According to WPB, German bitumen production fell by around 16% year on year to approximately 1.17 million metric tons in the first half of 2026, with the steepest declines concentrated in May and June as disruptions to heavy crude supply altered refinery feedstock patterns across Germany and parts of Central Europe. The decline provides one of the clearest measurable indications so far of how this year’s disruption in Middle Eastern crude flows reached the downstream bitumen market, moving beyond higher shipping costs and supply risks to an actual reduction in refinery output.
Data attributed to Germany’s Federal Office for Economic Affairs and Export Control, BAFA, show that bitumen production dropped to approximately 247,000 tons in May, more than 30% below the same month of 2025. June production recovered slightly to around 254,000 tons but remained roughly 20% below the year-earlier level. Based on the reported 16% year-on-year decline, Germany produced roughly 220,000 metric tons less bitumen in the first six months of 2026 than during the comparable period of 2025, with much of that shortfall occurring during the core European road-paving season.
Industry reporting has linked a significant part of the production decline to tighter availability of heavy, sour crude grades suitable for bitumen production following disruptions to Middle Eastern supply. The distinction between the official production data and the market explanation is important: the output decline is measurable, while the connection to feedstock quality reflects refinery and industry assessments of what occurred during the period.
The type of crude entering a refinery has a direct influence on the amount and characteristics of the heavy residue available for bitumen production. During atmospheric distillation, lighter fractions including gasoline, kerosene and diesel are separated from crude oil, after which the heavier material is processed under vacuum to recover additional products. The remaining vacuum residue is one of the principal feedstocks for conventional refinery bitumen, and heavier crude grades generally yield more of this material than lighter grades.
This means that a refinery does not need to shut down for bitumen output to fall substantially. A plant may continue operating at relatively high throughput while producing less bitumen if its crude slate shifts toward lighter barrels, leaving less suitable heavy residue after processing. At the same time, refinery economics may favor maximizing diesel, jet fuel or other middle distillates, further reducing the volume of heavy material directed toward bitumen production.
This mechanism appears to have been particularly relevant to refineries supplied through the Transalpine Pipeline, or TAL. The pipeline transports crude from the Port of Trieste through Italy and Austria into Germany and connects with the Czech MERO network, supplying several major refineries across Central Europe. Its network extends roughly 753 kilometers, while the TAL-OR branch carries crude from Lenting to the MiRO refinery in Karlsruhe.
MiRO states that it receives crude through the Transalpine Pipeline from Trieste and processes feedstock originating mainly from North Africa, Eastern Europe and Central Asia, and the Middle East. The refinery has annual crude-processing capacity of around 15.8 million tons and vacuum-distillation capacity of 7.2 million tons, making its crude slate particularly relevant to the German bitumen market. MiRO reported production of approximately 600,000 tons of bitumen in 2025, illustrating the scale of its contribution to domestic and regional supply.
During May and June, industry reports indicated that the crude mix transported through TAL became lighter as the availability of heavier Middle Eastern grades tightened. Such a shift would not stop bitumen production altogether, but it could reduce the yield of suitable heavy residue while increasing the refinery’s ability and incentive to produce lighter and middle-distillate products. In a market already entering the main paving season, even a temporary reduction in residue availability could quickly translate into tighter bitumen supply.
The disruption also extended beyond Germany. Through its connection with the Czech MERO system, TAL helps supply the Litvínov refinery operated by ORLEN Unipetrol, an important source of petroleum products for Central Europe. Litvínov also matters to Germany because bitumen can move from the Czech Republic into the German market by truck, providing an additional source of supply when domestic availability becomes tight.
ORLEN Unipetrol formally declared a force majeure event in March 2026 after geopolitical escalation and disruption to raw-material supply seriously threatened crude processing at Litvínov and affected other production units. The refinery subsequently faced additional technical constraints, reducing flexibility at a time when regional supply chains were already under pressure. On June 30, the company announced the end of the force majeure event, stating that the availability of crude oil and other raw materials had improved sufficiently for contractual obligations to be met again.
The timing is broadly consistent with the wider bitumen market picture. The sharpest declines in German production occurred during May and June, while physical supply conditions began to improve later in the summer. Industry reports also indicated that Litvínov placed greater emphasis on middle-distillate production during the tighter period, which would have reduced the amount of bitumen available for truck deliveries into Germany at the same time domestic production was under pressure.
Northern Germany faced its own supply constraints. Market participants reported delays to crude deliveries affecting facilities including the TotalEnergies Bitumenwerk Brunsbüttel and the Heide refinery. TotalEnergies officially lists Brunsbüttel among its German bitumen facilities, while Klesch Group operates the Heide refinery. During the tightest phase of the market, some suppliers reportedly restricted spot offers in order to protect deliveries under existing term contracts to customers in Germany and neighboring northern European markets.
This distinction between term and spot supply helps explain why buyers could experience a much tighter market even while refineries remained operational. A producer may continue fulfilling contracted volumes while offering little or no additional material for immediate purchase, leaving buyers without secured allocations exposed to a much sharper reduction in availability. Physical market stress can therefore appear before refinery utilization data alone suggest a severe disruption.
The timing of the production decline intensified its impact on downstream users. Germany’s road-construction season usually gains momentum from April, with paving activity and bitumen demand increasing through spring and early summer. The steep May and June production losses therefore coincided with a period when asphalt producers and road contractors would normally be consuming substantial volumes of paving-grade bitumen.
At the same time, volatile crude and fuel-oil markets increased uncertainty around replacement costs. Reduced domestic output, tighter Czech supply and restricted spot availability in northern Germany made procurement more difficult, while industry reports suggested that some road and construction projects were pushed back toward September as buyers waited for supply conditions and prices to stabilize. Those delays did not necessarily eliminate demand, but they changed the seasonal consumption profile and created the possibility of deferred projects returning later in the year.
The 16% first-half decline should not, however, be interpreted as a permanent loss of 16% of Germany’s bitumen production capacity. The figure measures actual output during January-June 2026 compared with the same period a year earlier; it does not indicate that an equivalent share of refining assets was permanently shut or removed from service. Production can recover when suitable crude becomes more available, operational restrictions ease and refinery economics shift again in favor of heavier products.
By September, market participants reported a significant improvement in German bitumen availability, while ORLEN Unipetrol’s June statement confirmed that access to crude and other raw materials had improved. These developments suggest that an important part of the first-half shock was temporary rather than structural. Even so, the production already lost during the first six months remains significant, and Germany entered the second half of the year with a substantial year-on-year deficit.
MiRO’s operating data help illustrate why crude composition deserves as much attention as refinery throughput. In 2025, the Karlsruhe complex reported around 4.9 million tons of gasoline production, 6.3 million tons of middle distillates and 600,000 tons of bitumen. The figures show how a large refinery continuously allocates its feedstock across competing product streams, with bitumen representing only one part of a much broader production slate.
When heavy residue becomes less available or margins for middle distillates strengthen, bitumen output may decline even while overall refinery operations remain comparatively robust. This is why headline refinery utilization can provide an incomplete picture of the bitumen market and why feedstock composition, vacuum-residue yields and product economics are essential to understanding physical supply.
Germany’s first-half experience also demonstrates the interconnected nature of the European bitumen market. Domestic production can be supplemented by material from the Czech Republic, the Netherlands, Poland and other regional suppliers, but replacement supply is not frictionless. Loading capacity, available trucks or vessels, storage, transport distance and regional price differences all determine how quickly additional product can move into a shortage area.
When several refineries across the same region are exposed to a common feedstock disruption, that flexibility is reduced. A neighboring refinery cannot easily replace lower German output if it is facing the same shortage of heavy crude or prioritizing the same higher-margin refinery products. This was an important feature of the May-June period, when the supply problem extended across parts of the Central European refining system rather than remaining isolated at a single plant.
The German government also acknowledged broader economic pressure from Middle Eastern supply-chain disruption during the period, citing higher energy costs and continued uncertainty surrounding the normalization of trade flows. For the bitumen market, however, the German production figures offer a more direct measure of the impact because they show an actual decline in output of a road-paving product rather than only a potential exposure to higher costs.
The next key question is whether German bitumen production recovered materially during the third quarter. Improved physical availability by September suggests partial normalization, but availability alone does not prove that production returned to 2025 levels. Monthly production data, the composition of refinery crude slates, middle-distillate margins and cross-border flows from neighboring markets will be important indicators for assessing the extent of the recovery.
The timing of delayed road projects may also matter. If a significant amount of work postponed during spring and early summer returns during the autumn paving window, improved supply could be absorbed more quickly than expected. A market can therefore move from physical shortage toward better availability without necessarily returning immediately to comfortable supply conditions.
Germany’s drop to approximately 1.17 million tons of bitumen in the first half of 2026 ultimately highlights a broader issue for the European market: refinery supply risk cannot be measured by crude throughput or nameplate capacity alone. The type of crude entering the refinery, the quantity of vacuum residue it yields, the economics of competing products and the availability of cross-border replacement supply all determine how much bitumen ultimately reaches asphalt plants and road projects.
The refinery system continued to operate, but changes in upstream crude availability were still sufficient to reduce German bitumen production by around 16%, tighten spot supply and disrupt the normal rhythm of the paving market. For European buyers, the episode is a reminder that crude quality and refinery configuration can influence bitumen availability as strongly as changes in overall crude volumes.
