Money market accounts use the same vehicle (treasuries) and still manage to be ostensibly safer than smaller banks at the moment. These funds manage their investments by continuously buying new bonds and selling off old thus limiting the risk exposure to all but the most sudden interest hikes.

I think money market accounts don’t sell off old, but rather they hold short dated stuff to maturity. And constantly reset the rate they pay holders.

Of course, they can have counterparty risks. The counterparty is usually unprepared to actually pay up and expects to rollover its debt.

Sometimes that melts down and doesn’t happen:

They also, AFAIK, don’t make loans like mortgages, auto loans, credit card lines, etc. All those loans are subject to the same interest rate risk. They’re not nearly as liquid, either.
