Quick take: U.S. attacks Iran — impact on the markets and economy

Talha Khan, political economist

The United States and Israel conducted coordinated strikes across Iran over the weekend, explicitly targeting senior Iranian leadership. Iranian state media has confirmed the death of Ayatollah Ali Khamenei. This represents a direct strike at regime command rather than a limited infrastructure campaign. Iran has responded with missile and drone attacks against Israeli territory and U.S. positions in the Middle East region (including the UAE, Bahrain, Qatar and Kuwait). Over the weekend, gold jumped as investors sought a safe‑haven hedge. At the same time, U.S. Treasury futures traded higher early Monday, while U.S. equity index futures declined ahead of the market open.

How this differs from the June 2025 attack

The June 2025 events were primarily about deterrence — targeted strikes aimed at degrading capabilities and signaling boundaries without touching the core of Iran’s political architecture. By contrast, the 2026 operation directly intersects with regime stability, the succession process and IRGC cohesion. If power consolidates quickly in Tehran, retaliation is likely to be forceful but still controlled. If the leadership splinters or competing factions emerge, the path of escalation becomes far more unpredictable.

Impact on oil prices

Oil markets were already elevated going into the weekend, with Brent crude settling near $72.87 per barrel, its highest level in several months ahead of the confirmed strike. Brent prices rose further early Monday, nearing $79 per barrel, as traders reassess supply risk through the Strait of Hormuz. Saudi and other Gulf equity markets that were open over the weekend declined on the news, while regional sovereign spreads widened rather than gapping to crisis levels. The initial reaction reflects shock and uncertainty but not panic selling.

The structure of the oil move matters more than the headline price

What matters isn’t just how high oil prices go, but what part of the market is moving. If the jump is mostly in near‑term prices, it usually signals that investors are bracing for short‑lived disruption, which is what we are seeing so far. But if prices rise across longer dated contracts as well — and are accompanied by wider credit spreads and weaker equities — it points to a deeper worry about lasting supply risks.

Mechanically, the key vulnerability is shipping

Iran produces roughly 3-3.3 million barrels per day of crude oil, with exports (mainly to China) accounting for around 1-2% of global output. Nearly all those exports transit the Strait of Hormuz. Globally, flows through the Strait account for roughly 20% of global petroleum liquids consumption. This weekend, Iran’s Revolutionary Guard and state-aligned media claimed the strait had been effectively shut, warning that passage was unsafe; yet tanker movements continued, underscoring the gap between rhetorical escalation and operational reality. While attempted disruption could still send oil prices sharply higher, history suggests Iran can generate volatility but a sustained closure would be much more difficult.

Energy markets have generally bounced back quickly from geopolitical shocks

Since 1967, none of the major military conflicts involving Israel have had a continuing effect on oil prices except for the Arab-Israel War in 1973, which led to an oil embargo by the Organization of Petroleum Exporting Countries (OPEC). This was especially impactful because OPEC controlled over half the global oil supply at the time. The global oil system today is more flexible than during past Gulf crises. Non-OPEC supply, particularly U.S. shale, can respond more quickly to price incentives. Strategic reserves exist as buffers. Energy intensity of GDP is lower than during prior oil shocks. These factors do not eliminate vulnerability to disruption in the Gulf, but they reduce the probability that a brief confrontation becomes a structural energy crisis.

Conclusion

For now, markets are adjusting to higher geopolitical risk but are not yet positioned for a prolonged regional war. Whether that changes will depend less on the strike itself, which has already reshaped the political landscape in Tehran, and more on what happens next: how the succession unfolds, how far Iran chooses to retaliate, and whether energy flows from the Gulf remain secure in the coming days.
