LONDON (Reuters) - The dollar recovered from 12-week lows but was poised for a fourth straight weekly loss in cautious trading on Friday ahead of U.S. payrolls data while a set of healthy corporate results underpinned gains across European equity markets.
Earlier in the day, an unexpected tightening of policy by China's central bank put Asian markets, already on the back foot on growing concerns about U.S. President Donald Trump's aggressive policies, under further pressure.
While a set of well-received corporate results helped prevent the weakness from spilling over into European stocks, the focus now shifts to the U.S. labour market report, which comes ahead of next week's U.S. Federal Reserve rate decision.
The dollar rose to its session high against a basket of six major currencies, with the dollar index up 0.17 percent to 99.962.
According to a Reuters survey of economists, nonfarm payrolls probably increased by 175,000 jobs last month, picking up from the 156,000 jobs added in December. The unemployment rate is expected to be unchanged at 4.7 percent in January, near a nine-year low.
