Japan 10-year bond yield hits 3%, highest in 30 years

Japan's benchmark 10-year government bond yield climbed to 3.0% on Tuesday, marking the highest level since October 1996. The increase was influenced by concerns surrounding Japan's deteriorating fiscal health. This milestone occurred just a day after government departments submitted budgetary requests totaling a record 143 trillion yen ($890 billion) for the upcoming fiscal year.

Prime Minister Sanae Takaichi's strategy to boost government spending to stimulate the economy, despite Japan's significant debt burden, appears to be contributing to the rising bond yields. The upward trend in Japanese government bond yields follows market expectations that the Bank of Japan will increase interest rates during its September policy meeting.

Despite Japan's coordinated currency intervention with the United States, the yen has continued to weaken, exacerbating inflationary pressures in the resource-scarce country. The higher bond yields translate to increased debt-servicing costs for Japan, which already has the worst fiscal health among advanced economies, with outstanding debt twice the size of its economy.
