The dollar nudges higher, eye Fed Chair Powell's speech

The dollar nudges higher; eye Fed Chair Powell's speech and Yen on intervention watch.

On Tuesday, the U.S. dollar swayed in a tight range as traders took stock of developments in the Middle East and braced for speeches this week by central bank officials, including Federal Reserve Chair Powell, to gauge the policy outlook. Tonight, the US Retail Sales data is considered the key reference.

The yen was pinned close to the key 150 per dollar level, keeping investors on edge for any signs of intervention by the Japanese authorities.
