PRAGUE (Reuters) – The Czech National Bank’s board did not have a big discussion at its last meeting on selling part of the central bank’s foreign exchange reserves for monetary policy purposes, Governor Jiri Rusnok said on Friday. The bank however decided to increase volumes of sales of income on invested foreign exchange reserves to limit growth of its balance sheet, a programme that is not meant as policy tool.
