Credit expanded by 0.3% or 1.2 billion baht from the end of 2012 during the quarter, said CEO Boontuck Wungcharoen in a statement on Thursday.
The policy interest rate cut narrowed its net interest margin to 2.87% from 2.95% in the same quarter of last year. Net interest income, however, rose by 6%.
Its non-performing loan ratio was steady at 3.85% while its coverage ratio was at 138%.
The bank revised down its credit growth to 6-8%.
Non-interest income fell by 10% year-on-year, largely due to shrinking mutual fund fees in the wake of slowing demand and lower credit fees while trade finance fees slightly improved, he said.
Operating income therefore rose by 1%, failing to offset a regular increase in expenses.
Deposits grew by 5.5% to 29 billion baht during the quarter, he said.
TMB's largest shareholders as of the latest shareholder register book closing date on March 10 were the Finance Ministry (26.06%), and the Dutch bank ING Bank NV (25.16%).
TMB shares closed Friday's morning session at 2.42 baht, down two satang, in trade worth 200.86 million baht.
