The current market is defined by a tense push-and-pull between diplomatic optimism and military hardlines from the US and Iran.
On one hand, any news of dialogue or de-escalation sends a wave of relief through the markets. For example, the announcement of a two-week ceasefire on April 8 caused the S&P 500 (SPY) to jump 2.55% while the main oil ETF (USO) fell nearly 10%. This shows how eagerly investors want to believe in a peaceful resolution, pushing stocks to record highs on hopes of avoiding a wider war.
However, this optimism is fragile and repeatedly shattered by military actions. Iran’s Revolutionary Guard Corps (IRGC) continues to issue threats, and the recent US seizure of an Iranian-flagged vessel near the Strait of Hormuz caused after-hours oil prices to surge over 6%. These events serve as a harsh reminder that the situation on the ground remains volatile, placing a cap on how high the stock market can rally.
The entire conflict revolves around the Strait of Hormuz. This narrow waterway is a critical chokepoint, with about 20% of the world's oil and LNG passing through it. The cycle is straightforward: First, diplomatic talks lead to a partial reopening, and a risk premium on oil prices begins to fade. Second, a military incident or a threat of a new blockade occurs, and that risk premium is slapped right back on, causing prices to spike.
This chain of events didn't start yesterday. It began with a US-Israeli airstrike on Iran on February 28, which triggered retaliatory missile attacks from Iran and US strikes on Iranian oil infrastructure, like the key export hub on Kharg Island. This history shows that the 'Strait-Oil-Inflation-Asset Price' connection is now a constant factor in the market, with each side using economic and military pressure to gain leverage.
Ultimately, the market is navigating a path between two extremes. It's betting that the conflict will be a 'managed de-escalation' rather than an all-out war. But this interpretation is being tested daily, and the upcoming ceasefire deadline on April 22 will be a major test of which force—diplomacy or military confrontation—will win out.
