Reserve Bank of India (RBI) Governor Shaktikanta Das on Friday warned banks of "structural liquidity issues", if deposit growth continues to trail credit growth. Das also flagged more issues on the unsecured credit front, pointing out that banks are having higher ceilings for such risky credit despite the portfolios being large enough, and asked them to be prudent and avoid exuberance. Urging banks to maintain a "reasonable balance" between credit and deposit growth, Das also mentioned that a good part of household savings that used to come into the banking system as deposits is now going into other instruments like mutual funds. "Credit growth should not run ahead of deposit growth by miles. More so when banks are required to maintain CRR, SLR, LCR," Das said during his address at a summit organised by Financial Express here. "Deposit mobilisation has been lagging credit growth for some time now. This may potentially expose the system to structural liquidity issues," he added. He
