Strait of Hormuz Reopens: Oil Drops 10% in 2026

What Iran announced on April 17

Iranian Foreign Minister Abbas Araghchi said on April 17 that the Strait of Hormuz was open for commercial vessels following a ceasefire accord agreed in Lebanon. In a post on X, Araghchi said the passage for all commercial vessels through the strait was “declared completely open for the remaining period of ceasefire.” He also indicated that vessels would need to pass along a route announced by Iran’s Ports and Maritime Organisation.

The strait is a vital corridor for global trade in oil and other commodities, and restrictions in recent weeks have been closely watched by energy markets and shipping firms. The reopening follows weeks of conflict and disruption, with references in the provided coverage to nearly seven weeks of turmoil.

Trump acknowledges reopening but keeps blockade

Soon after Araghchi’s statement, US President Donald Trump posted on Truth Social that Iran had announced the strait was “fully open and ready for passage.” But Trump added that a US military blockade of ships sailing through the strait to Iranian ports would remain in place.

Trump said the blockade would “remain in full force” until “our transaction with Iran is 100 per cent complete.” He also said the process should move quickly because “most of the points are already negotiated.” In separate remarks reported by multiple outlets, Trump suggested talks could happen as soon as the weekend and said a deal could be secured “in the next day or two,” according to an Axios account.

Where talks stand after Islamabad round

The US blockade was announced after talks with Iran last weekend in Islamabad ended without agreement. Islamabad is again being discussed as a possible venue for a further round, but the coverage also notes that, by the afternoon of April 17, a weekend meeting looked increasingly unlikely due to the logistics of assembling officials in the Pakistani capital.

Several reports described discussions spanning frozen Iranian funds and Iran’s enriched uranium stockpile. At the same time, no agreement, venue, or formal date had been confirmed.

Nuclear issues remain the main sticking point

Iran’s state media outlet Mizan disputed parts of the reported negotiations. It said there had been no negotiation about transferring Iran’s highly enriched uranium to the United States and “naturally there is no agreement on this matter either,” citing sources.

Trump, in various comments carried across outlets, said the core US demand was that Iran should never be able to develop a nuclear weapon. He also said Iran had agreed to turn over its stock of enriched uranium, and elsewhere it was reported he said the US would retrieve enriched uranium from Iran. Tehran’s position, as stated in the coverage, is that its nuclear programme is peaceful and that civilian enrichment is a national right.

Ceasefire links: Lebanon and the wider conflict

Araghchi framed the Hormuz reopening as being in line with the Lebanon ceasefire. Trump, in a separate post, said the Iran deal was “not tied, in any way, to Lebanon.”

The wider timeline in the provided material includes a two-week ceasefire announced on April 7. It also says the US-Iran war began on February 28 with major combat operations and joint US-Israeli strikes targeting military and government sites.

Shipping and security risks in the strait

Despite the announcement that the channel was open, security concerns remained in the reporting. A US navy advisory said the mine threat in parts of the Strait of Hormuz was “not fully understood” and that avoidance of the area should be considered.

Trump also claimed the United States and Iran were working to remove sea mines from Hormuz, describing Iran as removing all sea mines “with help of the US.” The provided coverage does not include independent confirmation of that claim.

Immediate market reaction: oil down, stocks up

The reopening announcement and associated signals on talks moved markets quickly. Oil prices fell more than 10 per cent, and US stock markets rose following the development, according to the Firstpost segment included in the material.

The energy market sensitivity is underscored by references that the strait had been largely shut since the start of the conflict, contributing to earlier price spikes. One report also cited a tracking firm, Kpler, saying three Iranian oil tankers carrying five million barrels of crude were the first such loaded vessels to leave the Gulf through Hormuz since a US blockade came into force.

Market impact: what the signals mean for investors

For markets, the key distinction in the reporting is between the reopening of a global shipping corridor and the continued US blockade affecting access to Iranian ports. The first signal reduced near-term disruption fears, which aligned with the reported drop of more than 10 per cent in oil prices and a rise in US equities.

But the continued blockade, and the conflicting accounts on nuclear provisions, show that core issues were still unresolved even as both sides talked up progress. The risk picture also remained shaped by security warnings, including the US navy advisory on mines.

Why this matters: leverage versus de-escalation

The latest developments point to de-escalation in navigation through Hormuz while maintaining economic and military pressure through the blockade. Trump’s repeated phrasing that the blockade stays until the “transaction” is complete highlights how the US is presenting the blockade as leverage while negotiations continue.

Iran’s announcement, tied to a ceasefire period, suggests that navigation access could depend on the durability of broader regional arrangements. Meanwhile, Mizan’s denial on uranium transfer discussions indicates that even widely reported deal components may be contested publicly.

What to watch next

The next major marker will be confirmation of whether US-Iran talks resume in Islamabad and whether any formal date, venue, or framework is announced. Official clarity on nuclear steps, including the status of enriched uranium, will also be central given the contradictory claims reported.

Until then, the reopening of the Strait of Hormuz changes the immediate flow outlook for energy and shipping, while the continued blockade keeps geopolitical risk priced into the region.
