## Overview

> **Note on classification.** This entry was originally bucketed as a QR standard, but fast is **not a QR-symbol standard** — it is an instant-payment rail (see sgqr / paynow for the QR layer). Reclassified as `Instant payment`. The wiki shows no playground because there is no QR payload to encode; the slug is retained to avoid breaking incoming links.

**FAST (Fast And Secure Transfers)** is **Singapore's national instant-payment rail**, launched **17 March 2014** and operated by the **Singapore Clearing House Association (SCHA)** via **Banking Computer Services Pte Ltd (BCS)** <sup>[1][1], [2][2], [3][3], [Singapore report](https://docs.barcoder.ai/docs/payments/SG)</sup>. FAST is the **underlying instant-payment infrastructure** that [PayNow QR](https://docs.barcoder.ai/docs/standards/paynow-qr) (2017) and [SGQR](https://docs.barcoder.ai/docs/standards/sgqr) (2018) ride on top of — making it the foundational rail beneath Singapore's entire mobile-payment + QR-payment ecosystem.

FAST enables customers of **19 participating banks** to transfer SGD funds between banks **almost instantly**, 24/7/365. Inter-participant settlement occurs on **MEPS+** (Singapore's RTGS). FAST adopted **ISO 20022 messaging** from the outset — making it one of the earliest ISO-20022-native national instant-payment rails globally. **August 2020** marked a structural inflection: **MAS opened FAST and PayNow access to non-bank financial institutions (NBFIs)** <sup>[5][5]</sup> — allowing e-wallets like GrabPay, Liquid Pay, and Singtel Dash to participate as direct rail-access entities. This NBFI-access expansion has been widely cited as a global best-practice for instant-payment-rail openness.

## History

**Background — Singapore's pre-FAST payment infrastructure** <sup>[3][3], [Singapore report](https://docs.barcoder.ai/docs/payments/SG)</sup>:
- **GIRO** (since 1980s) — batch-clearing system; T+1 settlement.
- **MEPS+** — Singapore's RTGS for large-value settlement.
- **Cheques** — declining but still used.
- **Card networks** (Visa, Mastercard, NETS) — for retail.
- Pre-FAST: cross-bank transfers took 1-2 business days via GIRO.

**Late-2000s / early-2010s — FAST design** <sup>[3][3]</sup>:
- Singapore's ABS (Association of Banks in Singapore) coordinates design of a national instant-payment rail.
- **MEPS+ underlying RTGS** as settlement layer.
- **ISO 20022 messaging** chosen from design phase — ahead of most peer countries.

**17 March 2014 — FAST launches** <sup>[1][1], [3][3]</sup>:
- Launched with banks as initial participating members.
- 19 participating banks at launch — comprehensive coverage of Singapore's retail banking.
- 24/7/365 instant SGD transfers.

**10 July 2017 — PayNow launches atop FAST** <sup>[5][5], [Singapore report](https://docs.barcoder.ai/docs/payments/SG)</sup>:
- ABS announces [PayNow QR](https://docs.barcoder.ai/docs/standards/paynow-qr) as a P2P overlay service on FAST.
- Phone-number/NRIC-as-proxy addressing.
- 7 banks at PayNow launch.

**September 2018 — [SGQR](https://docs.barcoder.ai/docs/standards/sgqr) launches** <sup>[Singapore report](https://docs.barcoder.ai/docs/payments/SG)</sup>:
- Singapore's unified QR-payment standard — sits atop PayNow + other rails.
- World's first unified national QR standard.

**August 2020 — Non-Bank Financial Institutions get FAST and PayNow access** <sup>[5][5]</sup>:
- **MAS announces NBFIs can directly access FAST and PayNow**.
- Major fintechs (GrabPay, Singtel Dash, Liquid Pay, etc.) join.
- Structurally significant: NBFIs no longer must rely on a bank partner for instant-payment-rail access.

**Cross-border integrations (PayNow-based, via FAST)** <sup>[Singapore report](https://docs.barcoder.ai/docs/payments/SG)</sup>:
- **2021** — PayNow-PromptPay cross-border link with Thailand.
- **2023** — PayNow-UPI cross-border link with India.
- FAST is the underlying Singapore-side rail for these cross-border arrangements.

**2024+ — Maturity** <sup>[Singapore report](https://docs.barcoder.ai/docs/payments/SG)</sup>:
- FAST + PayNow + SGQR ecosystem reaches near-saturation.
- ISO 20022 messaging across the stack.
- Australia, Hong Kong, Thailand, India interoperability paths developed.

## Technical specification

FAST is **Singapore's instant-payment-rail foundation** <sup>[1][1], [2][2], [3][3]</sup>:

| Layer | Description |
|---|---|
| **Owner** | **Singapore Clearing House Association (SCHA)** |
| **Operator** | **Banking Computer Services Pte Ltd (BCS)** |
| **Regulator** | **Monetary Authority of Singapore (MAS)** |
| **Messaging standard** | **ISO 20022** (from launch in 2014) |
| **Inter-participant settlement** | **MEPS+** (Singapore RTGS) |
| **Settlement timing** | Nearly instant; final settlement via MEPS+ |
| **Currency** | SGD |
| **Availability** | 24/7/365 |
| **Participants** | 19 banks at launch; expanded to include NBFIs since Aug 2020 |
| **Overlay services** | [PayNow QR](https://docs.barcoder.ai/docs/standards/paynow-qr) (2017), [SGQR](https://docs.barcoder.ai/docs/standards/sgqr) (2018), [SGQR+](https://docs.barcoder.ai/docs/standards/sgqr-plus) (2022) |

**ISO 20022 from launch (2014)** <sup>[2][2], [3][3]</sup>:
- FAST was an **early adopter of ISO 20022** — long before the SWIFT migration deadline (2025).
- Native ISO 20022 simplified later international integrations (PayNow-PromptPay, PayNow-UPI).

**MEPS+ inter-participant settlement** <sup>[3][3]</sup>:
- FAST is **technically near-real-time messaging + deferred-net-settlement on MEPS+**.
- Customer experience is instant; back-end settlement aggregates across MEPS+ cycles.

**NBFI access (Aug 2020+)** <sup>[5][5]</sup>:
- MAS announcement allowed NBFI participation in FAST + PayNow as direct rail-access entities.
- Major fintechs (GrabPay, Singtel Dash, Liquid Pay, others) joined.
- Made Singapore one of the **first major economies to open instant-payment rails to non-bank fintechs at full direct-access tier**.

## Use cases

**P2P transfers (via PayNow)** <sup>[Singapore report](https://docs.barcoder.ai/docs/payments/SG)</sup>: Most consumer FAST transactions are addressed via PayNow proxies (mobile/NRIC/UEN) rather than raw IBAN.

**Merchant payments (via SGQR + PayNow)** <sup>[Singapore report](https://docs.barcoder.ai/docs/payments/SG)</sup>: Customers scan SGQR; payment routes through PayNow → FAST → settlement.

**E-commerce checkout** <sup>[Singapore report](https://docs.barcoder.ai/docs/payments/SG)</sup>: Online merchants accept FAST-based payments via bank or NBFI integrations.

**Cross-border (PayNow-PromptPay, PayNow-UPI)** <sup>[Singapore report](https://docs.barcoder.ai/docs/payments/SG)</sup>: FAST is the Singapore-side rail for cross-border instant payments to Thailand and India.

**B2B payments** <sup>[1][1]</sup>: 24/7 instant inter-business transfers — replaces GIRO for time-sensitive payments.

**Government disbursements** <sup>[Singapore report](https://docs.barcoder.ai/docs/payments/SG)</sup>: COVID-era SG Bonus and Solidarity Payments were distributed via PayNow/FAST.

## Implementations & ecosystem

**Owner**: **Singapore Clearing House Association (SCHA)**.

**Operator**: **Banking Computer Services Pte Ltd (BCS)**.

**Regulator**: **Monetary Authority of Singapore (MAS)**.

**Bank participants (19+ at launch; near-complete coverage of Singapore banking)** <sup>[1][1]</sup>: All major banks operating in Singapore.

**NBFI participants (post-Aug 2020)**:
- **GrabPay**.
- **Singtel Dash**.
- **Liquid Pay**.
- Other major Singaporean e-wallets.

**Overlay services** <sup>[Singapore report](https://docs.barcoder.ai/docs/payments/SG)</sup>:
- **[PayNow QR](https://docs.barcoder.ai/docs/standards/paynow-qr)** (since 2017).
- **[SGQR](https://docs.barcoder.ai/docs/standards/sgqr)** (since 2018).
- **[SGQR+](https://docs.barcoder.ai/docs/standards/sgqr-plus)** (since 2022).

**Cross-border partners**:
- **NITMX/ITMX (Thailand)** for PayNow-PromptPay (2021).
- **NPCI (India)** for PayNow-UPI (2023).

**No public open-source SDK** — FAST integration via participating bank/NBFI APIs.

## Fun facts

- **ISO 20022 native from 2014**: FAST was one of the earliest ISO-20022-native national instant-payment rails globally — years before the SWIFT migration deadline of 2025 made it a global standard.
- **MEPS+ underneath**: FAST's near-real-time messaging + deferred-net-settlement-on-MEPS+ architecture is structurally clean — and it works at Singapore's scale because of low transaction-count-per-capita-from-Asian-megamarket perspective.
- **NBFI access in 2020 was structurally innovative**: MAS allowing **non-bank fintechs to directly access FAST and PayNow** in 2020 was an industry-leading regulatory move that other countries have since studied. UK Open Banking and various EU NBFI regimes followed similar patterns.
- **3 overlay services on the same rail**: FAST supports PayNow (2017), SGQR (2018), SGQR Plus (2022) — a single underlying rail with multiple stacked overlay services. Compare with Pix Brazil where the QR + alias features are integrated into one product, or UPI India where the multiple overlays sit similarly above NPCI's rail.
- **Cross-border via FAST-rail-bound overlays**: PayNow-PromptPay (2021) and PayNow-UPI (2023) cross-border integrations use FAST as Singapore-side rail. FAST's ISO 20022 + 24/7 availability made cross-border interop technically straightforward.
- **19 banks at launch = essentially full Singapore retail-banking coverage**: FAST's launch with 19 banks day-1 is structurally distinct from peer launches that often start with 2-3 banks and expand. Singapore's small banking landscape allowed comprehensive participation from the outset.
- **BCS as operator**: Banking Computer Services Pte Ltd is a specialised payments-operations subsidiary owned by the major Singapore banks. Similar structurally to Italy's SIA (now Nexi) or Switzerland's SIX.
- **24/7/365 since 2014**: FAST was 24/7 from launch — 4 years before US RTP (Nov 2017) and 9 years before FedNow (Jul 2023). Singapore was an early mover.
- **Foundation for cross-border real-time interop**: The PayNow-PromptPay (2021) link was the **world's first multi-currency cross-border real-time payment** between national instant rails. FAST + ISO 20022 + MAS-coordinated central-bank cooperation made it possible.

## Comparison

| Feature | FAST (SG) | NPP (AU) | RTP (US) | FedNow (US) | TIPS (EU) |
|---|---|---|---|---|---|
| Launch | **17 Mar 2014** | Feb 2018 | Nov 2017 | Jul 2023 | Nov 2018 |
| Owner | SCHA (banks) | NPP Australia (banks) | The Clearing House (banks) | Federal Reserve | Eurosystem |
| Messaging | **ISO 20022 (native)** | ISO 20022 | ISO 20022 | ISO 20022 | ISO 20022 |
| Settlement underlying | MEPS+ (RTGS) | RBA RTGS | Fed | Federal Reserve directly | TARGET2 |
| NBFI access | **Direct (since Aug 2020)** | Limited | Limited (banks-first) | Banks-first; NBFIs via banks | Direct (since 2024+) |
| Cross-border partners | **TH (2021), IN (2023)** | None major | None major | None major | EU-internal SCT Inst |
| Capacity | High | High | High | High | **500 payments/sec, 43M/day** |

**Closest peer**: TIPS (EU) — both are 24/7 ISO-20022 instant-payment rails with NBFI access and cross-border ambition. FAST predates TIPS by ~4 years.

**Structural distinction**: FAST's **2014 launch with NBFI access by 2020 + 2 cross-border integrations by 2023** makes it one of the **most cross-border-integrated mature instant rails globally**.

## Status

**Active, foundational rail of Singapore's payment ecosystem** <sup>[1][1], [Singapore report](https://docs.barcoder.ai/docs/payments/SG)</sup>:
- **17 March 2014 launch**.
- **19 banks + NBFIs** (since Aug 2020).
- **ISO 20022 native** messaging.
- **MEPS+ inter-participant settlement**.
- **24/7/365**.
- **Foundation for** [PayNow QR](https://docs.barcoder.ai/docs/standards/paynow-qr), [SGQR](https://docs.barcoder.ai/docs/standards/sgqr), [SGQR+](https://docs.barcoder.ai/docs/standards/sgqr-plus).
- **Cross-border**: PayNow-PromptPay (TH, 2021), PayNow-UPI (IN, 2023).

**Outlook**: Continued cross-border integration (likely [DuitNow QR](https://docs.barcoder.ai/docs/standards/duitnow-qr) MY, possibly Vietnam, Indonesia), deeper NBFI participation, and possible role in BIS Project Nexus (multi-country instant-payment interconnection initiative).
