现券交易中，"其他"债券怎么对应？ 证券研究报告 信用策略随笔 本篇聚焦：从有限可得的数据维度中，如何相对准确和细化地跟踪二 永债的机构交易行为？ 一、"其他"债券主要指哪些？ "其他"债券主要包括商业银行普通债、二级资本债、PPN 等除了单 独列示的其他银行间债券类型。 对比现券交易数据和成交数据，大致对应商金债、二永债、PPN这三 类。 固定收益 | 固定收益专题 二、券种和期限分类上，还能进一步细拆吗？ 现券交易数据披露的期限分类多根据到期期限，基于个券成交明细， 按到期期限分类与之对应，大致有如下几处对应： 1、5 年内"其他"债券多为商金债和 PPN 5 年内的"其他"债券中约 85%以上为商金债和 PPN，其中商金债约 占 50%，PPN 约占 35%；此外还有少量的 TLAC 债、二永债等债券。 由于商金债基本不含权，对应到期期限即为实际剩余期限；部分 PPN 含权，到期期限分布和行权期限分布不完全一致，但均主要落在 5 年以内。 故而若再进一步细分期限，或有较大偏差。但对基本不参与私募债交 易的机构而言，5 年内及细分期限的现券交易基本可看作为其对商金债买 入或卖出。 2、5 年以上"其他"债 ...
