Impact of India's second Covid-19 wave showing on mobility and non-mobility sectors: Nomura SECTIONS Share Synopsis The Nomura India Business Resumption Index (NIBRI) fell to 60 for the week ended May 23, down from 63 a week earlier. This reflected a severe drop in the index, which tracks high-frequency economic indicators such as mobility, power demand and unemployment, to levels seen in June last year after a full recovery in February, Nomura said in a note on Monday. Both mobility and non-mobility sectors of the Indian economy were reflecting the impact of the second wave of Covid-19 and the ensuing lockdowns as business activity continued to plunge further in May, said Japanese brokerage Nomura.
