Capital Economics said on 9 October 2025 that the return of La Niña could affect agricultural production in key exporting regions. The firm expects a weak and short episode, so the broader impact on agricultural prices is likely to be small.
Because the episode is expected to be weak and brief, the price impact on feed grains and oilseeds is limited, so buyers should expect only modest support from weather risk.
