in a nutshell (I don’t have the time to write a treatise on this, every word I write is 20w i could have read instead): I’m pretty confident (status: ~ .6) that if SVB had 90bi in gov bonds HTM instead of MBS and the like, it wouldn’t have failed. You can say it would have had losses (especially in 2022), it would likely have been bought, but not failed.
I know of no bank that has suffered a run because they had too much gov long term bonds (from the corresponding government, and unless the gov defaulted, ofc) in the last century (if you have an example, please enlighten me); not only there’s a very liquid market for them, but, in the last century (perhaps since Badgehot) central banks will let banks convert them into money easily—because tax payers will suffer no losses. On the other hand, MBS (and other similar derivatives) may be linked to credit risks (even Agency MBS) and it’s quite unsure how your liquidity line will work, and the market is not so liquid; and that’s why they offer higher yields—which is why they dominated SVB’s HTM.
Thanks for the memory refreshing lecture on the crisis of 2008. But I still remember almost everything
