WORLD GRAIN TRADE RECOVERY MAY BE UNDERWAY World grain trade could be turning the corner and heading toward recovery in the 1986-87 season, a Cargill, Inc. analyst said. Writing in the March issue of the Cargill Bulletin, David Rogers of Cargill's Commodity Marketing Division cited a gradual rise in world wheat trade in recent months, with a slow rise in wheat prices after recent historic lows. He said the wheat trade, because wheat can be produced in many nations, is a good barometer of world grain trade and could lead to more activity in other grain markets. Rogers said that with world grain prices at their lowest level in over a quarter of a century in real terms, demand has begun to rise while producing nations are re-examining their expensive price-support policies and reducing planted acres.
