The Ibex slows down after its highs and closes at 20,204 points pending the inflation of the USA.

In the Antin case (Infrastructure Services/Antin), the ICSID award has already been recognized and registered as an enforceable judgment by the federal courts of the United States along with six other renewable energy awards against Spain. According to the newspaper Demócrata, this places the procedure in a clearly enforcement phase: asset search, extension of the judgment registration to other districts, and preparation of seizures. What remains are not major appeals on the merits (the validity of the award), but enforcement procedures: discovery of assets, decisions on immunity of specific assets, and, if applicable, seizure orders and realization of those assets. All this will take place in a context of strong tension with the European Union, which has declared the Antin award illegal as state aid.

Current status of the Antin award in the United States

Demócrata reports that, as of March 2026, Spain already has seven recognized and registered proceedings in U.S. federal courts – including the cases Cube, Watkins, Antin, RREEF, 9REN, NextEra, and InfraRed – for a total of 691 million euros of enforceable debt. This judicial recognition “authorizes creditors to initiate enforcement mechanisms provided in the U.S. legal system, including asset location and potential seizure actions” (article on the UK Supreme Court).

Another analysis by Demócrata details that, thanks to this first block of federal judgments – which includes the Infrastructure Services/Antin case – investors have already requested authorization to register the awards in other federal districts, including the Southern District of New York, aiming to get closer to potentially seizable assets (“Creditors take the step to seize Spain’s assets in the U.S...”).

Ongoing enforcement procedures

From the available information, it appears that in the United States, the Antin dispute is already in the typical enforcement phase of a registered award, with several fronts:

• Territorial extension of the judgment: creditors have requested to register the District of Columbia judgment in other districts (e.g., New York) to expand the asset search radius. This is still an ongoing process, extendable to more federal jurisdictions depending on the award holders’ strategy.
• Discovery of Spanish State assets: Demócrata notes that “formal asset discovery procedures (‘discovery orders’)” have been opened and “subpoenas” have been sent to private entities providing services to Spain and to public bodies linked to the State. The goal is to identify accounts, payment flows, contracts, and other rights subject to seizure under U.S. jurisdiction ([link]).
• Determination of which assets do not enjoy immunity: once assets are located, creditors must convince the judge that these are commercial assets of the State (not diplomatic or military) to be able to seize them under U.S. sovereign immunity law. This filter will be applied case by case.
• Specific seizure orders and possible realization: only after passing the previous phases can the court issue seizure orders on specific Spanish assets in the U.S. Ultimately, sales or direct collections could be agreed upon to satisfy the credit recognized by the Antin award, but sources emphasize that currently we are in the preparatory phase (identification and location of assets).

Impact of the U.S. Supreme Court and EU decisions

Adding to this scenario, the U.S. Supreme Court has rejected Spain’s petition for certiorari in another renewables case (BayWa), which, according to Demócrata, has “definitively cleared the way for U.S. federal courts to hear recognition and enforcement proceedings of renewable awards” (BayWa case). This decision strengthens the scenario in which the Antin case also moves.

In parallel, the European Commission has declared the Antin award to constitute illegal state aid and has ordered Spain “not to pay any compensation based on the arbitral award” and “to ensure that no payment, enforcement, or implementation of the arbitration award takes place,” also reminding that judges must help prevent its enforcement “in third countries” (Commission press release; also summarized by MITECO in this note).

Spain has announced it will invoke this decision in all foreign jurisdictions where renewable awards enforcement is processed, which likely includes U.S. courts. However, the consulted sources do not yet record a specific ruling by U.S. judges on how to incorporate this European order into their own procedures.

What may happen from now on

In summary, in the United States the Antin case is already beyond the discussion about whether the award can be recognized and is in the phase of material enforcement, with three major pending blocks:

• Complete the extension of the judgment registration to districts where Spain is suspected to have assets or payment flows.
• Conclude discovery proceedings and specify which Spanish Kingdom assets in U.S. territory can be classified as commercial and, therefore, seizable.
• Resolve incidents raised by Spain (immunity of specific assets, claim of illegality due to state aid, etc.) and, if dismissed, issue and execute seizure orders and, if applicable, sales of assets until the amounts owed are covered.

No further information is available in the consulted sources regarding specific deadlines or which specific assets could ultimately be subject to seizure in the U.S. in relation to the Antin award.

The International Energy Agency (IEA) was created to guarantee supply security after the 1973 oil crisis and today combines three major competencies: managing the collective response to energy crises, producing data and analysis that guide public policies, and coordinating the transition to safer and more sustainable energy systems. These functions directly influence the global energy market because they shape price expectations, investment decisions, and how governments react to crises such as the war in Iran or blockades in the Strait of Hormuz. Its decisions on strategic oil reserves, market reports, and recommendations on savings or transition to renewables are closely followed by governments, regulators, and companies.

1. Origin and central mission: supply security

According to the newspaper Demócrata, the IEA was created in 1974 “after the oil embargo imposed by several Arab countries on Western economies,” and since then one of its main instruments has been the strategic oil reserves system. Member countries are required to maintain reserves equivalent to at least 90 days of net crude oil imports, totaling around 1.2 billion barrels in public reserves, plus about 600 million in industrial stocks subject to government obligations (Demócrata analysis).

This architecture gives the IEA a key competency: coordinating emergency responses. In March 2026, its member states approved “the largest release of reserves in its history”: 400 million barrels, later increased to 426 million to contain the impact of the war in the Middle East and the Hormuz blockade on crude prices (initial release and increase to 426 million). The European Commission applauded this decision, emphasizing the need for unity and global cooperation (Brussels assessment).

2. Crisis tools: much more than oil reserves

In extreme situations, the IEA acts as a global “technical command center.” According to Demócrata, the agency can:

• Convene extraordinary government meetings to assess supply security and agree on joint measures (urgent summit on the Middle East).
• Recommend demand reduction measures: from awareness campaigns to traffic limits or fuel rationing.
• Suggest fuel substitution, activation of emergency production capacity, or temporary relaxation of certain fuel quality requirements.

In the current crisis due to the war in Iran, the IEA has warned of “the largest supply disruption in the history of the oil market” and that April 2026 would be “much worse than March” for energy markets (March report and April alert). These assessments help governments and companies anticipate rationing scenarios and reconfigure their purchasing and storage strategies.

3. Data, statistics, and analysis that move markets

Another central competency is the production of data and forecasts. The President of the European Commission, Ursula von der Leyen, has described the IEA as a “valuable” organization for “its data and analysis,” which “play a crucial role in guiding” the EU’s energy decisions (speech covered by Demócrata).

The monthly oil reports and medium-term scenarios directly influence the market: Demócrata notes, for example, how the IEA has revised its demand and supply forecasts upward or downward, anticipating surpluses or deficits that shape price expectations (surplus forecast for 2027 and petroleum surplus projections).

This statistical function is so influential that the United States has warned it might leave the IEA if, in its view, it prioritizes the climate agenda over supply security, demanding it refocus on “data and energy security” (debate on the IEA’s mandate).

4. Policy coordination and energy transition

In recent years, the IEA has expanded its mandate toward the energy transition. The agency itself speaks of entering the “electricity era,” with systems “essentially electrified where possible,” according to statements cited by Demócrata at an event on Europe’s energy future (speech on energy integration). It also promotes global commissions on clean transitions focused on people, such as the one co-chaired by Teresa Ribera, aimed at ensuring just and affordable transitions (La Moncloa note).

In parallel, the IEA practices intense “energy diplomacy”: maintaining constant dialogue with major producers and consumers, promoting savings measures, and advocating accelerating the deployment of renewables as a structural response to price and supply crises (alert on energy and food crisis and “irreversible shift” in energy markets).

5. Global governance: member and partner countries

Finally, the IEA has become a forum for global energy governance. Besides its traditional OECD members, it has created a partner countries program that includes major producers and consumers. In 2026, its board approved the incorporation of Nigeria as a partner country, strengthening cooperation on energy security, emergency response system design, data, and technical training (Nigeria joining the IEA).

This network expands the IEA’s capacity to influence the global market: it facilitates coordinated crisis responses, standardizes statistical standards, and creates a discussion space where supply security, climate transition, and economic development intersect.

Overall, the combination of strategic reserves, crisis coordination capacity, production of benchmark data, and leadership in the energy transition means that any relevant IEA statement almost immediately translates into price movements, regulatory changes, and adjustments in company and government strategies worldwide.

Based on the information available in the consulted sources, the text of the Energy Charter Treaty (ECT) does not appear, nor specifically the content of Article 44 on accession, so it is not possible to legally detail “who can accede” and “under what conditions” according to that specific provision. It is confirmed that the ECT is an international treaty on trade and investment in the energy sector, used as a basis for arbitrations against Spain and other States, and that the EU and several European countries have begun their withdrawal considering it incompatible with their climate objectives. From these references, only a general framework can be extracted: it is a treaty open to accession by new subjects of international law (States and, presumably, regional economic integration organizations) through ordinary procedures of signature, ratification, and deposit, but without being able to specify the technical requirements set by Article 44.

What we do know about the Energy Charter Treaty

Spanish and European sources describe it as a multilateral agreement on trade and investment in energy. The European Commission recalls that the EU adhered to the ECT “with partner countries worldwide as part of its external energy policy” and that this treaty contains an investor-State arbitration offer that has led to numerous awards against Spain for renewable energy cuts, to the point that a U.S. Government brief before its Supreme Court emphasizes that “Spain gave unconditional consent […] by being subject to Article 26 of the Energy Charter Treaty” as reported by Demócrata in this report.

A European Commission press release explains that the EU has notified its withdrawal from the ECT for being incompatible with the Green Deal and the Paris Agreement climate objectives, and that the withdrawal has been communicated to the Government of Portugal as depositary of the treaty, confirming that this is a classic agreement governed by international treaty law (Commission note). In Spain, the Ministry for the Ecological Transition has reported various awards on renewables based on the ECT, highlighting that some arbitral tribunals admitted jurisdiction precisely under this treaty (MITECO statement).

The newspaper Demócrata has documented how the ECT has become the axis of the dispute over compensation to foreign investors in renewables: the association Anpier criticizes that Spain compensates international funds under the Energy Charter while maintaining cuts to small national producers (Demócrata analysis). Another recent piece explains that the European Commission is investigating whether the payment of a 23.5 million euro award to a U.S. fund, derived from arbitration under the ECT, constitutes illegal state aid incompatible with EU rules (news on aid investigation).

Limits of information on accession requirements

Despite all this political and contentious context, none of the located sources reproduce the text of Article 44 nor the procedural articles of the ECT. There are no formulas such as “any State that…” or “any regional economic integration organization that…”, nor the deadlines, reservations, or specific conditions for accession of new members.

In general terms, by analogy with other multilateral treaties referred to in the press (such as the EU-Mercosur agreements or the future fossil fuels treaty mentioned by the Parliament of Navarra in this regional debate), it can be assumed that the ECT provides for:

• A legitimized subject for accession (usually States and, where applicable, regional economic integration organizations).
• A formal acceptance of the treaty by the State or organization, through signature and ratification or accession before the depositary.
• An entry into force period for the new member after depositing the instrument of accession.

However, these are generic features of conventional international technique, not information directly extracted from the ECT text or its Article 44. Demócrata itself, when analyzing other treaties, emphasizes that a State that has freely accepted a treaty “cannot use its internal legislation as justification to breach international commitments,” citing the Vienna Convention on the Law of Treaties in the context of the ECT and awards against Spain (same U.S. Supreme Court piece), but it does not delve into the accession articles.

Conclusion

From the Spanish political and legal perspective, the ECT appears in the sources as a treaty that has allowed investor arbitrations in energy against the State, currently in the process of abandonment by the EU and several member states. However, the text of its Article 44 nor an official description of the specific accession requirements are not available in the consulted sources; therefore, it is not possible to rigorously detail, based on these sources, which countries or organizations can accede to the treaty nor under what exact conditions. For a strictly legal analysis, one would have to refer directly to the official text of the ECT and its organizational statute, which are not found in the reviewed documents.
