Do Central Bankers Have A Natural Disdain for Forex Trading?

I am thinking the jobs of Central Banks would a lot simpler if the world had only one currency.

How nuts is this thought?

I think most of them would be out of a job

I think central bankers have a natural disdain for higher interest rates (Paul Volker the last great central bankers as the exception)

While the only job of a politician is to seek reelection, the only job of a central banker is to make sure the economic crash doesn’t happen on their watch
