Interswitch Enters Banking Tech Race with Temenos Deal

Interswitch is moving beyond payment processing to compete directly for the core infrastructure of African banking. On June 4, 2026, the Nigerian fintech announced a partnership with global software provider Temenos, according to Techpoint. This deal marks a strategic shift from payments-only infrastructure toward full-scale banking technology services.

The partnership allows Interswitch to integrate Temenos’ systems for core banking, digital banking, payments, wealth management, and financial crime into its existing offering. The company is no longer just processing transactions; it is positioning itself to help banks run entire operations on its infrastructure, whether cloud-hosted or on-premise. This moves Interswitch into a new category as a full banking technology provider.

African banks face significant pressure to modernize. Many institutions still rely on outdated systems that are expensive to upgrade and slow to evolve. As demand for digital banking rises in markets such as Nigeria, Kenya, Ghana, and Côte d’Ivoire, Interswitch is using Temenos’ global software and its own local footprint to bridge the gap between legacy systems and digital-first finance.

The trajectory of this move was set years ago. Founded in 2002, Interswitch has transitioned from a transaction-switching company into a major player in payments and digital commerce. The company currently works with over 300 financial institutions across more than 30 countries. Following expansions into broader infrastructure and enterprise services around 2024 and 2025, this partnership represents the next stage of that evolution.

This deal reflects a broader competition across the African fintech ecosystem. The battleground has shifted from simple payment processing to the control of the underlying banking infrastructure. As the banking-as-a-service market in Africa and the Middle East is expected to grow through 2026, Interswitch is signaling that it intends to power the entire banking stack, not just the transactions flowing through it.

The question for the industry is whether Interswitch can successfully manage the complexity of core banking software as effectively as it has managed payment rails.
