信达证券指出，过去央行在国庆、春节等长假前开展14天逆回购已是常态。考虑当前3M买断式回购若 按市场利率定价，或不超过1.55%，而过去14天与7天逆回购利差达15BP，若按照以往模式定价利率也 将达到1.55%，这就显得过高。因此央行将14天逆回购操作调整为固定数量、利率招标、多重价位中标 可能也会在实质上达到降息的效果。作为季末流动性的重要补充，央行调整14天逆回购展示了呵护跨季 的意图，这也有利于跨季资金价格回落。 招联首席研究员董希淼表示，本次改为多重价位中标后，14天期逆回购不再有统一的中标利率，可充分 发挥机构市场化自主定价能力，更好反映机构差异化的资金需求，公开市场7天期逆回购操作利率的政 策利率属性也更为清晰。同时，对银行业机构而言，银行等一级交易商需要提升自身的市场化定价能力 和资金管理水平，以适应新的招标机制。 财通证券首席经济学家孙彬彬分析称，14天逆回购招标方式的转变，体现的是央行中性偏呵护的态度， 未来短期资金价格锁定、但数量给够，中长期资金数量锁定、价格可以适度下行，一方面短期平抑波 动，另一方面中长期流动性不满不溢，但呵护银行负债，因此对债市偏利好。本周央行有极大概率重启 14天 ...
