U.S. dollar rose against a basket of major currencies on reduced worries over the Federal Bureau of Investigation's investigation of emails linked to Hillary Clinton's use of a private server. Persistently low Japanese government bond yields also boosted the greenback. dollar suffered its worst fall in more than seven weeks on Friday following news that the FBI is reviewing fresh evidence in its probe of the Democratic presidential candidate.
"The market is maybe taking a calmer approach to the FBI probe at this point than it was on Friday afternoon," said Shahab Jalinoos, global head of FX strategy at Credit Suisse (SIX:CSGN) in New York.
A Clinton win is generally seen by analysts as likely to be a positive for the dollar, and the FBI announcement on Friday gave new hope to Clinton's Republican rival Donald Trump that he can beat her on Nov. 8.

Deal news, including General Electric (NYSE:GE)'s GE.N merger of its oil and gas business with Baker Hughes Inc BHI.N and CenturyLink (NYSE:CTL)'s CTL.N acquisition of Level 3 Communications LVLT.N , helped lift investor sentiment on Wall Street.

Dow Jones industrial average .DJI was up 16.67 points, or 0.09 percent, to 18,177.86, the S&P 500 .SPX gained 5.47 points, or 0.26 percent, to 2,131.88 and the Nasdaq Composite .IXIC added 13.32 points, or 0.26 percent, to 5,203.43.
