Sri Lanka's President Mahinda Rajapaksa (R) and Central Bank Governor Ajith Nivard Cabraal look on during the presentation of the 2012 Central Bank of Sri Lanka annual report, in Colombo April 9, 2013. Sri Lanka's official interest rates are expected to decline during May and June as the borrowing needs of loss-making state-run energy enterprises recede, the island nation's Treasury Secretary P.B. Jayasundera said on Tuesday. The central bank has said the monetary policy stance for this year will be towards easing, but it has kept key policy rates steady since a cut of 25 basis points in December
