Same with their mortgage-backed securities.
Ish. On a mark-to-market basis they had insufficient reserves. That's closer to insolvency than illiquidity. The mismanaged duration is closer to illiquidity. But not of the sort a lender of last resort could save them from.
Hold-to-maturity assets are not required to mark to market, for example.
And it's not based on what they paid for it from what I gather, it's based on what the total payout will be when it matures.
Imagine a bank takes demand deposits and pays a variable rate of the base rate minus 1%. The bank then makes fixed rate, 30 year mortgage loans that it intends to service itself at the base rate plus 2% (portfolio loans).
Interest rates then go up.
Bang: that bank just became insolvent. Is this actually the model of the world you want?
I'm not sure what the problem is, this model to me actually seems reasonable. The alternative is to claim that "We are solvent as long as our clients keep deposits in our bank and are happy with an interest rate lower than our competitors for 30 years".
In fact the scenario you're describing is basically what happened to SVB except the interest rates increased more.
I guess the main issue is that generally banks do take a risk by borrowing short and lending long, and hope that things work out in the end.
This is irrelevant in a scenario where every client wants to withdraw their money, because the only way SVB can fulfill that is by selling their HTM assets at the current market price, which will be at a heft discount compared to where they bought them.
When yields rise, prices fall. Remember that.
Now let's say you need to access that emergency fund, and the amount you need is 90% of it. However, what you've found is that treasury prices have fallen so far, your investment is now only worth 50% of what it was before unless you hold it for another 5 years. If you don't sell now, you will be homeless. If you do sell now, you buy a bit of time and can possibly get a loan, and barring that, you will be homeless.
That is what happened to SVB.
If you need a closer date (because you need to fulfill customer cash flow requests), then solvent plus illiquid can become insolvent quickly.
Right now SVB, if fully liquidated, cannot repay all of the deposits.
If I have assets worth $110 today but they are locked up, and I have to pay back what I owe today, then I’m facing a liquidity crisis.
If I have assets worth $90 today, but $110 in a few years, and I have to pay back the money I owe in a few years, then I’m solvent and everything is good.
If I have assets worth $90 today, but $110 in a few years, and I have to pay back what I owe today then I’m insolvent.
Per the FDIC
Still certainly very possible that the analysis is incorrect.
