Exchange Rates on 31 December 2025 for Singapore: MAS Closing Rates and Year Averages

A 31 December year-end needs a closing rate for every foreign currency balance. The Monetary Authority of Singapore (MAS) released a table on 31 December 2025, the last of the year. This page sets it out in the form MAS uses, with the averages that the income statement and the tax return need.

MAS rates on 31 December 2025

MAS quotes only the US dollar, euro and sterling per one unit. Every other currency, including the Australian, Canadian and New Zealand dollars and the Swiss franc, is per 100 units. Keying 85.97 into a system that expects a per-unit rate is the most common loading error with this table.

MAS describes the figures as the average of buying and selling interbank rates quoted around midday in Singapore; daily figures are values as of noon, released at 3 pm on each business day.

Averages

The first row is MAS's own figure. The other two are computed from the MAS daily table. The month-end average is the method IRAS prescribes for companies filing in a non-Singapore dollar functional currency; see the corporate tax guide.

The accounting rule

Singapore's standard on foreign exchange is SFRS(I) 1-21, The Effects of Changes in Foreign Exchange Rates, within a framework ACRA describes as equivalent to IFRS Accounting Standards. Under IAS 21:

• a foreign currency transaction is recorded at the spot rate on the date of the transaction;
• foreign currency monetary items are translated at the closing rate, the spot rate at the end of the reporting period;
• a rate that approximates the actual rate, such as an average for a week or a month, may be used unless rates fluctuate significantly.

The standard names no rate source. Choose one, document it and apply it each period. Read the SFRS(I) 1-21 text itself before quoting it in a policy document.

The API returns every MAS rate per one unit of the foreign currency, so the yen appears as 0.008204 and the renminbi as 0.1837. Multiply by 100 to match the MAS display. The response carries requested_date and rate_date; for a year-end that falls on a weekend, rate_date shows the earlier table returned. Dated tables and history are on paid plans.
