DXY BULLISHU.S. Dollar Currency IndexTVC:DXYOsamudiamehThe dollar advanced against the euro and sterling on Wednesday but investor concerns over the Federal Reserve's independence continued to linger, potentially limiting the U.S. currency's rise. The euro EURUSD was down about 0.4% at $1.1593 and sterling GBPUSD slipped 0.3% to $1.3441, giving back some of the gains spurred by Trump's announcement on Monday that he would fire Fed Governor Lisa Cook over alleged improprieties in obtaining mortgage loans. Cook's lawyer later said she would file a lawsuit to prevent her ouster, kicking off what could be a protracted legal fight. Trump's unprecedented bid to remove the Fed Governor adds to the relentless pressure he has put on the central bank to lower interest rates since he returned to the White House this year.
