USDSGD definition

USD/SGD is the exchange rate between the US dollar and the Singapore dollar, showing how many Singapore dollars one US dollar will buy. It is a minor pair, at about 2.2% of the roughly $9.6 trillion that changes hands in the global forex market each day (BIS Triennial Survey, 2025), with reasonable liquidity but wider spreads than the headline majors.

The US dollar is the base currency and the Singapore dollar the quote currency, so a quote of 1.3500 means one US dollar is worth 1.3500 Singapore dollars. A rising price means the US dollar is strengthening against the Singapore dollar, a falling price the reverse. You trade USD/SGD as a forex CFD, taking a view on the price rather than buying Singapore dollars outright: go long if you expect the US dollar to rise, short if you expect it to fall. Pips are the fourth decimal place, and your result is the pips gained or lost multiplied by your position size, settled in Singapore dollars.

What sets this pair apart is how Singapore runs monetary policy. Rather than setting an interest rate, the Monetary Authority of Singapore manages the Singapore dollar against an undisclosed trade-weighted band of partner currencies, adjusting the band's slope and width to control imported inflation. That makes the pair more about MAS policy settings and regional trade flows than about a domestic rate decision, so it tends to move in steadier, policy-guided ranges.
