World shares mixed on worries virus may upend recoveries

European shares have opened higher after Asia tracked a retreat on Wall Street

TOKYO -- European shares opened higher Tuesday after Asia tracked a retreat on Wall Street as investors grew jittery over the possibility that surging virus cases could stifle the global economic recovery. Benchmarks rose in Paris and London but fell in Asia. U.S. futures were higher and the yield on the 10-year Treasury dropped to 1.18%. Alarm has been mounting in Japan where, with just three days to go before the Tokyo Olympics open, new coronavirus cases are being found among athletes and non-athletes affiliated with the Games. The Japanese government has repeatedly promised “a safe and secure” Games, but just about 22% of the Japanese population is fully vaccinated.
