Markets now expect a 53% chance of a 25-basis point cut, according to CME Group's FedWatch Tool, down from more than 61% earlier in the day, while that of a 50 bps cut stands at 47%.

"(The report) will do little to allay lingering concerns over the health of the U.S. labor market," said Michael Brown, senior research strategist at Pepperstone.
