SVB got blown up on a trade that is kind of at the core of what banks do (this is also why every bank is hurting). To even exist the bank has to be stuffed full of people very knowledgeable about rates risk at all levels of management. There should have been no shortage of people at any level, including executive, that understood the risks.
It wasn’t even like this was some weird bespoke product or something, they got blown up by plain treasuries afaiu. This is the sort of thing that’s “introduction to rates 101” material. They didn’t need a CRO to tell them this.
Because HoldForMaturity assets can't be hedged? Or it cuts into profit and affects your stock and management bonuses which they weren't used to giving up, and your share losses due to the hedge imperil your company but just in a different way?
As for the hedge, it’s probably a greed/returns question. If you buy then 10 year and sell everything between say 2 to 10 years as a curve hedge, you’ve basically bought the two year with extra steps. There’s no free lunch where you get returns of ten year without the risk on ten year.
You could imagine some imperfect hedge might be better but sort of same problem.
They had no interest rate risk hedges the entire time.
Edit: Downvotes with no replies. I hate it when that happens.
