Overview

Note on classification. FAST is not a QR or barcode symbology. It is the interbank rail underneath PayNow QR and SGQR, so the wiki shows no playground for this page. Not to be confused with Türkiye's FAST (Fonların Anlık ve Sürekli Transferi), a separate system.

FAST (Fast And Secure Transfers) is Singapore's electronic funds transfer service for moving Singapore dollars between accounts at participating banks and non-bank financial institutions (NFIs) "almost instantly", 24×7, 365 days a year 2, 3. It was launched on 17 March 2014 1, 8. FAST is owned by the Singapore Clearing House Association (SCHA), operated by Banking Computer Services Pte Ltd (BCS), and settles between participants on MEPS+, the Monetary Authority of Singapore's RTGS system 10. MAS designates it a system-wide important payment system (SWIPS) 8. In 2025 FAST carried 642 million transactions worth S$797.7 billion 11.

History

  • Before FAST. Instant transfers were available only between accounts at the same bank; an interbank transfer could take up to three working days 3, 10. The World Bank calls FAST's introduction "largely market driven" 10.
  • 10 March 2014. The Association of Banks in Singapore (ABS) announced that FAST would go live at 8.00 am on 17 March 2014 with 14 participating banks: ANZ, CIMB, Citibank, DBS/POSB, Deutsche Bank, Far Eastern Bank, HSBC, Maybank, OCBC, RHB, The Royal Bank of Scotland, Standard Chartered, SMBC and UOB 4.
  • 17 March 2014: launch. More than 33,000 transactions worth S$64 million went through in the first two days 5.
  • 8 May 2015. The per-transaction limit rose from S$10,000 to S$50,000 at corporate users' request; FAST was then carrying over 1 million transactions a month 6.
  • 18 September 2015. Bank of China, BNP Paribas, The Bank of Tokyo-Mitsubishi UFJ, Hong Leong Bank and Mizuho joined, taking FAST to 19 banks; 18 million transactions had been made since launch 7.
  • 10 July 2017. ABS launched PayNow QR (PayNow), a proxy-addressing service that runs on FAST 13. The World Bank reports that corporate uptake of FAST was limited until 2016–17 and that PayNow boosted adoption 10. The limit was later raised to S$200,000 per transaction 10.
  • September 2018. MAS took the policy decision to give NFIs such as major e-wallet providers direct access to FAST and PayNow 9.
  • 30 November 2020. MAS announced that NFIs licensed as major payment institutions could connect directly from February 2021, through a new API payment gateway built by the Direct FAST Working Group (BCS, ABS, eight banks and six NFIs) 9.
  • 8 February 2021. The first NFIs went live on FAST 2, 3.
  • 29 April 2021 onward. PayNow, and so FAST underneath it, was linked to Thailand's PromptPay (29 April 2021), India's UPI (February 2023) and Malaysia's DuitNow (November 2023) 14, 15, 16.

Technical specification

FAST defines no symbol and no consumer payload. What the sources describe is a clearing and settlement arrangement:

Layer What the sources show
Owner / governance Singapore Clearing House Association (SCHA) 9, 10
Operator Banking Computer Services Pte Ltd (BCS), set up in 1976 and owned by NETS according to the World Bank 10. BCS's chairman called it "the operator of FAST and PayNow" 9, 14
Overseer MAS, which designates FAST a SWIPS under the Payment Services Act 8
Messaging ISO 20022 between participants and the automated clearing house (ACH), from launch 8, 10
Clearing Instant, by the Singapore Automated Clearing House (SACH) 10
Settlement Deferred net settlement in two cycles per business day on MEPS+; participating banks post collateral with MAS to cover their net outflow position and that of NFIs they settle for, or they are cut off 10
Speed "Almost immediate", 24×7 2; the World Bank gives under 15 seconds 10
Currency SGD only; no transfers to overseas accounts 3
Limit Up to S$200,000 per transaction, subject to each institution's own limits 3
Instruments Credit transfers and direct debits 10; some banks offer collection of payment via FAST 8
Addressing The recipient's account number; the name is "for reference purposes only" 3. Proxies (mobile, NRIC/FIN, UEN, VPA) belong to the PayNow overlay 13
NFI access API payment gateway launched in November 2020 9, 10

Account numbers. The ABS fact sheet is the closest thing to a public interface document. It lists, per participant, the accepted account types and digit lengths, entered as numbers only with no dash or space: for example DBS 10 digits and POSB 9, OCBC 10 digits (savings) or 12 (current), and 10 to 19 for its Virtual Account Service, and GPay Network wallet numbers of 5 to 15 digits 2.

Spec availability. No public FAST message specification (ISO 20022 message set, usage guidelines) was found. MAS and the World Bank say only that ISO 20022 is used 8, 10.

Use cases

  • Person-to-person and account-to-account transfers. ABS presented FAST as a replacement for cash and cheques between people 7.
  • Business payments. The 2015 limit increase was made for corporate users 6. UOB offers FAST to businesses through its Infinity platform, file transfer and APIs 19. The World Bank lists merchant (P2B and B2B) and bill payments 10.
  • Mobile, QR and proxy payments via PayNow. PayNow sends funds "through FAST" using a mobile number, NRIC/FIN or VPA, and PayNow QR is integrated with SGQR 13. By November 2020 PayNow made up almost half of FAST's monthly volume 9.
  • Government disbursements. The World Bank credits PayNow-based government payouts with boosting uptake 10.
  • E-wallet interoperability. Direct NFI access lets e-wallet users move money between bank accounts and e-wallets and across e-wallets, which most e-wallets could not do before 9.
  • Cross-border remittances. The PayNow links to Thailand, India and Malaysia run over gateways built by BCS and the partner operator 14, 15, 16.

Implementations

There is no open-source encoder or decoder, since there is nothing to encode. FAST is implemented by its participants. The ABS fact sheet of 7 July 2026 lists 32 participating bank entities (from Anext Bank to United Overseas Bank, with Hong Leong Finance effective 27 August 2026) and 7 NFIs: GPay Network, Liquid Group, MatchMove Pay, NIUM, SingCash, Wise Asia-Pacific and Xfers 2. The World Bank's 2021 count was 28 (23 banks, 5 NFIs), with no indirect participants 10. Mastercard's Vocalink helped implement FAST's immediate transfers and debit requests 10. Helpdesk enquiries go to BCS (FAST@bcs.sg) 2.

When to choose which. FAST suits a transfer that must arrive at once to a known account number, up to S$200,000 3. If you only have the payee's phone number, UEN or a QR code, you use PayNow, which still settles over FAST 13. GIRO remains for transfers to non-participating banks 3 and, as of 2026, for larger payments to government agencies 17.

Fun facts

  • A shifting count. ABS's FAQ of 5 February 2021 named 21 institutions in one answer and then spoke of "24 participating banks", "20 participating banks", "5 NFIs" and a list of six NFIs within the same document 20. The current FAQ simply refers readers to the fact sheet 3.
  • From launch volumes to today. The first two days carried 33,000 transactions 5; in H2 2025 alone FAST carried 344 million 11.

Status

Active and growing. Annual FAST volume rose from 380 million transactions in 2023 12 to 500 million (S$661.7 billion) in 2024 and 642 million (S$797.7 billion) in 2025. Average size fell from S$1,323 to S$1,242 11. ABS updated the fact sheet on 7 July 2026 and the FAQ on 23 July 2026 1. On 25 June 2026 MAS and ABS announced a PayNow Generation 2 study of the national instant-payments infrastructure. Its priorities are PayNow–NETS QR interoperability (pilot by end-2026), deep links in PayNow QR codes, larger-value payments to government agencies, and longer-term capabilities such as request-to-pay, structured reconciliation data and a micro-payments rail. An implementation roadmap is due by end-2026 17. No successor to FAST has been announced. Country context: Singapore report.
