> However, the "risky" investments that I have heard described thus far are mostly treasury securities You assume that all risk is default risk. The risk that SVB took wasn't that the US govt will default on its bonds. It was that the treasuries will lose their value in case of interest rate changes. SVB bought billions of dollars of US treasuries which lost their value in the last year due to rate hikes. This showed…
No, I understand the liquidity risk involved in having too much tied up in long term treasuries. But I am yet to see evidence that any bank could have withstood a run of that magnitude. Nor have I seen much evidence that most other banks have significantly less liquidity risk than svb did.
In traditional banking, rising interest rates are a good thing because it means that banks in turn get to underwrite loans at higher interest rates, which positively affects their bottom line. SVB's problems were twofold: A) they had a one-dimensional investment strategy that was adversely affected by rising rates, and B) outstanding loans made up a very small portion of their business relative to their size, which made it so that they weren't able to capture meaningful value from rising interest rates. The latter is actually pretty rare for a bank, which shows how uninterested they were in actually functioning like one.
