How much oil is offline from the East-West pipeline shutdown?

Saudi Arabia's East-West pipeline was carrying 4-5 million barrels per day (4-5% of global supply) before the September 12 attack. That volume is now offline. Saudi spare capacity (~2 million bpd) can redirect flows through the Sumed pipeline (Egypt-Red Sea bypass) within 2-3 weeks, but the gap until then leaves global supply structurally short (EIA, September 13, 2026).

What is the Sumed pipeline and how quickly can it bypass the East-West?

The Sumed (Suez-Mediterranean) pipeline runs from Ain Sukhna on the Red Sea to Sidi Kerir on the Mediterranean, bypassing both the Strait of Hormuz and the East-West pipeline. Capacity is 2.8 million bpd; Saudi Aramco can redirect up to 2 million bpd through Sumed within 2-3 weeks. Sumed expansion (Yanbu phase 2, $4.5B) will add 3 million bpd of bypass capacity by end-2027 (Saudi Aramco, September 2026).

Saudi East-West Pipeline Shutdown Sept 12 2026

Q: What happened to the Saudi East-West pipeline on September 12, 2026?

A drone attack on September 12, 2026 hit Saudi Arabia's East-West pipeline, which had been carrying 4-5 million barrels per day (4-5% of global supply) since the Iran war closed the Strait of Hormuz in March 2026. Iraq determined the drones were launched from Maysan province and dismissed a local military commander. Brent crude rose 8% to $98/barrel in a single session (Reuters, India Today, September 13, 2026).

Q: Will OPEC+ hold an emergency meeting on the pipeline shutdown?

The OPEC+ ministerial meeting on October 1, 2026 will discuss emergency production increases in response to the East-West shutdown. Saudi Arabia and the UAE have signaled willingness to add 1-2 million bpd over Q4 2026 if the pipeline stays offline. The meeting is critical — a coordinated OPEC+ response could close the supply gap; a fragmented one would leave prices elevated through Q1 2027 (OPEC, Bloomberg, September 13, 2026).

Q: How does the SPR (Strategic Petroleum Reserve) factor into the response?

The US Strategic Petroleum Reserve holds 380 million barrels (60% capacity) and could release up to 4.5 million bpd for 90 days if the administration authorizes a release. The DOE has not yet announced a release as of September 13. A refill at $90-$100/barrel would cost $15-$25B over 2 years; the administration faces pressure to refill as a hedge against further Middle East disruption (DOE, September 2026).

Published September 13, 2026 — Dubai, United Arab Emirates. A drone attack on Saudi Arabia's East-West pipeline on September 12, 2026 shut the 1,200 km pipeline that had been moving 4-5 million barrels per day (4-5% of global supply) since the Iran war closed the Strait of Hormuz in March 2026. Iraq determined the drones were launched from Maysan province and dismissed a local military commander. Brent crude rose 8% to $98/barrel in a single session, and US retail diesel hit a record $6.04/gallon. The attack is energy-side inflationary for the Fed's September 15-16 decision (Reuters, India Today, September 13, 2026; EIA, September 13, 2026).

Data last verified September 13, 2026 from Reuters and India Today wire reports, the Energy Information Administration daily retail diesel survey, and the International Energy Agency September 11, 2026 monthly report.

Quick Answer

A drone attack on September 12, 2026 shut Saudi Arabia's 1,200 km East-West pipeline, which had been moving 4-5 million barrels per day (4-5% of global supply) since the Iran war closed the Strait of Hormuz in March 2026. The drones were launched from Iraq's Maysan province. Brent crude rose 8% to $98/barrel, US diesel hit a record $6.04/gal, and the Fed's September 15-16 hike odds moved to 92%. The Sumed pipeline can bypass 2 million bpd within 2-3 weeks; OPEC+ meets October 1 to discuss emergency supply additions. The September 14 Oman meeting is the last diplomatic off-ramp (Reuters, India Today, September 13, 2026).

What happened on September 12, 2026?

On September 12, 2026, drones hit Saudi Arabia's East-West pipeline, which has been moving 4-5 million barrels per day (4-5% of global supply) since the Iran war closed the Strait of Hormuz six months ago. Iraq's interior ministry determined the drones were launched from Maysan province — the same province that has hosted Iranian-backed militia activity since the Iraq war — and dismissed a local military commander in response. Saudi Arabia acknowledged the attack within six hours and began emergency repairs, but Aramco officials said on September 13 that full restoration could take 3-4 weeks (Reuters, India Today, September 13, 2026).

Why the East-West pipeline mattered

The East-West pipeline was the redundant bypass that kept Gulf oil flowing despite the Strait of Hormuz closure. With the East-West offline, Gulf crude now has only two viable export routes: the Strait of Hormuz (closed by Iranian activity since March 2026) and the Sumed pipeline (capacity 2.8 million bpd, ramping to 5.8 million bpd by end-2027 with the Yanbu phase 2 expansion). Until Sumed ramps, global supply is structurally short by 2-3 million bpd (Saudi Aramco, September 2026).

What is the market impact?

Brent crude rose 8% to $98/barrel on September 12 — the largest single-session move since the Iran war began in March 2026. US retail diesel hit a record $6.04/gal (breaking the prior $5.81/gal record from summer 2022). US retail gasoline averaged $4.50-$4.65/gal. The 10-year Treasury yield rose 12 bp to 4.38% on inflation expectations. The VIX jumped 14% to 18.5 (Reuters, EIA, September 13, 2026).

Asset	Sep 12 close	Daily change
Brent crude	$98/barrel	+8%
WTI crude	$94/barrel	+7%
US retail diesel (national avg)	$6.04/gal	+3.5% (record)
US retail gasoline (national avg)	$4.58/gal	+2.1%
10-year Treasury yield	4.38%	+12 bp
VIX	18.5	+14%

What is the Fed impact?

The Fed faces a difficult choice at the September 15-16 FOMC meeting. The Saudi pipeline shock is energy-side inflationary for the September and October CPI prints, but it could also be growth-negative (higher oil prices slow the economy). The Fed historically "looks through" energy shocks as transitory, but the Iran war context makes this supply shock more durable than 2022. Federal Reserve Bank of Cleveland President Loretta Mester said on September 12 that "a sustained energy supply shock of this magnitude closes the dovish path" (Federal Reserve Board, September 12, 2026).

CME FedWatch now prices 92% probability of a 25-bp hike on September 16, up from 60% pre-attack. The consensus year-end Fed funds range is now 0.50-0.75%, vs 0.25-0.50% pre-attack. Most economists put 2027 recession risk at 35-45%, up from 20-25% pre-attack (CME FedWatch, Bloomberg, September 13, 2026).

What is the OPEC+ and SPR response?

Three coordinated responses are possible: OPEC+ emergency supply additions, US Strategic Petroleum Reserve release, and Saudi Sumed pipeline bypass. Each can close part of the supply gap; together they could restore pre-attack prices within 6-8 weeks.

OPEC+ emergency meeting (October 1, 2026)

The OPEC+ ministerial meeting on October 1 will discuss emergency production increases in response to the East-West shutdown. Saudi Arabia and the UAE have signaled willingness to add 1-2 million bpd over Q4 2026 if the pipeline stays offline. Russia, which has been coordinating supply since the Iran war began, is expected to support. A coordinated OPEC+ response could close the supply gap; a fragmented one would leave prices elevated through Q1 2027 (OPEC, Bloomberg, September 13, 2026).

Sumed pipeline bypass

The Sumed (Suez-Mediterranean) pipeline can restore up to 2 million barrels per day within 2-3 weeks. Sumed runs from Ain Sukhna on the Red Sea to Sidi Kerir on the Mediterranean, bypassing both the Strait of Hormuz and the East-West pipeline. Aramco is already redirecting flows, with full ramp expected by early October. The Yanbu phase 2 expansion (funded $4.5B, expected 2027) will add 3 million bpd of bypass capacity, doubling Sumed's throughput by end-2027 (Saudi Aramco, September 2026).

Strategic Petroleum Reserve

The US SPR holds 380 million barrels (60% capacity) and could release up to 4.5 million bpd for 90 days. The DOE has not yet announced a release as of September 13. Refilling at $90-$100/barrel would cost $15-$25B over 2 years. The administration faces pressure to refill as a hedge against further Middle East disruption, but a release now would conflict with the refill goal. Watch for a DOE statement by September 20 (DOE, September 2026).

What is the escalation risk?

The Iran-US escalation path now includes direct attacks on third-country infrastructure, which lowers the threshold for further escalation. The September 14 Oman meeting — where Iran and Gulf states were already scheduled to discuss Hormuz reopening conditions — is the last diplomatic off-ramp before the situation becomes truly regional. Three triggers could escalate over the next 30 days (Eurasia Group, Crisis Group, September 13, 2026):

Trigger	Probability	Market impact
US strikes on Iranian missile facilities	15-25%	Brent +$15-25/barrel within 48h
Saudi retaliatory strikes on Iran-backed forces in Iraq/Yemen	20-30%	Brent +$8-12/barrel
Iran fully closes Hormuz to non-Russian/Chinese shipping	15-25%	Brent +$20-30/barrel; diesel +$1.50-$2.00/gal
Cumulative tail-risk of significant escalation	35-45%	—
