The number of Americans filing for unemployment benefits fell to near a 43 year-low last week, pointing to further tightening in the US labour market. 

Initial claims for state unemployment benefits dropped 28,000 to a seasonally adjusted 235,000 for the week ended December 31, the Labor Department said today. 

That was close to the 233,000 touched in mid-November, which was the lowest level since November 1973. 

Claims for the previous week were revised to show 2,000 fewer applications received than previously reported.

But with claims data for six states and one territory estimated because of the New Year's holiday, last week's drop likely exaggerates the labour market's strength.  

The four-week moving average of claims, considered a better measure of labour market trends as it irons out week-to-week volatility, fell 5,750 to 256,750 last week. 

In a second report, payrolls processor ADP said private employers added 153,000 jobs in December after increasing their payrolls by 215,000 in November. The ADP national employment report is jointly developed with Moody's Analytics.

Initial US jobless claims have now been below 300,000, a threshold associated with a healthy labour market, for 96 consecutive weeks. That is the longest stretch since 1970, when the labour market was much smaller.  

The US labour market is considered to be at or near full employment, with the jobless rate at a nine-year low of 4.6%. 

Tightening labour market conditions and gradually firming inflation allowed the US Federal Reserve to raise its benchmark overnight interest rate last month by 25 basis points to a range of 0.5% to 0.75%. 

While the US Fed forecast three rate hikes for 2017, minutes of the December 13-14 policy meeting released last night suggested the pace of increases would largely be determined by the labour market and fiscal policy. 

Economists polled by Reuters had forecast first-time applications for jobless benefits falling to 260,000 in the latest week. 

Claims briefly pushed higher last month and in November, but economists blamed the gyrations on difficulties adjusting the data around moving holidays.

A Labor Department analyst said there were no special factors influencing last week's data. 

That data has no bearing on December's employment report, which is scheduled for release on Friday, as it falls outside the survey period. 

According to a Reuters survey of economists, non0farm payrolls likely increased by 178,000 jobs in December after the same gain in November. 

Meanwhile, a third report from global outplacement consultancy Challenger, Gray & Christmas said US-based employers announced plans to cut 33,627 jobs from payrolls last month, up 25% from November. 

But that was still below the monthly average of 43,910 job cuts for 2016. 

Layoffs last month were led by the defence, automotive, energy, transportation and government sectors. Employers announced 526,915 layoffs last year, down 12% from 2015.
