G7 2026: Iran-US Agreement and Strait of Hormuz Crisis at the Heart of Debates

G7 2026: Iran-US Agreement and Strait of Hormuz Crisis at the Center of Debates in Évian

The G7 summit opens on June 15, 2026, in Évian-les-Bains, amid a regional crisis. Initially planned to address a range of economic and security issues, the annual meeting of the seven major industrial democracies is now dominated by the repercussions of the agreement between Washington and Tehran. This agreement, the details of which remain partially unclear, could reshape the balance of power in the Middle East after fifteen weeks of extreme tensions.

The G7 leaders are meeting in a climate of persistent divisions. While the announcement of a memorandum of understanding between the United States and Iran, scheduled to be signed on June 19 in Geneva, has temporarily calmed the markets, it has also revealed fractures within the G7 itself. Discussions are expected to be tense, particularly regarding the reopening of the Strait of Hormuz, a strategic issue for the global economy.

A Summit Under the Sign of Regional Urgency

The Évian G7 was initially supposed to focus on issues such as post-pandemic economic recovery, the energy transition, and support for Ukraine. However, the Iranian crisis has upended the agenda. Since March 2026, tensions between the United States, Israel, and Iran have led to a surge in energy prices and major geopolitical instability. The Strait of Hormuz, through which approximately 20% of the world's oil transited before its partial closure, has become a symbol of this crisis.

Emmanuel Macron indicated that discussions would cover the US-Iran agreement, support for Lebanon, the reopening of the strait, and an agreement on Tehran's nuclear and ballistic programs. These topics, already complex under normal circumstances, take on a particular dimension in a context where traditional alliances are being tested.

The presence of Arab leaders on the sidelines of the summit underscores the importance given to stabilizing the region. Bilateral meetings are planned, particularly with representatives from Gulf countries, which are directly affected by the fallout from the crisis.

The US-Iran Agreement: A Turning Point with Uncertain Contours

The announcement of an agreement between Washington and Tehran, made on the eve of the summit, has elicited mixed reactions. US President Donald Trump presented the agreement as a victory, claiming it would end the crisis and allow for a resumption of oil exports. In a message posted on social media, he called out to shipowners worldwide: *Ships of the World, start your engines*.

However, the details of the agreement remain largely confidential. Neither the White House nor Iranian authorities have released the full text of the memorandum of understanding. Iranian Deputy Foreign Minister Kazem Gharibabadi stated that the closure of the strait would continue until the official signing of the agreement, scheduled for Geneva. This ambiguity fuels speculation about reciprocal concessions and the guarantees obtained by each party.

Some analysts believe this agreement could mark a shift in US policy in the Middle East. After months of sanctions and military pressure, Washington appears to be opting for a more diplomatic approach, although criticism persists over the methods used. Some G7 countries, particularly in Europe, have expressed reservations about how the negotiations were conducted without prior consultation with allies.

The Strait of Hormuz: A Conditional Reopening

The question of reopening the Strait of Hormuz is one of the most sensitive issues at the summit. Before the crisis, this strategic maritime passage saw around 21 million barrels of oil transit daily. Its partial closure has caused a rise in energy prices and disruptions in global supply chains. The United States and its allies have launched a mine-clearing operation in the area, but risks remain.

The G7 leaders must decide on the deployment of an international mission to secure the strait. Italy and the United Kingdom have already given their principled agreement to participate in this operation, while other countries, such as Germany, remain cautious. France, the host of the summit, is pushing for a multilateral solution, but disagreements over the role of the North Atlantic Treaty Organization (NATO) complicate discussions.

Furthermore, tensions between the United States and Iran over the terms of reopening the strait could delay the resumption of maritime traffic. Tehran is demanding guarantees on the lifting of sanctions before allowing a return to normal, while Washington insists on compliance with the commitments made under the agreement. These differences risk prolonging economic uncertainty.

Persistent Divisions Within the G7

The relationship between the United States and its European allies is being severely tested by the management of the Iranian crisis. Some G7 countries, including France and Germany, have criticized Washington's unilateralism on this issue. President Trump, who arrives in Évian after announcing the agreement with Iran, will have to navigate skeptical partners regarding the long-term benefits of this deal.

British Prime Minister Keir Starmer, in particular, has expressed reservations about the American strategy. London, traditionally close to Washington, fears that this agreement may weaken Israel's position and strengthen Iran's influence in the region. Bilateral discussions between Trump and Starmer are expected to be tense, especially since the United Kingdom has been directly involved in military operations against pro-Iranian militias in Lebanon.

Germany and Canada share these concerns. Berlin has stated that any lasting solution must include a collective approach, respecting United Nations resolutions. Ottawa, for its part, has emphasized the importance of maintaining pressure on Tehran to secure guarantees regarding its nuclear program.

Ukraine and Economic Issues in the Background

Despite the urgency of the Iranian crisis, the G7 has not set aside other major topics on its agenda. The war in Ukraine, which has been ongoing for over two years, remains a priority. Leaders must discuss new rounds of sanctions against Russia and military support for Kyiv. Recent Russian offensives in eastern Ukraine have reignited debates on the effectiveness of the measures taken so far.

Economic issues also occupy a central place. The surge in energy prices, exacerbated by the crisis in the Strait of Hormuz, has repercussions on inflation and global growth. G7 countries must coordinate their monetary policies to avoid a prolonged recession. The question of subsidies for renewable energy and investments in critical infrastructure will also be addressed.

Finally, discussions will focus on the reform of international financial institutions. G7 countries aim to strengthen the role of the International Monetary Fund (IMF) and the World Bank to address future crises. An agreement on this point could be announced on the sidelines of the summit.

Conclusion: Toward Stabilization or New Tensions?

The Évian G7 summit will conclude on June 17, 2026, with mixed results. While the agreement between the United States and Iran paves the way for de-escalation in the Middle East, uncertainties remain regarding its implementation and long-term consequences. The reopening of the Strait of Hormuz, if it materializes, could calm markets, but the risks of new blockages remain high.

Divisions within the G7 show that the Iranian crisis has revealed deep disagreements on the management of regional conflicts. The United States, under President Donald Trump, appears to favor a bilateral approach, while its European allies insist on the need for a multilateral framework. These tensions could weaken the group's cohesion and complicate the search for common solutions.

In the longer term, the success of the U.S.-Iran agreement will depend on both parties' ability to honor their commitments. The coming months will be crucial in assessing whether this deal marks a turning point in international relations or is merely a temporary truce in a broader conflict. In any case, the Évian G7 has highlighted the challenges of a fragmented global governance, where national interests often take precedence over cooperation.
