A $3.4 Billion Airbus Loan Threatens the U.S.-EU Tariff Truce

By Daniel Okafor

A single $3.4 billion loan could unravel two of the most consequential transatlantic trade agreements in recent memory. U.S. Trade Representative Jamieson Greer warned on Oct. 26 that a loan the European Investment Bank extended to Airbus in June risks "the violation of the terms of our hard-won [Large Civil Aircraft] deal." That deal is the 2021 truce that paused tariffs on roughly $11.5 billion of goods and ended the longest-running dispute in WTO history.

Greer's office says it still has no details on what he called the bank's "largest loan ever." He has pressed the EU for more information, according to his Oct. 26 statement. The stakes extend well beyond one loan, because the truce was extended in July after the European Parliament approved the broader 15% tariff deal brokered between Washington and Brussels.

A fight over Airbus financing therefore puts both agreements in play at once.

Who is pushing the challenge?

Boeing started this. The U.S. manufacturer asked the government to press Airbus for transparency on the loan back in July, as Reuters first reported. At the time, observers speculated Airbus was using the cash to develop a new jet model.

Greer framed the loan as a return to an old pattern. "I had sincerely hoped that trade-distorting European subsidies to Airbus were a thing of the past," he said in the statement. "For decades, France, Germany and Spain have aggressively supported Airbus, their national champion aircraft manufacturer, to gain an unfair advantage over U.S. aerospace workers and business."

Neither the EIB nor Airbus responded to Fortune's requests for comment.

How much does the broader trade deal protect?

The agreement the Trump administration signed with the EU in July is a pillar of the president's trade policy. It set tariff rates at 15% and committed Europe to invest hundreds of billions of dollars in U.S. projects, including energy and defense.

If the deal unwinds, tariffs could revert to 30% — a level that New York Fed economists have already confirmed weighs on American businesses and consumers. The EU could also trigger its retaliation package, which covers more than $100 billion of U.S. goods.

Georgetown's Marc Busch, a professor of international business diplomacy, argues Europe will not fold on this issue because Airbus sits at the center of the European economy. "There's no way Europe backs away from this one. Airbus is real. It's not a little sideshow," Busch told Fortune.

The numbers back him up. Airbus provides 135,000 European jobs, and about one-third of its revenue comes directly from Europe. The EU will likely move quickly to defend government assistance to a company of that scale, Busch said.

"This is a big deal, and the next step will be tremendously important to get right," Busch said.

How did the aviation dispute begin?

The fight over aircraft subsidies is not new. It dates to 1992, when the U.S. and EU signed an agreement permitting government subsidies for aircraft production.

By the following decade, Airbus deliveries had overtaken its American rivals. Boeing and the U.S. government argued that the European countries backing Airbus were breaching WTO subsidies rules. Washington filed a claim alleging Airbus gained a $200 billion economic benefit from $22 billion in illegal subsidies. The EU filed a counterclaim the same day, alleging Boeing received $23 billion in illegal support through tax breaks and defense contracts.

The WTO ruled in 2011 that both manufacturers received subsidies that were either legally questionable or violative by giving one manufacturer an advantage. With the WTO's permission, the U.S. levied tariffs on $7.5 billion of European goods, and the EU imposed tariffs on $4 billion of American goods.

The 2021 truce ended the 17-year conflict — the longest dispute the WTO has ever heard. That truce was extended in July, continuing the suspension of retaliatory tariffs.

What happens next?

The best case is administrative, Busch said. The EIB opens its books, shows the loan resembles previous lending, and USTR puts the issue to rest. The worst case is a full escalation of U.S.-EU tensions.

There is a concrete escalation path. If the Trump administration takes issue with the nature of the loan, it could impose Section 301 tariffs on the EU. Those tariffs could carry WTO authorization if the EU is found to violate aircraft subsidy rules.

That outcome would, in Busch's words, "amount to the ultimate irony of ultimate ironies." In 2020, the WTO ruled that Trump's tariffs against China were illegal, and the president has repeatedly rebuked the organization, claiming it treats the U.S. unfairly.

"It would be quite something," Busch said, "to imagine the ceasefire ends, we reimpose the Airbus tariffs, and Trump can—for the first time—get up in front of the camera and say these tariffs are WTO-authorized."

For now, the ball sits with the EIB. Its next disclosure — or continued silence — will determine whether a 17-year trade war stays buried or returns to the front of the transatlantic agenda.
