三菱日联金融集团(MUFG)正推进一项日本国债链上结算测试,计划借助区块链把原本通常需要 1 至 3 天完成的结算流程,压缩至接近实时处理。该项目将以 Canton 网络开展概念验证,重点放在日本国债回购交易的结算效率上。

测试聚焦日本国债回购

日本国债因信用水平高、流动性强,长期被日本及海外市场参与者用作回购交易抵押品。回购交易本质上是以证券作为抵押进行短期融资和融券安排,因此结算速度会直接影响资金周转与抵押品使用效率。

MUFG表示,这次测试希望通过 24 小时、7 天不间断的链上结算,改善回购交易的运营效率和资本使用效率。若测试顺利,金融机构可更快完成抵押品转移与资金交收,减少传统流程中的等待时间。

传统结算通常需 1 至 3 天

按照现有模式,日本国债交易结算通常需要 1 至 3 天。MUFG认为,若改用链上方式处理,可缩短交收周期,并提升盘中流动性调度能力。

这一方向并非日本独有。MUFG提到,欧美金融机构近年也在推进类似试点,目标同样是把高质量抵押品交易搬到可实时处理的区块链网络上。

  • 测试网络:Canton
  • 应用场景:日本国债链上交易与回购结算
  • 目标效果:实时、全天候交收

海外已有类似先例

在美国,基于区块链的国债日内回购安排已运行数年。摩根大通的 Kinexys 网络自 2020 年上线后,已被用于美国国债相关的链上回购场景。MUFG此次推进概念验证,也被视为日本大型银行跟进这一趋势的最新动作。

MUFG还表示,随着日本国债作为高信用、强流动性资产的使用范围持续扩大,推动其上链的市场需求正在增加。这意味着区块链在传统固定收益市场中的应用,正从概念探索逐步转向更具体的交易与结算场景。

同步推进稳定币合作

这项测试也是 MUFG 更广泛区块链布局的一部分。该行近期已与三井住友金融集团(SMBC)和瑞穗金融集团(Mizuho)展开合作,研究在 2027 年 3 月前推动一款联合发行稳定币上市。

如果相关项目继续推进,日本大型银行在国债结算、抵押品管理和稳定币支付之间,可能形成更紧密的链上金融基础设施连接。
