Digital Currencies and Monetary Policy Transmission: Evidence from a Natural Experiment

Wang H., Zhang Y., Li M.Peking UniversityReview of Financial Studies(RFS)2025-11

Abstract

We exploit the staggered rollout of China's digital yuan (e-CNY) pilot program as a natural experiment to study how central bank digital currencies affect monetary policy transmission. Our findings reveal that e-CNY adoption accelerates the pass-through of policy rate changes to deposit and lending rates, particularly in regions with lower financial inclusion.

核心观点Key Findings

数字人民币(e-CNY)的采用显著加速了政策利率变动向存贷款利率的传导,尤其在金融包容性较低的地区效果更为明显,表明CBDC能有效改善货币政策传导机制。

研究方法Methodology

利用中国数字人民币试点的分阶段推出作为准自然实验,采用双重差分法(DID)分析CBDC对货币政策传导效率的因果效应,控制地区经济特征和金融发展水平。

主要结论Conclusions

央行数字货币通过降低支付摩擦和提高金融包容性,能够增强货币政策的有效性。这一发现对全球CBDC政策设计具有重要参考价值。
