LONDON (Reuters) - The dollar rose to an almost one-month high on Friday, after U.S. economic data highlighted a still-tight labour market that could mean the Federal Reserve keeps hiking interest rates aggressively.
The number of Americans filing new claims for jobless benefits dropped to a three-month low last week while layoffs fell 43% in December, data on Thursday showed.
A separate report also showed that private employment increased by 235,000 jobs last month, far exceeding expectations for a 150,000 increase.
Against a basket of currencies, the U.S. dollar index rose 0.3% to 105.45, having briefly touched a four-week peak of 105.52.
The index was on track for a weekly gain of almost 1.9%, its largest since September.
"Strong labour market data means the narrative that the Fed can keep hiking interest rates is alive," said Giles Coghlan, chief market analyst at HYCM.
"That's why we saw the reaction in the dollar to the positive labour data yesterday," Coghlan added.
Most major currencies were nursing losses on Friday, after the surging greenback knocked them to multi-week lows in the previous session.
Against the Japanese yen, the dollar climbed 0.7% to as high as 134.58 yen, its highest since the Bank of Japan tweaked its yield curve control policy on Dec. 20 last year.
Markets now await the nonfarm payrolls report due later on Friday, with economists polled by Reuters forecasting the U.S. economy to have added 200,000 jobs in December.
"Today, it's exactly the same narrative as yesterday. If the labour market is doing well, then we're likely to see more dollar strength," HYCM's Coghlan said, adding that a payrolls number towards the lower end of expectations could see the dollar weaken and give comfort to the Fed that their hiking cycle is working.
Meanwhile, euro zone inflation tumbled last month but underlying price pressures rose, making it likely the European Central Bank (ECB) will continue tightening policy.
"The drop does not really tell the whole story," said Stuart Cole, head macro economist, Equiti Capital, who highlighted the rise in core CPI to a record 5.2%.
"Today's release does not really change the underlying narrative and will do little to boost hopes that the tightening cycle we are seeing is close to coming to an end," Cole said.
The euro inched down 0.1% to a one-month low of $1.0497, having dropped 0.8% in the previous session.
Elsewhere, sterling was 0.5% lower at $1.1853, its lowest level in over six weeks.
The Aussie was last down 0.2% at $0.6742, after sliding 1.3% in the previous session, reversing most of the gains it made earlier in the week on news that China has eased its restrictions on coal imports from Australia.
The New Zealand dollar was down 0.2% at $0.6210, following a 1% slump on Thursday, and was on track for a weekly loss of over 2%, its biggest weekly fall since September.
