The Iran conflict is no longer a tail risk. It is the market's main event. Joint U.S.-Israeli airstrikes began on February 28, 2026, targeting Iranian leadership and military infrastructure, including the killing of Supreme Leader Ali Khamenei. Iran hit back fast and hard. Retaliatory missile and drone strikes targeted U.S. embassies, military installations, and oil infrastructure across the Middle East, including vessels in the Strait of Hormuz.
Markets got the initial shock. What they do not yet have is the full picture. Three questions are still open. Until they close, volatility is the baseline.
Question 1: Will Iran directly target U.S. military assets at scale?
This is the trip wire. Everything else in the conflict has a precedent. Direct, large-scale Iranian strikes on U.S. military assets do not.
Direct U.S.-Israeli strikes on Iran mark a shift from deterrence to open warfare. With U.S. intent explicit, the scale and targets of Iranian retaliation now determine escalation and downside risk.
Iran has already struck regionally. Missile and drone strikes have hit UAE territory, including the Jebel Ali port and Abu Dhabi port infrastructure, as well as targets in Saudi Arabia and Bahrain. That is significant. But it is not the same as a direct, sustained assault on U.S. forces. The latter triggers a different American military response and a full-scale risk-off move in markets.
Equities may see a sharp but potentially short-lived sell-off in that scenario, consistent with historical experience from targeted U.S. military strikes. Tightening financial conditions would disproportionately hit economies most reliant on capital markets.
The difference between a regional spat and a war that traps every major equity index sits almost entirely on this question. If Iran crosses that line, watch for a flight out of equities and into gold, U.S. Treasuries, and the dollar. This is not a scenario to brush off. Iran pre-positioned warheads near regional borders before the conflict began. The broader escalation was planned, not improvised.
What the market is pricing
Right now, markets are betting on a contained exchange. In June 2025, when Israel struck Iranian nuclear sites, equities sold off sharply at the open, then recovered once it became clear the Strait of Hormuz was not disrupted. That playbook is what traders are referencing. But this conflict is structurally different in scope and intent. The June 2025 war lasted 12 days. This one has already outlasted it.
Question 2: How durable is the oil supply disruption?
Oil did not just spike and fade. The conflict has already suspended about a fifth of global crude oil and natural gas supply as Tehran targets ships in the Strait of Hormuz. That is not a headline risk. That is a physical supply problem.
The Strait facilitates 20 million barrels per day, approximately 20% of global supply. Current Brent pricing embeds a $10 to $15 risk premium, with forecasts suggesting a surge to $130 per barrel if maritime flows are fully obstructed.
The pipeline alternatives are not enough. The combined capacity of Saudi Arabia's East-West Pipeline and the UAE's ADCOP totals approximately 8.3 to 8.8 million barrels per day. Saudi Arabia and the UAE have the barrels. They cannot move them without secure transit routes.
LNG markets are getting hit separately. Qatar declared force majeure on its gas exports after Iranian drone attacks, and it may take at least a month to return to normal production levels. Qatar supplies 20% of global liquefied natural gas.
European gas benchmark prices surged nearly 50% on March 2, the biggest daily move in more than four years. Energy import-dependent economies are absorbing that first. But if prices stay elevated, the inflation impulse spreads.
The duration question
A prolonged conflict with significant disruptions in the Strait of Hormuz could see oil reaching $100 per barrel, but most analysts expect it to settle back around $70 by end of 2026 if the market adapts. The base case assumes partial resolution within four to six weeks. The risk case does not.
Protracted oil-supply disruptions could lift gas prices, fan consumer inflation, and slow household consumption. A sustained energy-supply shock could also box in the Fed, increasing the odds of smaller rate moves or a pause as officials weigh inflation against growth.

Cash flow models for oil-sensitive companies need to be stress-tested at $90, $100, and $130 scenarios right now. Not as doomsday exercises. As normal risk management.
Question 3: Does Israel strike Iranian nuclear infrastructure next?
This is the tail risk that markets have not fully priced. Israel has already struck a covert Iranian nuclear weapons site outside Tehran as oil rallied and risk premiums snapped back into markets. That was not the end of the story. It was an escalation node.
The U.S. framing of this conflict matters. President Trump confirmed that U.S. forces are conducting major combat operations alongside Israel, with the campaign explicitly aimed at degrading Iran's missile capabilities and preventing nuclear reconstitution.
"Preventing nuclear reconstitution" is the key phrase. It sets the conditions for continued strikes on nuclear infrastructure. If that happens at scale, the market shock would be categorically different. Full-spectrum nuclear targeting would trigger the most extreme risk-off move of the conflict. Defense and energy stocks would spike. Broad equity indices would fall hard and fast.
During previous geopolitical events that led to an oil shock, global equities have seen an average decline of 3%, followed by a recovery within 40 days on average. That average is distorted by the 1990 Gulf War, which produced a nearly 18% drawdown over six months. A nuclear infrastructure escalation scenario is closer to the 1990 template than to any recent Middle East skirmish. The diversification argument for holding defensive stocks and energy exposure just got stronger.
The asymmetric positioning opportunity
This is a headline-driven tape with asymmetric tails. Energy equities and services names tend to over-earn in short spikes and underperform if the premium fades quickly. That is the structural opportunity.
Equity markets have consistently underpriced Middle East conflict tail risks until an actual supply disruption hits. The disruption has now hit. Investors who were already positioned in energy and safe-haven assets are sitting on gains. Those who were not are chasing.
The playbook for navigating this kind of market sentiment shift is covered in the Stoxcraft piece on why this selloff feels different.
For energy sector exposure, Dow and Nucor cover key industrial and materials names that tend to move with energy supply cycles. For defense-angle plays, NVIDIA and broader tech infrastructure also face indirect exposure through chip and defense demand shifts.
What to watch
Until these three questions resolve, here is where the signals will come from first:
- Strait of Hormuz crossing data from ship tracking services
- Iranian drone and missile targeting choices in the next 72 hours
- Any U.S. or Israeli statement on nuclear facility strike timelines
- OPEC+ emergency production response
- Fed language on energy inflation pass-through
The baseline scenario is a conflict lasting no more than two months, with oil and defense names outperforming before giving back gains as the premium fades. The tail risk scenario is a different article entirely. Stay positioned for both.
