Facebook wants to "deepen user engagement" with Messenger, and to that end, it's been pitching America's giant banks on joint enterprises where Facebook will get to see all your financial info (especially info on where you're shopping and what you're buying) to help it suck you into using Messenger for longer.
In return, Facebook offered to let the banks do business through its platform, allowing Facebook users to transact business and manage their finance through Facebook Messenger.
However, it promised the banks that the financial data they turned over wouldn't be shared with third parties.
The news that Facebook might be able to access all this financial data resulted in a massive share-price surge, with shares up 3.5%, recovering much of the ground lost during Facebook's share-price bloodbath last month.
