Soybean Oil Backwardation Collapses While Singapore Diesel Near $190 per Barrel Keeps Distillates Tight

Energy markets continue to show a widening divergence between petroleum distillates and vegetable oil feedstocks. Diesel markets remain structurally tight while soybean oil markets increasingly signal oversupply. This contrast is becoming one of the defining features of the current biofuels market.

The distillate complex continues to display a crisis structure. ICE gasoil backwardation between April and July remains near $259 per metric ton while the April to December spread has widened to roughly $351 per metric ton. That represents 74% percent concentrated on the prompt contract value emphasizing the crisis leve. This backwardation exceeds the level seen during the early phase of the energy shock following the Ukraine invasion in 2022. Such extreme backwardation removes any incentive to store diesel and signals that prompt supply remains critically constrained across global markets.

Asian diesel markets confirm this tightness. In Singapore, 10ppm diesel has recently traded near $189 to $190 per barrel while standard 0.05 percent diesel traded closer to $163 per barrel. Refining margins remain elevated near $41.7 per barrel. Despite these margins, physical deals in the Singapore trading window remain extremely thin as refiners hesitate to sell forward cargoes due to uncertainty surrounding crude supply and logistics disruptions affecting Middle East export routes.

High diesel prices are feeding directly into freight costs. Marine fuel represents roughly 40 to 60 percent of vessel operating expenses. With diesel values approaching $190 per barrel in Singapore, bunker replacement costs approach or exceed $1000 per metric ton. This sharp increase in fuel costs is already limiting forward freight commitments and tightening the movement of refined products and agricultural commodities.

While diesel markets tighten, soybean oil is moving in the opposite direction. The May to July soybean oil spread has collapsed from roughly +0.32 cents per pound to about +0.08 cents per pound. That represents a decline of approximately 75 percent and effectively eliminates the backwardation that had previously suggested tight vegetable oil supply. The flattening curve indicates that the market is recognizing a growing surplus of soybean oil.

U.S. soybean oil inventories continue to rise despite higher Renewable Volume Obligations. Stocks are approaching roughly 2.6 billion pounds, more than 20 percent higher than a year earlier. The increase reflects continued expansion in U.S. soybean crush capacity where meal demand remains the primary driver of processing activity. As crush increases, soybean oil supply grows faster than biodiesel demand can absorb.

Export markets reflect the same pressure. Brazilian soybean oil FOB Paranaguá premiums are now deeply negative, with recent indications around minus 1500 to minus 1600 points relative to Chicago soybean oil futures. Some April cargoes have traded between minus 1100 and minus 1400 while May shipments sit closer to minus 1500 to minus 1600. With freight costs rising alongside diesel prices, exporters may need to push premiums even lower, potentially toward minus 2000 points if futures don't collapse, in order to keep oil moving into global markets.

European biodiesel markets continue to trade but activity remains measured. In the ARAG barge window today FAME traded between roughly $275 and $294 per metric ton over ICE gasoil while RME traded near $350 to $351 per metric ton. UCOME traded between $400 and $410 per metric ton while renewable diesel values remained much higher with HVO Class II trading around $1320 to $1335 per metric ton and HVO Class IV near $1570 per metric ton. The structure remains consistent with feedstock availability and carbon intensity values, with UCOME maintaining roughly a $120 premium to FAME and RME about $60 to $70 above FAME.

Despite the explosive structure in petroleum diesel, biodiesel premiums in Europe did not move materially today. FAME remaining near $280 per metric ton suggests traders are already factoring in the softer vegetable oil structure. The collapse in soybean oil backwardation and growing feedstock availability appear to be anchoring biodiesel premiums even as diesel markets signal severe prompt scarcity.

In the United States the Renewable Fuel Standard credit market weakened today. D4 RIN futures for June traded near $1.451 while December traded around $1.49, both down roughly 4 percent on the day. The drop reflects growing awareness that soybean oil supplies continue to expand and that biodiesel feedstock availability is not currently constrained.

Biodiesel screen margins therefore remain positive but are no longer expanding. With D4 RINs near $1.45 and heating oil futures still elevated, biodiesel production margins remain supported, but the softer soybean oil structure and rising inventories limit the upside for biofuel credits.

The broader picture illustrates the unusual phase of the current energy cycle. Diesel markets continue to price physical scarcity driven by supply disruptions and logistical constraints while soybean oil markets reflect the structural expansion of global oilseed production and crush capacity. As freight costs rise and distillate inventories remain tight, biodiesel continues to play a balancing role in the diesel supply system even as its primary feedstock begins to show clear signs of oversupply.
