The bank said that it proposed the acquisition of Bank Mestika in October 2009, and is still waiting for approval from the Indonesian regulator to acquire 80% stake in Bank Mestika for MYR1.16bn ($378m).

RHB Capital chief executive Kellee Kam said that the bank has been in active dialogue with the (Malaysian) central bank throughout.

"Once we cross June, if we haven’t gotten sufficient indication that the transaction will close, the board will take a step back and speak again about what we’re going to do with the transaction," Kam said.

RHB Capital said that it is also awaiting regulatory approval for a separate acquisition deal involving the investment banking arm of OSK Holdings.

Upon the successful completion of the long awaiting merger, RHB Capital will become the country’s largest brokerage by market share.
