Natural Limit To Inflation
Again, I thought that was quite funny and figuratively speaking that is largely true, although it is not likely true in a literal sense. Shortage of trees is unlikely to be an obstacle for Bernanke because first of all most money in America is deposit money rather than paper money, secondly because there are quite a lot of trees available in the world and thirdly because he could always add more zeroes on the notes in the unlikely event such a shortage would occur.
Now, it seems that Zimbabwe's hyperinflation (currently at least 165,000%, with some arguing that it could be as high as a million %) could possibly be contained by a shortage of physical paper. The German company which has so far supplied the Mugabe regime with the paper they need for the money they print, now says it will stop these shipments. So unless the Mugabe regime quickly finds some other supplier, shortage of paper could actually be what stops Zimbabwe's hyperinflation. While Bernanke won't be stopped by shortage of trees and paper, another even more extreme inflationist could be stopped by that.
