First post-crisis stress tests, the SCAP (2009)
In the depths of the financial crisis, the Fed ran its first big stress test on 19 banks. Regulators found 10 needed to raise about $75 billion in new capital. The exercise, called SCAP, helped calm markets by showing which banks were sound.
Banks raised the capital, and confidence in the system began to return.
The test became an annual fixture and the model for how regulators police bank capital.
It explains why the test exists and why its results move markets. The 2026 fight is over how that now-permanent test is run.
