Part I — Situation overview

On 2 October 2026 the G7 heads of state and government decided by videoconference to start releasing strategic stocks immediately, coordinated by the International Energy Agency (IEA — the energy-security organisation of the advanced oil-importing countries). The G7 is the group of the seven leading industrial countries: the United States, Japan, Germany, France, the United Kingdom, Italy and Canada. According to the joint statement, the release will last four months, with heavy front-loading of diesel in the first twenty days. According to French President Emmanuel Macron, holder of the rotating G7 presidency, this means up to 100 million barrels of diesel and crude oil in total could reach the market (24.hu, Portfolio, EUobserver). The leaders also agreed not to restrict energy exports among themselves. The background is that for days Washington had threatened European countries with a diesel export ban if they did not tap their reserves. According to Politico, American diesel accounts for more than half of Europe’s diesel imports. The European Commission’s energy spokesperson stated the same day that the EU fully rejects the American ban, because it would benefit no one and would undermine trust in the United States as a reliable partner. The EU’s oil coordination group meets on 15 October, earlier if necessary (Portfolio, EUobserver). Meanwhile, at home, anomalies came to light around the first instalment, on 30 September, of the 4×5,000-forint diesel support: according to Magyar Nemzet, in some cases the driver’s parents received the money, and according to an ATV news report, petrol and electric car owners also received it by mistake.

MIAK has so far analysed the domestic side of the diesel crisis in several steps. In May, after the release of 575 million litres from the reserve, it proposed a refilling timetable; in July, public stock data broken down by product type; in August, a fuel shock protocol announced in advance. On the diesel support, in September it called for an eligibility rule and an expiry date, and then for a distributional statement. The new element now is twofold. On the one hand, the stock release has become an international, coordinated action to which Hungary, too, has to define its relationship. On the other hand, the diesel support is no longer a plan but a programme in the course of being paid out, whose first instalment has shown data-quality errors.

MIAK’s reading: the purpose of the security stock is to bridge a supply disruption, not to bring prices down. EUobserver also highlighted this, and the Commission’s own oil coordination group concluded this week that there is no immediate security-of-supply problem in the EU. If the reserve becomes a price-management tool, every release leaves a smaller buffer for a real supply shock. So the question is not whether Hungary takes part in the coordinated action, but whether it does so according to a public rule fixed in advance. The same applies to the diesel support: the erroneous transfers are small items in themselves, but they can be corrected before the remaining three instalments.

Part II — Foundations in the literature

Three open-access international reports provide an interpretive framework for the topic. According to the box on price-reducing interventions in the International Monetary Fund’s (IMF) 2024 World Economic Outlook, export restrictions may moderate inflation domestically, but by narrowing world-market supply they raise prices further elsewhere. This is a direct argument for joint, rule-based action against unilateral export bans. Examining the fragmentation of commodity markets, the IMF’s 2023 report concludes that the lack of data on stocks in itself creates uncertainty. It therefore proposes international data sharing, and that multilateral cooperation should make the use of strategic reserves more efficient. On handling severe shocks, the IMF’s autumn 2025 report writes that the authorities should prepare in advance a few severe but plausible scenarios, each with the expected policy response. And new support measures should be temporary and well targeted. Together the three reports say that stock policy is credible if the release rule and the stock level are known in advance, and crisis support measurably reaches the target group. The detailed treatment of the literature — by source, with quotations — is in section 6.4 Literature in detail.

Part III — MIAK’s concrete proposal

MIAK proposes three measurable steps. The first concerns the rule for using the strategic stock, the second the EU consultation of 15 October, the third the remaining instalments of the diesel support.

3.1 A stock-release rule fixed in advance: separating the supply and the price-management purpose (government resolution by 31 December 2026)

MIAK proposes that the Government lay down in a public government resolution the conditions under which Hungary may draw on its crude oil and product stocks. As an IEA member and under the EU stockholding directive, the country holds a mandatory security stock, managed by the Hungarian Hydrocarbon Stockpiling Association (MSZKSZ — the organisation managing the mandatory security stock of crude oil and petroleum products). The rule should distinguish three cases. First: a domestic supply disruption, for example the outage of a pipeline or the refinery. In this case release is the primary tool. Second: a coordinated action announced by the IEA. In this case the size of the Hungarian contribution must be decided with a public justification, showing separately how much of it is diesel and how many days of cover remain afterwards. Third: a purely domestic price-management purpose. In this case release is permitted only if diesel cover stays above a threshold fixed in advance. Every decision must come with a mandatory refilling deadline and a cost estimate. MIAK already asked for a refilling timetable in May; the new element is the decision rule. Its importance is shown by the fact that in May 2026, 425 million litres of diesel left the domestic stock, and now a new international action is starting. According to the IMF’s recommendation (see 6.4.3), scenarios and responses prepared in advance for severe shocks increase the credibility of economic policy. This supplements the G25 energy price shock preparedness plan and the K7 energy-market shock resilience programme point with a decision rule.

3.2 A public Hungarian position before the EU oil coordination meeting of 15 October (by 13 October 2026)

Hungary is not a member of the G7. According to Politico and EUobserver, the export-restriction commitment in the G7 statement applies to trade among the G7 countries. So, in its public form, it is not clear whether it also extends to EU member states that are not G7 members. MIAK proposes that the Government publish, before the meeting of 15 October, the position it will represent. It should contain three elements. First: Hungary supports the European Commission’s joint action against a unilateral diesel export ban. It should ask for the EU–US commitment to be laid down in writing, covering all member states. Second: if further diesel releases are decided within the IEA framework, the Hungarian contribution should follow the rule in 3.1, with the days of cover made public. Third: Hungary should seek issue-based allies among the member states that are likewise not G7 members but are equally affected by the diesel-market shortage. According to the IMF’s 2024 analysis (see 6.4.1), export restrictions raise prices elsewhere by narrowing world-market supply. The interest of small, import-dependent countries is therefore clearly rules-based trade. This is the application of the KP17 issue-based EU coalition-building programme point to a concrete, time-bound decision.

3.3 A payment review before the second instalment of the diesel support (by 23 October 2026)

The remaining instalments of the diesel support arrive on 30 October, 13 November and 7 December (Magyar Nemzet). According to NAV (the National Tax and Customs Administration), asked by Magyar Nemzet, the Hungarian State Treasury transfers the money to the bank account from which this year’s vehicle tax was paid. If there is none, to another account registered with NAV, and failing that, by post. It follows that the money can also reach a person who merely paid the tax but is not eligible. MIAK proposes that NAV and the Treasury publish a short review by 23 October. It should include the number of payments of the first instalment by channel (bank account or post). It should also include in how many cases the account holder differed from the eligible person, insofar as this can be established from the data. It should show how many complaints were received and how many eligible people did not receive the money. For the cases reported by ATV, where the owner of a non-diesel car received support, it should give an item-by-item explanation: whether a vehicle-register data error or a question of legal interpretation lies behind them. The review should also state what data checks will be added before the second instalment. Examples are matching the vehicle’s fuel type against the vehicle register, or allowing eligible persons to designate their own account. Magyar Nemzet also pointed out that under the rule, someone who sold their diesel car after 1 January is also eligible. This is not a payment error but a design question, so the review should treat it separately. The IMF (see 6.4.3) calls for well-targeted support. In practice, targeting depends on the quality of the recipient data. This is an accelerated application of the G20 ex-post impact assessment and the SZ1 targeted support programme points. This review could also be the data basis for the distributional statement MIAK has requested for 30 November.

The three proposals are linked by one principle: the rule for using a crisis instrument, and its result, should be public before the next decision is taken. For the stock, this means the release rule and the publication of the days of cover; for the EU negotiation, the position committed to in advance; for the support, the review before the next instalment. All three fill the same gap that the IMF reports also highlight (see 6.4.2): where there are no known data and rules, both the market and the public assume the worst.

Part IV — Expected effects and risks

Dimension Expected effect Risk
Energy security The reserve remains available for a real supply disruption; the remaining cover is known after a release Because of an overly strict threshold, Hungary may be able to commit less in an IEA action, which could cause diplomatic tension
Economy and prices A predictable rule moderates panic buying and speculation Without releases for price-management purposes, the diesel price may remain higher in the short term, burdening road haulage and agriculture
Foreign policy Hungary is an active, predictable actor in joint EU action against unilateral export bans A public position narrows the room for manoeuvre in negotiations if a compromise emerges at the meeting
Budget The cost of refilling is foreseeable in advance, not incurred after the fact Refilling is expensive at high price levels; a mandatory deadline may force purchases at a bad time
Public administration and support Fewer erroneous transfers in the remaining three instalments, greater credibility for the programme The short deadline burdens the capacity of NAV and the Treasury; a public error rate fuels political debate

The most important trade-off is the strictness of the stock rule. If the threshold is too high, Hungary may look like a free rider in international actions: it enjoys the price effect of the joint release but hardly contributes. If it is too low, the reserve gradually becomes a price-management fund. In MIAK’s view the solution is not a fixed number but publicity. If every decision makes clear how much diesel went out, how many days of cover remain and by when the level will be restored, the political responsibility for the decision is also clear. The proposal could become risky if the publication of cover data is postponed on security grounds. Publishing the aggregate cover expressed in days, however, carries no such risk.

For the diesel support review, the risk is political rather than technical. The public number of amounts sent to the wrong account may be uncomfortable for the government. Silence, however, is more costly: the error may recur in three more instalments and damages the credibility of the whole targeted-support logic.

Part V — Measurability and summary

5.1 What is worth following? (suggested KPIs)

MIAK suggests the following key performance indicators (KPIs). These are suggested indicators, not government commitments.

  • A written commitment, covering all member states, prohibiting restrictions on energy exports. It is worth following the outcome of the EU meeting of 15 October and of the subsequent IEA consultation.
  • The cover of the diesel security stock in days, published after every release decision. Target: publication within 30 days of the decision, and a refilling deadline for every release.
  • The share of diesel support payments transferred to the wrong recipient, by instalment. The baseline for the first instalment is provided by the review; for the fourth instalment, a fraction of it is worth treating as the target.
  • The domestic retail price of diesel compared with the regional average (based on the European Commission’s weekly fuel price report). This shows whether the price effect of the international release reaches Hungarian consumers.

5.2 Summary

MIAK’s request is addressed to the Government and is tied to three deadlines. By 13 October: a public Hungarian position against unilateral export bans, asking for a written commitment covering all member states. By 23 October: a review of the first instalment of the diesel support and improved data checks before the second instalment. By the end of the year: a government resolution on when and under what rule the country may draw on the security stock, and how it will refill it.

Of MIAK’s foundational values, transparency and data-drivenness are at stake here. Transparency, because the emergency reserve is a shared security asset: citizens have the right to know when and why it is used, and how much remains. Data-drivenness, because targeted support is only as good as the recipient data are accurate. Publicly uncovering the errors is therefore not an admission of the programme’s failure, but a condition for fixing it.

Part VI — Justifications and further sources

6.1 Press framing by spectrum

In the business press, Portfolio followed events in three articles, relying on international news agencies and papers (Reuters, Bloomberg, Financial Times). The framing was strong: the EU gave a “sharp reply” to Trump’s demand, and according to a diplomat, member-state officials were “in shock at the blackmail”. The paper also highlighted that the price of diesel in Europe fell by around 7% as soon as the 50-million-barrel EU plan leaked. The market background also featured: weeks earlier the price of diesel had passed 200 dollars per barrel, and China had not issued export quotas to its largest refineries for October. In the mainstream public-affairs segment, 24.hu, in two short news items based on MTI and Reuters, factually reported the G7 decision and the EU condition, and referred to the domestic diesel support in one sentence. ATV covered the domestic side: according to its news report, petrol and electric car owners also received support by mistake (video; based only on the title and the public lead).

In the left-liberal segment, Telex approached the story from the British consumer side: in the United Kingdom the price of diesel per litre passed two pounds (865 forints) for the first time, a rise of nearly 30% in a year. Citing the BBC, the article named the uncertainty around Hormuz and the war in Ukraine as the causes. In the conservative segment, Magyar Nemzet framed the payment of the diesel support as “chaos”, and published NAV’s answer on the rule for transfers to accounts. According to the paper, because eligibility is tied to the situation on 1 January, someone who has since sold their car can also receive support. It called this contrary to the government’s justification. It traced the price rise back to the summer phase-out of protected prices.

In the international press, Politico contrasted American pressure with Macron’s denial: according to the French president, the tone of the discussion was not threatening but constructive. Citing two diplomats, the paper also wrote that the announcement was essentially a confirmation of the March commitment. EUobserver was sharper: Europe’s “reward” is a single sentence in the G7 statement, and the emergency stock is meant for handling supply disruptions, not prices. Al Jazeera highlighted the American domestic political background: the American diesel price hit a record, and before the midterm elections this is a political burden for the Republicans. The articles of AP and Euractiv (Rapporteur) were not publicly downloadable.

6.2 Facts and data

Figures of the G7 decision and the EU reaction (1–2 October 2026):

Data point Value Source
G7 coordinated stock release up to 100 million barrels of diesel and crude oil, over 4 months, with heavy diesel front-loading in the first 20 days Statement by Macron — 24.hu, Portfolio, EUobserver
French counter-proposal at the EU consultation 50 million barrels of diesel (from European stocks) + 50 million barrels of crude oil (IEA members) Reuters — 24.hu, Portfolio; Politico
American request 120 million barrels of diesel over 180 days (EUobserver: the White House proposal to EU leaders); 100 million barrels of diesel over 180 days (Politico: the request addressed to Macron) EUobserver, Politico
Share of American diesel in Europe’s diesel imports more than half Politico
Share of France and Germany in the EU’s strategic diesel stock more than one third Reuters — Al Jazeera
IEA action in March 2026 400 million barrels; of which Europe committed 73 million barrels of refined products Financial Times — Portfolio
Change in gas and diesel prices since February gas +140%, diesel roughly doubled Paula Pinho, the Commission’s chief spokesperson — EUobserver
American diesel record price 6.53 dollars/gallon (in the week before 2 October) EUobserver, Al Jazeera
Record EU diesel prices in 12 member states, including Italy, Belgium, Romania, Poland European Commission — Al Jazeera
Fall in the diesel price after the leaked EU plan around 7% Financial Times — Portfolio
Next meeting of the EU oil coordination group 15 October 2026 (earlier if necessary) Anna-Kaisa Itkonen, the Commission’s energy spokesperson — Portfolio

The sources differ on the size of the American request (120 or 100 million barrels of diesel over 180 days). The two figures probably refer to requests addressed to two different recipients, so the table gives both, by source.

Timetable and payment rules of the domestic diesel support (Magyar Nemzet, based on NAV’s answer):

Element Content
Eligible a private individual who on 1 January was the keeper of the diesel car, failing that its owner; for one car per person
Amount and schedule 4×5,000 forints: 30 September, 30 October, 13 November, 7 December
Those acquiring a diesel car during the year first payment on 30 October, 10,000 forints in total in two instalments
Determination of eligibility / payment NAV / Hungarian State Treasury
Target account the bank account from which this year’s vehicle tax was paid; failing that, another account registered with NAV; if none, postal delivery
Reporting a change of address from mid-October, if the postal payment does not arrive

Earlier, publicly reported data on the domestic security stock: on 14 May 2026, 50 million litres of petrol and 425 million litres of diesel, 575 million litres in total, were released from the security stock (Telex, HVG, 14 May 2026). On 18 July, according to the government, the crude oil stock grew from 44 days in March to 87 days; according to HVG this refers to crude oil, while cover for finished products is lower (24.hu, 18 July 2026; HVG, 17 July 2026). MIAK found no more recent official data broken down by product type. The blog therefore gives no figure for current diesel cover.

6.3 Policy dimensions

  • Economy (programme points) — the decision rule for stock releases as an element of the energy price shock preparedness plan (programme point ID: G25); an accelerated ex-post review of the diesel support payments (programme point ID: G20);
  • Environment and climate (programme points) — the level and refilling of the security stock as the basis of energy-market shock resilience (programme point ID: K7);
  • Foreign policy (programme points) — a public Hungarian position and issue-based alliance-building against unilateral export bans (programme point ID: KP17);
  • Social policy (programme points) — the quality of recipient data for targeted support, the match between eligible person and beneficiary (programme point ID: SZ1);
  • Transport and infrastructure (background material) — the pass-through of the diesel price into the costs of road haulage and public transport.

6.4 Literature in detail

6.4.1 IMF: World Economic Outlook 2024

One of the boxes in the IMF’s autumn 2024 report reviews the tools, beyond monetary policy, with which governments have tried to bring inflation down. Among the tools listed are cuts in import tariffs and export restrictions. According to the report, export restrictions may ease inflationary pressure domestically, but the consequences do not stay within the border:

“…both measures have adverse international spillovers, as they reduce global supply or increase global demand, contributing to further price increases.” (MIAK’s own translation)

Applied to the diesel market: an American export ban could moderate American consumer prices, but in Europe — which, according to Politico, covers more than half of its imports with American diesel — it would have exactly the opposite effect. This effect hits the smaller, import-dependent member states in the least avoidable way. Hungary’s interest is therefore not for the big players to settle the issue among themselves, but for the rejection of the ban to be laid down as a rule, covering all member states (3.2).

6.4.2 IMF: World Economic Outlook 2023

The third chapter of the IMF’s autumn 2023 report examines the geopolitical fragmentation of commodity markets. It finds that history has seen many kinds of fragmentation, from full trade blockades through embargoes to export restrictions, but these have rarely proved lasting. The chapter’s policy conclusions connect to the present situation at two points. First, according to the report, the scarcity of data on consumption, production and stocks in itself creates uncertainty for producers and consumers. It therefore proposes an international data-sharing platform, modelled on the joint data initiative already operating for fossil fuels. Second, it states that innovation and multilateral cooperation can make the building up and use of strategic reserves more efficient, and that this prevents negative spillovers between countries. Translated to the Hungarian situation: for an internationally coordinated stock policy, the minimum on the domestic side is that data on the country’s own stock level and its use be public (3.1). And the multilateral framework, i.e. the IEA and EU coordination, protects Hungary if it actively shapes it (3.2).

6.4.3 IMF: World Economic Outlook 2025

In the section on handling severe shocks, the IMF’s autumn 2025 report treats preparedness as a condition of credibility:

“Authorities should develop a baseline scenario and a few severe but plausible alternatives. Each scenario should come with an outline of possible policy responses, which helps frame private-sector expectations.” (MIAK’s own translation)

Among its fiscal recommendations, the report also states that new support measures should be temporary, well targeted and offset by clear savings. Applied to the strategic stock: the release rule is itself the response assigned to a scenario. If the market and the public know when the state will draw on the reserve and when it will not, there is less panic buying and speculation (3.1). Applied to the diesel support: good targeting depends not only on the eligibility rule, but also on whether the money actually reaches the eligible person. The rapid uncovering of the errors in the first instalment (3.3) is therefore a practical test of targeting.

6.5 International comparison

The IEA was created after the 1973–74 oil crisis so that consumer countries would act in a coordinated way in the event of a supply disruption, not at each other’s expense. Members hold mandatory stocks, and in its history the agency has announced coordinated releases on a few occasions, at times of severe supply disruption. Compared with this, the current action is unusual on two counts. First, according to Politico, part of the volume released from the 400-million-barrel action in March never reached the market, because it was not competitive with cheaper American crude. Second, according to the Commission’s own oil coordination group, there is currently no immediate security-of-supply problem, which means the action is primarily for price-management purposes. According to EUobserver, the IEA framework gives European capitals political cover: they can present the release as a joint action, not a concession.

Among the institutional models of stockholding, the German stockholding association (Erdölbevorratungsverband, EBV) is the frequently cited example. MIAK’s May analysis has already presented the model of this statutory organisation, financed by contributions from market participants. According to Reuters, the French and German reserves together account for more than a third of the EU’s strategic diesel stock. This explains why Washington put pressure primarily on Paris and Berlin, and also why the voice of the smaller member states counts only in joint EU action. The lesson for Hungary: taking part in the international action and protecting the domestic reserve are not mutually exclusive, if the size of the contribution is determined by a rule known in advance.
