证券研究报告 | 2025年08月25日 超长债周报 股债跷跷板 核心观点 固定收益周报 超长债复盘：上周债市继续大跌。上周税期资金面收紧，公布 8 月 MLF 超额续作 3000 亿，A 股放量大涨，上证指数创 10 年新高，股债跷跷板 效应明显，超长债继续暴跌。成交方面，上周超长债交投活跃度小幅下 降，交投相当活跃。利差方面，上周超长债期限利差走阔，品种利差走 阔。 超长债投资展望： 30 年国债：截至 8 月 22 日，30 年国债和 10 年国债利差为 31BP，处于 历史偏低水平。从国内经济数据来看，7 月经济依然面临下行压力。我 们测算的 7 月国内 GDP 同比增速约 4.3%，较今年上半年的增速大幅下滑。 通胀方面，7 月 CPI 为 0.0%，PPI-3.6%，通缩风险依存。我们认为，短 期债市会不断面临预期和现实的博弈，10 年期国债在【1.65%，1.8%】 区间震荡。一方面，现实基本面依然偏弱，对债市形成支撑；另一方面， "反内卷"的确是当前政策的重要抓手，投资者通缩担忧有所消散，长 期宏观叙事出现变化，预期和情绪对债市产生压制。当前 30 年国债期 限利差依然偏低，期限利差保护度有限 ...

华泰证券研报称，当前债市票息保护弱、重博弈、情绪驱动强，投资体验"事倍功半"。短期债市仍处逆 风，但利率大概率"上有顶"。短期维持十年国债老券上限在1.8%附近（配置盘开始关注），极限位置是 1.9%（交易盘介入），潜在超调风险仍来自于机构行为。时间上，十月份之后（供给淡季+情绪拐点 +消费等高基数）再寻找"反攻"机会。资金面持续收紧风险不大，继续推荐曲线陡峭化交易。品种上， 30年国债、二永债等品种容易成为情绪放大器，建议暂时规避。5-7年及以下利率债品种兼具防守特 性，杠杆套息浅尝辄止。信用债以中短端为主，3-5年普通信用债经过本轮下跌后初具性价比。转债保 持权益β暴露。 ...

Summary of Conference Call Records Industry Overview - The records primarily discuss the bond market, particularly focusing on local government bonds and the impact of VAT adjustments on pricing and investment strategies [1][2][4]. Key Points and Arguments 1. **Bond Market Dynamics** - Local government bond yields are converging, with a notable focus on older bonds that have higher coupons and better liquidity. New code bonds need to be reassessed for relative and absolute returns [1][3]. 2. **Impact of VAT on Bond Pricing** - Following the reintroduction of VAT, the pricing of bonds has shown a convergence in volatility. For instance, the yield range for 10-year government bonds has decreased from 1.70-1.75% to 1.68-1.72%, indicating a market in a waiting phase [2][7]. 3. **New Code Bonds Performance** - New code local government bonds are actively issued, with yields averaging 5 basis points higher than old code bonds. The pricing reflects a 3% VAT, primarily driven by proprietary trading desks, indicating a balance in tax burden sharing [4][6]. 4. **Liquidity and Spread Changes** - Both new and old local government bonds exhibit high liquidity, leading to a narrowing of spreads. The 30-year and 10-year government bonds are highlighted as having significant investment value due to their high spread positions [5][6]. 5. **Real Estate Market Insights** - The recent easing of real estate purchase restrictions in Beijing does not signal a new relaxation cycle. Existing policies are near their limits, and significant recovery in the real estate market is unlikely until 2026, requiring additional policy measures [6][7]. 6. **Inflation and Economic Stimulus** - Inflation recovery is expected to take time, with commodity prices reflecting more elasticity in futures rather than spot markets. Structural economic stimulus measures are deemed necessary for long-term stability [1][6]. 7. **Central Bank's Cautious Approach** - The central bank has shown caution in liquidity provision, with recent operations indicating a careful approach to market dynamics. The probability of funding rates dropping below 1.2% is considered low, reflecting a stable yet cautious monetary policy stance [2][7]. Other Important Insights - The market's risk appetite is diminishing, with a shift in focus from risk assets to bond market dynamics. The correlation between stock markets and bond markets has weakened, indicating a more cautious investment environment [2][3]. - The competition for older bonds is categorized into three types based on their issuance time, coupon rates, and liquidity, highlighting the strategic adjustments needed in investment approaches [3][4].
