Data showed that government bonds with a maturity of over 10 years rose by 1.1% and local government bonds rose by 0.93%, significantly higher than other interest rate bond types. The main reason was that ultra-long interest rate bonds had the advantage of duration leverage, and the decline in yields led to a more significant increase in prices [2][33]. - Among long-term representative bonds, the ultra-long credit bond 24 Chengtong Holdings MTN009B had the highest monthly increase of 3.63% [37]. 4. Subordinated Alpha Tracking - In June, commercial bank subordinated bonds had positive alpha. Data showed that commercial bank subordinated bonds had an average increase of 0.05%, higher than commercial bank ordinary bonds and subordinated bonds. The alpha of commercial bank subordinated bonds mainly came from the significant decline in the yields of 7-year and 10-year commercial bank second-tier capital bonds and perpetual bonds. Although the yields of 20-year and 30-year commercial bank ordinary bonds declined more significantly, due to the small scale of ultra-long commercial bank bonds, the decline in yields had little impact on the overall price movement [2][39]. 5.
