With public sector banks losing share of current and savings account business, finance minister Nirmala Sitharaman has asked state-run bank chiefs to focus on innovative deposit instruments so that they can raise lower-cost resources to meet their financing requirements. The minister once again flagged the issue at a meeting with public sector bank chiefs on Saturday with sources saying that she wanted the lenders to focus on their “core activity”. Some of the new generation private banks, for instance, are offering over 9% on certain tenures of term deposits.
