Rates are indicative. They come from the European Central Bank via Frankfurter.app, or from an independent backup feed (open.er-api.com) when that is unreachable. They may differ from rates offered by banks, money changers, or remittance services. Not financial advice.
How to Use the Currency Converter
Enter the amount
Type any number into the amount field. Default is 1 for quick rate checking. You can enter decimals or large numbers — the converter handles any value.
Select currencies
Choose your source currency from the From dropdown and your target in To. Currencies are grouped: those with a live quote sit at the top, under a heading that shows exactly how many there are right now, and the rest are listed below for reference. Pick one of those and the tool tells you plainly that no live quote is available rather than showing a stale number. Coverage moves with whichever upstream feed is answering — the ECB set is the majors, G10 and the larger ASEAN currencies, while the backup feed reaches almost the whole list — so read the heading rather than assuming.
Click Convert or pick a quick pair
Hit the orange Convert button, or click any of the popular SGD pairs below for instant ASEAN conversions. The result shows the converted amount, the unit rate, and when the rates were last updated.
Tap ⇄ to reverse
Click the swap arrow to instantly flip the conversion direction — handy for checking rates both ways when comparing what you get going and coming back from a trip.
Currency Exchange in Southeast Asia — What Every Traveller and Investor Should Know
Why Exchange Rates Change Every Minute
Currency exchange rates are not set by a single authority — they float continuously based on the buying and selling pressure of millions of participants in the global foreign exchange (forex) market. Every time a company repatriates profits, a central bank adjusts its reserves, or a fund manager shifts capital between countries, the rate moves.
In Southeast Asia, two central banks play outsized roles in managing their currencies. The Monetary Authority of Singapore (MAS) operates a unique managed float regime — rather than targeting an interest rate like most central banks, MAS manages the Singapore dollar (SGD) against a trade-weighted basket of currencies within an undisclosed policy band. This makes the SGD one of Asia's most stable currencies. By contrast, Bank Negara Malaysia (BNM) has intervened multiple times in the ringgit market to stem volatility — most famously during the 1997–98 Asian Financial Crisis, when Malaysia imposed capital controls and pegged the MYR at 3.80 to the USD.
The rate you see on any currency converter — including this one — is the mid-market rate (also called the interbank rate). It is the midpoint between the rate at which banks buy and sell currency, and is updated throughout the trading day. You will rarely receive this exact rate as a consumer; banks and money changers add a spread on top of it to make their profit.
The hidden cost of converting
What you pay is the difference between the mid-market rate and the rate you are actually given — the spread — plus any fee on top. A bank or money changer never deals at the mid-market rate: it buys currency from you a little below it and sells a little above it. Even Bank Negara Malaysia's own published rates show the gap: on 14 October 2026 it quoted RM3.1656 buying and RM3.2076 selling per Singapore dollar, about 1.3% apart.
Spreads differ by provider, by currency and by day, so the useful comparison is the amount you would actually receive for your amount, set against the mid-market figure above. If the mid-market rate is 3.19 and a counter offers 3.10, you are giving up about 2.8% — whatever the board says about fees.
Card terminals abroad sometimes offer to charge you in Singapore dollars instead of the local currency. That is Dynamic Currency Conversion: the rate is set by the merchant's payment provider rather than by your card network. You can decline it and pay in the local currency, then compare both against the rate here.
When the rate moves
The interbank FX market trades around the clock from the Monday open in Asia-Pacific to the New York close on Friday. It is deepest when London and New York overlap — roughly 8 pm to midnight Singapore time, an hour later in the northern winter. The rates on this page are the European Central Bank's reference rates, set once each European business day, so they do not move during the day.
Scheduled announcements move the SGD/MYR pair. MAS has issued its monetary policy statement four times a year since 2024 — in January, April, July and October — and Bank Negara Malaysia's Monetary Policy Committee meets several times a year.
One Singapore dollar averaged RM2.36 in 2010 and fetched RM3.19 on 13 October 2026 — about 35% more ringgit, by the ECB's reference rates.
For Singaporeans with family, savings or plans in Malaysia, that is the practical meaning of the trend: each Singapore dollar buys considerably more ringgit than it did in 2010. The path was not smooth — the rate peaked at 3.11 on 29 September 2015 before falling back — so the rate on the day you convert still matters.
A ringgit fixed at 3.80, and two dollars exchanged at par
The Singapore dollar is run as a managed float: MAS manages it against a trade-weighted basket of currencies within an undisclosed policy band, rather than setting an interest rate.
Malaysia fixed the ringgit at RM3.80 to the US dollar on 2 September 1998, the day after imposing selective exchange controls, and moved to a managed float on 21 July 2005.
One Singapore dollar bought 13,971 rupiah on 13 October 2026 at the ECB reference rate — the largest per-dollar figure among the currencies this tool quotes live.
FX trading averaged US$9.6 trillion a day in April 2025, up 28% from 2022, according to the BIS Triennial Survey.
Singapore is the world's third-largest FX centre, after the UK and the US: US$1.485 trillion a day in April 2025, 11.8% of global turnover (MAS).
Under the 1967 Currency Interchangeability Agreement, Brunei and Singapore notes are exchanged at par. In each other's country they are customary tender, not legal tender: banks must exchange them, shops need not accept them.
The US dollar was on one side of 89% of all FX trades in April 2025 (BIS).
The ECB publishes reference rates for about 30 currencies. The Vietnamese dong and the Brunei dollar are not among them, so this tool quotes them only when its backup feed is answering.
SGD/MYR averaged 2.36 in 2010 and peaked at 3.11 on 29 September 2015, by the ECB's reference rates.
The mid-market rate is the midpoint between buying and selling prices in the wholesale market. Consumers rarely get it — always ask for the amount you will actually receive.
Frequently Asked Questions
-
The mid-market rate (also called the interbank rate or spot rate) is the midpoint between the buy and sell prices in the wholesale currency market. It is the rate that banks use when trading with each other and the benchmark shown on Google, XE, and currency converters like this one. Retail consumers — individuals and small businesses — typically receive a worse rate because banks and money changers add a spread to make their profit. The gap between the mid-market rate and what you actually get is the hidden cost of currency conversion.
-
This tool shows the mid-market rate — the theoretical fair rate with no markup. Your bank quotes its own buying and selling rates either side of it — the spread is its margin. They may also charge a flat transaction fee or a service charge. The rate shown here is a reference point for comparison; always check the all-in rate (including all fees) when deciding where to exchange currency. For better rates, compare independent money changers, digital platforms like Wise, and your bank before transacting.
-
Rates are fetched first from the Frankfurter API, which is sourced from the European Central Bank (ECB) and updated daily on business days. If that is unreachable we use an independent backup feed (open.er-api.com), which covers many more currencies, and failing both we serve the last good response for up to seven days. Your browser caches the rates for up to 60 minutes per session so conversions are instant without repeated API calls, and the “Rates updated” timestamp in the result box shows when the current data was fetched. If every source is down the tool shows an amber warning and converts nothing: there is deliberately no stored rate table to fall back on, because a stale rate is indistinguishable from a current one.
-
Singapore dollars are widely exchanged in Malaysia, and you can also change them before you leave. Rates differ between counters on both sides of the Causeway, so compare the ringgit you would actually receive, against the mid-market rate here, before changing a large amount. Withdrawing ringgit at a Malaysian ATM with a card that has low foreign-transaction charges is another option; check both the card's rate and any ATM fee.
-
Online currency converters — including this one — are useful for reference and planning, but should not be used as the sole basis for financial decisions. The rates shown are indicative mid-market rates that you will not receive in a real transaction. For large currency exchanges (property purchases, business payments, large remittances), always get a firm quote from your bank or broker and factor in all fees. For everyday travel or small purchases, a currency converter gives you a reliable benchmark.
-
By the European Central Bank's reference rates, one Singapore dollar averaged RM2.36 in 2010 and fetched RM3.19 on 13 October 2026 — about 35% more ringgit. The rise was not steady: the rate peaked at 3.11 on 29 September 2015, when the ringgit fell with oil prices, and came back down before climbing again. Bank Negara Malaysia and MAS both publish historical exchange rates.
-
Airport money changers operate in a captive market — you have limited alternatives and often limited time. They pay airport rents, face fewer competitors than city-centre operators, and serve travellers who have not pre-planned their currency exchange — conditions that let a counter quote a wider spread than it could in the city. As a rule, exchange just enough at the airport to cover your first taxi or meal, then use a city money changer or ATM for the rest.
-
Unlike most central banks that set interest rates, MAS manages monetary policy through the exchange rate. The SGD is allowed to float within an undisclosed band against a trade-weighted basket of currencies from Singapore's main trading partners. MAS sets three parameters — the mid-point of the band, the width of the band, and the slope (rate of appreciation). When the SGD approaches the edges of the band, MAS intervenes by buying or selling SGD. MAS has announced its policy four times a year since 2024 — January, April, July and October — describing changes in general terms rather than numbers (for example, a "modest and gradual" rate of appreciation).
-
There is no official ranking for retail money changers: MAS publishes wholesale FX turnover, not counter-by-counter volumes. In the wholesale market Singapore handled US$1.485 trillion a day in April 2025, and worldwide the US dollar was on one side of 89% of all trades (BIS).
-
No — this tool covers traditional (fiat) currencies only. Cryptocurrencies such as Bitcoin (BTC), Ethereum (ETH), and stablecoins are not included. Crypto prices change by the second and are sourced from different markets with different structures. For crypto conversions, use a dedicated crypto price tracker. On the fiat side the tool lists 147 ISO 4217 currencies, including every ASEAN currency. How many of those carry a live quote depends on which upstream feed is answering at the time, so the picker groups them and shows the current count; anything outside that group returns “no quote” rather than a stale number.
Method & sources
What this tool implements
- No rates ship with the page. A bundled table is the classic failure of a currency converter — it keeps returning confident numbers years after anyone stopped updating it. This tool cannot do that, because it has nothing to fall back on except a dated cache it labels.
- The browser never contacts a foreign-exchange provider. Requests go to a first-party endpoint which fetches server-side, so no reader's IP is handed to a third party to convert a number.
- When every provider and the cache are exhausted the endpoint returns an error and the tool says so. A converter that guesses is worse than one that stops.
- Decimals follow ISO 4217 list one (published 2026-09-17): no minor unit for BIF, CLP, DJF, GNF, ISK, JPY, KMF, KRW, PYG, RWF, UGX, UYI, VND, VUV, XAF, XOF, XPF; three for BHD, IQD, JOD, KWD, LYD, OMR, TND. IDR, KHR, LAK and a few others have a two-digit minor unit in ISO that is not used in practice and are shown with none — a display choice, stated as one.
- Every figure in the page's prose is dated and sourced: ECB reference rates for SGD/MYR (2010 average 2.3624, peak 3.1139 on 29 Sep 2015, 3.1925 on 13 Oct 2026) and SGD/IDR; BIS and MAS for turnover; MAS for the policy calendar and the Brunei agreement; Bank Negara Malaysia for the 1998–2005 fixing and its 14 Oct 2026 published buying and selling rates. Spread percentages without a source were removed rather than kept as "typical".
- Corrected 2026-10-14: SGD/MYR given as 3.48 and "+46% since 2010" (actual 3.19, +35%); FX turnover and Singapore's share from the 2022 survey; MAS policy "twice a year" (quarterly since 2024); Brunei and Singapore notes called legal tender in both countries (they are customary tender); JPY and KRW shown with decimals ISO does not give them.

What can make this go out of date
- Two live third-party APIs, in priority order, behind a first-party proxy. Neither requires a key, and both can go down; the endpoint keeps the last good response as a lifeline and marks it stale rather than pretending it is current.
- ⚠️ The ECB set is about 30 currencies (29 besides SGD on 2026-10-13). A currency outside it — the Vietnamese dong and the Brunei dollar among them — has a quote only while the backup feed is answering.
- ECB does not publish on weekends or on TARGET holidays. Friday's rate is served through the weekend, correctly labelled with its own date.
