to a one-month high, creating tension that could be felt in every movement of the exchange rates.

The US Dollar Index fell by 0.1% to 101.46. The decline was barely noticeable, but it highlighted the market’s indecision. Investors were reluctant to open new positions, preferring to wait for signals from the Fed. Even the decline in oil prices, which normally reduces inflation concerns and may put pressure on the dollar, failed to move the market out of its standstill. Traders remained frozen in anticipation.

Markets currently estimate the probability of a 25-basis-point Fed rate increase on Wednesday at approximately 38%. This is not the dominant scenario, but the probability is high enough to make investors cautious. Should the Fed raise rates, the decision could surprise many market participants and trigger sharp movements across global markets. Should rates remain unchanged, attention will shift to comments from Chair Kevin Warsh, who may provide signals regarding the future direction of monetary policy.

Additional uncertainty comes from the upcoming US GDP and core PCE inflation data, which are also scheduled for release this week. These indicators may provide further guidance on monetary policy and influence investor expectations.

Unlike almost every other major central bank that uses interest rates to manage monetary conditions, Singapore’s Monetary Authority of Singapore (MAS) controls its economy through the exchange rate. Because Singapore imports almost everything it consumes, domestic price stability is directly tied to the strength of the Singapore Dollar (SGD).

For Forex traders, USDSGD ... offers a unique setup where microeconomic fundamentals take a back seat to central bank policy band mechanics and Asian trade flows.

The MAS Framework: Baskets, Bands, and Crawls

The MAS manages the Singapore Dollar using an exchange-rate-based framework built on the S$NEER (Singapore Dollar Nominal Effective Exchange Rate).

Instead of targeting a single currency, MAS pegs SGD against an undisclosed trade-weighted basket of its major trading partners' currencies.

• Slope: The rate of appreciation or depreciation of the band over time. A steeper slope signals tightening to fight imported inflation; a flat slope indicates neutral policy.

• Width: The floor and ceiling range (typically estimated at $pm2%$) around the policy midpoint.

• Midpoint: Re-centering the band up or down during sharp macroeconomic shocks.

Primary Price Drivers for USD/SGD

1. Fed vs. MAS Policy Divergence

While the Federal Reserve adjusts the Fed Funds rate, the MAS alters the slope, width, or center of the S$NEER band. When the Fed holds rates steady while MAS increases its appreciation slope, USD/SGD faces structural downward pressure.

2. China & Regional Trade Proxy

Singapore is a global financial and trade hub. Consequently, the Singapore Dollar functions as a high-liquidity proxy for regional Asian growth and trade volumes. USD/SGD shares a strong positive correlation with USD/CNH (+0.71 to +0.78). When Chinese economic performance accelerates, capital flows into Asian trade networks, typically strengthening SGD against USD.

3. Dual Safe-Haven Dynamics

Both currencies possess safe-haven attributes, but under different circumstances:

• USD: Global risk-off sentiment (geopolitical crises, liquidity squeezes).

• ...
