There are studies, but the studies are flawed. It depends very much on the country/union. The US raising rates will absolutely slow/stop inflation in the US, and at least slow down worldwide inflation. North Korea? yeah, good luck… Outside of those extremes, it depends on the population of the country/union and how widely the currency is used. I saw an NPR piece mentioned by trog, but that does not change my viewpoint. The NPR piece appears to not focus on currency usage %, which is why I think it isn’t all that relevant.
