Japan's long-term interest rates have surged to their highest level in 30 years, driven by rising oil prices amid instability in the Middle East and concerns over additional government spending.
According to the Nikkei newspaper on May 18, the yield on newly issued 10-year government bonds briefly reached 2.8%, the highest level since October 1996. An increase in bond yields typically indicates a decline in bond prices.
The 10-year bond yield rose by 0.1 percentage points from the end of the previous week. The Nikkei reported that ongoing inflationary pressures from rising oil prices and worries about increased fiscal spending have led to a continued sell-off in bonds.
As turmoil in the Middle East persists, oil prices remain elevated, heightening inflation concerns both domestically and internationally. This has led to a noticeable trend of investors shying away from purchasing bonds. Rising inflation fears increase the likelihood of higher interest rates, which negatively impacts bond prices that move inversely to interest rates.
The Nikkei noted that significant increases in long-term interest rates in European and U.S. markets at the end of the previous week influenced the Tokyo market early in the week. U.S. long-term interest rates rose to nearly 4.5%, marking their highest level in about a year, which exerted upward pressure on Japanese rates.
Domestically, there are growing expectations that the government will prepare a supplementary budget for the fiscal year 2026, raising concerns about expansive fiscal policy. The anticipation of increased government spending could lead to a rise in bond issuance and fears of fiscal deterioration, contributing to the bond sell-off.
Notably, the sell-off has been particularly pronounced in ultra-long-term bonds, which are more sensitive to fiscal concerns. The yield on 30-year bonds also briefly reached 4.17%, setting a new record high.
