What to know
Typical bank debit card, paid in the local currency
Visa or Mastercard converts the JPY to SGD at the tap, at its own rate. The bank holds an SGD amount and adds 3.25% in fees on top.
- Total
- 3.25% of the SGD amount, on top of the scheme's rate, at DBS, OCBC and UOB
- Bank
- 2.25% at DBS and OCBC. UOB states 3.25% without a split
- If the shop converts
- 2.8% at DBS, plus the shop's margin, see flow B
Key facts
- The amount comes straight out of your account in SGD. DBS deducts it directly, and the card must be enabled for overseas use first.
- DBS says the rate comes from wholesale interbank or government-mandated rates. DBS, OCBC and UOB all say a currency other than USD is converted into USD first and then into SGD.
- Visa says its system applies the rate available at authorisation for clearing and settlement, and Mastercard says its rates are specific to the date and time the bank authorises the payment.
- Visa lets an issuer add a percentage to its rate and requires the issuer to disclose it. HSBC shows 1.5% of its own plus up to 1% from Visa.
Not in the public record The gap between the scheme rate and a mid-market rate is not stated. Nor is when UOB converts a foreign-currency hold, or how long a debit hold lasts before the merchant's claim posts.
Notes on the earns and pays rows
The parties and the order of the cuts follow the card payments piece. Industry practice, and no market's split is quoted. The percentages are DBS fees on the SGD amount, from its foreign transaction fee guide, which gives the same split for debit and credit cards. They are fees and not a second conversion. OCBC's debit fee schedule gives the same 1 percent and 2.25 percent split, and UOB's debit agreement states 3.25 percent as one figure. A debit card has no credit line, so the issuer carries no credit losses and earns no card interest.
