MFN Under Fire

The head of the World Trade Organization says the trading system has surprised her by holding together. The number she uses to prove it is also the clearest available measure of how much ground it has lost.

GENEVA, October 7, 2026.

Ngozi Okonjo-Iweala has spent much of the past year being asked when the multilateral trading system will break. In an interview with CNN’s Global Public Square with Fareed Zakaria, aired over the weekend of 3 to 4 October and reported on 5 October by ThisDay Live and Social News XYZ, the WTO Director-General gave an answer that was part reassurance and part warning. Seventy-two percent of world goods trade, she said, still moves on the organization’s most-favoured-nation terms, down from around 80 percent. “I will be very truthful and say that even we are surprised by the resilience,” she told the programme, in the wording carried by Social News XYZ.

The qualifier arrived immediately. “It doesn’t mean that the system, it’s resilient, but is it robust? And I don’t think it is,” she said, as rendered by ThisDay Live. Speaking again in coverage published by The Guardian Nigeria on 7 October, she returned to the same theme: “Despite the turmoil and uncertainty in the last year, we are surprised by its resilience and remain grateful for it.”

The timing of those remarks is what gives them weight. Days before the interview aired, trade ministers from the Group of 20 met in Milwaukee, Wisconsin, where the United States opened a direct campaign to loosen the very rule that Okonjo-Iweala’s 72 percent figure measures. Days before that, the WTO’s Dispute Settlement Body established a panel to examine the European Union’s carbon border levy, a case in which eighteen governments reserved third-party rights. A General Council was reported to be meeting in Geneva this week, according to the Week Ahead published by Borderlex on 5 October. The organization’s chief executive is describing a patient who has survived the operation. Several of the surgeons are arguing about whether to perform another one.

Background and context

Most-favoured-nation treatment is the plainest idea in trade law and, for seventy-eight years, the least negotiable. A concession granted to one member must be granted to all. It is what makes a tariff schedule a published fact rather than a bilateral bargain, and it is the reason a customs broker in Da Nang or Durban can look up a six-digit code and know what a shipment will cost before it leaves the factory.

That universality has been eroding for years through preferential agreements, and far more quickly in the past two through unilateral measures. The scale of the shift is visible in work published by Gary Hufbauer and Lu Zhang at the Peterson Institute for International Economics on 2 March 2026 and updated on 7 May. Of 2025 merchandise imports entering under MFN terms, they put the United States at 10.3 percent, the European Union at 79.0 percent and China at 42.4 percent. More than 80 percent of world merchandise trade was MFN-based in 2022. The gap between the American figure and the European one is the single most revealing number in the current argument: the two largest Western economies are no longer operating the same tariff system, even when they describe themselves as defending the same rulebook.

Alan Wm. Wolff, senior research staff at the Peterson Institute and a former WTO deputy director-general, put the American position without softening it in a piece published on 17 February 2026. “The United States has stated that the era of the World Trade Organization (WTO)’s basic rule of nondiscrimination, called ‘MFN,’ standing for ‘most-favored-nation,’ is over,” he wrote.

At the G20 Trade and Investment Ministerial held in Milwaukee on 30 September and 1 October under the US presidency, United States Trade Representative Jamieson Greer made the case formally. “The MFN principle, particularly when applied unconditionally, constrains economies’ ability to effectively respond to distortive policies,” he said in remarks reported by IANS on 1 October. Speaking afterwards, in comments carried by The Hans India on 3 October, Greer said he was “encouraged that members across the development spectrum indicated that they see merit in considering how the MFN principle might be improved.”

The options tabled at the ministerial amount to a menu of ways to make a universal rule conditional. They include targeted exceptions; a looser legal reading of the exceptions that already exist; a review of GATT Article XXIV, which governs customs unions and free-trade areas; closed plurilateral agreements whose benefits would not extend to non-participants; and faster, more automatic trade remedies.

The ministerial produced less than Washington wanted and more than nothing. Ministers agreed a statement against the weaponisation of food through coercive trade actions, and endorsed a “Milwaukee Framework” on excess steelmaking capacity. They failed to reach consensus on forced labour, with the United States, Mexico and Argentina issuing a separate statement. On MFN itself, there was no agreement.

The carbon border case

Running alongside the political argument is a legal one that tests the same principle from a different direction. On 25 September 2026, the Dispute Settlement Body established a panel in DS639, Russian Federation versus European Union, at Russia’s second request, the EU having blocked the first. The complaint targets the EU’s Carbon Border Adjustment Mechanism and alleged export subsidies arising from the free allocation of Emissions Trading System allowances. Russia argues that CBAM created significant trade barriers for covered goods imported into the European Union.

The striking feature of DS639 is not the complainant but the audience. Eighteen third parties reserved their rights: Argentina, Brazil, Canada, China, India, Indonesia, Japan, Saudi Arabia, South Korea, Malaysia, Norway, Paraguay, Singapore, Switzerland, Chinese Taipei, Thailand, the United Kingdom and the United States. That list includes the EU’s closest partners and its sharpest critics, climate leaders and fossil-fuel exporters, and it spans every income band in the membership. Governments that disagree about almost everything else have decided they need to be in the room when a panel rules on whether a carbon levy applied at the border is a legitimate environmental measure or a discriminatory one.

CBAM remains in force while the case proceeds. As of 7 October 2026, no panel composition had been announced. Importers of covered goods should plan on the mechanism applying throughout, because a panel report is years rather than months away, and because the EU has given no indication it intends to pause.

Brussels framed its participation in the proceedings in explicitly systemic terms. The EU told the Dispute Settlement Body it would take part “not to legitimise Russia’s actions, but to reaffirm the EU’s strong support for the rules-based multilateral trading system,” according to Freight News on 28 September.

That sentence is the hinge of the whole story, because the same European Commission has been working on its own departure from unconditional MFN. In January and February 2026, EU Trade Commissioner Maros Sefcovic proposed tying low European tariffs to assessments of partners’ fair practices, an approach that by construction makes the rate depend on the exporter rather than the product. Euronews reported on 20 February 2026 under a headline describing the Commission as targeting the WTO’s key rule in a push to rebalance trade with China.

So the EU is simultaneously the multilateral system’s most prominent institutional defender and one of the two powers actively loosening its own commitment to the rule the system is built on. This is not hypocrisy so much as a sequencing problem: Brussels wants the dispute system intact for the cases it brings and defends, and wants more latitude for the instruments it is preparing against Chinese overcapacity. Whether those two objectives can be held together is the open question of the next twelve months, and Okonjo-Iweala’s falling percentage is the metric that will answer it.

Stakeholder reactions

The counterpoint at Milwaukee came mainly from India. Piyush Goyal, the Commerce and Industry Minister, rejected the American framing in terms that left no interpretive room. “India cannot support making MFN conditional on obligations chosen by some WTO members,” he said in remarks reported by Daily Prabhat and WebIndia123 on 2 October.

Goyal’s defence of the rule was not procedural but distributive. “MFN treatment guarantees that the smallest trader receives the same terms as the largest,” he said, according to Daily Prabhat. That is the clearest statement of what is actually at stake for the bottom two-thirds of the membership. A country with no leverage gets the same tariff as a country with a great deal of it, because the rule says so and not because anyone negotiated it on their behalf. Remove the automatic character of the entitlement and the smallest traders are the first to find themselves at the back of a queue.

He was equally pointed about the vocabulary of resilience that now surrounds industrial policy, arguing that supply-chain diversification “cannot be used as a pretext for measures outside WTO rules or for shifting the burden of adjustment onto developing countries,” in comments reported by Daily Prabhat. And he set out an evidentiary standard that cuts against several of the instruments currently in fashion. “Measures at the border must be based on specific and verifiable evidence rather than presumptions about entire countries, regions or sectors,” he told the ministerial, according to Business Standard on 2 October.

That last line reads as a direct response to the logic of country-wide and sector-wide screening, which is precisely the logic that both Washington’s conditional-MFN proposals and Brussels’s fair-practice tariff concept rely on.

The European picture, meanwhile, is being shaped by a bilateral relationship rather than a multilateral one. Sefcovic travels to Beijing this week for ministerial consultations with Chinese Commerce Minister Wang Wentao, although reports differ on the dates: some give 8 to 9 October, while at least one Reuters rendering gives 10 to 11 October. The backdrop is a goods deficit that Reuters put at around 360 billion euros in 2025 and that now exceeds 1 billion euros a day, as reported on 7 October. Denis Redonnet, the EU’s Chief Trade Enforcement Officer, told AFP on 5 October that import surges were “sustained and abnormal” and showed “potentially worrying trends for almost a quarter of all imports into the EU.” Sefcovic told the same agency that the EU wants “a system of export licensing for rare earths and other products.” Reuters reported on 7 October that European Commission President Ursula von der Leyen had described the situation as having reached a tipping point and said Europe would use all the tools at its disposal.

Expectations for the Beijing meetings are modest. Penny Naas of the German Marshall Fund told AFP on 5 October: “There may be a few crumbs, but I would not expect any kind of major breakthrough.” Zhu Tian, an economics professor at CEIBS in Shanghai, told the agency he expects “agreements on some specific issues, rather than any broad settlement.”

China is not waiting passively. Its Ministry of Commerce opened an anti-dumping investigation into EU-origin p-nitrotoluene on 3 October, following an application filed on 14 September by Jiangsu Huaihe Chemical and Hubei Dongfang Chemical; MOFCOM said EU-origin prices had fallen by nearly 60 percent cumulatively. Beijing counts 28 EU trade-remedy cases against China since 2025, about half of them in chemicals. It banned dual-use exports to 7 European entities in April 2026 and to 14 more in July, covering firms in Germany, Czechia, Poland, France and the Netherlands.

Economic impact analysis

The oddity of this moment is that the numbers have been good while the rules have been deteriorating.

Okonjo-Iweala’s figures, as reported this week, describe a year that beat expectations widely. Global goods trade grew 4.6 percent against a projected 2.4 to 2.5 percent. First-quarter 2026 goods trade grew 3.2 percent against 1.9 percent projected. For context, the WTO’s October 2025 outlook had put 2025 growth at 2.4 percent, up from 0.9 percent, while cutting the 2026 projection to 0.5 percent from 1.8 percent. No October 2026 forecast update has been published that could be located, so the comparison is between her reported figures and the last published baseline.

The composition of the surprise matters more than its size. Okonjo-Iweala attributed 42 percent of the growth to artificial-intelligence-related goods: semiconductors, processors and hardware. And she noted that the benefits were concentrated in East Asia and North America.

Read carefully, that is a far more cautious story than the headline growth rate suggests. Close to half the outperformance came from a single technology cycle, in a product category with unusually concentrated production and unusually concentrated demand, and the gains landed in two regions. A trading system can post strong aggregate numbers while delivering very little to most of its members, and the distribution Okonjo-Iweala describes is consistent with exactly that. It also explains the resilient-but-not-robust formulation. Resilience here is partly a measure of how much weight one booming sector can carry, which is not the same as structural soundness.

There is a further reason to treat the aggregate with care. Trade volumes in a period of tariff escalation are distorted by front-running, as buyers pull purchases forward ahead of announced measures. Nothing in the reported material quantifies that effect. But it is a standing reason why one strong year should not be read as evidence that the rules do not matter.

Against that backdrop, the policy record this week shows the texture of a system still functioning in its ordinary, unglamorous registers. Analyst-verified records in the Global Trade Alert database, modified between 5 and 7 October, include a Eurasian Economic Union suspension of the anti-dumping duty on certain titanium dioxide from China from 3 October 2026 to 10 August 2027, covering Armenia, Belarus, Kazakhstan, Kyrgyzstan and Russia. The Southern African Customs Union, comprising Botswana, Eswatini, Lesotho, Namibia and South Africa, extended a definitive anti-dumping duty on wires, ropes and cables from China, Germany and the United Kingdom while allowing the duty on Korea to expire.

Elsewhere the direction is mixed. Russia is removing the import VAT exemption for specified technological equipment with effect from 1 January 2027, and has brought in public procurement localisation for coronary stents and balloon angioplasty catheters from 1 October 2026. New Zealand introduced liberalising tariff concessions on 1 October. Vietnam extended its removal of import tariffs on petrol, oil and fuel production materials to 31 December 2026. Italy announced poultry and egg support schemes worth 60.7 million euros and a pigmeat scheme worth 12.6 million euros on 6 October. India updated a cluster of railway local-content procurement preferences through 5 to 7 October, several of them above 1,000 crore rupees.

None of these is a headline. Together they are the system Okonjo-Iweala is describing: duties applied, reviewed, extended and allowed to lapse; concessions granted; procurement quietly reserved. That machinery is what the 72 percent measures, and what a conditional MFN regime would replace.

Implications for global importers, exporters and supply chains

For companies, the abstraction has a very concrete form. Under unconditional MFN, the duty on a shipment is a function of what the shipment is. Classify the good, verify the origin, apply the published rate. Under a conditional regime, the duty becomes a function of who made it and how that exporter’s government behaves. That converts a largely static classification problem into a dynamic, country-pair problem, and it is the single most important operational consequence of everything described above.

Four pressure points are already visible.

Rare earths and magnets are the pivot of the EU-China relationship, and the European ask is structural rather than transactional. Sefcovic’s call for a system of export licensing rather than case-by-case approvals is a request for predictability, which is what procurement planning actually requires. Buyers dependent on these inputs should assume continued case-by-case treatment until any standing arrangement is announced, because nothing in the reported material confirms one.

Chemicals have become a two-way battleground. With 28 EU trade-remedy cases against China since 2025, about half of them in chemicals, and China’s 3 October p-nitrotoluene probe running in the opposite direction, buyers of dyes, pigments, pesticide intermediates and pharmaceutical intermediates now face duty risk on both legs of the same trade. Dual sourcing across the two blocs reduces exposure to neither.

Automotive importers face a classification question with real money attached. EU plug-in hybrid imports rose 86 percent with a 20 percent price drop, on top of the existing EV tariffs. That pattern is consistent with tariff engineering through hybrid classification, and it is the kind of pattern that attracts regulatory attention. Importers relying on hybrid classifications should expect scrutiny and should be able to document the engineering rationale independently of the duty outcome.

Dual-use and defence suppliers are now routinely exposed to entity listing on both sides. With 7 European entities restricted in April 2026 and 14 more in July, covering Germany, Czechia, Poland, France and the Netherlands, counterparty screening has moved from a compliance formality to a commercial risk for aerospace and defence firms and their tier-two suppliers.

Underlying all four is the closed-plurilateral option tabled at Milwaukee. Agreements whose benefits do not extend to non-participants would mean that exclusion costs a company the entire preference rather than a margin on it. For a mid-sized exporter in a country outside the club, that is not a change in the rate. It is a change in whether the market exists.

What to watch next

Several near-term markers will show which way this moves.

The European Council meets on 15 to 16 October, and Brussels is preparing new defensive trade instruments for presentation to leaders in December. Their content will reveal how far the Commission intends to take the fair-practice logic Sefcovic floated in February.

The EU-China Trade and Investment Consultations mechanism, launched around 29 June to 1 July 2026 and covering trade balance, investment, export controls, intellectual property and WTO reform, set October 2026 as the deadline for concrete results. This week’s Beijing meetings are the test of that deadline, with the caveat that reports differ on the exact dates and that both the German Marshall Fund and CEIBS voices quoted by AFP expect something narrow.

In DS639, the next observable step is panel composition, which had not been announced as of 7 October. The eighteen third parties guarantee that whatever a panel eventually says about CBAM will be read as a ruling on the legitimacy of climate measures applied at the border, not merely on one mechanism.

And in Geneva, the question is whether the Milwaukee menu migrates into formal WTO processes. Greer said members across the development spectrum saw merit in considering how MFN might be improved; Goyal said India cannot support making the rule conditional. Those two positions cannot both be accommodated in a consensus organization without one of them moving.

Okonjo-Iweala’s distinction between resilient and robust is the right frame for watching all of it. A system can absorb a great deal of strain while its foundational rule quietly shrinks from 80 percent of world goods trade to 72 percent. The number to watch is not next year’s growth rate. It is whether that percentage keeps falling, and how fast.
