While both WCE canola prices and CBOT soybean prices have appreciated during the month of August, WCE canola prices have increased at a faster pace. As a result, the nearby WCE canola - CBOT soybean spread has increased to a $67.53 per metric tonne premium at month end, the highest premium seen since July 2003. As recently as May 2004 WCE canola traded at a discount that exceeded $100 per metric tonne to CBOT soybeans, a time when a severe shortage of soybeans was anticipated in the United States while Canadian canola supplies were viewed as being sufficient. Due to the size of the current premium for canola futures, trade sources suggest that in spite of concerns about weather damage reducing the size of the canola crop, continued increases in WCE canola prices may be somewhat dependent on price increases in the CBOT soy complex.
The canola board crush margin for new crop canola and soybean oil and meal has dropped considerably from its late winter peak as a result of WCE canola seed prices outpacing gains in CBOT soybean oil and soybean meal prices, (see Chart 3). After spending most of the year trading considerably higher, current margins have fallen to the point where they are similar to the margin at this time last year. New crop board crush margins measure the November WCE canola futures price against the December CBOT soybean oil and soybean meal prices.
