Concerns about Japan’s upcoming economic stimulus package have led to a decline in Japanese long-term government bonds. Odaily reports that yields on 20-year, 30-year, and 40-year bonds all hit their highest levels since 1999, signaling investors’ unease over fiscal policy decisions. The rise in bond yields comes as trading activities are influenced by the details of Prime Minister Sanae Takaichi’s economic plan. While GDP data released on Monday supported Prime Minister Takaichi’s push for a large-scale stimulus plan, it also contradicts expectations of interest rate hikes from the Bank of Japan in the coming months. Experts note that uncertainty surrounding potential increased debt issuance is causing selling pressure on long-term bonds.
