Chief Executive of HDFC Bank Aditya Puri has admitted that there is more room for banks to lower lending rates. Addressing the NASSCOM summit in Mumbai on Friday, Mr. Puri said factors like inflation and liquidity play a major role in transmission of benefits to customers. <br/><br/>He said, whenever there is surplus liquidity, banks will have to cut rates whether the regulator cuts rates or not. Talking about the idea of setting up a national bad bank, Mr. Puri said anything that can help resolve the perennial bad loans problem is welcome.<br/><br/> Meanwhile, in one of the sharpest comments against independent prepaid wallet companies like Paytm, Chief of HDFC Bank said companies which hold on to customers through cash-backs are loss-making and have "no future".<br/>
