Middle East oil exports drop at least 60% as Hormuz stays mostly closed, data shows | Reuters

Daily oil exports from the Middle Eastern Gulf, home to top exporter Saudi Arabia and other major producers, have dropped by at least 60% in the week to March 15 compared to February due to disruptions and output cuts amid the ​U.S.-Iran war, according to shipping data and Reuters calculations.

The effective closure of the Strait of Hormuz, ​normally used to transport about a fifth of the world's oil supply, has forced ⁠exporters to cancel shipments and shut production at oilfields, creating the world's biggest ever supply disruption. Crude oil ​prices have surged to the highest in four years and those of some fuels to record highs.

Crude, condensate ​and refined fuels exports from eight Middle Eastern countries - Saudi Arabia, Kuwait, Iran, Iraq, Oman, Qatar, Bahrain, and the United Arab Emirates - in the week to March 15 averaged 9.71 million barrels per day, data from Kpler showed, down 61% from ​25.13 million bpd in February.

Data from Vortexa shows an even more dramatic drop, with exports from the eight ​countries last week reaching 7.5 million bpd, down 71% from February's 26.1 million bpd.

Prior to the war, the eight ‌countries ⁠accounted for 36% or global seaborne oil exports of 70.43 million bpd, according to Kpler.

The actual exports could be even lower as some volumes go into floating storage but not leaving the Gulf.

"Floating storage of Middle Eastern crude has surpassed 50 million barrels this week, up from pre-war levels of around 10 million barrels," Kpler ​analyst Johannes Rauball said.

Loadings ​from the UAE's Fujairah ⁠port have been disrupted in the past few days due to drone attacks.

Oil flows that are continuing include exports from Saudi Arabia's Red Sea port of Yanbu, Iran's exports, Oman's exports ​and the UAE's flows from Fujairah.

Total oil output cuts from Middle East producers ​have risen as ⁠the countries run out of storage and traffic through Hormuz remains a fraction of normal levels.

Oil output in the United Arab Emirates, which pumped about 3.4 million bpd before the conflict, is down by more than half, Reuters reported ⁠on ​Monday. Saudi Arabia has cut production by 20%, and Iraq by ​some 70%. Total crude oil output cuts in the Middle East now stand at 7-10 million bpd, according to analysts' estimates.

Mideast Stocks: Most Gulf equities decline as #Iran conflict fuels regional market uncertainty

Mideast Stocks: Most Gulf equities decline as Iran conflict fuels regional market uncertainty

Most Gulf stock markets ended lower on Monday, led by losses in Dubai as the U.S. and Israel's war with Iran weighed ​on investor sentiment. Over the weekend, ⁠Trump threatened further strikes on Iran's Kharg Island — which accounts for roughly 90% of the country's oil exports — ‌after earlier attacks on military targets prompted a defiant response from Tehran and raised the prospect of further retaliation.

Shortly after the attacks on ​Kharg, Iranian drones struck a major oil terminal in Fujairah, United Arab Emirates. Although oil loading operations at Fujairah have resumed, four sources said ​it was ​unclear whether activity has fully returned to normal.

Dubai's main share index declined 2.5%, dragged down by a 4.9% slide in blue-chip developer Emaar Properties and a 1.7% retreat in top lender Emirates NBD .

Since the conflict began, ⁠the index has shed more than 18%, bringing its valuation down to 843.25 billion dirhams ($229.61 billion). Citigroup is keeping most branches and offices in the UAE closed until further notice after temporarily closing them last week, the bank said on Monday, the latest sign of the impact on the industry of the Iran war.

Gulf equities are showing a growing divergence as the regional ​conflict drives a swift ‌repricing of risk ⁠amid persistently high trading volumes, ⁠said Ahmad Assiri, research strategist at Pepperstone.

"While the overarching narrative remains anchored by energy fundamentals, the price action reveals a market at ​a crossroads where investor conviction is being tested by shifting security dynamics in critical maritime ‌corridors."

In Abu Dhabi, the index lost 0.2%, hit by a 3.5% drop in ⁠Aldar Properties.

Meanwhile, the bourse's market capitalization has shrunk to $771.9 billion, down nearly $77.2 billion from pre-conflict levels.

Earlier this month, the Dubai and Abu Dhabi exchanges introduced a temporary 5% daily downside limit on listed securities and suspended trading on March 2 and March 3, as part of broader measures to curb volatility and maintain orderly market conditions.

Saudi Arabia's benchmark index gained 0.6%, led by a 1.1% rise in the country's biggest lender by assets Saudi National Bank .

According to Assiri, Saudi Arabia's TASI stands out as the region's clearest dip-buying story, with equities showing notable resilience by testing the key 11,000 level before easing slightly ahead of the Eid holiday. The trading pause could offer a timely breather as global ‌efforts intensify to secure energy routes through the Strait of Hormuz.

However, oil major ⁠Saudi Aramco eased 0.2%. Oil prices were mixed, with benchmark Brent crude slightly higher ​and U.S. crude prices down amid attacks on Gulf oil production and Trump's call for global efforts to secure the Strait of Hormuz. The Qatari index fell 1.2%, with Qatar National Bank , the Gulf's biggest lender by assets, losing 2%.

Oman's index was down ​0.7% and Bahrain's dropped ‌1.8%.

Boursa Kuwait lost 0.4%.

Outside the Gulf, Egypt's blue-chip index slipped 1.6%, as most of its ⁠constituents were in the negative territory.
