Importantly, energy prices, which experienced the largest price spike, underpinned production costs of agricultural products relying on energy and fertilisers. Coupled to this impact was the emerging demand for feedstocks to support production of biofuels. This impact was largely crop-specific and included maize in the United States, vegetable oils in the EU, and to a lesser extent, sugar in Brazil. Mandated consumption targets for biofuels, and other support policies further re-enforced the links between energy and feedstock prices.
