Pakistan’s efforts to mediate a ceasefire between the United States and Iran sent shockwaves through the Pakistan Stock Exchange (PSX) on Tuesday, triggering one of the largest single-day rallies in recent history.

Within minutes of the announcement, the benchmark KSE-100 index surged by more than 12,000 points, prompting an automatic trading halt under market regulations as volatility spiked. Traders described the surge as a “peace-driven rally,” reflecting optimism over the diplomatic breakthrough.

By 9:35 AM, the KSE-100 index stood at 164,035, marking an increase of 12,362 points, or 8.15 percent.
