• The dollar extended losses on Tuesday after President Donald Trump's national security adviser Michael Flynn quit, with investors waiting to see whether Federal Reserve Chair Janet Yellen offers clues to the likely pace interest rate increases in her congressional testimony.
The dollar weakened 0.3 percent on the day to stand at 113.43 yen, off Monday's high of 114.17 but well above a 10-week low of 111.59 yen touched a week ago.
The dollar index was down 0.1 percent on the day at 100.84, edging away from Monday's high of 101.11, its highest level since Jan. 20.
• Federal Reserve Chair Janet Yellen goes to Congress on Tuesday for the first time since Republicans took control of the White House and both houses of the legislature with less clarity on the direction of U.S. economic policy than at any time of her three-year tenure.
Possible new taxes on imports and increased infrastructure spending could boost inflation and send the dollar soaring, uncertainties that make it unusually difficult for the Fed to chart a course for interest rate policy.
• Traders are buzzing about whether Fed Chair Janet Yellen will sound a bit hawkish Tuesday and indicate that the Fed could consider raising interest rates at its next meeting in March — three months sooner than most Fed watchers are forecasting. If she does, interest rates could jump and stocks could wobble.
• Oil rose on Tuesday, supported by an OPEC-led effort to cut output, but rising production elsewhere kept prices within the narrow range that has contained them so far this year.
Brent crude futures LCOc, the international benchmark for oil prices, were trading at $55.76 per barrel at 0112 GMT, up 17 cents from their last close.
U.S. West Texas Intermediate (WTI) crude futures CLc, were up 14 cents at $53.07 per barrel.
