Japan's Long-Term Bond Yields Surge as US Rates Rise

Japan's long-term bond market experienced significant gains on the afternoon of the 30th, driven by a rise in US interest rates. The benchmark 10-year JGB yield increased to 2.805%, marking a 0.060 percentage point gain from the previous day.

The move was attributed to the impact of higher US long-term interest rates in after-hours trading during the Japanese afternoon on the 30th, which exerted selling pressure in Japan's bond market.

In contrast, the Ministry of Finance's auction of two-year JGBs held the same day saw lukewarm demand, with a bid-to-cover ratio of 3.63 times falling below the 12-month average of 3.81 times.

Market participants described the outcome as 'handled without incident,' indicating solid underlying demand in the short- to medium-term zone despite rising interest rates.

The broader yen-denominated bond market continues to react sensitively to US interest rate trends, with speculation about an additional rate hike by the Bank of Japan still simmering.
