Kuwait's payment infrastructure has undergone a transformation since 2021 that is easy to miss from outside the Gulf. The Central Bank of Kuwait (CBK) has systematically rebuilt its national payment systems - upgrading the RTGS to ISO 20022, launching instant payments through WAMD, extending operating hours six times in under two years, and opening a new automated clearing house in January 2026. This guide covers the full stack.

KASSIP - Real-Time Gross Settlement

The Kuwait Automated Settlement System for Inter-Participant Payments (KASSIP) is Kuwait's RTGS, operated by the CBK.

Current generation: The CBK launched the upgraded "new generation" KASSIP on 30 August 2021 as part of the Kuwait National Payments System Project. The upgrade replaced SWIFT connectivity with CBK-Net (a private encrypted VPN), adopted ISO 20022 messaging, and doubled transaction processing capacity and speed compared to the original 2004 system.

Operating hours: 07:00 to 23:15 local time on business days, weekends, and official holidays. Customer-facing interbank transfers are available until 23:00. This near-18-hour window is the result of six progressive extensions since May 2023, when hours were first expanded beyond the original 07:00-14:15 business-day-only window. The latest extension, effective April 2025, added weekend and holiday availability.

Settlement model: Pure gross settlement - each payment is processed individually and irrevocably in central bank money. No minimum payment limit applies. KASSIP also settles the net positions produced by ancillary systems, including the KECCS cheque clearing system and the new KACH automated clearing house.

Network: CBK-Net, a closed private network using encrypted VPN tunnels. This replaced SWIFT connectivity in the 2021 upgrade, giving the CBK full control over the network infrastructure.

Participants: All local Kuwaiti banks, branches of foreign banks operating in Kuwait, and the CBK itself. In December 2023, Kuwait Clearing Company (Maqasa) also joined KASSIP as a participant.

Standards: ISO 20022 messaging. PFMI-compliant. Purpose of payment codes became mandatory across all national payment systems from 10 April 2025.

WAMD - Instant Payments

WAMD (meaning "lightning flash" in Arabic) is Kuwait's instant payment system, launched in June 2024.

Operator: KNET (the Shared Electronic Banking Services Company) operates WAMD under CBK supervision.

Technology: Built on ACI Worldwide's Digital Central Infrastructure platform. Implementation was completed in under 15 months.

Adoption: WAMD onboarded 30% of Kuwait's banked population within its first three months of operation and surpassed 1 million registered accounts within its first year. All Kuwaiti banks are live on the platform. Real-time transaction volumes increased more than 12 times since launch.

How it works: Account-to-account transfers using a mobile phone number as a proxy identifier. Available 24/7 via mobile banking apps and internet banking.

Confirmed live banks: National Bank of Kuwait (first to go live, 30 June 2024), Kuwait Finance House, Gulf Bank, Warba Bank, Burgan Bank, Kuwait International Bank, Weyay Bank, and others - 100% of local banks are onboarded.

Upcoming features: KNET has announced plans for fintech integration, dynamic QR code payments at point-of-sale terminals, and a Request to Pay service for e-commerce.

KNET - The National Financial Switch

KNET (the Shared Electronic Banking Services Company) is Kuwait's domestic card switch and central payment infrastructure provider, established in 1992 with electronic services launching in 1994.

Role: KNET connects all local banks through the Financial Switch of Kuwait and serves as: Domestic debit card switch - processing all debit card transactions across ATMs, POS, and e-commerce Payment gateway operator - the KNET Payment Gateway (launched 2004) accepts all local debit cards from 11 member banks WAMD instant payment scheme operator ATM network operator (1,200+ terminals) POS network operator (25,000+ terminals) Government payment services gateway

Regulatory status: KNET is classified as an Electronic Payment Infrastructure Provider (EPIP) under CBK's regulatory framework, operating under direct CBK supervision.

GCC connectivity: KNET extends services across the Gulf through the GCC-Net interconnection - launched in 1997 for ATMs and extended to POS terminals in 2014 via Gulf POS.

KACH - Kuwait Automated Clearing House

The newest component of Kuwait's payment stack, KACH launched on 5 January 2026.

Purpose: Unified platform for low-value, repetitive financial transactions among participating banks. CBK describes it as the "2nd version of the Kuwait National Payments System."

Settlement model: Deferred net settlement - KACH produces net positions after clearing sessions and settles them automatically through KASSIP.

Technical specifications: ISO 20022 compliant, runs on CBK-Net, supports Straight Through Processing (STP). Operates continuously including public holidays.

Significance: Before KACH, Kuwait lacked a dedicated automated clearing house for batch processing. Payroll, utility bills, and recurring payments were processed through less standardised channels. KACH brings Kuwait in line with the batch clearing infrastructure that most Gulf states already operate.

Cross-Border: AFAQ Connection

Kuwait joined the GCC's AFAQ cross-border RTGS in March 2022, with the CBK and Boubyan Bank completing the first phase. A second phase in January 2023 added six additional banks: National Bank of Kuwait, Kuwait Finance House, Ahli United Bank, Commercial Bank of Kuwait, Burgan Bank, and Kuwait Industrial Bank. KFH now offers AFAQ transfers directly through its consumer banking app.

In total, 8 Kuwaiti entities (7 banks plus CBK) are connected to the pan-GCC system, enabling cross-border real-time settlement in local GCC currencies plus USD and EUR.

Regulatory Developments

Open banking: CBK issued a draft Open Banking Regulatory Framework in June 2025, built around four principles - utility, transparency, security, and adoption. The framework would enable banks and licensed fintechs to share customer data with consent for account aggregation, spending insights, and direct payment initiation. A phased rollout is planned following the public consultation.

Fraud prevention: CBK launched the Fraud Shield Initiative, a strategic programme for electronic financial fraud detection and prevention, alongside an innovation hub called Wolooj covering fintech, regtech, and cybersecurity.

Cyber resilience: A dedicated Cyber and Operational Resilience Framework (CORF) was introduced for all local banks and financial institutions.

What Practitioners Should Know

Kuwait's payment infrastructure is now among the most complete in the GCC. The sequence of launches - KASSIP upgrade (2021), WAMD instant payments (2024), KACH clearing house (2026) - means the country now has all three standard payment rails operating on ISO 20022 with modern infrastructure.

The near-18-hour KASSIP operating window, including weekends and holidays, addresses a practical challenge in Gulf markets where the working week runs Sunday to Thursday and religious holidays can span multiple consecutive days.

For institutions routing payments to Kuwait, WAMD handles real-time retail transfers 24/7 using mobile proxy IDs. KACH processes batch payments with deferred net settlement through KASSIP. KASSIP itself handles high-value interbank transfers with no minimum or maximum limits. Cross-border GCC transfers route through AFAQ.

The main gap is that Kuwait is not a BIS CPMI member, so it does not appear in Red Book statistics. The CBK publishes limited aggregate data, making independent volume verification difficult.
