Economics professor Edmond Seifried declared the era of the investment bank dead on Sept. 22, the opening day of the annual convention for the Iowa Bankers Association. Bankers used the two-day meeting in Des Moines to assess the rapidly changing financial services industry. Seifried and others said recession is likely, $200 per barrel oil is possible, housing in some parts of the country may remain repressed for a decade, and the price bubble for commodities and farmland will burst in a couple of years.
