With Fed policymakers expected to forecast the fastest U.S. economic growth in decades in the wake of COVID-19 vaccinations and $1.9 trillion in new stimulus, market participants will be focused on clues that the central bank could start raising rates in 2023, earlier than it had said. "The spike in U.S. yields dictated the positioning before the Fed," said Edward Moya, senior market analyst, at online FX broker OANDA. "The market is anticipating a much more optimistic outlook by the Fed and with that you"re going to get higher Treasury yields, and that would be supportive for the dollar," he added. The U.S. benchmark 10-year note yield rose to a 13-month peak of 1.676% and was last up at 1.655%. Ahead of the Fed statement later on Wednesday, eurodollar futures, which track short-term rate expectations, have priced a 90% chance of a rate hike by December 2022, with three hikes seen in 2023. In mid-morning trading, the dollar index was flat at 91.865. The euro was up 0.1% at $1.1912, after declining in the past three sessions. Hurt by a possible delay in the European Union"s vaccination effort, the euro seemed set to test last week"s 3-1/2-month low of $1.1835. Europe"s medicines watchdog will release results of its investigation into incidents of bleeding, blood clots and low platelet counts in recipients of AstraZeneca"s coronavirus vaccine on Thursday afternoon. Europe"s painful recovery from the pandemic is in sharp contrast with other economies, which seem less dependent on monetary stimulus to pull though. The Bank of Canada for instance is likely to reduce its bond purchases as soon as next month, strategists say. The rouble fell 1.3% against the greenback to 73.78 per dollar, after U.S. President Joe Biden said Russian President Vladimir Putin would face consequences for directing efforts to swing the 2020 U.S. presidential election to Donald Trump. Against the yen, the greenback firmed 0.2% to 109.17 yen, hovering near nine-month highs hit this week. The British pound was flat at $1.3896%, recovering from profit-taking after it hit a near three-year high last month on the back of a fast vaccine roll-out. Commodity-linked currencies including the Australian dollar, the New Zealand dollar and the Canadian dollar traded lower against the U.S. dollar. In the cryptocurrency market, bitcoin fell 3.4% to $54,978.00, slipping further away from a record high of $61,781.83 hit on Saturday. ======================================================== Currency bid prices at 10:44AM (1444 GMT) Description RIC Last U.S. Close Pct Change YTD Pct High Bid Low Bid Previous Change Session Dollar index 91.8880 91.8730 +0.03% 2.119% +91.9930 +91.8180 Euro/Dollar $1.1910 $1.1903 +0.06% -2.52% +$1.1917 +$1.1887 Dollar/Yen 109.1800 109.0200 +0.14% +5.69% +109.2450 +109.0650 Euro/Yen 130.02 129.75 +0.21% +2.44% +130.0500 +129.7200 Dollar/Swiss 0.9277 0.9248 +0.32% +4.87% +0.9296 +0.9248 Sterling/Dollar $1.3892 $1.3895 +0.00% +1.71% +$1.3929 +$1.3880 Dollar/Canadian 1.2476 1.2448 +0.22% -2.03% +1.2479 +1.2434 Aussie/Dollar $0.7721 $0.7746 -0.32% +0.37% +$0.7747 +$0.7711 Euro/Swiss 1.1049 1.1007 +0.38% +2.22% +1.1061 +1.1006 Euro/Sterling 0.8572 0.8567 +0.06% -4.08% +0.8573 +0.8541 NZ $0.7169 $0.7190 -0.28% -0.15% +$0.7194 +$0.7158 Dollar/Dollar Dollar/Norway 8.5020 8.4700 +0.16% -1.21% +8.5125 +8.4785 Euro/Norway 10.1257 10.0967 +0.29% -3.26% +10.1330 +10.0840 Dollar/Sweden 8.5070 8.4960 +0.27% +3.81% +8.5298 +8.4968 Euro/Sweden 10.1333 10.1058 +0.27% +0.56% +10.1465 +10.1140 (Reporting by Gertrude Chavez-Dreyfuss; Additional reporting by Julien Ponthus and Marc Jones in London; Editing by Giles Elgood and Andrea Ricci)
