Grab announced on May 20 that it will acquire full control of Superbank, Indonesia's digital lender, after Singtel transfers its stake to GXS Bank, lifting Grab's combined holding above 50%. Superbank, which listed on the Indonesia Stock Exchange in December 2025, had a market value of approximately US$1.6 billion as of the announcement date. GXS Bank, the digital banking joint venture between Grab and Singtel, will facilitate the transaction. Superbank's results will be fully consolidated into Grab's financials beginning May 2026, and Grab stated it will provide updated group guidance during its second-quarter earnings call in August. The move marks a strategic expansion of Grab's financial services footprint in Southeast Asia, where digital banking integration with super-app platforms is reshaping the regional fintech landscape.
Consolidation Timeline and Financial Milestones
Superbank posted its first full-year profit in 2025, a significant milestone for the digital lender. As of April 2026, the bank reported more than six million customers and over one million daily transactions across Indonesia. The bank's financial metrics reflect operational strength: by December 2025, its Net Interest Margin (NIM), a measure of lending profitability, reached 10.64%, while its Capital Adequacy Ratio (CAR), which measures capital against risk, stood at 93.24%.
Business Model and Ecosystem Strategy
Superbank's rapid profitability stems from its targeted approach to Indonesia's underserved market, where 77% of adults are unbanked or underbanked. The bank employs an "Ecosystem Clearing House" strategy that leverages shareholder platforms including Grab and OVO, an Indonesian digital payments and services platform, to acquire and retain customers. This approach has proven effective: Superbank launched in June 2024 and achieved profitability within less than a year. Products such as Celengan, a micro-savings offering with a 10% per annum rate, have been instrumental in driving adoption.
Regional Digital Banking Expansion
Grab and Singtel's consolidation of Superbank fits into a broader regional strategy to build digital banking businesses across Southeast Asia. Beyond Indonesia, the partners hold stakes in GXS Bank in Singapore and maintain GXBank as a digital bank subsidiary in Malaysia. The strategic playbook adapts to each market's characteristics: while Superbank leverages ecosystem integration, GXS Bank in Singapore acquired small-business lender Validus Capital to expand lending capabilities for small and medium-sized enterprise (SME) customers. For Grab, consolidating a profitable bank creates an additional revenue stream, though the company acknowledged that integration carries execution and operational risks.
