Because after COVID and the whole Ukrainian happening the world economy is in a bit of a disarray, so people except bad things to happen, therefore they are looking for the signs of those bad things finally starting to happen. Apparently this is what happened:
>the bank in question kept nearly all of its money in bonds
>bonds have a fixed interest rate*, a face value and a market value
>the face value and a market value are different, because bonds released at different times can have different interest rates, and you don't want to pay $100 for a bond with a face value of $100 and a 5% interest rate if you can instead pay for a bond that has a face value of $100 and an interest rate of 10%
>if a central bank raises the interest rate then bonds released after the raise have to have a higher interest rate
>this means that bonds released before the raise go down in market value simply because they are not as good an option
>in this case you can either keep your old bonds and accept that you get less money overall
>or sell them at a discount to someone who doesn't mind the lower interest rate, and use the proceedings to buy newer bonds
Now, the bank wanted to sell its older bonds and buy newer ones, but doing so would have lead to some temporary losses as they'd have to sell them at a discount. To make up for that loss they wanted to sell some of their shares, except that investors assumed they must be in trouble, and so they too started selling the shares, turning it into a self-fulfilling prophecy.
*The actual interest rate might be tied to something else, so it can fluctuate overall, but again, it is tied to something else, and it's not just up to the whims of whoever release the bonds to randomly set a new interest rate, so you can have some expectations about how much those kind of bonds might pay down the lane.
