Iran has shut the Strait of Hormuz once again, blaming the US naval blockade and escalating tensions, even as Washington signals a potential deal could be close.
WEBDESK – MEDIABITES | April 18, 2026
DUBAI: Iran has closed the Strait of Hormuz for a second time in days, accusing the United States of violating commitments and warning that maritime traffic will remain restricted until the blockade is lifted.
Tehran’s move comes just hours after briefly reopening the vital oil corridor, a development that had lifted global market sentiment and raised hopes for a diplomatic breakthrough.
Iranian Parliament Speaker Mohammad Bagher Ghalibaf said the strait would not stay open under continued pressure, adding that access could be subject to Iranian authorization.
Foreign Ministry spokesman Esmaeil Baqaei described the US naval blockade as a “violation of the ceasefire,” warning that Tehran would respond firmly to any escalation.
US stands firm on blockade
The United States Central Command confirmed that at least 21 vessels have been ordered to reverse course since the blockade began earlier this week, underscoring the disruption to one of the world’s busiest energy routes.
US President Donald Trump maintained that the blockade would remain in place unless a broader agreement with Iran is finalized, though he indicated openness to extending the current ceasefire.
Trump has repeatedly expressed optimism about a potential deal, calling negotiations “very close,” while also claiming that Tehran had agreed to hand over its enriched uranium — a claim Iran has firmly denied.
Diplomatic push and regional stakes
Pakistan has emerged as a key mediator in the crisis, facilitating recent talks between US and Iranian officials in Islamabad, raising hopes for a negotiated settlement.
Despite ongoing tensions, Washington continues to push for a wider regional agreement, linking it to ceasefire arrangements in Lebanon and broader Middle East stability.
Fragile markets, rising uncertainty
The Strait of Hormuz handles a significant share of global oil shipments, making any disruption a major concern for energy markets.
Oil prices had declined on optimism over diplomacy, but the renewed closure has injected fresh uncertainty into global supply chains.
With both sides hardening positions while still engaging in talks, the situation remains volatile — leaving the future of one of the world’s most critical maritime corridors hanging in the balance.
