I mean the capacity to produce goods and services. I am not an economist but it seems to me that factories will often run underneath max capacity. I also think that supply chains are more flexible than they were in the past. All cases of hyper inflation I know of always had a concurrent disruption to supply capacity (e.g. war, natural disaster, political strife). It seems ramping up production to meet demand is usually not an issue over the course of a year if there isn't some big externality preventing it (i.e.war). I'd be interested hearing from people who know more if this is the case.
