SINGAPORE, Nov 7 (Reuters) - The dollar seesawed versus the euro and yen in a volatile session as traders scanned U.S. midterm election results for early insights into the prospect of Congressional gridlock.
The Democratic Party is expected to win control of the U.S. House of Representatives, with the Republicans seen likely to keep their majority in the Senate.
A split Congress may hurt the dollar temporarily: a Democratic win in one or both chambers is likely to be seen as a repudiation of President Donald Trump and the policies which have boosted corporate growth.
“If Congress is split, with the Democrats controlling the House and Republicans the Senate, the prospect of legislative gridlock that would make it difficult for policies such as the President’s middle class tax cut to pass is negative for the U.S. dollar,” said Kathy Lien, managing director of currency strategy at BK Asset Management in a note.
The dollar index, a gauge of its value versus six major peers, lost 0.2 percent to trade at 96.12. The greenback has outperformed most of its key rivals this year, benefiting from a robust domestic economy and higher interest rates, with investors focused on whether the mid-terms could disrupt this stellar run.
The dollar is also likely to be supported by minutes of the last Federal Open Market Committee (FOMC) meeting due out on Thursday, in which the Fed is seen likely to reaffirm its intention to lift its policy rate above 3 percent over the next year.
The euro gained marginally to trade at $1.1440 versus the dollar, off its intraday high of $1.1473. The single currency changed hands about 1.1 percent above this year’s trough of $1.1301 reached on Aug. 15.
The dollar lost 0.07 percent against the yen, to trade at 113.33. Earlier in the session, the yen had strengthened to 112.95.
The Australian dollar traded flat at $0.7246.
The pound was 0.22 percent higher versus the dollar at $1.3124. Earlier in the session sterling hit a three-week high of $1.3142.
Sterling slipped as low as $1.3023 on Tuesday before erasing its losses in volatile trade on growing hopes of a breakthrough Brexit deal. (Reporting by Vatsal Srivastava and Daniel Leusssink. Editing by Eric Meijer)
