Southeast Asian Banks with the Highest Revenue in 2026

Southeast Asia is home to some of the world's most dynamic and rapidly growing financial institutions. Driven by expanding economies, increasing digital adoption, and rising consumer demand for financial services, the region's leading banks continue to strengthen their positions both domestically and internationally.

Based on revenue in 2026, Singapore, Indonesia, Malaysia, and Thailand dominate the list of Southeast Asia's largest banks.

Leading the ranking is DBS Group Holdings of Singapore, which generated an impressive revenue of $28.26 billion. As the largest bank in Southeast Asia by revenue, DBS has built a strong reputation for innovation, digital banking excellence, and regional expansion. Its extensive presence across Asia has helped it maintain a significant competitive advantage.

In second place is Singapore's Oversea-Chinese Banking Corporation (OCBC), with revenue of $20.37 billion. OCBC remains one of the region's most established financial institutions, offering a broad range of banking, wealth management, and insurance services.

Close behind is Indonesia's Bank Rakyat Indonesia (BRI), which recorded revenue of $20.12 billion. BRI's strong focus on microfinance and small-business lending has made it one of Indonesia's most influential financial institutions.

Another Singaporean giant, United Overseas Bank (UOB), ranks fourth with revenue of $19.29 billion. Together, DBS, OCBC, and UOB highlight Singapore's status as one of Asia's premier financial centers. Malaysia's largest bank, Maybank, follows in fifth place with revenue of $15.57 billion, reflecting its strong regional presence and diversified banking operations.

Indonesia's Bank Mandiri secured sixth position with revenue of $12.99 billion. As one of the country's leading state-owned banks, Bank Mandiri plays a critical role in supporting Indonesia's economic development and infrastructure financing.

Malaysia's CIMB Group Holdings ranked seventh with $8.80 billion in revenue, maintaining a significant footprint across Southeast Asia.

Thailand is represented by two major institutions in the top ten. Kasikornbank generated $8.17 billion in revenue, placing eighth, while Bangkok Bank followed closely with $7.97 billion. Both banks continue to benefit from Thailand's strong commercial and international trade sectors.

Rounding out the list is Indonesia's Bank Central Asia (BCA), which recorded revenue of $7.73 billion. Widely recognized for its strong profitability and customer service, BCA remains one of Indonesia's most respected private-sector banks.

Together, these ten institutions demonstrate the strength and diversity of Southeast Asia's banking sector. Their continued growth reflects the region's increasing economic importance and its emergence as one of the world's most significant financial markets.
