Quick answer. Changi has DBS, OCBC, and HSBC ATMs across the arrival halls of all four terminals, dispensing Singapore dollars at the real interbank rate, and Singapore banks add no operator surcharge on foreign cards, so a bank ATM here is genuinely cheap (you pay only your home-bank fees). Changi's Travelex and UOB money changers are competitive for an airport, fine for a small starter float, but the downtown changers at The Arcade (Raffles Place) and the 24-hour Mustafa Centre beat them for any larger exchange. Singapore has no Bank of America Global ATM Alliance partner, but it hardly matters given the no-surcharge banks. Always decline DCC and choose SGD. To the city: tap any contactless bank card straight onto the MRT (East-West line, ~30-40 min, ~S$2 plus a ~S$0.60/day SimplyGo fee), or take a taxi (~S$25-45) or Grab.
Where to get Singapore Dollar at SIN
Changi's arrivals money setup is unusually good: DBS, OCBC, and HSBC bank ATMs that add no operator surcharge, plus competitive licensed money changers (Travelex, UOB, ChangiFX). The one thing to know is that the downtown changers (The Arcade, Mustafa) still beat the airport for larger exchanges. The cost math below assumes you withdraw or exchange the equivalent of $100.
| Option | Where | Markup | Total Cost |
|---|---|---|---|
| DBS / OCBC / HSBC ATM (Changi arrivals, no surcharge) | Changi T1-T4 arrival halls | Interbank rate, no bank operator fee | ~$100 + home-bank fee only |
| The Arcade / Mustafa downtown changer (NOT at airport) | Raffles Place / Little India | Best rates in the city (beats banks and airport) | ~$100-101 |
| Travelex / UOB / ChangiFX changer (Changi arrivals) | Changi arrival and departure halls | Competitive for an airport, slightly behind downtown | ~$97-99 |
| Standalone independent ATM (Clarke Quay nightlife, NOT a bank) | Nightlife venues, some hotel lobbies | S$3-8 fee + DCC | ~$90-95 |
| Hotel concierge / Marina Bay strip exchange | Hotel desks, MBS strip | 'no commission' framing, 5-10% in the rate | ~$90-95 |
Where to find the DBS, OCBC, and HSBC ATMs at Changi (SIN)
Singapore Changi Airport (SIN) is the country's only major airport and one of the world's best, with four terminals plus the Jewel retail-and-nature complex attached to Terminal 1. The money setup in arrivals is unusually traveler-friendly. Bank-branded DBS, OCBC, and HSBC ATMs are distributed across the arrival halls and basements of all four terminals, and the crucial Singapore fact is that the local banks do not add their own operator surcharge on foreign-card withdrawals, so a Changi bank ATM gives you SGD at the interbank rate for only whatever your home bank charges. Changi also has licensed money changers (Travelex, UOB, ChangiFX, Prosegur) in both arrival and departure halls, and unlike almost every other airport in the world Changi's changer rates are competitive, fine for a small arrival float. That said, the genuinely best rates in Singapore are at the downtown licensed changers, The Arcade at Raffles Place and the 24-hour Mustafa Centre in Little India, which beat Changi by roughly half a percent to one percent, so change only a starter amount here and the rest in town if you need a lot of cash. Singapore has no Bank of America Global ATM Alliance partner, but because the banks add no surcharge it makes little practical difference. Decline DCC and choose SGD.
Terminals 1, 2, 3, and 4 (plus Jewel at T1)
Singapore Airlines and Scoot (the home carriers, mainly T1/T2/T3), plus most major international carriers across the four terminals: United, Qantas, Emirates, Qatar, Cathay Pacific, ANA, JAL, British Airways, Lufthansa, Air France, and the regional Southeast Asian airlines. Changi is a major Asia-Pacific hub and consistently rated among the world's best airports; Jewel (attached to T1) is the famous retail-and-nature complex with the Rain Vortex
DBS, OCBC, and HSBC ATMs are distributed across the arrival halls and basements of all four terminals (for example the T2 and T3 arrival halls and basements), all free of operator surcharge on foreign cards. The Travelex, UOB, and ChangiFX money changers are in both arrival and departure halls; they are competitive for an airport but the downtown changers beat them. Use a bank ATM or change a small float, decline DCC, choose SGD, then tap your contactless card onto the MRT.
Do you actually need cash at Singapore Changi (SIN)?
No, for almost everyone. The MRT takes a contactless card tap, taxis and Grab take cards, and Singapore is intensely cashless with no tipping. Here is what works on a card on the way into the city, and the narrow cases where you will still want a little cash:
MRT via SimplyGo (East-West green line) (~S$2 + ~S$0.60/day SimplyGo fee): Tap any contactless Visa/Mastercard/Amex directly at the gate, no ticket needed. ~30-40 min to the city, changing at Tanah Merah. The cheapest and usually fastest option with manageable luggage.
Metered taxi (arrivals rank) (~S$25-45 to downtown): From the official rank; meter plus a Changi airport surcharge (higher late night and weekend afternoons). Cards accepted. ~20-30 min by road.
Grab (rideshare app) (~S$20-40 to downtown): Book in-app from the arrivals pickup point, pay by card in-app. Similar to a taxi, often slightly cheaper off-peak.
Airport shuttle / hotel transfer (~S$10 shared shuttle per person): The shared airport shuttle drops at most city hotels; book at the arrivals counter or online. Useful with heavy luggage or for a group.
⚠ DCC trap. When the ATM or terminal asks if you want to be charged in your home currency instead of the local currency, always decline and choose the local currency. Accepting locks in a 3-13 percent markup that your no-FX-fee card cannot undo. Full DCC explainer →
Frequently Asked Questions
Do I need cash to get from Singapore Changi (SIN) to Singapore?
No. MRT via SimplyGo (East-West green line) accepts contactless. Most taxis accept cards. Uber and other apps are card-only.
Can I order Singapore Dollar before flying?
Yes. CEI Currency Exchange ships physical Singapore Dollar to your US address in 2-5 days at rates well below airport counters. Order 50-100 Singapore Dollar for taxis and tips on day one.
Which ATM at Changi is best for foreign cards?
Any of the bank ATMs, because Singapore banks do not add an operator surcharge on foreign cards. DBS (the largest network), OCBC, and HSBC all have machines across the Changi arrival halls and dispense Singapore dollars at the real Visa or Mastercard interbank rate, so you pay only your home bank's fees. Ignore the widely-quoted S$5-7 'DBS fee', that is what DBS charges its own customers to withdraw abroad, not what a foreign card pays in Singapore. Just decline DCC (the 'charge in your home currency' prompt) and choose SGD. The only machines to avoid are the rare standalone independent units; the bank ATMs in the terminals are all fine and free of operator surcharge.
Is there a Bank of America Global ATM Alliance partner at Changi or in Singapore?
No, Singapore has no Bank of America Global ATM Alliance partner (in Asia-Pacific the Alliance is covered only by Westpac in Australia and New Zealand and Deutsche Bank in India). But it barely matters here, because Singapore banks (DBS, POSB, OCBC, UOB) do not add their own ATM operator surcharge on foreign cards. So a BoA debit card at a Changi bank ATM only pays BoA's own 3 percent non-network fee, with nothing added on the Singapore side. Even so, a no-FX-fee card is better: a Wise or Charles Schwab card gives zero foreign-transaction fee and the real interbank rate, and it taps straight onto the MRT, which is the cleanest way to handle a Singapore trip.
Should I change money at Changi airport or wait until the city?
Changi is the rare airport where changing a small amount is fine, but the city is still better for larger sums. Changi's licensed money changers (Travelex, UOB, ChangiFX) are competitive by airport standards, unlike the rip-off counters at most airports, so changing S$50-100 to get going is reasonable. For any larger exchange, the downtown licensed changers at The Arcade (11 Collyer Quay, Raffles Place) and the 24-hour Mustafa Centre in Little India beat Changi by roughly half a percent to one percent on US dollars and major Asian currencies. And because the bank ATMs at Changi add no surcharge, simply withdrawing SGD from a DBS or OCBC machine is often the simplest cheap option of all.
How do I get from Changi to the city?
The MRT is the standout option. Tap any contactless Visa or Mastercard directly at the Changi MRT gate via the SimplyGo system (no ticket needed), ride the East-West (green) line, change at Tanah Merah onto the main line, and reach City Hall or the Marina Bay area in about 30-40 minutes for roughly S$2 plus a small ~S$0.60/day SimplyGo admin fee on foreign cards. A metered taxi from the arrivals rank runs about S$25-45 to downtown (an airport surcharge applies, higher late at night and on weekend afternoons), and Grab is similar, charged in-app. For most travelers with manageable luggage, the MRT tapped with a contactless card is the cheapest and fastest way into Singapore.
Do I need cash to leave Changi?
No. The MRT takes a contactless card tap, taxis and Grab take cards, and Singapore is so cashless you can go your whole trip spending almost nothing in physical cash. You only need a little cash for the share of hawker stalls and wet markets that are cash-first, and there is no tipping, so no gratuity cash either. If you want a small SGD float on arrival, withdraw it from a no-surcharge DBS or OCBC ATM in the terminal, or change a little at the Changi money changer; otherwise just tap your card onto the MRT and go.
Can I order Singapore dollars before flying?
Yes, though you need very little. CEI Currency Exchange ships physical Singapore dollars to your US address in 2-5 days at a rate below the airport counters, useful for a short stopover or if you simply like having a starter float in hand. But Singapore is so card-and-contactless-driven that most travelers barely touch cash, so a small amount goes a long way. The cleanest setup is a no-FX-fee contactless card (Wise or Schwab) that taps the MRT and pays nearly everywhere, plus a little SGD for hawker stalls, topped up at a no-surcharge bank ATM or a downtown money changer if needed.
Can I claim the GST refund at Changi?
Yes. Tourists can reclaim Singapore's 9 percent GST on goods (not services or hotels) over S$100 via the eTRS scheme. Show your passport at participating retailers when you buy, then process the refund at the eTRS self-help kiosks at Changi departures before check-in or immigration, with the refund paid to your card, in cash, or to an e-wallet. Keep your receipts and allow extra time at the airport. This is separate from the currency questions, but it is worth a meaningful amount on big Orchard Road shopping and is one more reason a Singapore trip leans on cards (the refund tracks the card you paid with).
