Only indirectly. They released a statement after the FTX collapse saying effectively "don't worry, no problem here", which caused a bank run that they couldn't manage and forced the collapse.

They are related in that crypto (and ftx) and the massive explosion of start-ups are a low-interest rate phenomena.

FTX was simple fraud. This isn't really related and is more standard bank taking on wayy too much risk.

Only indirectly; the tide is receding for the first time in many years, and it's exposing a variety of... issues.

Given the timing one wonders if Silvergate had more impact on SVB. SVB claimed to have minimal crypto exposure, but one wonders what might come out as the FDIC digs deep into their books.

But mostly this was because they bet the farm on long duration bonds just before a period of rising interest rates. It's not like nobody saw that rising rates were on the horizon.

I'd say they're unrelated. This situation could hit any US bank that placed the wrong bet. What's somewhat unusual, and might shelter other banks, is the bank run was viral among VC-backed firms. They also had a stronger incentive to withdraw a lot more because their funds weren't insured. A bank with lots of retail customers doesn't have this issue.
