USD to SGD in August 2026: high, low, average

Updated September 26, 2026

The US dollar averaged 1.2763 Singapore dollars in August 2026, calculated from 21 ECB fixings. The Singapore dollar gained steadily through the month: the rate started at 1.2816, peaked at 1.2824 on August 4, and fell to a low of 1.2683 on August 21. It closed August at 1.2727, 0.69% below the first fixing.

The month's key rates

A managed currency that still moves

Singapore runs its monetary policy through the exchange rate. The Monetary Authority of Singapore steers the Singapore dollar against a basket of currencies of its trading partners, allowing it to move within an undisclosed band. Against the US dollar alone, that still leaves room for months like this one.

In the first two weeks the dollar drifted lower in small steps, from 1.2824 to 1.2781 on August 14. Moves of a tenth of a percent in either direction were typical. The pace picked up on August 20 and 21, with falls of 0.32% and 0.3%, which took the rate to the monthly low. The last week recovered part of that ground, with the largest gain of the month, 0.17%, on August 24.

In all, the dollar fell on 12 fixings and rose on 8.

How August compares

The August average was 1.18% lower than July, when it stood at 1.2916. It was also 0.73% lower than in August 2025, when one dollar bought 1.2857 Singapore dollars. The Singapore dollar is stronger against the US dollar than it was both a month and a year earlier.

What a stronger Singapore dollar means

Companies with regional headquarters in Singapore. Many multinationals run Asian operations from Singapore and report in US dollars. Costs in Singapore, such as salaries and rent, look higher in dollar terms when the local currency strengthens.

Singapore residents spending in dollars. Holidays in the United States, online purchases priced in dollars, and US share investments all became cheaper in Singapore dollar terms over the month. At the monthly average, one Singapore dollar bought 0.78354 US dollars.

Exporters. Singapore's exporters of electronics, chemicals and services earn in US dollars. A lower USD/SGD rate reduces the Singapore dollar value of that revenue.

Using the rate for bookkeeping

For companies closing their books in Singapore dollars, the ECB-based average for the month is 1.2763 and the closing rate is 1.2727. Local accounting often follows the rates published by the Monetary Authority of Singapore or by the company's bank, so check which source your policy names.

One practical note for small businesses: when a Singapore supplier invoices in Singapore dollars and a US customer pays in dollars, agree in the contract which day's rate applies. A difference of 1.11%, the range of August, can decide who absorbs a noticeable part of the margin.
