伊朗外交部：美國對地區局勢惡化負有全部責任。

The dollar could fall if Federal Reserve Chair nominee Kevin Warsh leans in favor of interest rate cuts in his Senate hearing later, ING's Chris Turner says in a note. "With oil prices and short-term inflation expectations high at the moment, comments which see short-dated swap rates and real rates [adjusted for inflation] come lower will be dollar negative." Any dollar reaction is unlikely to be significant, however, as Republican Senator Thom Tillis could prevent the Warsh nomination from proceeding to a full vote in the Senate amid an investigation into the Fed's reconstruction project, he says.
