The liabilities are the same currency and the same amount in 2023 and 2033. They’re solvent.

The asterisk is that the liabilities are generating interest, but this is fine because (one very safely assumes) that’s covered by the interest on the long-duration assets SVB bought.

Interest rates have risen since those long-duration assets were purchased.

Depositors now expect higher interest rates which cannot be covered by those assets. They will withdraw their deposits and move them to a bank that can offer higher interest rates.

right, which is why this is a liquidity problem and not a solvency one. The assets cover the liabilities--you just have to wait ten years or whatever.

No their bounds are worth fundamentally less than they paid for them.

There is a continuum in how quickly you need to sell and the price you willmget for something.

No.

Those are short term liabilities. The ability of depositors to withdraw their funds is part of the liability.

If the bank wanted to raise long term deposits it would have had to pay much higher interest rates.

Once they withdraw the bank can not raise additional funds because all other depositors have better interest rates in other banks.

No amount of time will cure this situation, the values of those bonds will not recover. This is not some temporary panic.

The only way for the situation to improve is if interest rates go down in the short term. Unless that happens, the bank remain insolvent.
