A Short History of Market-Moving Middle East Conflicts

March 4, 2026

Every generation of investors learns the same lesson the hard way: Middle East conflicts spike oil and spook stocks, and then markets do whatever they want. Monday’s price action was a textbook example. US and Israeli strikes on Iran sent oil up 13%, stocks down, and bonds up in the overnight session. By the close? The S&P 500 finished with a gain of less than 0.1%, oil had given back more than half its surge, and Treasuries reversed.[13][18] It’s a pattern that has repeated, with only one true exception, for over fifty years.

Here’s the scorecard.*

#	Conflict	Date	Oil Move	S&P Move	Resolution Speed
1	Yom Kippur War & Arab Oil Embargo	Oct 1973–Mar 1974	Oil nearly quadrupled, from ~2.90to2.90 to 2.90to11.65/bbl [7]	S&P 500 fell 40% over the following year [13]	Sustained bear market — the only true outlier
2	Iranian Revolution	1978–1979	Oil roughly doubled to ~$39.50/bbl [24]	Down 6.2% over one month; recovered 5.3% over 12 months [45]	S&P didn’t truly bottom until mid-1982 (–25%), compounded by monetary tightening [45]
3	Iran–Iraq War Outbreak	Sept 1980	Oil rose to ~40/bblfrom 40/bbl from ~40/bblfrom 35 [40]	Down 15% initially; S&P finished 1980 up ~26% [24]	Weeks — trade routes adjusted
4	Gulf War (Iraq invades Kuwait)	Aug 1990–Feb 1991	Oil doubled, from 17to17 to 17to36/bbl [7]	S&P fell 18%; took 260 days to recover [54]	On Jan 17 1991 (Desert Storm launch): oil crashed 33%, S&P jumped 3.7% [19]. S&P up 29% by year-end [40]
5	Iraq War	Mar 2003	Oil fell from pre-war highs near 37toavg37 to avg 37toavg30/bbl in 2003 [1]	S&P up 13.8% in 3 months, 18.6% in 6 months [13]	Immediate — classic “sell the rumor, buy the news”
6	Israel–Hezbollah War	Jul–Aug 2006	Oil hit record $79/bbl [1]	Brief 5% S&P correction [24]	Weeks
7	Arab Spring & Libya	Feb–Oct 2011	Oil rose from 92 to 92 to 92 to120/bbl [19]	S&P fell 21.6% peak-to-trough (mostly Euro debt crisis/US downgrade) [1]	Months — but driven by non-ME factors
8	ISIS Surge in Iraq	Jun–Dec 2014	Brent spiked to 115 on Jun 19[2],then∗∗collapsed 4115 on Jun 19, then collapsed 44% by Dec on supply glut [9][15]	S&P max drawdown –7%; finished 2014 up +11% [50]	Supply/demand overwhelmed geopolitics
9	Saudi Aramco Drone Attack	Sept 14, 2019	Oil jumped ~14%, from 60to60 to 60to69/bbl [34]	S&P finished the day roughly flat [1]	Two weeks — Aramco fully restored production [1]
10	Soleimani Assassination	Jan 3, 2020	WTI up 3.1% to $63.05 [34]	S&P down 0.7% [1]	Days — both sides de-escalated
11	Israel–Hamas War	Oct 7, 2023	WTI up 3.59to3.59 to 3.59to86.38; Brent up 3.57to3.57 to 3.57to88.15 [38]	S&P gained 0.63% on first trading day [5]	Immediate for markets
12	Iran–Israel Direct Strikes	Apr 13–19, 2024	Brent briefly touched ~$90; quickly faded	S&P futures up 0.3% [49]	Immediate — attack telegraphed, 99% intercepted
13	Israel–Iran War (Jun 2025)	Jun 13–24, 2025	Brent jumped 7.6% [54]	S&P day-one loss ~1% [54]	Oil retreated to near pre-conflict levels after Jun 24 ceasefire
14	US–Israel Strikes on Iran (“Operation Epic Fury”)	Feb 28, 2026 – ongoing	Oil up 13% intraday; Brent settled +6.7% at 77.74;WTI+6.377.74; WTI +6.3% at 77.74;WTI+6.371.23 [18][19]	S&P finished with a gain of less than 0.1%; Dow dipped 0.1% [13]. Nikkei –1.35%, STOXX 600 –1.76% [18]	Strait of Hormuz effectively closed; situation fluid

What the Data Actually Says

Across all 14 conflicts, the averages tell a consistent story. Total S&P 500 drawdowns around Middle East geopolitical events have averaged 4.6% (median 2.9%) over an average of about 19 days (median 8 days).[54] Geopolitical-driven S&P 500 selloffs are typically modest at around 3%, and equities typically recover rapidly once the conflict has stabilized.[49] Since 1967, except for the Yom Kippur War in 1973, none of the 11 major military conflicts involving Israel have had a lasting impact on oil prices.[51]

The only true exception, the 1973 embargo, involved a sustained physical withholding of oil supply for months, not a military strike. The Gulf War (1990) produced the second-worst equity drawdown at 18%, with the S&P 500 taking 260 days to recover,[54] but even that was reversed by year-end, with the S&P up 29% from the start of Operation Desert Shield.[40] In both cases, it was the broader economic environment, recession dynamics and monetary policy, that determined whether the oil shock became a lasting equity decline, not the headline violence itself.[54]

The Pattern Since the 1970s: Buy the Rumor, Sell the News

From the 2003 Iraq War onward, every single Middle East conflict has followed the same playbook for equity investors: futures plunge overnight on the headlines, oil spikes, safe havens catch a bid, and then the session reverses as traders assess the disruption as temporary or contained. The Iraq War saw the S&P gain 13.8% in three months after bombing began.[13] The Aramco drone attack moved oil 14% but the S&P finished flat.[34][1] Monday’s action, oil up 13% at the highs, S&P futures sharply lower overnight, and then a full reversal to a fractional S&P gain by the close[13][18], fit the template almost perfectly.

That said, the Strait of Hormuz is effectively closed to tanker traffic as of this writing, and the situation remains fluid.[18] If history rhymes, the market is betting this resolves like every post-1973 conflict: quickly. If it doesn’t, if physical oil supply is durably impaired, then the 1973 playbook, not the 2019 one, becomes the relevant comparison. The market has chosen its side. It almost always does. It’s also been right almost every time, except when it wasn’t.
