AI 中文总结

研究构建结算现代化指数,分析24个发达经济体改革事件,记录内部货币弹性S曲线及阶段。通过事件研究等表明结算现代化产生网络条件资产负债表效率,预测不同阶段效率提升,指出原子结算效率是双边对属性。

AI 中文摘要

我们构建了结算现代化指数,这是一个涵盖1993年至2024年期间24个发达经济体809个改革事件的面板数据集,分解为三个经济渠道和三个采用阶段。我们记录了内部货币弹性的S曲线,在结算现代化指数为0.27和0.93时有两个内部转折点,分隔了解放阶段、全球金融危机后的合规低谷和成熟基础设施复苏阶段。通过T2S事件研究和瑞士2021年后SDX部署的样本外合成控制无效,我们表明结算现代化通过逐年的EMIR分解产生网络条件资产负债表效率。应用于国际清算银行的三层连通性分类法,该框架预测2027年至2032年欧洲央行的庞特斯倡议将使效率提高13.4%。英国和美国有条件加入阿皮亚可组合层(2028年)将上限提高到37.5%。原子结算的资产负债表效率是双边对的属性,而非节点的属性。

英文摘要

We construct the Settlement Modernisation Index, a panel dataset of 809 reform events across 24 advanced economies between 1993 and 2024, decomposed into three economic channels and three adoption phases. We document an S-curve in inside money elasticity with two interior turning points at SMI = 0.27 and 0.93, separating a liberation phase, a post-global-financial-crisis compliance valley, and a mature-infrastructure recovery phase. We show that settlement modernisation generates network-conditional balance sheet efficiencies through a T2S event-study with year-by-year EMIR decomposition (saturation beta = +0.557, p < 0.01) and an out-of-sample synthetic control null on Switzerland's post-2021 SDX deployment. Applied along the BIS three-layer connectivity taxonomy, the framework forecasts +13.4 percent efficiency recovery from the ECB's Pontes initiative over 2027-2032. Conditional UK and US accession to the Appia composability layer (2028) raises the ceiling to +37.5 percent. Balance-sheet efficiencies from atomic settlement are a property of the bilateral pair, not the node.
