The only reason they need to be refrigerated is the convenience of preventing them from separating. They do fine in the cupboard.
In the other hand I stopped getting Costco bulk sizes because it was frustrating to mix them back in effectively, and the normal sized jars get used quickly
Nut butters with tons of added sugar, oil, and stabilizers don’t need to be refrigerated. But nut butters with an ingredient list one item long do.

Pure nut butters have done fine for me out of fridge. Not sure about when extra ingredients are added.
I guess it -would- cut down on longevity though, as oils go rancid over time. So I would think refrigeration does help, there?
Only if you rarely eat them. They’ll last a few months before going rancid which is fine for many people.
