Tight Spot for Fed, Blind Spot for Investors

``The 10-year Treasury yield historically averages about 6 percent, with about 3.5 percent inflation and a real yield of 2.5 percent. This reflects the preferences of marginal buyers in the United States. Foreign central banks have pushed down the yield requirement substantially over the past seven years. If marginal buyers become American again, as I believe, Treasury yields will surge even higher from current levels. Future inflation will average more than 3.5 percent, I believe. Some policy thinkers in the United States believe the Fed should target inflation between 5 and 6 percent. The Treasury yield could rise to between 7.5 and 8.5 percent from the current 3.5 percent.''
