Dollar hits one-month high on lingering Fed hike chance

The U.S. dollar held at a one-month high on Tuesday as traders weighed a slim but lingering chance of a Federal Reserve rate hike, despite falling oil prices easing inflation concerns. The dollar index edged up to 101.55, with markets pricing in an 81% chance of a hike by September. The Bank of England and Bank of Japan are widely expected to keep rates unchanged this week.
