European markets opened lower on Thursday after US Federal Reserve Chairman Ben Bernanke made it clear that there was no predetermined timeline for reducing US monetary stimulus.
The Stoxx Europe 600 index opened 0.3% lower at 296.31. Britain's FTSE 100 and Germany's DAX opened 0.2% lower each.
France's CAC 40 index opened 0.3% lower, while Spain's IBEX 35 was down 0.17% and Italy's FTSE MIB was down 0.34%.
In his bi-annual testimony to the House Financial Services Committee, Bernanke said that "with unemployment still high and declining only gradually, and with inflation running below the Committee's longer-run objective, a highly accommodative monetary policy will remain appropriate for the foreseeable future.
"We anticipated that it would be appropriate to begin to moderate the monthly pace of purchases later this year," Bernanke continued - albeit provided that incoming US economic data shows a strengthening labour market and inflation moving back toward the central bank's 2% target.
Market participants will be tracking Bernanke's testimony to the Senate Banking Committee, which is due later in the day.
