Senior executives at Equinor ASA warned Tuesday that a prolonged blockage of the Strait of Hormuz could prevent Europe from reaching adequate natural gas storage levels before winter, according to a report by OilPrice.com. The warning comes as European storage sites sit at just 35-37% capacity, far below the 50% seasonal average. A 1-3 month disruption would make the situation "highly critical," potentially driving benchmark TTF prices toward €90 per megawatt-hour.
The numbers tell a grim story. Dutch reserves plunged to 5.8% by winter's end. That is the lowest level in a decade.
Storage levels in Germany dipped to roughly 20%, while French sites hovered around 27% when spring began, OilPrice.com reported, citing Equinor's internal assessments. The European Union requires member states to fill storage to between 80% and 90% of capacity before the winter heating season begins. What this actually means for your family.
Households across the Netherlands, Germany, and France burned through reserves at an extraordinary rate last winter. Heavy withdrawals driven by peak heating demand collided with a spike in industrial power consumption. Northwest Europe's storage levels fell below 30% before spring even started.
That is roughly double the EU's overall storage deficit. "A quick resolution could allow Europe to attain a manageable 75% storage level by the end of the injection season," Equinor executives said, according to the OilPrice.com report. "A 1–3 month blockage would make the situation highly critical."
The policy says one thing. The reality says another. European governments designed a system that assumes cheap summer gas fills the tanks for expensive winter demand.
That system is broken right now. An unusual market structure has emerged where summer spot prices trade higher than winter contracts. Dutch TTF seasonal spreads have remained in negative territory at roughly €1.3 per megawatt-hour.
This backwardation destroys the economic incentive to buy gas now and store it for later. Nobody expected this. The inverted price curve has been partially driven by expectations of new global LNG capacity arriving later this year, combined with immediate supply fears tied to the Middle East conflict.
Delays and infrastructure damage at key Qatari facilities have tightened the market. The phase-out of Russian LNG has intensified global competition for spot cargoes. Asia is bidding hard for the same shipments Europe needs.
Italy moved first. Regulators like ARERA and transmission operator Snam introduced financial compensation schemes that pay traders the difference between summer and winter gas prices at the Virtual Trading Point. The goal is simple: make storage economics work even when the market says they should not.
Germany took a different path. Europe's largest economy has historically avoided direct state subsidies to force injections. Instead, the Bundesnetzagentur enforces strict statutory filling targets.
Shippers and network users are legally obligated to meet specific inventory levels. Trading Hub Europe GmbH manages the process, recovering costs through a regulatory storage neutrality charge applied to exit flows and network points. Both sides claim victory.
Here are the numbers. Italy leans on financial support. Germany relies on regulatory mandates.
Both nations remain subject to the same EU-wide rules requiring 80-90% storage fill ahead of winter. Neither approach solves the underlying problem if physical gas flows through Hormuz are cut. The economic toll extends beyond storage math.
Equinor projects that a sustained price spike toward €90/MWh would trigger market corrections, including a 10 billion cubic meter reduction in gas-to-power demand. Industrial users would switch to alternative fuels where possible. Some would simply shut down.
This crisis is not 2022. When Russia invaded Ukraine, Europe faced an existential energy emergency. Germany scrambled to rescue Uniper with a multi-billion-euro bailout.
The utility posted a €40 billion net loss after Gazprom cut supplies. Today, Uniper's finances have improved dramatically. The company won major arbitration damages and has begun repaying government aid.
Germany is now moving ahead with privatizing Uniper, required under European Commission state aid rules to reduce its shareholding to a maximum of 25% plus one share by the end of 2028. That timeline concerns energy analysts. A healthy Uniper signals a market that has healed from the 2022 shock.
But the company remains one of Germany's largest gas importers and a key player in European trading and storage networks. Its privatization assumes a functioning global gas market. A Hormuz closure would test that assumption violently.
Behind the diplomatic language lies a geographic fact. The Strait of Hormuz handles roughly 20% of global oil and LNG trade. Iran has tightened its grip on the chokepoint amid escalating regional tensions, OilPrice.com reported in a separate analysis.
Any sustained disruption would ripple through global energy markets within days. Why It Matters: A 1-3 month Hormuz blockage would hit European households and manufacturers at the worst possible moment — just as storage refill season peaks. The resulting price spike would flow directly into electricity bills, industrial production costs, and inflation figures across the eurozone.
Governments that avoided direct energy subsidies after 2022 would face immediate political pressure to intervene. - European gas storage sits at 35-37%, far below the 50% seasonal norm, with Dutch reserves having hit a decade-low of 5.8% at winter's end. - An inverted price curve has broken the economics of summer storage refill, with spot prices trading above winter contracts. - Equinor warns a 1-3 month Hormuz disruption would be "highly critical," potentially pushing TTF prices to €90/MWh. - Italy uses financial compensation to incentivize storage; Germany relies on legal mandates — neither mechanism works if physical supply is cut. The weeks ahead will test European energy planning. A quick diplomatic resolution in the Strait of Hormuz could still allow storage levels to reach 75% by injection season's end.
That would be tight but manageable. A prolonged blockage changes the calculation entirely. Traders will watch TTF price movements for early signals.
Governments will face choices they hoped to avoid: direct market intervention, industrial demand curtailment, or both. Winter is months away. The decisions that determine whether Europe stays warm are being made right now.
