April 16 (Reuters) - China's finance ministry will keep this year's ultra-long special treasury bond issuance to 20-, 30- and 50-year maturities, the same as last year, people with knowledge of the matter said on Thursday.
Market participants have been watching 30-year supply because it could steepen the yield curve as the Middle East conflict stokes inflation concerns and curbs demand for longer-dated paper.
The people also said a separate batch of special bonds aimed at boosting the core tier 1 capital
of large state-owned commercial banks will come in five- and seven-year tenors, unchanged from last year.
The sources declined to be identified because they were not authorised to speak to the media.
The finance ministry did not immediately respond to a request for comment.
Investors had broadly expected a smaller allocation of 30-year special treasury bonds and the addition of a 15-year tranche, a view that had driven yields on ultra-long tenors lower over the past week.
The yield spread between China's 30-year and 1-year bonds widened to 1.16 percentage points last week, the biggest gap since August 2023.
Reuters reported on Tuesday that the ministry would meet government bond underwriters on Thursday to discuss this year's ultra-long special bond plans.
China's 2026 budget report shows 1.3 trillion yuan ($190.70 billion) in ultra-long special treasury bonds will be issued this year.
Separately, China said in early March that it would inject 300 billion yuan into state-owned banks this year to guard against systemic risks, and boost financing for technology companies amid an intensifying U.S. rivalry, down from 500 billion yuan last year.
Reuters reported last month that China is also considering easing shareholding restrictions for some major investors in a move aimed at broadening capital-raising options for commercial banks reeling from an economic slowdown.
