CME Sets June 6 Launch Date For Fertilizer Futures And Options Contracts

Date 19/05/2004

Chicago Mercantile Exchange Inc. (CME) today announced it would launch trading in its new fertilizer futures and options on futures contracts on Sunday, June 6 at 5 p.m. Central time. The contracts, based on three of the most commonly used varieties of fertilizer, will trade exclusively on CME’s GLOBEX® electronic trading platform.

The three products - diammonium phosphate (or DAP, which is 18 percent nitrogen and 46 percent phosphate), urea (46 percent nitrogen), and urea ammonium nitrate (or UAN, which is 32 percent nitrogen), together have combined annual sales of $4 billion to $6 billion in the U.S. Over the past five years the price variability of the commodities underlying the contracts has ranged as high as 50 percent.

The contracts will be sized at 100 tons each, and will be listed with expirations in March, May, July, September and December. The minimum price movement will be $0.50 per ton. Expiration will be on the last business day prior to the 16th calendar day of the contract month. Options on futures will expire on the first Friday of each contract month. The contracts will trade on CME’s GLOBEX system Sunday through Thursday from 5 p.m. to 3:15 p.m. the following day. Trading on expiration day will cease at 12 noon.

The contracts call for physical delivery from the seller’s choice of origin to the buyer’s destination, using rail based transportation paid for by the buyer, which replicates the practice of the underlying cash markets.
