Tanzania’s biggest bank overhauls core banking system to chase regional growth

Summary

CRDB Bank, Tanzania’s largest bank by assets, has completed a weekend migration from Fusion Banking Essence (FBE) to Temenos T24. The move is aimed at supporting multi-country operations, improving transaction efficiency, safeguarding customer data and enabling faster product rollouts as CRDB pursues expansion across the region and into Dubai.

Content summary

The bank’s CEO, Abdulmajid Nsekela, said the migration (completed in early September) was essential for regional competitiveness. CRDB already operates in Burundi and the DRC and plans to launch services in Dubai targeting diaspora remittances and trade finance. The new platform supports multiple languages and currencies (Swahili, English, French, Kirundi, Arabic). CRDB experienced some post-migration glitches—customers reported balance discrepancies attributed to large data transfers during the 72-hour migration window. The change aligns CRDB with other East African groups using Temenos T24 to run multi-jurisdiction operations and follows regulatory encouragement from the Bank of Tanzania for system upgrades.

Key Points

CRDB migrated its core banking system from Finastra’s Fusion Banking Essence to Temenos T24 during a 72-hour exercise in early September.
The upgrade aims to support CRDB’s regional expansion—existing operations in Burundi and DRC and planned entry into Dubai for diaspora and cross-border clients.
Temenos T24 offers front-to-back capabilities across multiple currencies and languages, aiding multi-jurisdiction product rollouts.
The migration saw some data-transfer glitches with customer balance discrepancies reported; such core migrations are complex and reputation-sensitive.
The move places CRDB alongside other East African banks (KCB, Stanbic, Equity, DTB, NCBA) that run multi-market core platforms to compete for corporate and cross-border business.
The Bank of Tanzania has been encouraging local banks to modernise systems as part of wider financial-sector reforms.

Context and relevance

Upgrading core banking is a strategic step for banks that want to scale regionally: it reduces integration friction, speeds product launches and improves compliance and data protection across borders. For fintech watchers, payments teams and corporate clients in East Africa and the Gulf, CRDB’s move signals stronger competition for cross-border remittances, trade finance and corporate banking services coming out of Tanzania.
