Logistics premium reshapes soybean oil outlook amid geopolitical tensions

On the first trading day of March 2026, following a joint US-Israel military strike against Iran, Iran immediately announced the closure of the Strait of Hormuz - the critical "chokepoint" for global oil shipments. In response, Brent crude prices surged, and vegetable oil futures price strengthened in tandem.

Amidst high crude oil prices and surging logistics risks, the pricing logic for the vegetable oil market is undergoing a subtle shift. While the sharp rally in CBOT soybean oil was primarily driven by biodiesel demand expectations in the past few days, the market will have to seriously price in the actual supply costs stemming from logistical disruptions. And this logistics premium is unlikely to fade quickly for three key reasons.

First, freight and insurance costs have structurally increased. Shipping lines are already applying emergency surcharges, and the extra time and fuel required for rerouted vessels will ultimately be reflected in delivered prices.

Second, regional trade flows have been severely disrupted. Roughly one-fifth of global palm oil trade transits the Strait of Hormuz. Countries across the Gulf, Afghanistan, and Pakistan, which import nearly 5 million tonnes of vegetable oil annually, now face substantial supply chain interruptions. This will keep both local and global prices elevated over the next one to two months.

Third, supply chain efficiency has deteriorated. Port congestion, shipping delays, and container shortages are already emerging. Even if alternative routes are secured, procurement costs and lead times have already shifted, and they won't be shifting back anytime soon.

The current vegetable oil market has down been dominated by macro-geopolitics, underpinned by logistics costs, with fundamentals temporarily taking a backseat.

In the short term, as long as the Strait of Hormuz remains unsettled, vegetable oil prices are expected to maintain a strong, volatile range. The biggest medium-term risk is a rapid de-escalation of geopolitical tensions. If the conflict ends and the strait reopens, the geopolitical risk premium in crude oil could unwind quickly, leading to a correction in vegetable oil prices. At that point, market focus would likely revert to the underlying global vegetable oil supply-demand balance.

Focusing on the domestic market, soybean oil, as a major vegetable oil consumed in China, is influenced by the aforementioned global geopolitical and logistical factors.

However, its price trajectory is also tightly constrained by soybean arrival schedules and the global outlook for sufficient soybean supplies. This creates a tug-of-war between " support on the macro front" and "pressure from the fundamentals," resulting in a more moderate price trend compared to international soybean oil prices.

Against a backdrop of expected sufficient global soybean supplies, the February USDA report revised its forecast for global soybean ending stocks upward by 1.1 million tonnes to 1.255 billion tonnes, driven largely by higher South American production, which has contributed to inventory builds. The overarching narrative of abundant global soybean supply remains firmly intact.

This supply cushion directly underpins the long-term availability of raw materials for China's soybean oil production. With the country relying on imports for over 80% of its soybean needs, a well-supplied global market ensures a stable feedstock foundation for domestic soybean oil, consistently limiting the upside potential for local prices over the long run.

That structural constraint is a key reason why domestic soybean oil prices continue to lag behind international benchmarks, as well as the more supply-sensitive segments of the vegetable oil complex such as rapeseed oil and palm oil.

Core Conclusion:

Elevated crude oil prices are fueling expectations for biodiesel demand, lifting soybean oil prices in tandem. Yet, soybean oil's gains are tempered by the persistently ample global soybean supply, causing it to lag behind the sharper rallies seen in rapeseed and palm oil.

That said, global logistics bottlenecks are raising the cost of imported soybeans, compounded by emergency surcharges from shipping carriers. These higher freight costs are gradually being passed through to soybean oil prices, offering tangible cost support and reinforcing domestic soybean oil's resilience against downside pressure.

This logistics premium reflects a real increase in import costs. Even if crude oil prices eventually retreat, a portion of these elevated expenses may persist, establishing a higher cost floor and lifting the baseline for any price correction beyond what pure fundamentals would suggest.

In the near term, domestic soybean oil prices are likely to remain elevated and volatile, underpinned by geopolitical tensions and logistics constraints. In the medium term, should tensions ease, the dominant narrative could shift back to ample global soybean supply and rising arrivals in China, potentially triggering a correction phase. However, the embedded logistics floor will likely prevent prices from revisiting previous lows.

At the same time, relatively high domestic inventories and subdued downstream buying interest are exerting growing pressure on basis levels, a trend already visible in recent soybean oil basis movements.
