Strait of Hormuz Reopens — But the Crisis Is Far From Over

.

A Waterway the World Depends On

For weeks, one of the most critical shipping lanes on the planet was effectively shut down. The Strait of Hormuz — a narrow passage between Iran and the Arabian Peninsula — normally carries roughly one-fifth of the world's oil supply. Since the United States and Israel launched military operations against Iran in late February, commercial traffic through the strait had ground to a near halt.

That changed, at least temporarily, on Friday. Iran's Foreign Minister Abbas Araqchi announced that the strait was reopening for commercial vessels — tied to a fragile 10-day ceasefire between Israel and Lebanon brokered by the United States.

Global financial markets responded immediately. Oil prices dropped around 10 percent, and stock markets climbed on hopes that energy flows might normalize.

Trump Celebrates — But Conditions Remain Attached

U.S. President Donald Trump called the development "a great and brilliant day for the world" at a rally in Arizona. He has framed the broader conflict with Iran as a negotiation — a "deal" or "transaction," in his words — and suggested further talks could happen as soon as this weekend.

However, Trump made clear that the U.S. naval blockade of Iranian ports — announced after last weekend's negotiations collapsed — would stay in place until, as he put it, the transaction with Iran is "100% complete."

That condition drew a swift and firm response from Tehran.

Iran Pushes Back Hard

Iran's parliament speaker and chief negotiator Mohammad Baqer Qalibaf stated publicly that the strait "will not remain open" if the American naval blockade continues. He also accused Trump of making false statements about the state of the negotiations.

Iran's Defense Ministry added that military vessels and ships connected to what it called "hostile forces" — meaning the U.S. and Israel — remain barred from passing through the strait. All other commercial ships must now coordinate with Iran's Islamic Revolutionary Guard Corps (IRGC), a requirement that did not exist before the war began.

The gap between Washington's public optimism and Tehran's cautious, conditional tone was on full display throughout Friday.

Ships Tried — And Turned Back

Despite the announcement, the reality on the water was messier. Vessel tracking data showed a group of roughly 20 ships — including container vessels, bulk carriers, and tankers — moving toward the strait on Friday evening. Most turned back without completing the transit, for reasons that remained unclear.

The group included three container ships operated by French shipping company CMA CGM. The company declined to comment.

Shipping firms broadly welcomed Iran's announcement but said they needed more clarity before sending vessels through — particularly regarding the risk of sea mines. The U.S. Navy issued a warning to mariners that the mine threat in parts of the waterway was "not fully understood" and advised vessels to consider avoiding the area.

More than a dozen countries indicated after a video conference on Friday that they were prepared to join an international mission to protect shipping in the strait once conditions allow, according to a statement from the United Kingdom.

Nuclear Standoff Casts a Long Shadow

At the heart of the conflict lies a fundamental disagreement over Iran's nuclear program. During last weekend's talks, the U.S. reportedly proposed a 20-year suspension of all Iranian nuclear activity. Iran countered with a three-to-five year pause — a significant gap.

Trump told Reuters that the U.S. intends to remove Iran's stockpiles of enriched uranium (material that can potentially be used to build a nuclear weapon). He described a plan involving heavy machinery and excavation at Iranian nuclear sites. Iran's Foreign Ministry spokesperson responded that no nuclear material would be transferred anywhere.

Two Iranian sources suggested there may be room for a partial compromise on the uranium stockpile question, but senior Iranian clerics used Friday prayers to deliver a defiant message.

"Our people do not negotiate while being humiliated," said cleric Ahmad Khatami.

A senior Iranian official told Reuters that an initial memorandum of understanding could potentially be reached within days, with a comprehensive peace agreement to follow within 60 days. There were also reports of an agreement to unfreeze billions of dollars in Iranian assets — though Trump said at his Arizona rally that "no money will exchange hands in any way, shape or form."

China Watches — and Xi Is "Very Happy"

One major power with enormous stakes in this situation is China — Iran's largest oil customer and a country that has watched the Strait of Hormuz crisis with serious economic concern.

Trump acknowledged this on Friday, posting on Truth Social that Chinese President Xi Jinping was "very happy that the Strait of Hormuz is open and/or rapidly opening." Trump added that he was looking forward to an upcoming visit to China, calling their planned meeting "potentially historic" and saying "much will be accomplished."

The comment underscores how the Hormuz crisis has global dimensions well beyond the immediate parties. A prolonged closure of the strait would affect energy supplies across Asia, Europe, and beyond — making Beijing a quiet but deeply interested party in any resolution.

Lebanon Ceasefire Holds — Barely

The Israel-Lebanon ceasefire, which triggered the strait's temporary reopening, was largely holding on Friday — though Lebanon's army reported several Israeli violations. A drone strike attributed to Israel killed one person in southern Lebanon.

The current conflict with Lebanon was reignited in early March, when Hezbollah — the Iran-backed armed group — opened fire on Israel in support of Tehran, prompting a major Israeli offensive. Lebanese authorities say the campaign has killed nearly 2,300 people.

The ceasefire is set to expire next week. A senior Iranian official expressed hope that a preliminary agreement could extend it — buying more time for broader negotiations.

What Comes Next

Diplomatic talks are expected to resume, potentially in the Pakistani capital Islamabad. A Pakistani source involved in mediation described a possible path: an initial framework agreement first, followed by a comprehensive deal within 60 days.

Whether that timeline is realistic remains deeply uncertain. Fundamental disagreements — on nuclear activity, the naval blockade, sanctions relief, and war compensation — are far from resolved. The optimism of Friday's headlines sits uneasily alongside the hard realities of the negotiations still ahead.
