Equinix.com Confidential The emergence ofBanking as a Service Payments White Paper 4 In October 2020 in Australia, Westpac announced a partnership with Afterpay, one of the world’s leading Buy Now, Pay Later brands, to provide deposit accounts as part of its new Banking as a Service strategy, commencing in Q1 2021. The agreement makes Afterpay the first third-party fintech to be launched on Westpac’s cloud-native “10X” digital banking platform, which is provided by Future Technologies. The move is part of Westpac’s new digital strategy to engage and work with fintech partners through the 10X platform, a system that is operated separately from the main Westpac banking system. As part of the agreement, Afterpay’s 3.3 million Australian customers will be able to open transaction and savings accounts with Afterpay and undertake transactions without needing an external bank. Afterpay would then have access to all of the spending data from the deposit accounts, from which it plans “to assist them [their deposit account holders] in budgeting more effectively and avoiding debt traps” through the provision of budgeting and spending tools. The data could also potentially be used in the credit-decisioning process for future Afterpay credit/loan products. Although Afterpay does not hold a banking license in Australia, it is able to use Westpac’s own license as part of the BaaS arrangement. Therefore, Afterpay deposit account holders would be covered for up to AUD250,000 as part of the Australian Government’s deposit guarantee scheme.
