Pakistan's benchmark KSE-100 index (the main index of the Pakistan Stock Exchange) fell more than 3,000 points, or roughly 1.8%, during intraday trading on Monday, settling near 170,794 points. The sell-off was driven by uncertainty over whether a second round of US-Iran negotiations, originally expected to be held in Islamabad, would go ahead. The decline reverses a strong rally from the previous week, when the index had gained nearly 6,750 points on hopes of easing Middle East tensions and softer monetary policy, though it remains well below its all-time high of 189,167 points reached in January.
