The stress tests would not have identified this weakness...
"But even if midsize banks had been subjected to the same scrutiny as large banks, it isn’t clear that stress testing them would have led to changes that would have prevented failure. Why? Because the tests asked the wrong questions.
They failed to encompass the scenarios that ultimately led to SVB’s demise—large and rapid increases in interest rates.
In its February 2022 Stress Test Scenarios, the Fed’s “severely adverse scenario” asked banks to assess their riskiness over a three-year horizon in a hypothetical world in which the three-month Treasury rate stays near zero while the 10-year Treasury yield declines to 0.75% during the first quarter of 2022 and doesn’t change in the subsequent two quarters. Even in December 2021, however, the Federal Open Market Committee’s Summary of Economic Projections was showing the Fed likely targeting interest rates double those of 2022 in 2023, far higher than what it used for bank stress tests."
The Federal Reserve fails to account for interest-rate risk.
