Developed bond markets fell globally before the Bank of Japan’s policy decision Tuesday amid speculation the monetary authority will adjust its approach to providing stimulus.
Treasuries sank, pushing 10-year yields to a six-week high, following losses in U.K. and German debt. Yields on benchmark Japanese government bonds due in 2028 rose to an almost 18-month high during Asian hours before the BOJ offered to buy an unlimited amount of securities for the third time in a week.
