[Deep Dive] US-Iran Ceasefire Expectations and Global Market Relief Rally

Global Markets Rally on Easing Geopolitical Risks

As of July 27, 2026, the two-week-long armed conflict between the US and Iran has entered a temporary lull, triggering a relief rally across global stock markets. Following reports that US airstrikes paused on July 24, the market interpreted this as a preliminary signal for a 'US-Iran ceasefire' and diplomatic negotiations, quickly restoring risk-on sentiment.

Crucially, international oil prices plummeted by nearly 7% as fears of supply disruptions subsided. This sharp decline in oil prices alleviated market concerns over prolonged inflation, serving as a primary driver for the equity market's upward momentum.

A Complete End to the War, or a Temporary Pause?

Despite the short-term market rebound, it is premature to conclude that the crisis has been fully resolved. Key uncertainty factors remain:

• Iran's Hardline Stance: In a July 27 briefing, the Iranian Foreign Ministry denied initiating negotiation requests to the US, maintaining a firm posture.

Strait of Hormuz Blockade: Military tensions and the effective blockade of the Strait of Hormuz—a vital artery for global energy logistics—have not been resolved.

Trauma of Past Broken Deals: Investors remain cautious due to the failure of previous ceasefire agreements, such as the Islamabad Memorandum of Understanding (MoU) in June.

Implications for Investors and Outlook

The market is closely monitoring the diplomatic efforts of mediating nations and the trajectory of potential 'US-Iran ceasefire' talks. In the short term, falling oil prices may create a favorable environment for equities by reducing inflationary pressures. However, with the uncertainty surrounding the Strait of Hormuz still lingering, managing portfolio volatility remains essential. Investors should maintain a cautious approach, waiting for concrete signs of a diplomatic resolution rather than adopting premature optimism.
