分析人士认为，展望2026年，在信用风险未明显抬升的背景下，信用利差预计维持较低水平，增量事件 带来的利差走阔将创造配置时点。 新华财经上海11月19日电 今年以来，债市信用利差总体处于低位，波段震荡特征明显。 信用利差低位震荡 中央国债登记结算有限责任公司提供的数据显示，截至11月18日收盘，银行间信用债市场收益率小幅波 动。举例来看，中债中短期票据收益率曲线（AAA）3M期限上探1BP至1.61%，3年期收益率下行1BP 至1.86%，5年期收益率稳定在1.99%附近；中债中短期票据收益率曲线（A）1年期回落1BP至6.90%。 值得一提的是，"信用债通常很难脱离利率债形成独立走势，因此，信用债的择时与波段操作本质上仍 是延续利率择时的框架。"曾羽表示，"在当前的市场环境中，基于增量事件的择时应为操作核心。从大 趋势上看，货币政策保持适度宽松，社会融资规模增长依赖政府债供给，信用市场资金供给多而债券供 给少的核心逻辑并未转变。也就是说，市场持续缓慢走强的格局在未来一段时间内难以转变。此间，增 量突发事件带来的信心变化和短期回撤将拉扯出估值空间，构成信用债配置和波段交易的时机窗口。 即，各机构需关注增量事件 ...
