USD/SGD measures how many Singapore dollars one US dollar buys. Singapore's currency is central to its role as a regional trade and financial hub, and the pair is closely watched by businesses moving goods and capital through the city-state.
The Singapore dollar operates under a distinctive framework. Rather than setting interest rates, the Monetary Authority of Singapore (MAS) manages the SGD against an undisclosed trade-weighted basket of currencies of its major trading partners — known as the S$NEER — keeping it within a policy band that MAS can adjust in slope, width, and center. This makes exchange-rate policy, not interest-rate policy, the primary lever of Singapore's monetary policy.
Because the basket composition is not published, USD/SGD moves reflect a mix of the basket's implied path, Singapore's trade and financial flows, and broader regional risk sentiment, rather than a simple read on US-Singapore rate differentials alone.
This page shows an indicative mid-market USD/SGD rate that can update intraday through the trading week. Every API response carries a source and market_session field, so you can always tell whether a given quote was a live tick or a daily fix. Rates are indicative only, not for settlement or regulated trading.
Frequently asked questions
What does USD/SGD measure?
USD/SGD states how many Singapore dollars you receive for one US dollar. A rate of 1.34 means one dollar buys 1.34 SGD.
Is USD/SGD a live rate on exchangerate.dev?
USD/SGD is served as an indicative mid-market rate that can update intraday through the trading week. Check the source and market_session fields on each API response to see whether a specific quote was a live tick or a daily reference fix — exchangerate.dev never promises a fixed refresh interval.
How do I get the USD/SGD rate via the API?
GET /v1/latest/USD?symbols=SGD returns the indicative rate along with source, market_session, and timestamp. The reverse (SGD as base) is also supported. The free tier covers it, no credit card required.
Why doesn't Singapore set interest rates like other countries?
The Monetary Authority of Singapore uses the exchange rate itself, not the interest rate, as its main monetary policy tool. It manages the SGD against an undisclosed basket of trading-partner currencies within a policy band, adjusting the band's slope, width, or center as conditions change.
What is the S$NEER?
S$NEER stands for the Singapore Dollar Nominal Effective Exchange Rate — a trade-weighted basket MAS uses internally to guide the SGD. The exact currency weights are not published, so market participants estimate the basket's implied path rather than observe it directly.
Why does USD/SGD react to regional risk sentiment?
Singapore is a major regional financial and trade hub, so capital flows tied to broader Asian risk appetite pass through its markets. Shifts in regional sentiment can move the SGD even when there is no news specific to Singapore itself.
Is USD/SGD suitable for settlement or trading decisions?
No. exchangerate.dev provides indicative rates for reference and informational use only — not for settlement, regulated trading, or as a source-of-record price.
