This is the first time Maybank has topped 12 categories of the Euromoney Awards in Malaysia, said Head of Community Financial Services Malaysia Datuk Hamirullah Boorhan in a statement.
He added the recognition reinforced Maybank's position as Malaysia's leading wealth management provider in terms of service and product offerings.

"Today, we are among the leaders in this business in Southeast Asia with total assets under management averaging a growth rate of 14.33 per cent the last five years," he said.
Hamirullah also said wealth management was a key component of Maybank's retail banking business with growth's annual average rate of about 10 per cent over the last five years.
He said Maybank's premium banking services were currently present in Malaysia, Singapore, Indonesia, Philippines, Cambodia and Brunei.
