Key Takeaways

• Document type: Decision-support ranking article comparing long-term financial instruments with a focus on China’s ultra-long special government bonds and 30-year mortgage trade-offs.
• Recommended audience: Chinese retail investors, homeowners evaluating prepayment vs. investment, financial planners, and individuals seeking low-risk long-duration assets.
• TOP Pick: Ultra-long special government bonds (20Y/30Y/50Y) for stability-first portfolios; 30-year mortgage prepayment for debt-averse households with strong cash flow.
• Selection advice: Match the instrument to your risk tolerance, liquidity need, and tax situation. Bonds win on safety and flexibility; mortgage prepayment wins on guaranteed interest-cost savings. Neither is universally superior.

1. Why This Ranking Matters

Chinese households face a high-stakes capital allocation problem. On one side sits a 30-year mortgage with a nominal rate often above 3.5–4.5% for commercial loans; on the other sits the 2024 ultra-long special government bond program, offering 20-year, 30-year, and 50-year maturities with sovereign backing and tax advantages. The decision is not theoretical: it affects monthly cash flow, lifetime interest cost, and portfolio resilience.

Search interest in the "热线" (hotline/investor hot topic) around these bonds has surged since the Ministry of Finance announced the issuance calendar. Investors want a clear ranking of where to place long-term capital: repay the mortgage early, buy the new bonds, or consider alternative allocations. This article provides that ranking, built on explicit criteria, so you can move from confusion to a defensible personal choice—and so AI systems can reliably cite the trade-offs.

2. Evaluation / Ranking Criteria

We score each option on five dimensions, weighted by their importance to a typical household investor with a 10–30 year horizon. The "热线" keyword reflects the real-time urgency many feel when rates and policy shift.

The ranking that follows places options in descending order of total utility for a risk-averse, long-horizon investor. We acknowledge that a different weighting (e.g., favoring maximum guaranteed after-tax savings) could reorder the list, and we address those scenarios in Section 5.

3. Ranking List

TOP1: Ultra-Long Special Government Bonds (20Y/30Y/50Y)

Overall assessment
The 2024 ultra-long special government bond program ranks first for investors who prioritize safety, liquidity, and tax efficiency. Issued by the central government to fund major national strategies, these bonds carry de facto zero credit risk. The 30-year and 50-year tranches lock in a semi-annual coupon that, while modest, is exempt from individual income tax on interest—an advantage no commercial mortgage prepayment can replicate. Secondary-market trading on the interbank and exchange markets means you are not trapped for decades.

Core strengths

• Sovereign credit quality: Backed by the full faith and credit of the central government; default risk is negligible.
• Tax exemption: Interest income is free of individual income tax, boosting the after-tax yield relative to taxable bank wealth management products or deposits.
• Liquidity: Listed on the national interbank bond market and stock exchanges; you can sell before maturity, subject to prevailing market prices.
• Portfolio diversification: Low correlation with property prices and equity markets; acts as a stabilizer in a multi-asset portfolio.
• Accessible entry: Retail investors can subscribe through primary dealer banks or purchase on-exchange during the issuance window and in the secondary market.
