Brent crude back above $100 after Hormuz seizures

Oil returns to the $100 mark on security fears

Brent crude moved back above $100 a barrel after reports that Iran’s Islamic Revolutionary Guard Corps (IRGC) seized vessels in the Strait of Hormuz, a critical global energy chokepoint. The price move highlighted how quickly crude reacts to disruption risk around the strait, which carries about one-fifth of global oil. Traders have been watching the waterway closely amid repeated openings and closures and rising military friction. The latest reports added to the sense that shipping conditions can shift day to day, even when ceasefire language is in circulation. Oil prices had recently dipped below $100, but fresh incidents pushed risk premiums back into the market. Moves in European gas were also reported in the same period, underscoring broader energy market sensitivity. Equity markets were not the focus of the reporting, but energy-linked stocks were noted to be firmer on the spike. The episode is part of a wider maritime stand-off involving the US and Iran.

Brent and WTI settlement levels from April 22

On ICE Futures Europe on April 22, June Brent settled at $101.91 a barrel, up 3.5% from the previous session. On the New York Mercantile Exchange, June West Texas Intermediate (WTI) settled at $12.96 a barrel, up 3.7%. Those closes captured the market’s immediate reaction to the seizure reports and concerns about access through Hormuz. The day’s gains reinforced that crude was trading with a strong geopolitical overlay. Separate price snapshots in the same coverage described Brent trading just below $100 and front-month Nymex crude at $10.23 on another day, reflecting ongoing volatility. Earlier reports also cited sharp intraday moves, including Brent jumping as much as 7.9% in a prior session. The repeated large swings point to the market’s reliance on real-time shipping and security updates. Oil’s response also reflects how concentrated global seaborne flows are around this corridor.

What Iran’s IRGC said it did in the Strait of Hormuz

The IRGC Navy said it seized two container ships, the MSC Francesca and the Defaminodas, and took them into Iranian territorial waters for cargo and document inspections. Iran said the vessels attempted to pass through the Strait of Hormuz without authorization from the Iranian military. Iran-linked media also reported a third case: Mehr News Agency said the container ship Euphoria was seized while transiting the strait. In addition to the seizures, the UK Maritime Trade Operations reported that a vessel in the strait came under attack from IRGC fast-attack craft the same day. The combination of seizures and reported attacks added to concerns about the practical safety of transit. The reporting did not provide details on ownership or cargo beyond the inspection rationale. Even so, the events were enough to move crude futures sharply higher.

The US-Iran ceasefire narrative and why it mattered to prices

The seizures were reported a day after President Donald Trump announced an extension of a “two-week ceasefire” with Iran, one day before it had been due to expire. In separate reporting, the ceasefire was described as being extended indefinitely. The incidents also followed a week in which talks and deadlines were referenced repeatedly, including a ceasefire scheduled to last until April 22 in one report. The broader episode was framed as a contest over control of access and leverage in negotiations. One account said the actions suggested Iran was trying to use its influence over Hormuz as bargaining power in ceasefire talks. Another strand described the US enforcing a naval blockade targeting traffic tied to Iranian ports while stating it would not impede neutral transit to and from non-Iranian destinations. These differences in scope and timing were reflected in the choppy price action.

Shipping disruption signals traders watched

Shipping indicators in the coverage pointed to extreme stress in traffic flows. Bloomberg tracking data cited in one report said no crossings were observed on April 19 through the strait as of early afternoon in London. The same reporting said at least 13 oil tankers turned back toward the Persian Gulf on April 18. Kpler data showed that on one Saturday during a brief reopening, more than 20 vessels carrying oil products, metals, gas and fertiliser transited the strait, the highest daily count since March 1. By the following Sunday, that number was reported to have fallen to zero. The UK Maritime Trade Operations data cited a pre-war daily average of 138 transits. Investing.com was cited saying tanker shipping had been nearly halted for almost two months.

Key facts at a glance

Market impact: oil, inflation risk, and equity sensitivity

The price moves were tied directly to perceived supply risk and shipping disruption. Giovanni Staunovo, a commodities analyst at UBS, said oil-market supply tightness would persist and crude prices would remain supported as long as transit through the Strait of Hormuz stays restricted. The reporting also linked higher crude to inflation concerns, with the disruption described as filtering into consumer prices globally. It noted that if Brent breaches $100, central banks could face renewed pressure to delay expected rate cuts, reflecting the role energy plays in headline inflation. In equities, Exxon Mobil and Chevron were mentioned as trading higher during the energy spike, without specific percentage moves provided. For import-dependent economies, elevated crude typically raises input costs, though the reports did not quantify country-level impacts. The overarching takeaway for investors was that the pricing regime has become headline-driven.

Responses and diplomatic activity mentioned

The coverage referred to international coordination efforts as shipping risks rose. It said the UK and France were organizing a 30+ country meeting to establish a defensive escort mission. India was also drawn into the dispute, with New Delhi summoning Iran’s ambassador after Iranian gunboats fired on two Indian-flagged merchant ships during a brief reopening of the strait. Gulf producers were described as facing operational challenges, and the UAE’s Sultan Al Jaber called Iran’s actions and its demand for payment for safe passage a “protection racket” in a post on X. One report said the crisis had blocked nearly 600 million barrels of oil, highlighting the scale of disruption cited in public commentary.

Why the Hormuz choke point keeps setting the tone

The repeated pattern in the reporting is clear: announcements of reopening can quickly be followed by renewed restrictions, and both moves can trigger sharp repricing. That on-off dynamic makes it difficult for physical buyers and ship operators to plan routes, and it magnifies the market’s focus on transit counts and naval incidents. The reports also describe a policy conflict between enforcing a blockade around Iranian-linked flows and preserving freedom of navigation for non-Iranian destinations. In practice, traders responded to the risk that even limited enforcement or selective interdiction can reduce throughput. The return of Brent above $100 on April 22 settlement data shows how fast that risk premium can rebuild.

Conclusion

Brent’s push back above $100 was driven by reported IRGC ship seizures and fresh concerns that transit through the Strait of Hormuz could remain constrained. With shipping data showing tankers turning back and crossings dropping sharply on key days, crude prices stayed highly sensitive to security updates. The next market cues flagged in the coverage include any change in shipping access, further naval incidents, and the direction of ceasefire and negotiation efforts referenced across April.
