NEW YORK (MarketWatch) -- The dollar fell against the euro Monday as investors looked ahead to speeches from Federal Reserve officials and U.S. retail sales later this week."In an environment quickly morphing back to one indicative of market participants reducing their expectations for a QE3 taper...the U.S. Dollar not only stands to suffer, but 'risk' in general is happily picking up the pieces," said Christopher Vecchio, currency analyst at DailyFX, in a note. The euro EURUSD +0.24% rose to $1.3515 from $1.3493 late Friday, while the dollar fell to ¥100.08 from ¥100.19. The ICE dollar index DXY -0.21% , a measure of the greenback's strength against major rivals, fell to 80.706 from 80.824 late Friday.
