(Adds detail on forex reserves and gold reserve changes in paragraphs 2 and 3) COPENHAGEN, Dec 19 (Reuters) - Finland's central bank has decided to increase its foreign exchange reserves by around 2 billion euros ($2.1 billion) to 9 billion, it said on Thursday. The Bank of Finland said in a statement it would achieve the increase by buying U.S. dollars, but also British pounds and Japanese yen. "Foreign exchange reserves have a key role when it comes to ensuring economic and financial preparedness for dealing with future uncertainties and preparing for crises that could weaken Finland’s external solvency," it said. The central bank said it had also sold 10% of its gold reserves. Following the sale, its reserves amount to 44 tonnes, with a market value of around 3.5 billion euros. It said the sale aimed to strengthen its provisions against higher exchange rate risk.
