Abstract

Bank adoption of external application programming interfaces (APIs) enables bank customers to share their data more efficiently and securely with other third-party financial institutions and FinTechs, thus enabling open banking and bank data portability. Analyzing determinants of API adoption by U.S. banks from 2007 to 2022, we show that banks that adopt APIs tend to be larger and face lower competitive pressures. The announcement of President Biden’s executive order in July 2021 encouraged increased bank data portability and led to an acceleration in bank API adoption. Banks that adopt APIs experience an increase in Return on Assets (ROA) and Tobin’s Q and a decrease in loan loss provisions, particularly after President Biden’s executive order. We find that APIs’ ability to facilitate data access and sharing improves bank information flows and supports banks’ loan and deposit services which form the foundation of notable improvements in bank performance. Overall, our results on the determinants and implications of API adoption have important policy implications for the discussion on open banking regulation and bank data portability.

美国银行的开放数据和API采用

银行采用外部应用程序编程接口（api）使银行客户能够更高效、更安全地与其他第三方金融机构和金融科技公司共享数据，从而实现开放银行业务和银行数据可移植性。通过分析2007年至2022年美国银行采用API的决定因素，我们发现采用API的银行往往规模更大，面临的竞争压力更小。拜登总统于2021年7月宣布的行政命令鼓励了银行数据可移植性的提高，并加速了银行API的采用。采用api的银行在资产回报率（ROA）和托宾Q （Tobin’s Q）方面有所增加，贷款损失准备金有所减少，尤其是在拜登总统发布行政命令之后。我们发现api促进数据访问和共享的能力改善了银行信息流，并支持银行的贷款和存款服务，这是银行业绩显著改善的基础。总的来说，我们关于API采用的决定因素和影响的研究结果对开放式银行监管和银行数据可移植性的讨论具有重要的政策意义。
