Summary

  • $87.8 billion of Japan’s foreign securities holdings disappeared in August, strongly indicating Tokyo sold overseas assets to bankroll its latest yen-support operation.
  • Finance Ministry data showed the drop was close to the ¥15.4 trillion, or $98.6 billion, that authorities said they spent in the month through Aug. 26.
  • That intervention was Japan’s largest monthly currency operation on record, with part of the buying of yen carried out jointly with the United States.
  • The apparent sales likely included U.S. Treasurys, a sensitive point because Washington has worried that large Treasury selling could push up long-term yields.
