PSX Plunges Over 2,000 Points Amid Middle East Tensions

Pakistan Stock Exchange Plunges Over 2,000 Points as US-Iran Talks Stagnate and Geopolitical Fears Weigh on Markets Islamabad, May 18, 2026 — Pakistan’s stock market suffered another steep decline on Monday, with the Pakistan Stock Exchange’s (PSX) benchmark KSE-100 index tumbling by 2,507.77 points, or 1.51%, to close at 163,088.30. The sell-off extended a six-session losing streak and reflected deepening investor unease over stalled US-Iran negotiations and escalating tensions in the Strait of Hormuz, which have sent crude prices surging and triggered volatility across Asian markets. The intraday plunge came as the KSE-100 dropped below its pre-war level for the first time since April, when a fragile ceasefire between the US and Iran briefly eased fears of a broader regional conflict. Last Friday, the index had already lost 902.77 points, settling at 165,596.07, as geopolitical tensions and economic uncertainty continued to weigh on sentiment. Analysts warned that market performance would remain closely tied to developments in US-Iran talks and global oil prices, with investors adopting a cautious stance ahead of Pakistan’s upcoming federal budget announcement. The broader sell-off mirrored regional trends, with most Asian indices trading lower on Monday. Tokyo’s market fell 1.0%, Hong Kong dropped 1.4%, and Jakarta experienced the steepest decline at 2.7%. The Strait of Hormuz, a critical chokepoint for global oil supplies, has emerged as a flashpoint, with US President Donald Trump ordering a naval blockade and mine-clearing operations following the collapse of indirect negotiations mediated by Pakistan. Iran’s Revolutionary Guards have warned that any military vessels approaching the strait would be treated as a ceasefire breach, heightening the risk of further disruption to energy markets. The PSX’s struggles underscore the delicate balance Pakistan faces as a mediator between Washington and Tehran. While Islamabad has played a key role in facilitating talks—most recently with Interior Minister Mohsin Naqvi’s visit to Tehran last week—progress remains elusive. Iranian officials have accused the US of rejecting Tehran’s core proposals, while US officials have dismissed Iran’s counteroffers as insufficient. The failure to resolve nuclear and regional security concerns has left the ceasefire on “life support,” according to Iranian Parliament Speaker Mohammad Bagher Ghalibaf, and investors are bracing for prolonged instability. The market’s sensitivity to geopolitical shocks is further compounded by Pakistan’s economic vulnerabilities. The KSE-100’s recent volatility reflects broader concerns over inflation, fiscal deficits, and the potential for capital outflows amid uncertainty. With oil prices climbing above $100 per barrel, global risk appetite has weakened, pushing Asian equities lower and dampening expectations for a near-term recovery in Pakistan’s markets. As the federal budget approaches, traders will closely watch for signals from policymakers on economic reforms and fiscal measures to stabilize investor confidence. However, the overarching concern remains the trajectory of US-Iran negotiations, with any further escalation in the Strait of Hormuz likely to trigger another round of market sell-offs. For now, the PSX’s downward momentum persists, with no immediate signs of a reversal as geopolitical risks continue to dominate investor sentiment.
