State Bank of India (SBI) chairman Rajnish Kumar told NDTV on Monday that the current cap on withdrawals from Yes Bank accounts could be lifted "within a week". In an exclusive interaction with NDTV, the SBI chairman said: "I want to assure Yes Bank customers that once we (SBI) step in they shouldn't worry about money... The financial system is sound." His comments come at a time when SBI has committed to invest in the troubled private sector lender, whose board was suspended and withdrawals capped by the Reserve Bank of India (RBI) last week, spooking investors.
