Currently around 25 relationship managers provide services and advice to 10,000 wealthy customers; TMB plans to add a further 10 managers by the end of the year.

The private banking business, which opened last year, currently has 10 relationship managers that look after 1,000 clients. The minimum requirement to be a private client is total asset possession of 5-30 million baht ($15,000-$950,000).

“With around three million client accounts, TMB feels there is great opportunity to grow both wealth management and the private banking business. Expansion in these two segments also supports product cross-selling, as the bank's existing ratio is three products per client,” said executive vice president Jumpon Saimala.

The institution, formerly known as The Thai Military Bank, was founded in 1957, originally to provide financial services to military personnel and their families.
