Credit Suisse is not included because it is a Swiss bank, not an FDIC insured US bank.
Lehman Brothers is also not included because, even though it was a US bank, it was an investment bank with no FDIC insured deposits. It was around the size of all of this year's failures, combined.
As you note, bank bailouts that were not FDIC bankruptcies are also not included.
I think GP knows this, but I also think you know that the graph is trying to paint a particular picture, and that picture is misleading because a lot of information is missing. We are not in the midst of a financial crisis that approaches 2008, and the graph is trying to make us think something different.
Not in an ‘08 sized crisis - yet. Wait until commercial property debt finally ‘looks down’. It’s been running off the cliff for a long time already, and is in exactly the same boat as the securities that took out SVB, etc.
I think someone found an interesting dataset, tried to visualize it, and thought it looked interesting. I doubt that there was any motive to the dataset other than, "Here's what I get from the FDIC, what does it look like?" Then shared code and source so that anyone else could reproduce it.
If you can find another data source that gives a fuller picture, you should. But compiling these data sources takes work. And the ones you get are all going to be a particular slice that represents some things but not others.
