Strategic Shift in Strait of Hormuz Control and Global Energy Security

Following the US-Israeli strikes on Iran on 28 February, a broad consensus has emerged that effective closure of the Strait of Hormuz is not a one-off event. Tehran has demonstrated both the will and ability to impose control on the waterway and strike critical energy infrastructure in neighboring countries. This marks a structural shift in global energy security, embedding a new long-term risk premium into oil prices from the Persian Gulf. Analysts state that the conflict shattered expectations of US control over the strait, removing any ambiguity about Iran's capacity to weaponize it in response to aggression. This vulnerability is now considered a permanent feature of commercial strategy, with experts noting that "you do not walk back from that line very easily."

Impact on Oil Prices and Investment Climate

The outlook represents a significant departure from earlier forecasts of abundant crude supply and low prices. According to Tommy Inglesby of Oliver Wyman, there is "no going back to $30 a barrel," as a new risk premium is embedded in Persian Gulf oil exports. The complexity of capital projects in the region has increased, with the potential for disruptions from drone attacks forcing prolonged shutdowns. Claudio Galimberti of Rystad Energy notes that while below-ground risks in the Middle East are the best, above-ground risks are now the worst, making assets outside the region "marginally more palatable." Structurally higher oil prices, with the back end of the curve between $70 and $80 per barrel, are expected to entice new exploration and production from non-Middle East frontiers.

Diversification Efforts by Major Importers

Energy importers are actively exploring long-term alternatives to reduce dependence on Middle East oil. South Korea, which ships approximately two-thirds of its crude imports via Hormuz, announced visits to Kazakhstan, Oman, and Saudi Arabia to secure supplies. Japan, sourcing over 90% of its crude from the Middle East with more than 70% transiting the strait, has stepped up purchases from the US and will start imports from Mexico. Risk advisors confirm these conversations are happening globally, with a focus on de-risking exposure in the Middle East. South America is deemed a likely big future winner, with major discoveries offshore Brazil and Guyana, and rising appeal for Venezuela. Investments are also flowing into Argentina and western Canada, particularly for heavy crude attractive to Asia.

Challenges in Diversification and Refinery Configuration

Despite the strong desire to reduce risk, rapid diversification poses stiff challenges. Refineries across much of Asia are configured to process medium and heavy sour grades produced in the Middle East. However, Asian refiners have stepped up purchases of light-sweet crude from the US, such as WTI Midland. Japan purchased over 530,000 bpd of US crude for June delivery, exceeding a monthly record of 290,000 bpd in December. Analysts expect Asian buyers to maintain some exposure to Atlantic Basin barrels even if Middle East flows normalize, reinforcing a gradual shift toward non-Dubai linked alternatives and greater flexibility in crude sourcing.

Alternative Export Routes and Remaining Vulnerabilities

Middle East producers are likely to pursue alternative export routes to bypass the Strait of Hormuz. Saudi Arabia and the UAE may add or expand overland pipeline capacity, while Kuwait and Iraq have fewer options, leaving them more exposed. However, Iran has demonstrated its ability to strike infrastructure across the Gulf region, including hitting Saudi Arabia's 7 million bpd East-West pipeline. Experts warn that shifting supply routes merely changes the location of vulnerability, as Iran strategically exploits weaknesses wherever they present themselves. While Persian Gulf states will continue to attract investment and customers, partners will be more skittish, and the Middle East
