The dollar index hovered around 99.6 on Monday after a sharp advance in the previous session, as hawkish comments from Federal Reserve Chair Kevin Warsh prompted traders to ramp up bets on an imminent interest rate increase.

Futures markets now assign roughly a 57% probability that the Fed will raise rates by 25 basis points in September, up from about 40% a week earlier. The dollar also drew support from a surprise upward revision to the University of Michigan’s consumer sentiment index.
