Now imagine this: SVB have sold their bonds at huge discount. They’ve collapsed because the no one wanted long-term bonds with small interest in the current rates are high.

Now: FED is going to lower the rates so the bonds sold by SVB will increase the value. Someone has bought them at a huge discount and will sell with nice profit. Someone who doesn’t have to worry about “bank runs” (not a bank?), someone who will sell them going from the discount + will score the interest guaranteed by the government.
