HSBC USA

HSBC USA is the United States arm of HSBC Holdings plc, operating principally through HSBC Bank USA, N.A., a nationally chartered bank supervised by the Office of the Comptroller of the Currency (OCC). After exiting mass-market domestic retail banking in 2022 — selling its East Coast branches and national online deposit business to Citizens and its West Coast branches to Cathay Bank — HSBC refocused its US operations on global wholesale, commercial and corporate banking, global banking and markets, and wealth management for internationally connected clients. On the open-finance front, HSBC USA does not publish a US-specific first-party developer program; public API access is provided through HSBC's group-wide corporate and institutional Developer Portal (developer.hsbc.com), whose transaction-banking API products serve US wholesale clients but require registration and login to reach the actual API reference and specifications. There is no publicly downloadable OpenAPI, and consumer-permissioned data access for remaining US accounts is mediated through third-party aggregators rather than a documented first-party consumer data-sharing API.

HSBC USA publishes 2 APIs on the APIs.io network. Tagged areas include Financial-Services, Banking, United States, Corporate Banking, and Transaction Banking.

HSBC USA’s developer surface includes engineering blog, signup flow, documentation, support, and 13 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Banking & Open Finance regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
