The return of Donald Trump to the White House is causing volatility and uncertainty in the cereal markets, as the US is a leader in the production and world trade of corn. Spain, which is a deficit country for cereals, is unsure whether tariffs will be imposed on US grain due to Washington's actions or decisions that reduce supply. The head of the wholesale cereal merchants' association, Accoe, explained that there is an abundance of cereals and oilseeds in the world, but marketing conditions could alter the market. Spanish markets have seen a price increase of approximately 3% to 5% in 2025, and the European stock market operator in Paris saw slight increases in wheat and corn.
