Allan H. Meltzer, a frequent participant in Cato's annual monetary conferences, warns in the Wall Street Journal that the Federal Reserve may be about to lay the groundwork for another Great Inflation like we saw in the 1970s:
The Federal Reserve seems determined to make mistakes. First it started rumors that it would resume Treasury bond purchases, with the amount as high as $1 trillion. It seems all but certain this will happen once the midterm election passes.
Then the press reported rumors about plans to raise the inflation target to 4% or higher, from 2%. This is a major change from the Fed's quick rejection of a higher target when the International Monetary Fund suggested it a few months ago.
Anyone can make a mistake, but wise people don't repeat the same one. Increasing inflation to reduce unemployment initiated the Great Inflation of the 1960s and 1970s. Milton Friedman pointed out in 1968 why any gain in employment would be temporary: It would last only so long as people underestimated the rate of inflation. Friedman's analysis is now a standard teaching of economics. Surely Fed economists understand this....
Yes, a sustained deflation would be a big problem, but it is unlikely in today's circumstances. Countries with a depreciating exchange rate, an unsustainable budget deficit, and more than $1 trillion of excess monetary reserves are more likely to inflate. That's our problem today, and it's another reason the Fed should give up this nonsense about more stimulus and offer a credible long-term program to prevent the next inflation.
