Impact Assessment of US/Israel-Iran Conflict

US / Israel–Iran War · Crude Market Update
Last Updated: 18 Mar 2026

Market / War Update
  • Israeli strike kills top Iranian official — Israel announced the elimination of Iran's national security chief Ali Larijani, Iran's de-facto leader, in a targeted airstrike in Tehran. The kill was confirmed by the Israeli Defence Minister, marking the most significant leadership strike of the entire conflict.
  • Iran firesfresh missile salvo at Israel — Iran launched cluster missiles and fresh barrages hitting central Israel with multiple impact sites reported, injuring at least one person. Simultaneous drone and rocket attacks targeted the US Embassy in Baghdad, causing explosions and injuries to personnel.
  • Iran escalates on Gulf & shipping — Iranian drones struck the UAE's Shah gas field (set ablaze) and the Fujairah Oil Industry Zone. Another tanker was hit near the Strait of Hormuz. Saudi Arabia intercepted over a dozen drones amid simultaneous attacks targeting Kuwait and Bahrain.
  • Israeli and US strikes intensify — The Israeli Air Force conducted over 200 additional strikes on Iranian command centres, air defences, and infrastructure across western and central Iran in the past 24 hours. The US is deploying further military assets to the Middle East.

The Trump administration is using the current 20–30 day supply buffer window to assess a clearer long-term strategic direction. Until a definitive war or de-escalation plan emerges, crude prices will remain highly event-driven and volatile.

SPR / IEA

IEA member nations have agreed to a coordinated release of 400 mln bbl — the largest emergency SPR release since the IEA was founded after the 1973 Oil Crisis. The US, under the Trump administration, is contributing 172 mln bbl structured as loans to companies with repayment including a premium.

Deliveries are expected to begin reaching the market by the end of next week and will continue over approximately 120 days. The first batch of 86 mln bbl has already been opened for bidding. Japan will release 80 mln bbl beginning 16th Mar'26.

Key Supply Infrastructure

GCC Bypass Pipelines Running Near Capacity — But Shah Gas Field Ablaze and Fujairah Zone Struck

  • Saudi Arabia's East–West Pipeline and the UAE's ADCOP are fully operational, providing combined bypass capacity of approximately 6.5–7.0 MBpd above pre-conflict export levels. Both lines are running at or near maximum utilisation as of mid-Mar 2026.
  • Of approximately 15 MBpd of crude transiting the Strait of Hormuz in OND'25, combined SPR releases and bypass pipeline capacity can offset roughly two-thirds — or slightly more — for the next 20 to 30 days, providing the Trump administration a window to assess strategic direction.
  • New strikes directly threaten this buffer — Iranian drones struck the UAE's Shah gas field (currently ablaze) and the Fujairah Oil Industry Zone on Mar 17. A tanker was also hit near the Strait of Hormuz. Saudi Arabia intercepted over a dozen drones; Kuwait and Bahrain sustained additional attacks. These represent the first direct strikes on GCC energy export infrastructure since the conflict began.
Supply & Demand Analysis

War Scenarios Point to Global Supply Deficit of 1.35–1.90 MBpd in 2026; AMJ Quarter Most Severe

Pre-war, global supply and demand were near-balanced with a modest surplus of +0.55 MBpd projected for 2026. Both conflict scenarios introduce significant supply deficits driven by Strait of Hormuz disruptions and impacts on Iraq and Kuwait crude production.

  • Scenario 1 (Preferred): Exchange of attacks between US/Israel and Iran continuing, leading to severe/significant/complete disruptions of crude oil and its products trade through the Strait of Hormuz, severely impacting Iraq's and Kuwait's crude oil production over the next 3 to 6 months. Full-year 2026 deficit: −1.90 MBpd. AMJ quarter most acute at −4.50 MBpd.
  • Scenario 2 (Alternate): Partial disruptions of crude oil trade through the Strait of Hormuz, with Iran not targeting ships and oil tankers moving toward China, India, and select Asian nations outside the Western alliance. Full-year 2026 deficit: −1.35 MBpd. Balance returns to flat by OND '26.
Economic Updates
  • The US Dollar Index declined during the session, falling from 99.71 to 99.57, marking a 0.14% day-to-day decrease, though it remains around 0.75% higher on a weekly basis. The decline was largely driven by a risk-on shift in market sentiment, as US equities moved higher during the session, reducing short-term demand for the dollar.
  • In addition, profit-taking after the recent rally in the greenback where DXY touched 10 month high, contributed to the pullback. Despite the short-term decline, the broader trend in the dollar has remained supported by greater clarity around the U.S. interest-rate outlook and heightened geopolitical tensions.
Price Outlook

Brent Expected to Trade 90–120 USD/bbl

Brent Crude 1M Futures are expected to trade in a range of 90 USD/bbl to 120 USD/bbl over the coming 1 to 2 weeks. The coordinated SPR release and GCC bypass capacity provide a meaningful supply cushion that limits sustained upside beyond these levels.

📦 Price Impact

US deliveries flow into the market over a 120-day window. Combined with GCC bypass pipeline capacity, the SPR mechanism limits sustained price upside. The loan structure (with repayment premium) signals a temporary buffer — markets will watch replenishment dynamics once the conflict stabilises.

Key Supply Infrastructure
GCC Bypass Pipelines Running Near Capacity — But Shah Gas Field Ablaze and Fujairah Zone Struck
Saudi Arabia's East–West Pipeline and the UAE's ADCOP are fully operational, providing combined bypass capacity of approximately 6.5–7.0 MBpd above pre-conflict export levels. Both lines are running at or near maximum utilisation as of mid-Mar 2026. Of approximately 15 MBpd of crude transiting the Strait of Hormuz in OND'25, combined SPR releases and bypass pipeline capacity can offset roughly two-thirds — or slightly more — for the next 20 to 30 days, providing the Trump administration a window to assess strategic direction. New strikes directly threaten this buffer — Iranian drones struck the UAE's Shah gas field (currently ablaze) and the Fujairah Oil Industry Zone on Mar 17. A tanker was also hit near the Strait of Hormuz. Saudi Arabia intercepted over a dozen drones; Kuwait and Bahrain sustained additional attacks. These represent the first direct strikes on GCC energy export infrastructure since the conflict began.
⚠ Infrastructure Risk — Critical

The strikes on Shah gas field and Fujairah represent a direct Iranian attempt to degrade the very bypass capacity markets are relying on. Any confirmed damage to the East–West Pipeline or ADCOP would significantly narrow the 20–30 day supply offset window and push prices sharply toward — or potentially beyond — the $110/bbl ceiling.

Price Outlook
Brent Expected to Trade $90–$120/bbl; Larijani Killing and GCC Infrastructure Strikes Add Severe Upside Risk
Brent Crude 1M Futures are expected to trade in a range of $90/bbl to $120/bbl over the coming 1 to 2 weeks. The coordinated SPR release and GCC bypass capacity provide a meaningful supply cushion that limits sustained upside beyond this band — however, today's strikes on GCC energy infrastructure and the Larijani assassination introduce the most significant upside price risk since the conflict began.

$90 floor $105 base $120 ceiling
$90–$105 · Supply buffers holding
$105–$120 · Elevated war premium
⚠ Key Price Drivers to Watch

Movement toward — or beyond — $120/bbl is likely if: (1) Iran retaliates massively for the Larijani killing with strikes on GCC pipeline or port infrastructure, (2) confirmed damage to the Shah gas field or Fujairah zone materially disrupts UAE export capacity, (3) further tanker strikes escalate Strait of Hormuz risk, or (4) SPR drawdown confirmation is delayed. Conversely, any credible ceasefire signal or de-escalation would pull prices sharply back toward the $90–$95/bbl floor.

Market / War Update
Conflict Enters Week Three — Iran Launches Major Ballistic Missiles on Israel
The Iran–Israel–US conflict entered its third week with significant intensification. Key developments: Iran's largest missile barrage of the war struck Israel over March 13–14, as Hezbollah simultaneously launched approximately 97 rocket and missile attack waves — the highest single-day total since the conflict began. Israel responded with strikes on Hezbollah infrastructure in southern Beirut and Lebanon and is preparing a ground expansion south of the Litani River. US deepened regional involvement2,500 Marines are deploying to the theatre as the US works to secure freedom of navigation through the Strait of Hormuz. Oil prices briefly exceeded $100/bbl on escalation news. Humanitarian toll is mounting: over 850 deaths in Lebanon, continued casualties in Gaza, and rising fears of broader regional destabilisation affecting global trade and shipping routes. The Trump administration is using the current 20–30 day supply buffer window to assess a clearer long-term strategic direction. Until a definitive war or de-escalation plan emerges, crude prices will remain highly event-driven and volatile.
Key Supply Infrastructure
GCC Bypass Pipelines Add 6.5–7.0 MBpd; Two-Thirds of Hormuz Flow Can Be Offset for 20–30 Days
Saudi Arabia's East–West Pipeline and the UAE's ADCOP are now fully operational and ramped up, providing a combined bypass capacity of approximately 6.5–7.0 MBpd above pre-conflict export levels. Both lines are running at or near maximum utilisation as of end-Mar 2026. Of approximately 15 MBpd of crude (excluding condensates and other liquids) transiting the Strait of Hormuz in OND'25, combined SPR releases and bypass pipeline capacity can offset roughly two-thirds — or slightly more — for the next 20 to 30 days, giving the Trump administration time to assess longer-term strategic direction before the buffer is exhausted.

The vertical lines show the starting point of wars, and the post-war price movement is highlighted with red ellipses, which are tabulated in the first table.
Observations:
  • Prices witnessed high volatility a few months before the start dates of wars and this continued for the next couple of months.
  • The trend prior to war continued even after the start of war for a maximum period of 2 to 3 months, and then witnessed a notable trend reversal for the medium to long term.
  • The mean and median magnitude of moves are 13.5% and 10.6%, respectively. Measured from the close of the prior day to the start of war, adding half a standard deviation to the mean translates to a range between USD 3345 and USD 3688, which can be attained in 4 to 6 weeks from the war start date, i.e. 28-Feb’26.
