US-Iran War: What Happened and What It Means for Markets

The global financial landscape has entered a state of emergency. Following the launch of “Operation Epic Fury” on February 28, 2026, long-simmering tensions between the United States, Israel, and Iran have erupted into open military conflict. For traders at DBG Markets, the narrative has shifted decisively: we have moved from economic data dependency to full geopolitical risk repricing.

US-Iran War Escalation: What Happened？

On Saturday, February 28, the United States and Israel launched a massive, coordinated air and missile campaign against Iran. Strikes targeted Tehran, Isfahan, and Karaj, specifically aiming at nuclear facilities and military command infrastructure.

Most notably, U.S. and Israeli officials confirmed the death of Iran‘s Supreme Leader, Ali Khamenei, during the initial wave of attacks—a development later acknowledged by Iranian state media. The removal of Iran’s highest political and religious authority marks an unprecedented escalation that fundamentally alters the strategic balance of the Middle East.

Iran responded swiftly. Multiple waves of ballistic missiles and drones were launched toward Israel and U.S. military bases in Kuwait, Bahrain, and the UAE. This retaliation signals Tehrans intent to broaden the theater of conflict rather than contain it.

While the Strait of Hormuz has not been formally closed, traffic through this critical energy corridor has dropped sharply—estimated at nearly 38%. Major oil tankers are rerouting or delaying transit due to missile risks and soaring war-insurance premiums. Given that roughly one-fifth of global oil supply passes through this channel, even a partial disruption materially tightens global energy logistics.

This is no longer a proxy conflict; it is a direct military confrontation with systemic global implications.

Why Did It Happen？

The conflict erupted after nuclear negotiations in Geneva collapsed. Throughout early 2026, the U.S. and Iran engaged in indirect talks—often mediated by Oman—focused on Irans uranium enrichment, ballistic missile capabilities, and regional military posture. However, negotiations failed to bridge core strategic differences:

· Enrichment Deadlock: Iranian negotiators resisted far-reaching limits on uranium enrichment.

· Insufficient Concessions: The U.S. judged proposed concessions as insufficient to meaningfully constrain nuclear breakout capability.

· Ultimatums: Washington imposed strict deadlines, warning of military consequences should diplomacy fail.

By late February, U.S. officials concluded that diplomacy was unlikely to prevent Iran from advancing toward “viable weapons capability within days.” This assessment became the operational justification for military action.

What It Means for the Markets？

1. Oil Market Shock

The oil market saw the most immediate and violent reaction.

· Brent and WTI surged on fears of sustained supply disruption.

· War-risk premiums for shipping spiked, driving up transportation costs.

· Energy equities rallied aggressively as investors hedged against supply shortages. Even without a full closure of the Strait of Hormuz, reduced traffic materially tightens near-term supply. If disruptions persist for weeks, oil could structurally reprice higher, reintroducing global inflationary pressure.

2. Safe-Haven Surges

Precious metals saw a classic “risk-off” flow. Gold rallied strongly, regaining ground above $2,700/oz (marking a monthly high after a correction from Januarys record highs). Meanwhile, the US Dollar strengthened broadly—a textbook response to geopolitical shocks where capital preservation takes precedence over growth assets.

3. Equity Market Repricing

Global equity indices sold off sharply at the open. However, this shock did not occur in a vacuum. Even before the escalation, early signs of distribution were visible in the U.S. equity market. Recent data had begun to cast doubt on the “soft landing” narrative, with sticky core inflation and moderating consumer demand.

The war now acts as a catalyst, accelerating an already fragile market structure rather than creating weakness from scratch.

Macro Pressure Meets Geopolitical Shock

The combination is particularly destabilizing:

· Inflationary Spark: Rising oil prices threaten to re-ignite inflation expectations.

· Fed Policy Constraint: Higher inflation complicates the Federal Reserves ability to pivot toward rate cuts.

· Valuation Pressure: Elevated rates pressure equity valuations, especially in the growth and technology sectors.
