The long-term Japanese government bond slump is intensifying, and the market is increasingly concerned that a large-scale economic stimulus package will impact public finances.

According to the Wise News Finance APP, long-term Japanese government bonds fell further on Tuesday, with investors increasingly concerned that Prime Minister Chikara Koshi Naona's large-scale economic stimulus plan will harm Japan's public finances. Data shows that the yield on Japan's 40-year government bonds jumped 8 basis points to 3.68%, the highest level since 2007; the yields on 20-year and 30-year government bonds each rose by at least 4 basis points, with the 30-year government bond yield just a few basis points away from its historical high.
