The beleaguered dollar got a shot in the arm from strong US jobs data Friday, with equities also pushing ahead as investors welcomed the unequivocal signs of American economic strength.

The world's largest economy added 209 000 net new positions in July, well above forecasts, driving the unemployment rate down to 4.3%, a 16-year low.

The data possibly gives the Federal Reserve a clear shot at raising rates after months of inflation weakness clouding the outlook, dealers said, although some noted that wages are still not rising fast enough for comfort.

"The July jobs report from the US appeared to tick all the boxes when the numbers were released, strong jobs gains, higher participation and unemployment back at 16-year lows," said Craig Erlam, senior market analyst at Oanda.

"But as ever, there was one crucial component missing," he cautioned, "the path back to higher earnings continues to be a painfully slow one. The (workers') earnings numbers for June were once again the only disappointment in an otherwise stellar report."

Good enough for Fed?

But others were less reticent. "Strong wage growth is key takeaway today," ING Economics said. "Throw in decent inflation next week and markets might start tentatively re-aligning with Fed dots."

One strong jobs report may not however be enough to sway sceptical investors trying to second-guess the US central bank, they said.

The employment data temporarily dispelled gloom triggered by a report on a probe into alleged Russian interference in the US election.

They also helped European equities extend early tentative gains ahead of the weekend, as newly found dollar strength took the pressure off the euro whose recent rise has been threatening to undermine the competitiveness of eurozone exporters.

But fundamentals are still in favour of the European single currency, many believe.

"The eurozone is today seen by many as a zone of stability," Philippe Waechter, an economist at Natixis, told AFP.

Summer of euro love

The remarkable recovery of the euro against the dollar, which shortly after Donald Trump's election threatened to reach parity with its European rival, has sparked praise bordering on the emotional.

"Investors are totally in love with the euro at the moment - it's come from a very cheap level and taken on a momentum of its own," William Hamlyn, investment analyst at Manulife Asset Management, told AFP.

"There's a general nervousness that this strong euro is beginning to impact European corporate profits - we are starting to see it in this quarter's results," he said.

Wall St also held on to small early gains approaching midday, possibly heading for an eight straight closing gain, but political worries weighed heavily on US investors.

Overnight, the revelation by the Wall Street Journal that special counsel Robert Mueller has convened a grand jury to investigate Russia's interference in the 2016 presidential election - a step towards possible criminal indictments - sparked a furious reaction from President Donald Trump and dented gains on Wall Street.

The report sent the European single currency surging on Wednesday to $1.1910 - its highest level since early January 2015. By the later afternoon in Europe Friday, the euro had retreated to $1.1761.
