Energy markets are once again grappling with heightened geopolitical tensions as the U.S. House of Representatives recently voted to maintain American military presence in Iran. This decision, narrowly passing with a 213-214 vote, sent immediate ripples through the global oil complex, signaling continued uncertainty and a renewed premium for crude benchmarks.
Following the congressional vote, Brent crude for June delivery surged by 4.7%, settling at $101.7 per barrel by 6:44 pm ET on Thursday. West Texas Intermediate (WTI) crude initially spiked over 4% in the immediate aftermath, though it later pared some gains, trading down 1.38% at $93.38 per barrel by evening. The House’s vote mirrors a similar outcome in the Senate just a day prior, largely reflecting partisan divisions with Republicans unified behind continued intervention, citing concerns over Iran’s nuclear capabilities.
While the effort to mandate a withdrawal of U.S. forces failed, some Republican lawmakers are pressing the administration for a clear exit strategy or a defined authorization of force, particularly as the operation approaches the 60-day War Powers Act deadline around May 1. Critics of the ongoing engagement continue to highlight the significant human and financial costs, including at least 13 U.S. service member fatalities, billions in expenditure, and the impact on domestic fuel prices.
Geopolitical Premium Reaffirmed in Crude Markets
The failure of the resolution reignites investor fears of a protracted conflict, potentially leading to sustained high fuel prices and further disruptions to global crude supply. Oil and commodity analysts at Standard Chartered project that an expanded U.S.-imposed counter-blockade could effectively remove an additional 1.5-1.8 million barrels per day (mb/d) of Iranian crude from the market. A significant portion of these barrels typically flow to China, increasing its exposure to the escalating regional instability.
Market structure currently reflects this immediate supply concern. Standard Chartered observes that while front-month Brent contracts have briefly pierced above $120 per barrel during peak volatility, the long-dated portion of the forward curve, or “back-end,” remains anchored and stabilizes in the $68–$70 range. This disparity creates a substantial premium for near-term delivery, with the spread between the first and twelfth month Brent contracts widening considerably. This steep contango primarily indicates that market participants are willing to pay a premium for prompt crude to offset potential disruptions from Middle Eastern supplies.
The primary driver behind this steepness is the ongoing U.S. naval blockade of Iranian ports, which imposes significant constraints on seaborne crude trade. Essentially, the market is actively pricing in a robust “war premium,” which analysts anticipate will gradually dissipate over time, rather than signaling a permanent structural shortage. However, Standard Chartered still forecasts that oil prices will remain $10-20 per barrel higher than pre-conflict levels. This sustained elevation is attributed to factors such as strategic reserve purchases, a growing trend of resource nationalism, precautionary hoarding, and the inherent logistical delays stemming from ongoing supply chain disruptions.
Escalating Risks in Maritime Trade and Shipping Costs
The counter-blockade by the United States also introduces several critical risks for the global energy supply chain. Standard Chartered points to the potential for Iran to retaliate by encouraging Houthi forces to target vessels transiting the Bab al-Mandeb Strait. This vital waterway serves as the southern exit from the Red Sea and is one of only two current export routes for Saudi Arabian crude. While the Houthis currently maintain a ceasefire agreement with the U.S., signed in May 2025, any such attacks would represent a severe escalation, moving beyond existing skirmishes against Israeli positions.
Furthermore, the increased deployment of military assets within the confined Strait of Hormuz significantly elevates the operational risk of an accidental incident. Such an event could quickly lead to broader maritime tensions extending beyond the Gulf region. The heightened risk environment is already impacting shipping economics, with expectations of increased delays, inspections, and potential interdictions. This translates directly into soaring freight and insurance costs for oil and gas traders.
War risk insurance premiums have experienced a dramatic surge, jumping by an astounding 200% to 300%. Premiums specifically for passage through the Persian Gulf have skyrocketed from a mere 0.02%-0.05% of a vessel’s value to an alarming 5%-10%. Consequently, shipping companies are increasingly diverting vessels to longer, safer routes, such as around the Cape of Good Hope, adding considerable transit time and expenses, further impacting the delivered cost of crude.
Natural Gas Markets Show Resilience Amidst Volatility
In stark contrast to the volatile crude oil markets, global natural gas markets have demonstrated remarkable resilience despite the near-term loss of significant Middle Eastern gas supplies. Standard Chartered notes that the disruption to Qatari and UAE liquefied natural gas (LNG) cargoes is largely being offset by robust projected LNG supply growth in 2026, particularly from the United States. Forecasted volumes for delivery over the next couple of years are currently outweighing both existing and anticipated reductions, effectively containing the market shortfall and mitigating severe price reactions.
U.S. natural gas prices, specifically Henry Hub, have cooled considerably. Prices have retreated from above $7.40 per MMBtu when the conflict commenced in late February to a more manageable $2.65 per MMBtu currently. Similarly, European natural gas futures have pulled back sharply from over €60 per MMBtu a month ago, trading at €42.42 per MMBtu on Thursday.
Despite this near-term stability, Standard Chartered identifies potential upward pressure on gas prices during the upcoming summer months. Both European and Asian markets will likely intensify competition for available LNG supplies, as Europe seeks to replenish its comparatively tight storage inventories. Analysts project this demand competition could push European prices potentially over €80 per megawatt hour (MWh). Furthermore, the outlook for U.S. gas remains bullish, driven by increasing domestic demand from data-center power generation, heating, and cooling, alongside robust medium-term export demand for LNG.
