The Government Savings Bank recently reported profits of Bt10.26 billion for January-July and expects full-year profits to climb to Bt17 billion, from Bt15 billion last year.
Lersak Chuladesa, president and CEO, last week attributed the satisfactory results to increased lending amid the economic recovery.
The GSB would transfer half of the profits to government coffers by year-end, he said.
The bank last year gave about Bt8 billion to the state.
Non-performing loans dropped slightly to 2.16 per cent of total loans from 2.22 per cent last year.
Outstanding loans were Bt922.84 billion, an increase of Bt141.34 billion from last year.
Deposits rose by Bt133.6 billion to Bt1.1 trillion, thanks to the popularity of its lottery-savings product.
Total assets rose to Bt1.22 trillion from last year. The bank aims to open 100 more branches in department stores in order to provide more loans to consumers.
It also runs 390 savings service counters at schools nationwide.
The bank plans to open more savings counters at schools in order to promote a savings culture among pupils.
It will also install 1,000 ATMs in the next six months, to boost its ATM base to 2,200 units nationwide.
Under the government's debt-restructuring scheme for people who owe money to loan "sharks", the bank has lent Bt10.8 billion to 135,000 people, while another 50,000 loan applications are awaiting approval.
The bank has said it will support the government's new project to help people rein in their debts through its People's Bank.
Anyone who wants to refinance his or her debts can apply for a loan under the scheme, for up to Bt100,000. As of last month, 550,000 persons had borrowed Bt20 billion from the People's Bank.
The GSB also plans to upgrade 3,000 revolving village funds to community banks within three years. About 100 villages could run their own banks now, Lersak said.
The bank had provided Bt1 million to each of 60,000 villages countrywide under a populist policy initiated by the Thaksin government.
