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 Currency Conversion in ASEAN

When you exchange currency, you pay more than just the rate. The difference between the mid-market rate and the rate you actually receive is called the spread — and it is the hidden fee that most people never notice. A typical bank in Singapore might offer SGD/MYR at 3.38 when the mid-market rate is 3.48, effectively charging you a 2.9% fee without disclosing it as a fee.

Airport money changers are notorious for offering the worst rates in any city. At Changi Airport, the spread on SGD/MYR can run 4–6% above the mid-market rate. Independent money changers on Singapore's People's Park Complex or Golden Mile Complex typically offer rates within 0.5% of the interbank rate — among the best in Asia.

A particularly costly trap for travellers is Dynamic Currency Conversion (DCC) — when a payment terminal overseas offers to charge you in your home currency (SGD) rather than the local currency. Always decline and pay in the local currency. DCC rates routinely run 3–7% worse than your card's own conversion rate.

Digital remittance platforms such as Wise (formerly TransferWise) have disrupted the market by passing the mid-market rate directly to consumers and charging a transparent flat fee. For large transfers — such as sending MYR back to Malaysia or moving funds for property investment — Wise and similar platforms typically beat bank rates by 2–4%, which on a SGD 10,000 transfer represents SGD 200–400 in savings.

When to Convert Currency: Timing Tips for Singapore and Malaysia

The forex market operates 24 hours a day from Sunday evening (Sydney open) to Friday evening (New York close), but not all times are equal. The highest liquidity — and therefore the tightest spreads — occurs when the London and New York sessions overlap (roughly 8 PM to midnight Singapore time). During this window, bid-ask spreads on major currency pairs are at their narrowest.

Weekend and public holiday rates are often worse. Banks and money changers widen their spreads when interbank markets are closed, because they bear more risk holding currency positions. If you need to exchange a large amount, Monday through Thursday during Singapore business hours typically yields better rates than Friday afternoon or weekends.

For the SGD/MYR pair specifically, rates tend to move around Malaysian and Singapore public holiday announcements, BNM monetary policy meetings, and MAS semi-annual policy reviews (April and October). Tracking the SGD/MYR rate over months using tools like XE Historical Charts or Google Finance can reveal seasonal patterns — the MYR has historically weakened in the first quarter of the year and strengthened heading into mid-year.

"The SGD has appreciated over 30% against the MYR since 2010 — making Singapore one of Asia's strongest currency stories."

This long-term SGD appreciation reflects Singapore's consistent current account surpluses, strong foreign reserves, and MAS's policy of allowing gradual SGD appreciation to contain imported inflation. For Singaporeans with family or assets in Malaysia, this means their purchasing power in ringgit has grown substantially over the past decade — making cross-border property investment, education, and retirement planning increasingly attractive.

10 Facts About Currencies and Forex

01

The Singapore dollar (SGD) is managed by MAS under a managed float regime, not a free float — it trades within an undisclosed policy band tied to a basket of trading partner currencies.

02

The Malaysian ringgit (MYR) was pegged at 3.80 to the USD from 1998 to 2005 — one of Asia's most famous currency controls, introduced by PM Mahathir during the Asian Financial Crisis.

03

The Indonesian rupiah (IDR) is one of the lowest-valued currency units in the world — 1 SGD buys over 11,000 IDR, so ATMs in Bali regularly dispense stacks of 100,000 IDR notes.

04

The forex market trades over USD 7.5 trillion per day — making it the largest financial market on Earth by volume, dwarfing the global stock market.

05

Singapore is the world's 3rd largest foreign exchange trading centre, behind London and New York, handling over USD 900 billion in daily FX turnover.

06

The Brunei dollar (BND) is pegged 1:1 to the SGD under the Currency Interchangeability Agreement — you can legally use either currency in both Brunei and Singapore.

07

Vietnam's dong (VND) has so many zeros that ATMs in Vietnam dispense notes of 500,000 VND — worth about SGD 28 at current rates.

08

The Thai baht (THB) is one of ASEAN's most stable currencies, partly because Thailand holds foreign exchange reserves equal to over 40% of GDP.

09

Currency exchange apps typically charge 0.3–1.5% fee, while banks often charge 2–5% on top of the mid-market rate — a difference of thousands of dollars on large transfers.

10

The mid-market rate (also called the interbank rate) is the true exchange rate — the average of buy and sell prices. Consumers rarely get this rate; always ask for the all-in rate before exchanging.

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 adds a spread (typically 2–5%) on top of this rate to generate profit. 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.app 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.
  • In most cases, SGD is the best currency to bring. Malaysian money changers — especially those in Johor Bahru, KL, and Penang — actively compete for SGD business and offer tight spreads. Changing at a licensed money changer on the Malaysian side of the Causeway often yields better rates than changing in Singapore. Avoid changing money at Woodlands Checkpoint or Changi Airport. Withdrawing MYR at a Malaysian ATM using a Wise card or a multi-currency card (like Revolut) is another excellent option that gives rates close to the mid-market.
  • 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.
  • SGD/MYR has broadly trended upward since the early 2000s. In 2010, 1 SGD bought approximately 2.38 MYR. By 2026, that same 1 SGD buys around 3.48 MYR — an appreciation of over 46% in 16 years. This reflects Singapore's stronger productivity growth, larger foreign reserves, and MAS's managed appreciation policy versus Malaysia's more volatile ringgit. During the 2015 commodity crash, MYR fell sharply as Malaysia's oil-linked economy came under pressure, briefly pushing SGD/MYR above 3.10. For detailed historical data, XE.com and the MAS website both publish multi-year rate histories.
  • Airport money changers operate in a captive market — you have limited alternatives and often limited time. They pay high rents to airport operators (Changi Airport Group charges premium retail rates), face lower competition than city-centre operators, and cater to travellers who have not pre-planned their currency exchange. All these factors allow them to charge wider spreads — typically 3–7% above mid-market — compared to 0.3–1% at competitive city money changers. 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 reviews this policy twice a year (April and October) and announces changes in vague terms (e.g., "modest and gradual appreciation"). This policy has made the SGD one of Asia's most stable and predictable currencies.
  • Singapore's most actively traded currency pairs at retail money changers are SGD/MYR (by far the highest volume, driven by JB crossers), SGD/USD, SGD/EUR, SGD/JPY, SGD/IDR, and SGD/AUD. In the wholesale forex market, SGD is most frequently traded against USD, EUR, JPY, and GBP. With Singapore's large South Asian and Filipino expat communities, SGD/INR and SGD/PHP remittance flows are also substantial. SGD/CNY has grown significantly as China-Singapore trade and investment has expanded.
  • 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

How it computes

Conversion is a single multiplication against a published reference rate; the work is entirely in where the rate comes from. Rates are fetched from a RECATOOLS server-side proxy which asks Frankfurter first — European Central Bank daily reference rates — and falls back to open.er-api.com, then to the last good response it cached. There is NO rate table bundled in the page: if every source is unreachable the tool reports that it has no rate rather than converting.

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 — the same rule the site applies to fonts and scripts.
  • 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.
  • Verified live on 2026-09-01: the production endpoint returned HTTP 200, source `frankfurter`, base SGD, 29 currencies, dated 2026-08-31.
  • ⚠️ A rate dated YESTERDAY is normal, not stale. The ECB publishes once per working day at about 16:00 CET, so before that hour — and all weekend — the newest reference rate available anywhere is the previous session's.
  • ⚠️ These are REFERENCE rates, not dealing rates. Nobody transacts at them. A bank or card network adds a spread, and the rate you are actually offered will be worse, sometimes by several percent.

Sources

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. A currency outside it has no quote here at all, which is a deliberate absence rather than a gap to be filled from a less careful source.
  • ECB does not publish on weekends or on TARGET holidays. Friday's rate is served through the weekend, correctly labelled with its own date.
