U.S. banks are sitting on $326.7B in unrealized losses

HUGE: U.S. banks are sitting on roughly $326.7 billion in unrealized losses on investment securities.
The total has increased for two consecutive quarters.
These losses do not automatically become realized, but they matter when banks need liquidity or are forced to sell longer-duration assets at depressed prices.
With yields still elevated, interest-rate risk remains a major balance-sheet issue across the banking system.
