The financial sector in Malaysia is anchored by five dominant domestic banking institutions that command the vast majority of total industry assets, widespread branch networks, and retail customer accounts. These premier institutions comprise Malayan Banking Berhad (Maybank), CIMB Group Holdings, Public Bank Berhad, RHB Bank, and Hong Leong Bank. Each of these financial heavyweights plays a critical role in driving national economic development, offering comprehensive commercial retail banking, corporate finance, investment services, and Islamic banking solutions across Southeast Asia.
