The Reserve Bank of India (RBI) on Wednesday took a series of liquidity-boosting and loan-relief measures to aid broad swathes of the economy walloped by the second wave of the covid-19 pandemic. Governor Shaktikanta Das said RBI will make available an on-tap liquidity window of ?50,000 crore, with a tenor of up to three years, under which banks can provide fresh lending support to a wide range of entities, including vaccine makers, importers of vaccines, covid-related drugs and priority medical devices, hospitals, pathology labs, manufacturers and suppliers of oxygen and ventilators, logistics firms and also to patients for treatment. This facility, which will be offered at the repo rate, will be available till 31 March 2022. The steps are likely to help the stressed healthcare industry expand facilities to treat more patients amid the rampaging second wave. With thousands of sick people seeking treatment, hospitals are overwhelmed and are running out of medical-grade oxygen. Vaccin
