It’s not a very simple question to answer sadly @ricochet . I’ve posted a similar answer below
Basically the regulations require banks to make ‘Payment Accounts’ available via Open Banking and there is not a very simple definition which defines if a certain type of savings account falls under this or not. So normally the bank’s own compliance teams make that determination.
This may not match what the bank would say - but generally speaking if you have a savings account which can only move money to/from a linked bank account… that will NOT be considered a Payment Account. That’s my summary of it.
Also to confirm - Marcus don’t support Open Banking right now as far as we are aware.
