The European Central Bank (ECB) may be forced to bolster its monetary stimulus programmes if governments fail to act to boost their economies, board member Benoit Coeure said on Tuesday. "If there is not much taking place on the structural reform front, if there's not much taking place on the fiscal policy front... then the ECB will do more," Coeure told a Geneva panel discussion, Bloomberg News reported. The ECB's governing council is to meet on September 8, after members chose to take no new measures at a July meeting weeks after Britain's shock vote to quit the EU.
