WASHINGTON (Reuters) - U.S. private payrolls increased by the most in nearly two years in December, suggesting sustained strength in the labour market despite ongoing financial market volatility.
While other data on Thursday showed the number of Americans filing applications for unemployment benefits increased more than expected last week, the underlying trend in claims remained low. Claims data tends to be volatile around year-end holidays.
Labour market data is being closely watched for signs of whether tightening financial conditions could be impacting on companies' hiring decisions. A sharp stock market sell-off has stoked fears about the economy's health.
The ADP National Employment Report showed private payrolls rose by 271,000 jobs last month after a downwardly revised 157,000 increase in November. Economists polled by Reuters had forecast private payrolls advancing 178,000 last month following a previously reported 179,000 increase in November.
The ADP report, which is jointly developed with Moody's Analytics, was published ahead of the government's more comprehensive employment report for December scheduled for release on Friday.
The ADP report has a spotty record predicting the private-payrolls component of the government's employment report and last month's jump probably exaggerates the strength of the labour market.
"The December ADP data have been especially unreliable because of the challenge of adjusting for 'purging' effects," said Jim O'Sullivan, chief U.S. economist at High Frequency Economics in White Plains, New York.
"December is typically when employers drop from their listings all individuals who have left their firms permanently," he said. "Such workers are dropped from the government data when they are no longer being paid, but some employers keep former employees on their lists for ADP until year-end tax documents have been filed."
According to a Reuters survey of economists, nonfarm payrolls likely increased by 177,000 jobs last month after rising 155,000 in November. The unemployment rate is forecast steady near a 49-year low of 3.7 percent, not too far from the Federal Reserve's forecast of 3.5 percent by the end of 2019.
With the labour market viewed at being at or beyond full employment, the pace of job growth is slowing as employers struggle to find workers. Some of the moderation in employment gains has been attributed to the stock market rout.
The Fed raised interest rates last month for the fourth time in 2018, but forecast fewer rate hikes this year and signalled its tightening cycle is nearing an end in the face of financial market volatility and slowing global growth.
U.S. financial markets were little moved by the data.
In a separate report on Thursday, the Labour Department said initial claims for state unemployment benefits rose 10,000 to a seasonally adjusted 231,000 for the week ended Dec. 29. Data for the prior week was revised higher to show 5,000 more applications received than previously reported.
Economists polled by Reuters had forecast claims increasing to 220,000 in the latest week.
The Labour Department said claims for California and Virginia were estimated last week. Unadjusted claims for both of those states declined last week.
A Labour department official said there was no indication of an increase in filings last week from federal workers furloughed because of a partial shutdown of the government that is now in its second week.
Data on claims filed by federal employees is released with a one-week lag. The shutdown, which started on Dec. 22, was triggered by President Donald Trump's demand for $5 billion (£3.97 billion) in border wall funding.
Some 800,000 employees from the Departments of Homeland Security, Transportation, Commerce and others have been furloughed or are working without pay.
Claims data tends to be noisy around year-end holidays. The four-week moving average of initial claims, considered a better measure of labour market trends as it irons out week-to-week volatility, slipped 500 to 218,750 last week.
