The account I've seen people pointing to that paid that was definitely a money market account. Also, there's an interesting chart doing the rounds on Twitter showing that during the time period they dug themselves into this mess most of the deposits held there weren't being paid interest at all: https://twitter.com/mattyglesias/status/1635431225945890816 Once again, the problem isn't that they were paying unreasonably high interest by taking risks and the customers were benefitting from this - this isn't Icesave in 2008 - it's that due to global interest rate rises people and businesses were no longer as willing to hold large amounts of money there at zero interest and they couldn't afford to pay market interest rates to everyone to keep deposits at the bank.
