First of all, I've seen no evidence that 720 banking institutions have failed, just the ravings of some fanatic. What's amazing to me is how someone can take people like this seriously.
If you are referring to my post your response demonstrates you didn't understand what was said.
Bonds held by a bank are an asset. Since interest rates have gone up the sale value of the bond has gone down. That is called a "unrealized loss". They do not have to declare that loss, they can hold the bond to maturity and never declare a loss.
The fact that 50% of their assets have unrealized losses means that 50% of their assets have been negatively impacted by the rise in interest rates.
These are facts that everyone who understands the banking industry can see.
The reason that major banks are failing and we have had several very major bank failures in the last few weeks is because of this same fact. The banks hold bonds that pay next to nothing in interest rates, but you can move your money to a money market which will pay much more than the bank will. However, if you move the money the bank will have to sell those assets, hence the "unrealized losses" become realized. With every bond they sell their precarious financial situation becomes more precarious because they are declaring losses.
This however, is only half the catastrophe that the banks find themselves in. The other half is the fact that commercial real estate has a very high vacancy rate. Companies are learning they don't need as much office space and they are going to walk away from the leases and leave the banks holding the bag. This is a major problem to 2,000 regional banks.
When you see layoffs of thousands of people, if those are white collar jobs you aren't just putting people out of work you are probably also going to leave commercial real estate for the bank to deal with.
