The euro touched an eight-week low against the dollar, while the Swiss franc fell to a seven-week trough. Speaking at a virtual meeting of the London-based Official Monetary and Financial Institutions Forum, Chicago Fed President Charles Evans said the U.S. economy risked a longer, slower recovery, if not an outright recession without another fiscal support package. Evans also said he does not see open-ended quantitative easing as providing an important part of the answer. Evans is not a voter at the Federal Open Market Committee this year , but he will be in 2021. "Evan"s comments were extremely hawkish. He mentioned pausing QE and rates rising before the inflation target is reached. That kind of surprised the market," said Edward Moya, senior market analyst at OANDA in New York. "The sooner we get to the other side of this virus, you"re going to see rate hike expectations jump up and that should further drive this dollar rebound." The dollar climbed in earlier trading after parts of Europe imposed new restrictions aimed at curbing surging coronavirus cases. Meanwhile Fed Chair Jerome Powell told a congressional panel on Tuesday that while America"s economy has shown "marked improvement" since the coronavirus pandemic drove it into recession, the path ahead remains uncertain and the U.S. central bank will do more if needed. In midday trading, the dollar was last up 0.47% at 94.027 versus a basket of currencies. It hit a high of 94.086, its strongest level since late July. The euro was down 0.6% against the dollar at $1.1703, after falling below a key $1.17 level, its lowest since late July as well. The dollar also gained against the yen, rising for a second day in a row. It was last up 0.38% at 105.04 yen. ======================================================== Currency bid prices at 12:13PM (1613 GMT) Description RIC Last U.S. Close Pct Change YTD Pct High Bid Low Bid Previous Change Session Euro/Dollar EUR= $1.1703 $1.1769 -0.56% +4.40% +1.1773 +1.1693 Dollar/Yen JPY= 105.0400 104.6400 +0.38% -3.51% +105.0700 +104.4100 Euro/Yen EURJPY= 122.95 123.17 -0.18% +0.82% +123.2700 +122.6600 Dollar/Swiss CHF= 0.9201 0.9143 +0.63% -4.93% +0.9203 +0.9138 Sterling/Dollar GBP= 1.2731 1.2814 -0.65% -3.98% +1.2866 +1.2712 Dollar/Canadian CAD= 1.3311 1.3306 +0.04% +2.51% +1.3345 +1.3283 Australian/Doll AUD= 0.7173 0.7223 -0.69% +2.18% +0.7235 +0.7165 ar Euro/Swiss EURCHF= 1.0770 1.0762 +0.07% -0.76% +1.0772 +1.0746 Euro/Sterling EURGBP= 0.9193 0.9183 +0.11% +8.75% +0.9220 +0.9145 NZ NZD= 0.6635 0.6666 -0.47% -1.50% +0.6687 +0.6633 Dollar/Dollar Dollar/Norway NOK= 9.3513 9.2791 +0.78% +6.53% +9.3677 +9.2725 Euro/Norway EURNOK= 10.9460 10.9300 +0.15% +11.26% +10.9880 +10.9135 Dollar/Sweden SEK= 8.9039 8.8414 +0.09% -4.74% +8.9132 +8.8403 Euro/Sweden EURSEK= 10.4232 10.4134 +0.09% -0.44% +10.4300 +10.3845 (Additional reporting by Gertrude Chavez-Dreyfuss in New York; Editing by Jonathan Oatis and Chris Reese)
