Though a potential global financial crisis was averted at the last minute, one notable development has been a string of warnings by Chinese officials. Prime Minister Li Keqiang told Secretary of State John Kerry that he was “highly concerned” about a possible default. Yi Gang, deputy governor of China’s central bank, warned that America “should have the wisdom to solve this problem as soon as possible.” An opinion essay in Xinhua, the state-run media agency, called “ for the befuddled world to start considering building a de-Americanized world.” These statements, unusually blunt coming from the Chinese, show that repeated, avoidable crises threaten the privileged position of the U.S. as issuer of the world’s main reserve currency and (until now) risk-free debt.
