The Strait, the Ceasefire, and the Shrinking Premium

Brent Crude Retreats Amid Fragile Ceasefire

• Brent crude prices fell sharply over two consecutive sessions following U.S. President Donald Trump’s announcement of a ceasefire between Israel and Iran last Monday. Although the initial agreement raised hopes for de-escalation, it quickly unravelled as both sides accused each other of violations.
• The benchmark had climbed steadily from below $70 per barrel on June 12, the eve of Israel’s initial strike, peaking at $81.40 on June 23 following U.S. strikes on Iranian nuclear infrastructure. However, that same day, oil prices reversed course. Iran’s retaliation, a restrained missile strike on a U.S. base in Qatar causing minimal damage, was interpreted as a signal of strategic de-escalation. Brent crude subsequently fell to $67 by Tuesday, erasing recent gains and dropping below pre-conflict levels.

Focus on Strait of Hormuz

• Iran’s Supreme National Security Council has been deliberating whether to pursue a partial or complete closure of the Strait of Hormuz, a critical conduit for roughly 20% of the world’s oil and LNG flows. While the Iranian parliament has voiced support, no formal decision has been made.At Cordoba, we maintain the position that full closure remains unlikely.
• Despite periodic threats from Tehran, the strategic and economic risks of closing the Strait are well understood. Regional producers, including Saudi Arabia, the UAE, Kuwait, and Qatar, remain highly dependent on this route. While approximately 2.6 million barrels per day (bpd) of spare pipeline capacity exists, primarily via Saudi Arabia’s East-West pipeline and the UAE’s Fujairah route, most exports still rely on the Hormuz Strait. The U.S. Fifth Fleet continues to patrol the area, underscoring the waterway’s strategic importance.

Markets Stay Calm Amid Falling Risk Premium

• The latest conflict-driven price movement, a 15% swing from low to high, suggests a material re-pricing of the geopolitical risk premium that has long been associated with Middle Eastern conflicts. 

For context:

• 1973 Arab Oil Embargo: Prices nearly quadrupled
• 1979 Iranian Revolution: Spot prices doubled
• 1990 Kuwait Invasion: Brent doubled to $40
• 2003 Gulf War: Prices surged 46%
• Despite direct strikes on nuclear infrastructure and retaliatory attacks, the current episode triggered a calm, calculated market response, not panic. Energy traders are discounting the likelihood of prolonged disruption.

Why Oil Markets Stayed Rational

Several factors are contributing to this shift in behavior:

1) More Data, Better Decisions

• Access to satellite tracking, real-time port activity, and refinery imaging has enabled traders to quantify supply disruptions with far greater accuracy. This has dramatically reduced speculative overreaction.

2) Infrastructure Resilience

• Producers like Saudi Arabia and the UAE have built redundant export infrastructure, pipelines, and strategic storage in Asia and Europe, allowing them to sustain exports during temporary disruptions.

3) Shifting Fundamentals

• OPEC’s share of global supply has declined from over 50% in the 1970s to 33% in 2023, as output from the U.S., Brazil, Canada, Guyana, and China has surged. U.S. shale, in particular, has created a global buffer against regional supply shocks.
• The takeaway is that the oil market’s dependency on Middle East output has structurally declined, loosening the historical link between Gulf politics and price volatility.

Soft Disruption Tactics and Maritime Risk

• While a formal closure of the Strait is unlikely, signs of soft disruption are emerging. A recent collision between two tankers, allegedly caused by electronic jamming, suggests the possibility of a soft closure interfering with logistics without escalating to outright conflict.
• According to Windward, nearly 1,000 ships have experienced disruption since hostilities escalated. CEO Ami Daniel remarked: “There is usually no jamming in the Strait of Hormuz, and now there is a lot,” highlighting the severity of the evolving threat to commercial navigation.

Notable Precedents:

• 2012: Iran threatened closure in response to sanctions (no action followed)
  
• May 2019: Four vessels including two Saudi tankers attacked off UAE coast
  
• 2023–2024: Iran seized three tankers following U.S. seizures of Iran-linked ships

Will There Be a Full Closure of the Strait?

• Following Iran’s recent response to U.S. strikes, a largely symbolic missile attack on a U.S. base in Qatar with minimal impact, the prevailing interpretation is that Tehran aims to signal strength but ultimately intends for de-escalation.
• While tensions remain elevated, we at Cordoba assess that a complete closure of the Strait of Hormuz remains unlikely, though not impossible, based on current geopolitical and economic indicators.

Key factors supporting this assessment include:

• Economic Self-Interest: Iran relies heavily on crude oil exports to China, which accounts for nearly 90% of its oil sales. Disrupting the Strait would jeopardise its revenue streams.
• Lack of Strategic Backing: Major partners, such as China and India, have reportedly urged de-escalation to maintain energy stability, discouraging Tehran from taking extreme action.
• Gulf Interdependencies: Regional economies are deeply interconnected through OPEC+ agreements and shared infrastructure. Disrupting maritime flows would damage Iran’s standing among key allies.
• Diplomatic Off-Ramps: Backchannel communication including potential U.S. mediation remains active, offering an alternative to escalation.
  

Bottom line

• Despite heightened tensions in the Gulf, oil markets have demonstrated notable resilience. 
• At Cordoba, we assess that a full closure of the Strait of Hormuz remains highly unlikely, given Iran’s economic dependencies, diplomatic pressures from key clients like China and India, and the Gulf region’s increasing infrastructural flexibility.
• For investors, this episode highlights a shrinking geopolitical risk premium in oil pricing, driven by enhanced market intelligence and real-time data, diversified global supply beyond OPEC, and strategic infrastructure investments across the Gulf.
• Short-term volatility may persist, particularly in shipping and insurance markets, but systemic disruption remains contained. We’re maintaining a measured exposure to energy assets while closely monitoring geopolitical flashpoints, soft disruption tactics, and evolving maritime risks in the weeks ahead, areas we began exploring in our recent note on ecological constraints and market pricing, where we outlined how fragilities are beginning to feed into sovereign spreads, insurance premia, and broader repricing trends.
• As Brent crude prices spiked and then quickly reversed, markets revealed a growing sensitivity not only to strategic disruption but to underlying structural constraints in energy, labour, and natural resources, as mentioned in previous notes.
• We view this as part of a broader macro trend: growth is increasingly bounded by ecological limits, and energy is no longer just a cyclical input but a core fragility. Geopolitical events like these are early indicators of a world where natural capital, infrastructure resilience, and resource stability will redefine economic advantage and where investors must account not just for short-term shocks but also for long-term systemic stress.
