Euro zone bond yields were little changed on Thursday as concerns persisted ‍over the strength of ‍the euro and whether it might prompt the European Central Bank ​to ease policy, while the U.S. Federal Reserve kept rates on hold. Shorter-dated euro zone yields had retreated on Wednesday, with the German two-year ⁠slipping to ‌its lowest level in a week. As the euro zone is a net energy importer, even modest currency gains can reduce the cost of energy and other imports, potentially lowering inflation. ECB policymaker Martin Kochertold the Financial ⁠Times that further euro appreciation could ​force the central bank to cut rates. He added that rising oil prices were offsetting the euro’s strength.
