The Fed isn't seeing any inflation, so it's not seeing a reason to raise rates.

But you're right that it doesn't give them much monetary room--I guess if/when the downturn comes resorting to fiscal stimulus be the only answer. Not that the GOP deficit chickenhawks have given any room there: remember when GOP was against deficits? US$ 1T later Pepperidge Farms remembers.

I'm an economic idiot, but the interest rates have started concern me. It's seemed like no one wants to cut them as that might put the brakes on "growth". There are also rumorings of a crash being around the corner. So if a crash does come about, what's the Fed going to do seeing as how rates are already bottomed out?

They started raising rates but then Trump successfully bullied the Fed.

Though inflation had remained low, so it's not clear that it was necessary to raise rates.
