The Reserve Bank of India's Monetary Policy Committee maintained the key lending rate unchanged at 4 per cent on Friday, holding the rates at existing levels for a third straight review. The RBI governor announced that the decision was taken unanimously and added that the reserve repo rate too was kept unchanged at 3.35 per cent. Amid high levels of inflation and the country's shrinking gross domestic product (GDP), the status quo on monetary policy was as expected by most economists.
