Concerns over higher borrowing costs and slowing growth drove the sell-off, lowering energy prices and reducing support for biofuel-linked soybean oil and corn demand.

Brent's 5.6% one-day drop on Oct 4 was the largest part of the 5-day decline, driven by weak demand signals.
Documents the Oct 4 plunge (Brent -$5.11 to $85.81) and its magnitude, confirming the move, though it offers limited causal detail.
The sharp crude oil selloff on Oct 4 weakened biofuel-linked demand sentiment for soybean oil, but the timing is earlier than the Oct 9 drop so it is a contributing background factor only.
