COMMENT: Nice summary.
Here's the bottom line: "U.S. banks had $620 billion in unrealized losses on securities at the end of 2022, according to the FDIC. A March study from professors at New York University and Wharton estimated that their unrealized losses are closer to $1.7 trillion when accounting for all loans and securities."
If the FED hikes rates, the economy slows, etc, theses losses get even worse. The system is insolvent at deep level.
