Since the advent of fiat money there is only inflation. Most if not all the major economies are constantly (except for brief insignificant periods) expanding money supply. Look at the ratio of the dollar, the Yen, or the Euro to gold over recent years if you need convincing. While Japan suffered a period of deflation from about 1990 to 2003, the Yen was slipping relative to gold by 2000. The Yen remained extraordinarily weak relative to gold and other currencies throughout. It is not a matter of which country will have the strongest currency, but rather which will have the weakest, as we are all in a race to see who can get by with the greatest currency dilution. Because the US is part of the world economy, the degree of inflation we will see in the US is dependent on other currencies as well as Fed policy. The US has had a weak currency policy for a long time. To bet against inflation is to deny reality. It is not a question of whether there will be inflation, but rather how much inflation.
