US employers hired far more workers than expected in February, pushing the labour market closer to maximum employment, new figures show today.

But rising headwinds from geopolitical tensions could hurt business confidence and slow job growth in the months ahead.

The Labor Department's closely watched employment report's survey of establishments today showed nonfarm payrolls surged by 678,000 jobs last month.

Data for January was revised higher show 481,000 jobs created instead of 467,000 as previously reported.

Economists polled by Reuters had forecast payrolls rising by 400,000. Estimates ranged from as low as 200,000 to as high as 730,000 jobs.

Labour market conditions tightened further, with the unemployment rate falling to 3.8%, the lowest since February 2020, from 4% in January. That was despite more people entering the labour force in the US.

US Federal Reserve Chair Jerome Powell this week described the labour market as "extremely tight".

He said he would support a 25-basis-point interest rate increase at the Fed's March 15-16 policy meeting and would be "prepared to move more aggressively" if inflation does not abate as fast as expected.

Oil prices have surged above $100 a barrel since Russia launched a war against Ukraine last week, invoking a barrage of sanctions against Moscow by the United States and its allies.

"There is plenty of concerning news in the world right now, from the Russia-Ukraine conflict to sky-high inflation," said Sam Bullard, a senior economist at Wells Fargo in Charlotte, North Carolina.

"But the US employment recovery continues to be a bright spot amid the carnage," he added.

In the wake of January's employment report and hot inflation readings, financial markets priced in a half percentage point hike. That is now off the table amid worries about the fallout from the Russia-Ukraine war.

Economists expect as many as seven US rate hikes this year.
