Strait of Hormuz Under Siege: A Double Shock to Global Energy Markets

Global energy markets are on maximum alert following the military escalation in the Middle East. The outbreak of direct confrontation between the United States and Israel on one side and Iran on the other has effectively paralyzed shipping through the Strait of Hormuz - the vital artery that carries more than 20 percent of the world’s oil and gas supplies - fueling fears of a major supply shock.

How quickly oil tanker traffic resumes normal operations through the strait is now critical. Roughly one-fifth of global oil production and a similar share of liquefied natural gas transit the narrow waterway.

Estimates from JPMorgan suggest that a 25-day halt in tanker traffic would fill storage tanks in producing countries to capacity, forcing them to cut output.

On Monday, in the first trading session since Saturday’s attack, oil prices surged sharply. Brent crude, the international benchmark, jumped as much as 13 percent to trade above $82 a barrel, its highest level since January 2025.

At the same time, insurers announced the cancellation of some policies covering vessels operating in the region. Meanwhile, S&P Global Platts, a leading provider of oil price assessments, suspended bids and offers for Middle Eastern refined product benchmarks that pass through the Strait of Hormuz, citing shipping disruptions linked to the US-Iran conflict. The agency added that it is reviewing its pricing methodology for Middle Eastern crude.

Gas Crisis Deepens

The turmoil has not been limited to oil. Natural gas markets have also been jolted, with European prices jumping more than 30 percent after QatarEnergy announced a suspension of production and exports.

Qatar’s Ministry of Defense said an Iranian drone targeted an onshore gas processing facility in Ras Laffan Industrial City, forcing operations to halt.

The impact is particularly severe for Europe, which relies on Qatar as a strategic alternative to Russian gas. Ole Hvalbye, a commodities analyst at SEB, said disruption to flows through Hormuz, which account for about 20 percent of global LNG supplies, would spark fierce competition between Asian and European buyers for US cargoes, driving prices sharply higher across the Atlantic basin.

The direction of prices now depends largely on how long the conflict persists. Analysts say the base-case scenario hinges on political developments in Tehran, where the international community hopes for either a significant leadership shift or US diplomatic intervention to de-escalate tensions within one to two weeks.

However, if prices remain elevated for a prolonged period, the risk of a renewed global inflation surge looms, placing central banks in a historic bind between curbing inflation and supporting economic growth.

Asia at the Epicenter

Asia - widely regarded as the engine of global growth - now finds itself at the heart of the crisis. The region is the most exposed to the fallout from the Middle East conflict due to its heavy dependence on Gulf oil and gas supplies. This is not merely a trade disruption; it is a direct challenge to energy security across Asian capitals.

Countries such as Japan, South Korea and India rely heavily on Middle Eastern shipping lanes to secure their energy needs. In Japan, around 70 percent of imported oil passes through the Strait of Hormuz, leaving the country highly vulnerable to geopolitical tensions in the corridor. China, despite diversifying its suppliers, remains the largest buyer of Iranian crude and Qatari LNG, making the security of these flows critical to its industrial economy.

Asian governments are now scrambling to reassess their strategic reserves.

If the conflict turns into a prolonged war of attrition, countries such as Japan and South Korea could face an unenviable choice: draw down reserves that may prove difficult to replenish quickly, or accept soaring spot market prices.

With Qatari LNG supplies disrupted, Asia has already entered into intense competition with Europe for US and Australian cargoes. The scramble for alternative supplies is tightening global availability and sharply increasing energy costs across emerging Asian economies.

For India and several Southeast Asian nations, higher prices mean an immediate rise in import bills, placing heavy pressure on balance-of-payments positions and fueling imported inflation that could undermine growth targets for the year.

The strain extends beyond crude oil. Asia’s refineries - the largest in the world - depend heavily on medium and heavy Middle Eastern grades. A sustained disruption in these supplies could force refiners to cut processing rates, leading to shortages of diesel, gasoline and jet fuel within the region itself, with knock-on effects for transportation and logistics.

The current oil supply crisis shows there is underinvestment in oil refining as demand holds resilient, Saudi state-owned Aramco's vice president of market analysis and sustainability, Musaab Al Mulla, said on Tuesday.

Around 3 ⁠million barrels per ⁠day of refining capacity closed between 2020 and 2023, Al Mulla said at the S&P Global Energy Middle East ⁠Petroleum and Gas Conference in London.

"Now we realize if you have those refineries you may have definitely mitigated the impacts of the crisis today," he said.

The war in Iran, attacks on energy infrastructure and ⁠Iran's effective ⁠closure of the Strait of Hormuz followed by a US naval blockade, have removed around 14 million bpd of oil supply from Middle East producers to the global market.

OECD Cuts 2026 Global Growth Forecasts Over Mideast War Fallout

The war in the Middle East has dented economic growth prospects worldwide, with a more severe shock likely if no effective ceasefire is agreed before 2027, the OECD warned Wednesday.

Global economic growth is now forecast to slip to 2.8 percent for 2026 if Gulf exports of oil and gas return to pre-conflict levels in the third quarter, the group of 38 industrialized countries said in its quarterly update.

Previously the OECD had forecast full-year global growth of 2.9 percent.

But if the Middle East war continues into next year, however, global growth could slow to 2.1 percent, the OECD said -- well below the average annual growth of 3.4 percent seen from 2013 to 2019, before the Covid pandemic.

"The longer the disruptions last, the larger the economic and social costs become," the group's chief economist Stefano Scarpetta said in the report.

Many countries would risk falling into recession, he noted, and a drop in investment spending -- "including in energy-intensive AI" -- would likely push up unemployment.

Sustained high prices for energy as well as fertilizer and other key products from hydrocarbon production in the Gulf would weigh especially hard on developing countries that have "higher shares of energy and food in household consumption".

Even if the war sparked by US and Israeli strikes on Iran in late February ends in the coming weeks, the OECD forecast global inflation rising to 4.0 percent this year from 3.4 percent in 2025.

In this "time-limited disruption scenario", the group expects US growth to slow to 2.0 percent this year and 1.8 percent in 2027, after growing 2.1 percent last year.

In the eurozone, where many countries are highly dependent on energy imports, GDP growth will slump to 0.8 percent this year after 1.4 percent last year, assuming a Mideast ceasefire is secured in the coming weeks.

Saudi Non-oil Private Sector Activity Hits 3-month High in May

Saudi Arabia's non-oil private sector expanded at the fastest pace in three months in May as domestic demand improved and supply chains stabilized, while business optimism remained subdued amid conflict in the region, a survey showed on Wednesday.

The seasonally adjusted Riyad Bank Saudi Arabia Purchasing Managers' Index, compiled by S&P Global, rose to 52.8 in May from 51.5 in April. The 50 mark separates growth from contraction, Reuters reported.

Output accelerated at the ⁠fastest pace in ⁠three months after March's downturn following the start of the Iran war, as firms cited normalizing working conditions, revived contracts and stronger local demand.

Export sales fell for a third straight month, hit by shipping disruption, higher freight and fuel costs, geopolitical tensions and stronger competition. The pace of decline eased only modestly from April's survey-record contraction.

However, supply chains improved, with suppliers' delivery times shortening for the first time in three months as ⁠firms relied ⁠more on local vendors. Backlogs of work rose for an 11th consecutive month, albeit moderately.

“Overall, the latest PMI reading supports the expectation that Saudi Arabia’s non-oil economy will continue its upward trend during the remainder of 2026," said Naif Al-Ghaith, Riyad Bank's chief economist.
