Almost half of America’s 4,800 banks have already burned through their capital buffers and are running on negative equity. They may not have to mark all losses to market under US accounting rules but that does not make them solvent. Somebody will take those losses.

“It’s spooky. Thousands of banks are underwater,” said Professor Amit Seru, a banking expert at Stanford University. “Let’s not pretend that this is just about Silicon Valley Bank and First Republic. A lot of the US banking system is potentially insolvent.”

The full shock of monetary tightening by the Fed has yet to hit. A great edifice of debt faces a refinancing cliff-edge over the next six quarters. Only then will we learn whether the US financial system can safely deflate the excess leverage induced by extreme monetary stimulus during the pandemic.

A Hoover Institution report by Prof Seru and a group of banking experts calculates that more than 2,315 US banks are currently sitting on assets worth less than their liabilities. The market value of their loan portfolios is $2 trillion lower than the stated book value.

These lenders include big beasts. One of the 10 most vulnerable banks is a globally systemic entity with assets of over $1 trillion. Three others are large banks. “It is not just a problem for banks under $250bn that didn’t have to pass stress tests,” he said.
