Diesel Rally Drives US Animal Fats and Oils to Multi-Month Highs

Why It Matters

Higher feedstock prices boost renewable‑fuel margins but squeeze producer profitability, while global trade and certification trends reshape the US animal‑fat supply chain.

Key Takeaways

• Diesel rally lifts US animal fat prices to multi‑month highs
• Gulf hub leads with used cooking oil up 23% YTD
• Feedstock cost surge threatens renewable diesel profit margins
• Brazil and Australia imports reshape domestic fats supply

Pulse Analysis

The recent rally in diesel and heating‑oil futures has rippled through the renewable‑fuel supply chain, pushing prices for animal‑based feedstocks such as used cooking oil, tallow and distiller’s corn oil to their highest levels in months. In the US Gulf, the primary renewable‑fuel hub, used cooking oil now trades near 68 cents per pound, up roughly 23 % since the start of the year, while tallow and corn oil have posted eight‑month and three‑year peaks respectively. Higher diesel margins make biodiesel and renewable diesel producers more aggressive bidders for these fats, tightening domestic supply.

Despite the headline price gains, many producers warn that elevated feedstock costs are eroding real profitability. The spread between distillers corn oil and soybean oil has narrowed, and cash diesel often trades below futures, limiting the margin capture that futures prices suggest. Geopolitical shocks, such as tensions involving Iran, have added short‑term spikes to heating‑oil futures, but analysts expect the market to revert to fundamentals once the news cycle subsides. Consequently, net income margins remain under pressure even as gross margins improve.

International dynamics are also reshaping the US animal‑fat market. Recent tariff reductions have opened the door for increased Brazilian tallow and Australian bleachable fancy tallow imports, adding competitive pressure on domestic renderers. At the same time, demand for certified feedstocks under the International Sustainability and Carbon Certification (ISCC) scheme is rising, driven by export opportunities in renewable diesel and sustainable aviation fuel. Looking ahead, the pending Renewable Volume Obligation proposal from the EPA could further influence demand, but short‑term price trajectories will likely stay tied to diesel and vegetable‑oil market movements.
