Investors also watched for market reaction to comments by U.S. Federal Reserve Chairman Jerome Powell vowing tough action on inflation.
Fed Chair Powell said Monday that inflation is "much too high," with the central bank set to "take the necessary steps to ensure a return to price stability."
"In particular, if we conclude that it is appropriate to move more aggressively by raising the federal funds rate by more than 25 basis points at a meeting or meetings, we will do so," Powell said.
Those comments came less than a week after the central bank raised interest rates for the first time in more than three years.
Powell's messaging "could not be clearer," according to National Australia Bank's Ray Attrill.
"The US Fed Funds futures now has 42bps of tightening priced for May up from 3.5bps at Friday's close, and 80bps over the combined May-June meetings, so now flirting with the notion of back-to-back 50 point increases," Attrill said.
