The dollar index fell to a 5-week low after Democrats won control of Congress in the US midterms, raising concerns about gridlock and tech regulation. Weaker crude oil and Treasury yields also weighed on the dollar, while the euro rallied to a 4-week high.
A weaker dollar makes US commodity exports cheaper for foreign buyers, which supports soybean, corn and meal demand, while lower oil supports biofuel and freight costs. The effect is moderate and driven by macro factors rather than physical supply.
