Core Viewpoint - The recent surge in 30-year Japanese government bond yields to historical highs has raised concerns about the global bond market, indicating potential structural issues within the market [1][2][3]. Group 1: Japanese Bond Market Dynamics - The rise in 30-year Japanese bond yields began in mid-April and has led to fears of a "value trap," where bonds appear cheap but may continue to decline in value due to structural supply-demand imbalances [2][3][6]. - Since early April, the 30-year Japanese bond yield has increased by 85 basis points, while the 30-year U.S. bond yield rose by 60 basis points during the same period [3]. - For dollar investors, the 30-year Japanese bond yield, after currency hedging, stands at 7.03%, significantly higher than the 4.96% yield of the 30-year U.S. bond [4]. Group 2: Global Bond Market Implications - The issues in the Japanese bond market may serve as a warning signal for the global bond market, reflecting three major trends affecting bond markets worldwide: persistent inflation pressures, declining demand from asset-liability management (ALM) investors, and high government financing needs [8]. - Japan's core inflation rate has exceeded the Bank of Japan's 2% target for two consecutive years, contributing to rising equilibrium yields [8]. - The demand for long-term bonds is decreasing as market interest rates rise, with domestic holdings of long-term bonds stabilizing [8]. Group 3: Potential Responses from the Bank of Japan - The Bank of Japan's future policy direction is a focal point for market observers, with potential measures including reducing the maturity of issued debt, fiscal constraints, adjusting the quantitative tightening path, and possibly restarting a rate hike cycle [13][14][18]. - The expectation is that the Bank of Japan will maintain a steady pace of reducing its bond purchases, with a target of 2 trillion yen per month starting in April 2026 [17].
