I noticed that my banks (at least in France) start to offer the ability to consolidate accounts from other banks (in order to have a unified view of all belongings).
This is not done though a public, generally available API, but via a backend mechanism. This means that, as opposed to scrapping, they actually offer (or cross-offer) this functionality between them.
Why do they do that?
Looking at the fierce competition in that area, I would have expected that they would not be willing to share their data with other banks, to force customers to connect to their portal and, possibly, buy some extra services. If I can view another account (possibly less important, or with a worse interface) though a consolidated dashboard, I have no incentive to connect there.
