TOKYO, Feb 15 (Reuters) - The dollar stood tall on Wednesday after Federal Reserve Chair Janet Yellen signalled a faster pace of U.S. interest rate increases at her two-day testimony before Congress.
Yellen told the U.S. Senate Banking Committee the central bank will likely need to raise interest rates at one of its upcoming meetings, although she expressed caution amid considerable uncertainty over economic policy under the Trump administration. dollar index .DXY , which measures the greenback against its six major peers, rose to a 3-1/2-week high of 101.38 on Tuesday following Yellen's remarks. The index was last up 0.1 percent at 101.27.
"Investors didn't expect Yellen to be that hawkish, so the dollar gained," said Ayako Sera, market strategist at Sumitomo Mitsui Trust Bank.
"There are no big factors preventing the Fed from raising rates in March. Unless the emerging markets become volatile or the U.S. economic data shows weakness, the March rate hike is highly plausible," added Sera.

"Changes in fiscal policy or other economic policies could potentially affect the economic outlook," said Yellen, underscoring the uncertainty over economic policy.
