BANGKOK - World shares sagged Monday as reports of new coronavirus infections in the U.S. and worldwide surged, with the global total approaching 9 million.

European markets opened lower after a mixed session in Asia.

Britain's FTSE 100 lost 0.3% to 6,275.24. The CAC 40 in Paris edged 0.2% lower to 4,967.73, while Germany's DAX slipped 0.1% to 12,315.63. U.S. futures augured a strong start to the week, with the contracts for both the S&P 500 and the Dow up 0.8%.

Sydney's S&P/ASX 200 was almost unchanged at 5,944.50, supported by a report that consumer spending has rebounded more quickly from the pandemic shock than expected, analysts said.

“However, that partly reflects pent-up demand and the strong support from government initiatives. Employment income has slumped and we only expect spending to return to pre-virus levels next year,” Marcel Thieliant of Capital Economics said in a report.

Tokyo's Nikkei 225 index slipped 0.2% to 22,437.27, while the Hang Seng in Hong Kong sank 0.5% to 24,515.23. The Kospi in South Korea slipped 0.7% to 2,126.73.

The Shanghai Composite index edged 0.1% lower to 2,965.27, while India's Sensex jumped 0.9%. Shares rose in Taiwan and Singapore but fell in Jakarta and Bangkok.

Investors appear cautious with prices already relatively high and “out of whack" with earnings expectations, Mizuho Bank said in a commentary. “And so, investors may be increasingly nervous about being caught on the wrong side of ‘irrational exuberance,' “ it said.

On top of that, the “sheer speed and amplitude of the equity market rebound ... from the depths of the March sell-off may also counsel some patience rather than haste; prudently pausing to take profits for the quarter," it said.

The World Health Organization on Sunday reported the largest single-day increase in coronavirus cases by its count, at more than 183,000 new cases in the previous 24 hours. The UN health agency said on Sunday that Brazil led the way with 54,771 cases and the US next at 36,617. India confirmed 15,400 new cases.

The United States also reported more than 30,000 new coronavirus cases on Friday and Saturday, with the daily totals their highest since May 1. A large share of the cases are in the South, West and Midwest, where hospitals in some areas are becoming overwhelmed.

Case numbers in South Korea and China have appeared to be moderating after recent outbreaks centred in their capitals.

Great uncertainty remains over whether countries that have been relaxing pandemic-fighting restrictions on travel and business might end up re-imposing broader controls that would slow a recovery from the worst global downturn since the Great Depression in the 1930s.

“The extent to which the COVID-19 pandemic slows economic recovery could increasingly come into focus. These shifting dynamics are always challenging to equate," Stephen Innes of AxiCorp said in a commentary.

On Friday, the S&P 500 ended a wobbly day down 0.6% at 3,097.74 after mounting worries about the rising coronavirus infections undercut an early rally.

The simultaneous expiration of contracts for stock options and futures, an occasional occurrence that can drive bouts of buying and selling and is known as “quadruple witching day," added to volatility.

Even if widespread stay-at-home orders don’t happen, the fear is that scared shoppers may still shy away from stores and businesses may pull back on their own spending.

The yield on the 10-year Treasury note was steady Monday at 0.70% after climbing as high as 0.74% on Friday. It tends to move with investors’ expectations for the economy and inflation.

A barrel of U.S. crude oil for delivery in July gained 6 cents to $39.81 per barrel in electronic trading on the New York Mercantile Exchange. It rose 2.3% to settle at $39.75 on Friday.

Brent crude, the international standard, picked up 15 cents to $42.34 per barrel.

In currency trading, the U.S. dollar was at 106.94 Japanese yen, up from 106.87 on Friday. The euro rose to $1.1214 from $1.1178.
