Oil prices jump 6% as Hormuz standoff returns in 2026

Oil climbs after tankers are stranded near Hormuz

Oil prices rose in early trading on Sunday after a standoff between Iran and the US prevented tankers from using the Strait of Hormuz, a shipping route seen as crucial to global energy supplies. The move reversed a sharp drop seen earlier, highlighting how quickly prices are responding to developments around the waterway. The latest gains came after more than two days of shifting expectations on whether the strait would reopen for commercial traffic. The situation has been shaped by policy statements, military actions at sea, and uncertainty around a ceasefire timeline.

What the market did in early Sunday trade

US crude oil rose 6.4% to $17.88 per barrel after trading resumed on the Chicago Mercantile Exchange. Brent crude, the international benchmark, climbed 6.5% to $16.25 per barrel. The rise followed a period of volatility that included a steep decline when a potential reopening appeared likely. The sudden shift back upward underlined how sensitive crude is to any threat of supply disruption through the Persian Gulf.

Why the Strait of Hormuz became the focal point

The standoff centers on access to the Strait of Hormuz, the narrow passage linking the Persian Gulf to global markets. The report noted that the strait handled roughly one-fifth of the world’s oil supply before the war began. With tankers unable or unwilling to transit safely, the constraint becomes a direct risk to physical supply, shipping schedules, and inventory planning. The disruption also amplifies uncertainty for refineries and fuel buyers across regions that depend on Middle East crude.

How the announcement on Friday briefly eased prices

Iran, which the report said effectively controls the passage, stated on Friday that it would fully reopen the passage off its coast to commercial traffic. Crude prices plunged more than 9% on that news. The decline reflected expectations that a reopening would reduce the immediate risk premium linked to the route. But the optimism proved short-lived, as subsequent events reversed market sentiment.

Tehran reverses on Saturday as blockade remains

Tehran reversed its decision on Saturday after President Donald Trump said a US Navy blockade of Iranian ports would remain in effect. The reversal brought the possibility of continued shipping constraints back into focus. The market’s quick repricing showed that traders were treating the earlier reopening signal as conditional and fragile. The standoff also raised questions about the durability of any short-term arrangement to allow normal tanker movement.

Weekend incidents: firing on vessels and a reported seizure

Over the weekend, Iran’s Revolutionary Guard fired on several vessels, according to the report. Trump also reported the forcible seizure of an Iranian-flagged cargo ship that tried to get around the blockade. These incidents added an immediate security dimension that goes beyond policy statements. For shipowners and insurers, such episodes can affect routing decisions and willingness to enter the area, even if official announcements suggest a temporary easing.

A war-driven energy shock and uneven regional impact

The US-Israeli war against Iran, now in its eighth week, has contributed to what the report described as one of the worst global energy crises in decades. Countries in Asia and Europe that import much of their oil from the Middle East have felt the most impact from halted supplies and production cuts. At the same time, rapidly rising gasoline, diesel, and jet fuel prices have been affecting businesses and consumers worldwide. The report framed the crisis as both a supply-chain disruption and a downstream fuel-cost problem.

Volatility since Feb. 28 and where prices were before the war

Crude has fluctuated sharply since the US and Israel attacked Iran on Feb. 28, followed by Iranian retaliatory airstrikes on other Gulf states, the report said. Before the conflict, crude traded at roughly $10 per barrel. During the war, it spiked to more than $119 at times. The report added that prices previously closed on Friday at $12.59 for US oil and $10.38 for Brent, illustrating how quickly the market has been repricing risk.

Why normalization could take months even after a deal

Even if a lasting deal to reopen the Strait of Hormuz emerges, analysts cited in the report said it could take months for oil shipments to return to normal levels and for fuel prices to go down. The report listed backed-up tanker traffic, ship owners concerned about another sudden escalation, and energy infrastructure damaged during the war as key obstacles. In other words, reopening the passage may not immediately translate into normal shipping volumes. Capacity, confidence, and infrastructure repair would likely influence the pace of recovery.

What to watch next: ceasefire clock and shipping confidence

A fragile, two-week ceasefire between the US and Iran is set to expire on Wednesday, the report said, and rising tensions in the strait have put the prospects for new talks in question. Separately, a market commentary quoted in the broader coverage said oil markets were reacting to “oscillating social media posts” rather than “realities on the ground,” reflecting continued uncertainty around how quickly flows can resume. In the near term, the key variables remain the status of the blockade, the safety of vessel transits, and whether commercial operators regain enough confidence to move cargo at scale.
