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] | |
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 | 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 | 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.
