Why It Matters
Japanese government bond yields have been rising amid global pressure from increasing U.S. Treasury yields, with prior increases already reaching three-decade highs earlier this month following comments from U.S. Treasury Secretary Scott Bessent about expected action from Tokyo and the Bank of Japan to support the yen.
Japanese 10-year government bond yield rose to a 30-year high on Thursday, following a surge in U.S. Treasury yields, while concerns about inflationary pressures were exacerbated by a weaker yen.
The benchmark 10-year JGB yield rose 8 basis points to 3.055%, the highest since August 1996. The 30-year yield rose nearly 7 bps to 4.134%. The 5-year yield rose to a record high of 2.345%, up 7 bps.
