Hormuz shock puts EU emergency oil stocks rules up for rewrite

The European Commission is preparing to overhaul the rules on EU emergency oil stocks, with a proposal expected before the end of 2026.

Early signals suggest the headline storage obligation will stay. The mix of stocks – and the fuels that count towards them – could change.

The 90-day rule under Directive 2009/119/EC

The current rules are set out in Council Directive 2009/119/EC, adopted on Monday, 14 September 2009.

It requires each member state to hold stocks equal to 90 days of average daily net imports or 61 days of average daily inland consumption, whichever is greater.

The framework covers crude oil and petroleum products. It allows countries to hold stocks through central stockholding entities.

Revision listed as a proposed regulation

The Commission's 'Have your say' portal now lists the revision as a planned initiative under the Directorate-General for Energy (DG ENER). Adoption is scheduled for the fourth quarter of 2026.

The portal records the planned act as a proposed regulation rather than an amending directive.

If confirmed, the new rules would apply directly in every member state rather than through national transposition.

The listing gives the rationale in broad terms.

It says the EU energy security framework needs updating "to reflect the needs of the energy transition, geopolitical shifts and new risks such as climate change, changing demand and supply, and physical or cyber-attacks".

The stated aims include better crisis preparedness, reflecting new fuel needs, and simpler reporting for member states.

A feedback period on the proposal is marked as upcoming, with no dates yet set.

The same language appears in the wider review of EU energy security rules. The Commission opened that review with a four-week call for evidence on Monday, 15 September 2025.

At that stage, a proposal was planned for the first quarter of 2026.

Strait of Hormuz disruption tests the system

The timing reflects events since the start of the year.

Conflict in the Middle East from Saturday, 28 February 2026 cut flows through the Strait of Hormuz to less than 10 per cent of pre-conflict levels, according to the International Energy Agency (IEA).

On Wednesday, 11 March 2026, IEA member countries agreed to release 400 million barrels from emergency reserves – the agency's largest collective action to date.

EU countries contributed around 20 per cent of that release, according to the Commission.

On Tuesday, 31 March 2026, the Commission urged member states to coordinate preparations to secure crude and refined product supplies. It also called on them to defer non-emergency refinery maintenance and increase biofuel uptake.

Commission workshops point to operational gaps

The Commission then ran two online expert workshops, on Thursday, 2 July and Thursday, 23 July 2026.

It framed the revision as a response to weaknesses exposed by the crisis.

It also presented it as a way to modernise the framework for what it called "the ever-changing energy landscape and the new geopolitical and climate reality".

According to a report by S&P Global Commodity Insights, the Commission told participants that the conflict had exposed "concrete operational failures" in the current framework.

Product stocks, biofuels and military fuel

The 90-day net-import baseline appears unlikely to rise. S&P Global reported that the Dutch government saw no clear case for lifting it.

Stock composition may prove more contentious.

S&P Global reported that the Federation of European Tank Storage Associations (FETSA) wants the revised rules to favour refined products over crude oil.

The same report said FETSA wants the scope extended to biofuels and future energy carriers.

It also said the Commission's consultation material noted earlier calls from NATO and member states for specific requirements for diesel, jet fuel and gasoline.

Military needs would be distinguished from civil reserves.

What it means for refiners and stockholders

For refiners, importers and stockholding entities, those questions matter more than the headline number.

A shift towards product stocks would change what is held and where.

Admitting biofuels or other renewable fuels would raise questions over how their quality is maintained and verified through long-term storage.

The current crude-and-products framework was not designed around that issue.

The proposal is due before the end of the year. Its detail on stock composition, eligible fuels and reporting will determine how far the obligations on the industry actually move.
