Canola prices have seen a rebound with two consecutive gains, reaching over $20 per tonne for old-crop after an initial drop. This volatility is attributed to significant liquidity in the markets and the actions of funds. Other factors contributing to the price increase include tight old-crop supplies and ongoing dryness in the Prairies. However, prices could switch direction due to developments in the wheat and Chinese soybean and corn markets. The market's unpredictability is expected to persist until Statistics Canada provides crop projections at the end of the month.
