SBI reported its biggest ever quarterly profit on lower bad loan provisions and better asset quality, sending its shares up over 3%. Net profit jumped to 55.83 billion rupees ($785.56-million) in the three months to Dec. 31, from 39.55 billion rupees a year earlier. That missed analysts' estimates for a profit of 63.34 billion rupees, according to Refinitiv-data, due to a higher tax expense.
