Brent crude rises amid Strait of Hormuz tensions despite Iran’s reopening offer
Brent crude climbed more than 1% on April 28, 2026, as markets remained wary despite Tehran’s proposal to reopen the Strait of Hormuz in exchange for deferring nuclear negotiations. Traders pushed prices higher amid ongoing disruptions to shipping through the key choke point for global oil and gas supplies. The move underscores persistent market anxiety that a diplomatic offer has not yet removed immediate supply risks.
Market reaction and headline price moves
Brent crude rose to about $109.42 per barrel as of 03:30 GMT, marking an 11% gain from the same day a week earlier. Market participants said the uptick reflected concern that any reopening of the strait would be conditional and potentially slow to normalize flows. Analysts noted that short-term risk premia remain elevated while the underlying geopolitical uncertainty persists.
Details of Tehran’s reopening proposal
Iranian Foreign Minister Abbas Araghchi reportedly outlined a plan to reopen the waterway in talks with Pakistani interlocutors that would postpone direct nuclear negotiations with the United States. The proposal, as described by sources familiar with the exchanges, would decouple immediate maritime security from the broader diplomatic impasse. Washington has not issued a public response to the offer, leaving markets to price in both the possibility of reduced tensions and the likelihood of prolonged uncertainty.
Sharp decline in transits through the strait
Shipping-monitoring platforms recorded a dramatic fall in vessel traffic, with just eight ships transiting the strait on the most recent Sunday compared with 19 the previous day. Maritime intelligence data show the drop is stark when set against pre-conflict levels; before major hostilities intensified on February 28, average daily transits were roughly 129 vessels, according to international trade statistics. The sudden contraction in movements has disrupted established routes and forced many operators to seek longer, costlier alternatives.
Estimated production losses and infrastructure damage
Industry estimates place the immediate impact on global output at substantial levels, with one major bank calculating a reduction in oil production of roughly 14.5 million barrels per day. That figure reflects both direct hits to regional facilities and the paralysis of shipping that formerly carried crude and natural gas. Observers say damage to pipelines, terminals and onshore processing hubs, together with attacks on tankers, has sharply constrained the ability of producers to export volumes that had been flowing steadily before the conflict.
Constraints on recovery and logistical bottlenecks
Maritime and logistics experts warn that even if a formal agreement to end hostilities is reached, reopening the strait and returning supply chains to their previous capacity could take months. Authorities would need to inspect and clear mines and unexploded ordnance, repair damaged infrastructure, and work through a backlog of cargoes waiting at ports and anchorages. Insurance and freight costs, already elevated, are likely to remain higher for an extended period, adding to the drag on swift operational recovery.
Investor sentiment and broader market implications
Commodity traders have reacted to the mix of diplomatic overtures and persistent operational risks by keeping positions skewed toward precaution, sustaining price volatility. Physical market tightness has pushed refiners and traders to reassess inventories and sourcing strategies, while energy-consuming economies face higher import bills if disruptions endure. Some market participants say the current premium on Brent reflects not only present shortages but also the chance that supply could be constrained for an extended horizon.
Potential scenarios and policy considerations
Should Tehran’s proposal lead to an enduring ceasefire and a credible, enforceable mechanism for securing the waterway, shipping levels could gradually recover and relieve upward pressure on prices. Conversely, if talks stall or are perceived as tactical moves without rapid operational follow-through, traders say downside to prices will be limited and volatility will remain elevated. Policymakers and energy firms are reportedly evaluating contingency plans that include diversifying supply routes and accelerating storage releases if needed.
Global markets will watch closely for any public response from Washington and for confirmation that Iran’s offer will translate into immediate, verifiable steps to restore safe passage. Until then, Brent crude and other benchmarks are expected to reflect a premium for geopolitical risk alongside the fundamentals of supply and demand.
