Fresh concern that China's slowdown will hamper global growth has wiped $2.5 trillion off the value of global equities this year, as the nation's tolerance for a weaker currency is viewed as evidence policy makers are struggling to revive an economy that's the world's biggest user of resources.

Treasuries fluctuated as speculation that China will sell U.S. debt and the prospect of more Federal Reserve interest-rate increases limited the securities' appeal as a haven.
