KEPSS is Kenya’s Real-Time Gross Settlement system, and its migration to the ISO 20022 global messaging standard is one of the most significant payment upgrades in East Africa. Completed on 14 October 2024 by the Central Bank of Kenya, the shift changes how large-value transactions move through the country’s financial system.
It also reflects broader digital transformation across Kenyan banking, as institutions adopt richer, standardised data formats. This positions Kenya as a reference point for African nations still evaluating similar upgrades to their own payment rails and settlement infrastructure.
Understanding KEPSS: The Backbone of Kenya’s Payment Infrastructure
KEPSS is Kenya’s Real-Time Gross Settlement system, run by the Central Bank of Kenya since 2005. It processes large-value and time-critical payments between commercial banks, government agencies, and financial institutions, settling each transaction individually rather than in batches. Between August 2023 and August 2024, KEPSS processed over 5.3 million transactions worth more than Ksh 45 trillion.
Its role extends into domestic and regional large-value transfers, supporting interbank lending, treasury operations, corporate settlements, and cross-border flows with neighbouring countries. This makes KEPSS a foundational piece of Kenya’s banking technology infrastructure and a core part of regional financial connectivity.
The ISO 20022 Migration: What Changed and Why It Matters
The Central Bank of Kenya completed the KEPSS migration to ISO 20022 on 14 October 2024, following a pilot phase and dress rehearsal. ISO 20022 replaces older, narrower messaging formats with a richer data structure that carries more context per transaction, including detailed remittance information and clearer identification of the parties involved.
Such data improves fraud monitoring, strengthens compliance screening, and allows banks to reconcile payments automatically rather than manually. The migration also aligns Kenya with infrastructure many global institutions are adopting, including cloud banking platforms designed for standardised messaging. It positions KEPSS to interoperate smoothly with international systems ahead of SWIFT’s global CBPR+ deadline.
Measurable Gains in Speed, Security, and Efficiency
The Central Bank of Kenya has confirmed faster settlement times, streamlined processing, and improved liquidity management for banks since the migration.
Key gains include:
- Faster settlement of large-value payments between institutions
- Stronger fraud detection through richer transaction data
- Less manual reconciliation work for banks and operators
- Better liquidity visibility across the interbank market
- Smoother cross-border processing with correspondent banks abroad
These gains reduce operational friction and increase confidence in every transaction processed through the system, giving treasury teams a clearer, more predictable settlement cycle to plan around each business day.
Extended Hours and the East African Community’s Cross-Border Vision
The Central Bank of Kenya extended KEPSS operating hours to a revised 7:00 a.m. – 7:00 p.m. slot, which was made effective from 1 July 2025. This supports Kenya’s transition towards a 24/7 digital economy and gives banks a wider window to initiate and complete large-value payments.
The extended hours improve overlap with Real Time Gross Settlement (RTGS) systems in Tanzania, Uganda, and Rwanda, making same-day cross-border settlement within the East African Community more achievable. This supports the region’s interoperability goals and reinforces the role of mobile banking channels that feed transactions into these settlement rails throughout the day, particularly for businesses managing time-sensitive supplier and payroll payments.
What This Means for Financial Institutions and Fintech Players
Banks and fintechs now need systems that can generate and read ISO 20022 messages, raising the bar for internal banking technology and vendor selection. Providers building mobile banking apps must ensure backend integrations handle richer data fields without errors. Institutions that adapt early gain smoother compliance and stronger positioning for regional expansion, while those that delay risk falling behind on messaging compatibility with correspondent banks abroad and slower onboarding into future regional payment schemes.
