I was quoted by The Wall Street Journal on Saturday discussing how to design portfolios in case one expects deflation or inflation. I said that cash has generally kept up with inflation. What I meant is that over the long run, the total return to cash has been a little above inflation. For example, the Ibbotson SBBI Yearbook 2009 shows that between the beginning of 1926 and the end of 2008, the average return to cash was 3.7% annualized, while inflation was 3% annualized.
However, and particularly after the end of the gold standard and the Bretton Woods system, inflationary bursts have eroded the purchasing power of savings. Therefore, I used Morningstar EnCorr to find annualized returns to different fixed income indexes for the years and compared them with inflation for the period from 1973 through 2008. More  |
