A strike at Lufthansa paralyzes airports, while the entire European aviation industry stands on the brink of a systemic fuel shortage. These seemingly distant crises are symptoms of the same deeper fracture: the old mechanisms that fueled globalization have seized up in a collision with a new, unstable reality.
Geopolitical Trigger and the Shockwave. A one-day strike by Lufthansa cabin crew on April 10, 2026, grounded tens of thousands of passengers. The UFO trade union, fighting for shorter working hours and a social plan for laid-off CityLine employees, led to the cancellation of 580 flights in Frankfurt alone. However, this is merely a local aftershock following a much more powerful earthquake.
On the same day, ACI Europe, representing over 600 European airports, sent an alarming letter to the European Commission. It warned that the Union faces a „systemic” shortage of aviation fuel within three weeks. The cause lies thousands of kilometers away, in the Strait of Hormuz, which has been practically blocked since the start of the armed conflict involving the USA, Israel, and Iran.
The numbers are absolute. Before the conflict, an average of 140 ships crossed the strait daily; in the 24 hours prior to the letter's publication, only 7 passed through. The European Union imports about 40% of its refined kerosene via this route, and aviation fuel prices have doubled since the start of the clashes, reaching 1573 USD per ton. At Italian airports in Milan, Venice, and Bologna, refueling restrictions have already been introduced.
Brent Oil Price Fluctuations (approximate values): 2026-02-27: 72, 2026-04-07: 109, 2026-04-08: 94.75, 2026-04-09: 98
A fragile truce, announced by President Donald Trump, brought only temporary relief. Brent crude prices, after a historic 13% drop, bounced back up to 98 dollars per barrel. Markets do not believe in the permanence of the agreement, especially in the context of the Iranian demand for transit fees through the strait—a proposal that Greek Prime Minister Kyriakos Mitsotakis called „completely unacceptable”.
The USA and Israel military operation against Iran, codenamed Epic Fury, began on February 28, 2026. The conflict led to a sharp reduction in maritime traffic in the Strait of Hormuz. Despite the announcement of a two-week truce on April 7, hundreds of tankers are still waiting for the opportunity to pass, and uncertainty regarding the terms of a lasting peace maintains high tension in the energy markets.
The Broken Social Contract. An external energy shock is hitting the internal fractures of European economies. Lufthansa management, rebuffing union demands, explicitly cites economic pressure. Michael Niggemann, a board member, called the strike escalation „irresponsible” in the face of the „sharp rise in aviation kerosene prices.” This is a clash of two logics: management trying to save profitability and employees defending working conditions that are eroding under the pressure of the crisis.
The same mechanism, though on a different scale, is blocking reforms in Portugal. After nine months of negotiations and over 50 meetings, the UGT trade union federation unanimously rejected the „Trabalho XXI” labor market reform project. Unions fear liberalization, precarization, and restrictions on freedom of association. The government, employers, and employees find themselves in a clinch.
„Czekamy na oficjalne stanowisko UGT i możemy zadeklarować, że rząd jest otwarty na dokończenie negocjacji. Przed nami ostatnia faza, która kiedyś dobiegnie końca, ale nie zamierzam dziś ogłaszać ich finału.” (We are waiting for the official position of the UGT and we can declare that the government is open to completing the negotiations. We are facing the final phase, which will eventually come to an end, but I am not going to announce their conclusion today.) — António Leitão Amaro via Observador
The situation is complicated by the stance of President António José Seguro, who announced a veto for the bill if it does not gain support within the Social Partnership. The old model of dialogue, once a foundation of stability, is today becoming a source of paralysis. The center-right government cannot push through reforms, and the left-wing opposition calls them a „declaration of war against workers.”
The State in a Trap of Helplessness. Crises also expose the weakness of state and supranational structures. In its letter to the EC, ACI Europe warns that the Union lacks „any community-wide mechanism for monitoring the production and reserves of aviation fuel.” Facing the threat of paralysis in a sector that generates 851 billion euros in GDP contribution and supports 14 million jobs, Brussels seems unprepared.
40% — of the EU's refined kerosene supplies are imported through the Strait of Hormuz
National governments are also struggling with new challenges, often in an uncoordinated manner. In Spain, the tax agency AEAT is launching a fiscal campaign, warning taxpayers against using ChatGPT. At the same time, its own system, Renta Web, crashes, blocking residents of Valencia and Castilla-La Mancha from accessing tax breaks.
On one hand, AEAT announces increased controls on YouTubers and TikTokers residing in Andorra or Dubai, attempting to tighten the system in the digital economy era. On the other, the basic tool for communicating with citizens fails on its launch day. This shows the gap between the state's ambitions and its real operational capabilities.
One could argue that these are merely transitional turbulences. The truce in the Middle East, though fragile, has been established. Goldman Sachs lowered short-term oil price forecasts, and labor disputes, like the one at Lufthansa, usually end in compromise. History teaches that markets and societies adapt to shocks.
However, the scale and nature of current challenges suggest something more than cyclical fluctuations. Iran's proposal regarding transit fees for the Strait of Hormuz is not a temporary disruption, but an attempt to permanently change the global rules of the game. The impasse in Portugal is not a routine round of negotiations, but a clash over the fundamental shape of the labor market. And ACI Europe's warning speaks of a „systemic” risk, not a momentary one.
The European economy, deeply dependent on imported energy and stable supply chains, enters the peak tourist season with extraordinary fragility. The old maps, on which trade routes and social contracts were drawn, are proving inadequate for navigating a new, unpredictable world.
Spanish Tax Agency Director General Soledad Fernández declared that she personally would not risk entrusting her financial data to artificial intelligence. Meanwhile, entire economies, from airlines to governments, are entrusting their future to something far less predictable: the word of honor of conflicting powers and a narrow strip of water thousands of kilometers away.
