Restricted CGIDE – API standards for data-sharing – October 2022 39 Annex A: Survey on API standards for data-sharing As an initial step, the CGIDE TTF APIs for data-sharing conducted a survey to collect relevant information from the eight participating central banks in this group (Argentina, Brazil, Canada, Chile, Colombia, Mexico, Peru and the United States). The objective was to collect information on considerations around the implementation of APIs for the secure and effective sharing of customers’ data between financial institutions, fintech firms and certified third parties. The design elements covered in this survey include the types of entity that would be part of the data-sharing process, design considerations for API standards, the type of shared information and its use, and the main drivers for implementing data-sharing. The information served as a basis for discussion on the technical requirements for the implementation of data-sharing. The data from the survey show that central banks in the group are interested in open finance, and specifically in data-sharing. Most of the participants have already implemented data-sharing as part of their open finance initiatives or plan to implement it within the next three years (Graph 17, left-hand panel). Most participants consider that increasing efficiency and promoting competition are the main drivers for adopting and implementing data-sharing in their respective jurisdictions (Graph 17, right-hand panel). Other drivers are the need to regulate access to data, improve financial inclusion, promote innovation and improve data security and privacy, among others. As data-sharing can adopt a model depending on the needs and desired characteristics of each country, the results do not show a particular interest in any specific model. Half of the participants indicated that they would be interested in adopting a centralised model, while three other participants would consider a decentralised model. Another important consideration is the need to restrict the use of the information obtained within an open finance and data-sharing ecosystem. Having an API standard is a major step in implementing data-sharing. Only one participant already has a standard in place in the financial system for this purpose, while six participants plan to introduce one in the next three years. All participants agree that financial institutions should participate in the ecosystem. Most of them consider that banks should participate, while others indicate that PSPs and e-money issuers, among other financial institutions, should also participate. Six participants also state that fintechs should be part of the Interests and motivations for data-sharing Graph 17 Is your country considering data-sharing as part of its open finance initiatives? What would be the key drivers for data-sharing adoption/implementation? Per cent No. participants Source: Central bank survey |
