Latest Developments in the US-Iran-Israel Situation: Three Possible War Scenarios and Their Impact on Oil Prices and US Stocks.

As of March 3, 2026, the US and Israel have launched military strikes against Iran, Iran’s Supreme Leader Khamenei has been killed, and the Strait of Hormuz has been blocked. Here are the key points of the three possible scenarios:
🔴 Path 1: Rapid Resolution (Probability 10%-15%)
Core Logic: The US and Israel achieve limited objectives (destroying nuclear facilities/missile bases) and withdraw through diplomatic channels.
Key Features:
Military operations are controlled within 4 weeks, with no aim to occupy or change the regime
Iran accepts a ceasefire due to inability to continue counterattacks
International mediation (Oman, China) helps de-escalate the situation
Impact:
Oil prices: Brief spike to $90-100 before falling back
Strait: Temporarily closed then reopened
Markets: V-shaped rebound in US stocks
🟡 Path 2: Prolonged Standoff (Probability 40%-45%)
Core Logic: Both sides engage in long-term, controlled attrition, normalizing the conflict.
Key Features:
The Strait of Hormuz remains “semi-closed,” with oil tankers rerouting around the Cape of Good Hope
The US and Israel continue precise strikes, Iran conducts proxy attacks
All parties aim to control conflict boundaries to avoid full-scale escalation
Impact:
Oil prices: Fluctuate between $100-130
Economy: Global growth slows by 0.5-1 percentage points
Markets: US stocks continue to decline by 15-20%
🔥 Path 3: Full Out-of-Control (Probability 35%-40%)
Core Logic: An unexpected trigger ignites regional war, leading to a global crisis.
Key Triggers (any one):
US military base suffers major damage, significant casualties
Saudi Arabia/UAE oil fields are hit
Iranian nuclear facilities are attacked, causing radioactive leaks
Long-term comprehensive blockade of the Strait
Chain reactions:
Within 48 hours: Large-scale US retaliation, Iranian missiles cover Gulf oil fields
Within 1 week: Oil prices break through $180-200, global financial markets meltdown
Within 1 month: US stocks plunge over 20%, triggering a recession comparable to 2008
📊 Quick Comparison
Dimension | Rapid Resolution | Prolonged Standoff | Full Out-of-Control
Probability | 10-15% | 40-45% | 35-40%
Oil Price | $90-100 | $100-130 | $180-200+
Strait Closure | Brief closure, then reopen | Semi-closed, normal rerouting | Long-term full blockade
Market Reaction | V-shaped rebound, then decline 15-20% | Continuous decline, weekly drop over 20%
🔑 Key Conclusions
Rapid resolution is largely ineffective: strategic trust collapses, Iran unlikely to accept “symbolic concessions”
Prolonged standoff remains the baseline scenario: aligns with interests of all parties, but risks unexpected escalation
Full out-of-control scenario significantly increases in probability: Iran enters “survival crisis” mode, blockade becomes leverage
Key variables: decisions by Iran’s new leadership, whether Israel opens a new front, attitudes of Gulf countries, effectiveness of China and Russia’s mediation.
