长江固收 10 年期国债能破 1.6％吗？20260629 摘要 短期内，国债收益率在 1.6%附近面临较强阻力，一季度债市曾下探至 1.57%左右，这些位置构成阻力位。当前收益率在 1.65%-1.7%之间调 整空间有限，接近 1.65%时可逢低配置，但接近 1.6%时需关注回调风 险。 市场对国债买卖重启的预期需要推迟。央行重启国债买卖需满足国债供 给和收益率两个条件。短期内国债供给无明显增加，若财政不进行大规 模新增特别国债或增发，年内重启概率较低。 央行更能接受国债收益率上行，大幅度下行存在系统性风险。为避免直 接跌破关键点位如 1.6%，央行可能会等待市场调整到更高水平再考虑 重启。稳定汇率同样重要，更倾向于贬值而非升值。 央行购买国债会增加流动性，国债到期财政兑付给央行不涉及银行，不 会直接影响基础货币和流动性。财政兑付时，央行资产端和负债端同步 减记，体现缩表，但对流动性的影响是间接的。 今年中国央行降息空间可能有限，或有一次降息机会，幅度约为 10 个 基点，时间在三季度末或四季度初，需根据外部形势变化决定。下半年 的降息可能更多服务于稳增长，应对经济压力。 Q&A 当前市场情绪和利率债表现如 ...
