The main focus for forex investors is whether ECB President Mario Draghi will give any indications about future policy whether the bank is poised to taper its bond purchase program. The ECB may postpone any changes to its policy until December market participants are saying.
The Mexican peso, which is closely watched because Mexico is seen as most vulnerable to Republican Donald Trump's economic policy proposals, rose to 18.4555 to the dollar at one point, its highest level since Sept. 8.
The dollar was little changed against its major rivals at 97.925. USD/JPY edged up 0.35 percent to 103.75.
GBP/USD was flat around 1.2285 ahead of British Prime Minister Theresa May's first European Union summit since taking the helm following Britain's June 23 vote to exit the bloc.
