机构：30年期日债收益率可能回落至3%以下

Core Viewpoint - The 30-year Japanese government bond yield is expected to fall below 3% next year due to its current yield premium over the 10-year yield being significantly higher than similar overseas bonds [1] Group 1: Investment Demand - Large institutional investors, such as Japanese insurance companies and banks, show limited interest in the 30-year Japanese government bonds [1] - Global investors may find these ultra-long bonds attractive due to the substantial premium over the 10-year yield [1] Group 2: Global Investment Strategy - U.S. investors, including Pimco, may prefer investing in Japanese government bonds to extend duration rather than extending the interest rate curve in other markets [1]
