Quarterly Review and Outlook - Second Quarter 2008
Widespread is the notion that inflation is back for good. Many assume that the relative price stability of the past two decades has been irrevocably shattered by "peak oil" and the surging demand by developing economies. Improvement of living standards in those developing countries has caused, and will continue to cause, increasing demand for calories, and final demand for food will outstrip supply. Additionally, the cost of basic materials is lifting production costs, and the cycle of higher food and fuel costs means that the prices of all imported goods to the United States will continue to rise. The fixed income investment conclusion is that inflation is endemic, and since the market does not currently reflect such dire inflation prospects, long dated Treasury securities should be sold. We would be among the first to move to the short dated part of the curve if the economic statistics supported the above view.
Our conclusion is that deflation, not inflation, is, and will continue to be, the essential problem for the U.S. economy and that the optimum fixed income portfolio should consist of treasuries with the longest possible maturities.
