Root Cause

FAST and PayNow are domestic Singapore payment systems that only support SGD transactions to local bank accounts; transfers to EU accounts require SWIFT/IBAN routing, and omitting the IBAN causes the payment to be rejected or misrouted.

中文

Dead Ends

Common approaches that don't work:

  1. 90% fail

    EU banks require IBAN for SEPA and SWIFT transfers; a local account number without the country code and check digits is not recognized.

  2. 80% fail

    FAST does not support cross-border routing; the intermediary bank would need a SWIFT MT103, which requires IBAN.

  3. 95% fail

    PayNow proxies are only registered with Singapore banks; EU recipients cannot have a PayNow proxy.
