BBH has expanded its account opening API connectivity to custodians, with SEB being the first to implement the solution. This builds on last year’s API integrations with major European fund distribution platforms, Allfunds, Clearstream and Euroclear. BBH’s account opening API supports straight-through exchange of account opening requests and confirmations between distributors, banks, platforms and custodians, helping shift onboarding from days to hours – and in some workflows, minutes.
