The Reserve Bank is likely to maintain status-quo on the key interest rates for the third time in a row in its upcoming bi-monthly policy review despite the US Federal Reserve and the European Central Bank hiking benchmark rates, as domestic inflation is within the RBI's comfort zone, say experts. The borrowing cost which started rising in May last year has stabilised with RBI keeping the repo rate unchanged at 6.5 per cent since February when it was raised from 6.25 per cent.
