According to Jin10, data released on April 2 indicates that Japan's 10-year government bond auction experienced its weakest demand since May of last year. This decline is attributed to rising oil prices, which have heightened inflation concerns and dampened investor interest. The bid-to-cover ratio fell to 2.57 from 3.3 last month, falling short of expectations and below the 12-month average of 3.28. As a result, prices for existing 10-year and 30-year government bonds have decreased. On Thursday, global bond yields generally rose. This followed U.S. President Donald Trump's statement that the United States would launch an extremely severe strike on Iran within the next two to three weeks, diminishing hopes for a swift resolution to the conflict. The yield on Japan's 10-year government bonds rose to 2.35%, slightly below last month's peak of 2.39%. Following Trump's remarks, the yen weakened to 159.48. Investors are increasingly speculating that the Bank of Japan may need to tighten policy to address the yen's depreciation. The yen had briefly fallen below the 160 mark late last week and earlier this week. Overnight index swaps indicate that traders expect a more than 70% chance of a rate hike by the Bank of Japan in April, with a full pricing in of a 25 basis point increase by July.
