Reserve Bank governor Shaktikanta Das on Friday cautioned banks against any build-up of asset-liability mismatches, saying both are detrimental to financial stability and hinted that the ongoing crisis in the US banking system seems to have emanated from such mismatches. Delivering the annual KP Hormis (Federal Bank founder) commemorative lecture in Kochi this evening, the governor was quick to acknowledge and assure that the domestic financial sector is stable and the worst of inflation is behind us.
