What is TMC in the context of a bank — what is it about? Is it some kind of technique or what?

In the banking sector, TMC stands for 'material and tangible assets.' These are not equipment but physical resources that the bank uses in its activities: office furniture, computers, stationery, consumables, and other physical assets that need to be accounted for and controlled. In banking accounting and management, TMC refers to accounting objects for inventory and expense control.
