NEW YORK/LONDON, July 9 (Reuters) - Equity markets slid on Thursday after U.S. data raised worries about the economy’s recovery and doused enthusiasm that drove a Chinese stock rally for an eighth straight day, while the dollar rebounded as new coronavirus cases hit another record.
The dollar had struggled earlier in the session, with China’s yuan climbing to a four-month peak, as investors poured into Chinese stocks on growing signs of a recovery that also helped lift copper prices to more than a year high.
But concerns about renewed U.S. coronavirus lockdowns kept a lid on oil prices, too, and offset signs of a pick-up in U.S. fuel demand. A slowing rate of decline in weekly U.S. jobless claims from a peak in March also gave investors pause.
Rising coronavirus cases and slower improvement in the U.S. jobs market amounted to a one-two punch for investors.
“We are reaching the levels of unemployment which are likely to persist until a more true re-opening can occur, either with a vaccine, novel treatment, or time,” said Jamie Cox, managing partner at Harris Financial Group in Richmond, Virginia.
The MSCI world equity index, which tracks shares in 49 nations, retreated after earlier gains. The index fell 0.26% after its broadest measure of Asia-Pacific shares outside Japan rose 0.85% on the China rally.
Wall Street also mostly fell, but the red-hot tech sector roared ahead, on track for its fifth closing record high in six sessions. The Dow Jones Industrial Average slid 1.16% and the S&P 500 lost 0.41%. The Nasdaq Composite added 0.58%, led by Amazon.com.
In Europe, stocks pared gains to close lower. Europe’s broad FTSEurofirst 300 index dropped 0.78%.
More than 60,000 new coronavirus infections were reported on Wednesday and U.S. deaths rose by more than 900 for a second straight day, the highest since early June.
Jobless claims have been gradually falling, though they remained roughly double their highest point during the 2007-09 Great Recession.
Initial claims for state unemployment benefits totaled a seasonally adjusted 1.314 million for the week ended July 4, down from 1.413 million the prior week, the Labor Department said.
Oil prices fell about 3% as investors worried that renewed U.S. lockdowns to contain the spread of coronavirus would sap fuel consumption.
“COVID-19 cases continue to increase in the U.S. and traders wonder when they will see an end of this, when the trend will change,” said Louise Dickson, oil markets analyst at Rystad Energy.
Brent crude futures settled down 94 cents at $42.35 a barrel. U.S. crude futures slid $1.28 to settle at $39.62 a barrel.
Overnight in Asia, Chinese stocks saw their longest winning streak in two years, and the yuan had strengthened past 7% , despite rising tension over Hong Kong and the economic uncertainty caused by COVID-19.
It was the Shenzhen blue-chip index’s eighth straight day of gains, adding another 1.5% to its 16% surge this month, and it helped Europe initially on an upward trajectory after hesitation caused by uninspiring German data.
Improving risk sentiment was the dollar’s earlier downward momentum – it was at a one-month low against the euro, a three-week low versus the British pound and a four-month trough against the Swiss franc before rebounding.
Asia’s investors have been riding high after a front-page editorial in Monday’s China Securities Journal that extolled market fundamentals, which was taken as official encouragement to buy stocks.
State-run media warned on Thursday that investors should still pursue rational investments and manage risks, but that did not rein in the bulls.
In Europe though, Britain suffered another 5,000 high street jobs losses and Germany’s export figures recovered less than expected in May as demand remained subdued despite lockdowns being lifted in large parts of Europe.
The dollar index, which tracks the greenback versus a basket of six currencies, rose 0.32% to 96.737.
Gold prices retreated a day after vaulting to nearly nine-year highs. U.S. gold futures settled down 0.9% at $1,803.80 an ounce.
