Overall, As of 31 March 2015,[update] SBT had a network of 1,157 branches and 1,602 ATMs, covering 18 states and three union territories.

On 15 February 2017, the Union Cabinet approved a proposal to merge SBT and four other associate banks with SBI.

Following popular resentment against his dictatorial rule, the bank never credited his role.

Instead, the Bank considered the Maharaja of Travancore Sri Chithira Thirunal Balarama Varma as the founder, though the king had little to do with the founding.

Between 1959 and 1965, SBT acquired numerous small, private banks in Kerala.
