Europe is staring down its worst diesel supply crunch in years, and Morgan Stanley thinks it’s about to get worse. The bank’s latest research flags a convergence of depleted stockpiles, geopolitical disruptions, and surging refining margins that could push European diesel inventories to multi-year lows by the end of 2026.

The numbers behind the crunch

Northwest European distillate inventories, concentrated in the Amsterdam-Rotterdam-Antwerp hub, have fallen to their lowest levels since 2020. Diesel refining margins have surged approximately 170% in recent periods, making it dramatically more profitable for refiners to turn crude oil into diesel. Refiners are ramping output and even postponing scheduled maintenance to capitalize on those margins.

That maintenance deferral creates its own risk. Refineries that skip scheduled downtime tend to face unplanned outages later, which could make the supply picture even uglier when those delays catch up.

Morgan Stanley analyst Martijn Rats and his team are projecting that European diesel inventories are on track to hit multi-year lows by the end of 2026.

Geopolitics reshaping trade flows

Europe’s energy map has been redrawn since it moved to reduce dependence on Russian oil imports following the EU’s ban on Russian oil product imports, implemented in 2023. In the first half of 2025, diesel and gas oil imports from the Middle East accounted for 43% of total imports into Europe. Middle Eastern refinery operations and export capabilities face their own disruptions from regional geopolitical tensions, meaning Europe has traded one set of supply risks for another.

Why crypto investors should pay attention

Diesel is the workhorse fuel of the global economy. It powers freight trucks, shipping vessels, construction equipment, and agricultural machinery. When diesel prices spike, the cost of moving and producing virtually everything goes up with them, feeding directly into consumer price inflation.

If a European diesel squeeze pushes inflation expectations higher, the European Central Bank faces pressure to keep rates elevated or even tighten further. Tighter monetary policy generally constrains liquidity across all risk asset classes, crypto included.

Energy price spikes tend to strengthen the US dollar relative to the euro, as Europe’s energy import dependency worsens its trade balance. A stronger dollar has historically created headwinds for Bitcoin and other crypto assets priced in dollar terms.

The 170% surge in refining margins signals something broader about commodity market stress. Structural supply problems tend to persist longer and cause more economic damage than cyclical ones, which means this diesel story could remain a macro headwind well into 2027.
