Study: Soybean oil for biofuels has limited food price impact

A recent study found that soybean oil for biofuels has a limited impact on overall food prices.

The United Soybean Board partnered with Purdue University on a food and fuel study to evaluate whether the increased use of soybean oil in biofuels has contributed to the rising retail prices of food products for consumers.

One key element missing from this equation is that only one-fifth of the soybean is oil. Most of the soybean is meal used as a high-quality protein in animal diets. This expanded crush for oil to meet biofuel demand creates increased availability for meal, driving down the price of animal protein products and partially offsetting the growth of oil and bakery prices, leaving the overall “food at home” portion of the Consumer Price Index (CPI) essentially unchanged. The static nature of the CPI can be attributed to meat prices representing a larger share of the CPI than fats and oils.

“The economic model we created links the farm supply of soybeans to retail demand for various food products,” said Jayson Lusk, food and agricultural economist at Purdue University. “What we found, after assessing the impact of rising soybean oil demand on prices at the grocery store, was little change to the CPI. While the increased demand for biofuels pushed up retail prices for oil between 0.16% and 4.41% across different categories, retail animal product prices for dairy, beef, pork, chicken and eggs declined between -0.01% and -0.16%.”

The study found that a 20% increase in the quantity of soybean oil demanded for use in biofuels generates the following price impact breakdown (all else equal):

• Soybean oil increase of 0.16% in retail price for frying and baking, 0.82% in retail margarine price, 4.41% in salad/cooking oil and 0.16% in other oil-containing food items.
• Animal protein decrease of 0.16% in retail egg prices, 0.13% in retail chicken prices, 0.06% in retail pork prices, 0.02% in retail dairy prices and 0.01% in retail beef prices.
• Farm level soybean prices increased 0.73%, farm revenue for soybean producers increased 0.92% and overall crude soybean oil prices increased 8.17%.
