| The 
				recent rise in inflation expectations as investors bet on a 
				post-pandemic economic recovery and the so-called "reflation" 
				trade has lifted U.S. government bond yields. That had fed 
				through to a higher dollar until earlier this month when the 
				greenback resumed its decline.
 Analysts expect Powell, who testifies before Congress at 1500 
				GMT, to provide some reassurance that the Fed will tolerate 
				higher inflation without rushing to raise rates. That might calm 
				bond markets and eventually weigh on the dollar, they said.
 
 "Mr. Powell will very likely reiterate that the Fed is a long 
				way from meeting its goals and that it will likely take some 
				time before "sufficient progress" has been made to taper its 
				bond purchase program," UniCredit analysts said.
 
 The dollar index was last at 90.143, up 0.1% on the day, having 
				earlier fallen to 89.941, its weakest since Jan. 13.

 Positioning data shows investors overwhelmingly betting that a 
				U.S. dollar, which has been dropping since last March, will keep 
				falling as the world recovers from the COVID-19 pandemic.
 
 "Only when the spike in U.S. yields becomes more disorderly and 
				spills forcefully into risk assets, would U.S. dollar experience 
				an across-the-board strength," said ING analysts in a research 
				note.
 
 The euro weakened 0.1% to $1.2151. Euro zone government bond 
				yields have also been rising but the rally took a brief pause 
				after European Central Bank President Christine Lagarde said on 
				Monday the bank was "closely monitoring" rising borrowing costs.
 
 Commodity-linked currencies have been among the best performers 
				in 2021. Surging prices for materials from oil and copper to 
				lumber and milk powder have pushed currencies such as the 
				Canadian, Australian and New Zealand dollars to their highest in 
				roughly three years.
 
 On Tuesday, the Aussie traded down 0.2% at $0.7903 having 
				earlier hit a high of $0.7934. The New Zealand dollar was down 
				marginally while the Canadian dollar was just below its Monday 
				high.
 
 Sterling hit a new nearly three-year high of $1.4098, up 0.3% on 
				the day, as investors stuck with their bets that a rapid rollout 
				of the COVID-19 vaccine would allow the British economy to 
				reopen over the next few months.
 
 Prime Minister Boris Johnson laid out his step-by-step plan for 
				ending the current British lockdown on Monday.
 
 Bitcoin, the world's biggest cryptocurrency, fell sharply below 
				$45,000 and was last down 15% at $45,953, extending its drop 
				from a record set on Sunday of $58,354 as investors grow nervous 
				about sky-high valuations.
 
 The Japanese yen, the worst performing major currency of 2021 
				because rising U.S. Treasury yields can lure investment from 
				Japan, fell again. The dollar was last up 0.2% at 105.26 yen per 
				dollar.
