The KSE-100 index collapsed 9.57% on March 2, 2026 — its worst-ever single-day absolute loss — as US-Israel strikes on Iran triggered a PSX bloodbath, oil shock, and global market panic. Here’s the full breakdown.

Key Facts at a Glance

It began not with the opening bell, but with silence — the particular, loaded silence of traders staring at screens as the world they priced for had, overnight, become a different one entirely. By 9:22 on a Monday morning in Karachi, the Pakistan Stock Exchange had effectively declared an emergency, triggering a mandatory trading halt after the benchmark KSE-100 index plummeted 15,071 points — nearly 9% — in less than half an hour of trading. When markets finally closed, the KSE-100 had shed 16,089 points to settle at 151,972.99, a decline of 9.57% that constitutes the worst absolute single-day loss in the exchange’s history.

This was no ordinary correction. This was the market’s verdict on a new and dangerous world.

The Trigger: When Washington and Tel Aviv Changed the Calculus

The proximate cause was a seismic geopolitical event that investors had feared but hoped would remain theoretical. Over the weekend of February 28–March 1, 2026, the United States and Israel launched what the White House described as “major combat operations” in Iran, reportedly killing Supreme Leader Ayatollah Ali Khamenei in the opening strikes. Tehran’s response was swift and broad: retaliatory missile barrages targeting US military installations across the Gulf, with blasts reported in the UAE, Qatar, Bahrain, Kuwait, Jordan, and Saudi Arabia.

Dubai International Airport was briefly engulfed in chaos, with footage showing people fleeing a smoke-filled passageway as Iran’s missile salvos — mostly intercepted — sent shockwaves through Gulf infrastructure. President Trump, characteristically blunt, suggested the campaign could last another four weeks.

For energy markets, the threat to the Strait of Hormuz was the true horror. Roughly 15 million barrels of crude oil per day — approximately 20% of the world’s total oil supply — transit the Strait daily, making it the planet’s most consequential energy chokepoint. Marine tracking sites showed tankers piling up on either side, unable to obtain insurance for the voyage. Brent crude surged 9% to $79.41 a barrel in early Monday trading, while West Texas Intermediate climbed 8.6% to $72.79 — the steepest single-day energy price spike since the brief Israel-Iran war of 2025.

The PSX Collapse: Anatomy of a Historic KSE-100 Plunge

Pakistan, as a major net oil importer and a nation whose western border already simmers with Afghan tensions, sits at an especially exposed node in this crisis network. The market did not wait for analysis.

The benchmark index closed at 151,972.99, plunging 16,089.17 points or 9.57% in a single session. It traded within a wild intraday range of 7,580 points, recording a high of 159,328.59 and a low of 151,747.96, reflecting extreme volatility throughout the session. Total trading volume surged to 479.70 million shares.

Monday’s decline marks the KSE-100’s highest-ever single-day fall in absolute terms. Historically, the largest percentage decline was on June 1, 1998 at 12.4%, but due to the lower base of the index at that time, it does not rank in the top ten for absolute point drops. Today’s crash, in sheer numerical magnitude, stands alone.

The circuit breaker fired at 9:22 AM after the KSE-30 fell 5% from its previous close. Following the resumption of trading around 10:22 AM, strong recovery momentum briefly emerged, pushing the index more than 6,000 points higher from its intraday floor — before selling pressure re-emerged and erased those gains.

Market breadth told a brutal story: of the 100 index companies, only one closed higher, 98 declined, and one remained unchanged. The heaviest individual drags were Fauji Fertilizer Company (-1,595 pts), UBL (-1,301 pts), Engro Holdings (-886 pts), Hub Power (-718 pts), and Meezan Bank (-681 pts).

Sector Damage (Index Points Lost):

Pakistan’s Particular Vulnerability

Why did Karachi suffer so much more than London, Frankfurt, or New York? The answer is structural, not merely psychological.

Pakistan imports the vast majority of its energy needs. Every $10 rise in the per-barrel price of crude translates to roughly $2.5 billion in additional annual import costs — a meaningful sum for an economy currently navigating IMF-supervised stabilisation. Analysts were quick to connect the dots: “Elevated oil prices are highly detrimental to Pakistan’s external account, and persistently high commodity prices are likely to trigger a new wave of inflation,” said Waqas Ghani, Head of Research at JS Global.

The country was already navigating a dual-front stress test. Pakistan’s Defence Minister had described the situation with Afghanistan as tantamount to “open war,” and the KSE-100 has now fallen nearly 19% from its record high of 189,166.83 set in January 2026, edging dangerously close to the 20% threshold commonly associated with a formal bear market.

In the week before Monday’s collapse, the index had already shed 5,107 points — a 2.9% weekly decline. The PSX crash of March 2 was therefore not a surprise attack on a healthy market, but a breaking point on an already-fractured one.

The Global Picture: A Coordinated Rout

Pakistan’s pain was severe, but it was not isolated. Global markets opened the week sharply lower after the US-Israel strikes on Iran rattled investors across every time zone. In the US, S&P 500 futures were down 1.1%, Nasdaq 100 futures fell 1.5%, and the Dow Jones futures slid 1.1%. In Europe, the pan-European Stoxx 600 fell nearly 1.8% during Monday’s session.

Asian markets joined the rout: India’s Sensex fell 1.3%, Taiwan’s benchmark lost 0.9%, and Singapore’s dropped 2.3%. Bangkok’s SET fell 4%, while the UAE and Kuwait temporarily closed their own stock markets entirely, citing “exceptional circumstances.”

Gold surged to $5,408.10 per ounce — a 3.1% single-day gain — as the classic safe-haven flight took hold. The US dollar strengthened against most emerging-market currencies, adding a secondary pressure on Pakistan’s rupee and its debt-servicing capacity.

Standard Chartered’s Global Head of Research Eric Robertsen noted that investors had already been underpricing geopolitical risk, pointing to commodity-linked currencies outperforming as markets began pricing exposure to scarce resources and terms-of-trade winners.

What Analysts and Economists Are Saying

The bull case for containment: Quantum Strategy’s David Roche argued that the market impact depends almost entirely on duration. If the conflict remains short and contained, he noted, the risk-off move and oil spike could be brief — referencing the June 2025 pattern, when Israel struck Iranian nuclear sites and equities sold off sharply at the open before recovering once it became clear the Strait of Hormuz was not disrupted.

The bear case for escalation: Goldman Sachs estimated that oil prices could blow past $100 a barrel if there is an extended disruption to Strait of Hormuz flows — a scenario with severe implications for Pakistan’s current account and inflation trajectory.

The structural concern: Arif Habib Limited (AHL), in its latest note, highlighted that despite the near-term pressure, the tail-end of March typically marks the beginning of a seasonally bullish period for the KSE-100, and that following an almost 15% drawdown, the index appears poised for a rebound towards the 175,000 level, with sustained support above 165,000 likely to underpin such a move.

Recovery Scenarios: Three Possible Paths Forward

Scenario 1 — Swift De-escalation (30–45 days) If the US-Iran conflict remains largely aerial and does not close the Strait of Hormuz, global oil markets could retrace sharply. Pakistan would benefit from falling crude prices, a stabilizing rupee, and renewed risk appetite for frontier markets. KSE-100 recovery to 165,000–170,000 is plausible by April.

Scenario 2 — Prolonged Campaign (60–90 days) A sustained conflict, particularly one that throttles Strait of Hormuz traffic, would push Brent above $90–100, forcing Pakistan to burn through foreign exchange reserves at an accelerated pace and potentially triggering an emergency IMF review. The KSE-100 could test support at 140,000.

Scenario 3 — Regime Change and Uncertainty The death of Ayatollah Khamenei opens a power vacuum scenario in Iran that few analysts have priced. Ben Emons of FedWatch Advisors argued that leadership strikes in Tehran raise regime-change tail risks and leave an uncertain endgame — potentially the most destabilizing medium-term outcome for all regional markets, including PSX.

Actionable Insights for Investors

This is not a moment for panic, but it is a moment for precision. Here is what the data suggests:

1. Energy-linked plays carry double risk. Pakistani oil marketing companies and refineries face margin compression from higher crude costs even as revenues appear to rise in PKR terms. The sector’s net impact is negative for most listed names.

2. Banks face a credit cycle test. Commercial banks, which bore the largest index-point losses today, face rising non-performing loan risk if a fresh inflation cycle materializes. However, their healthy net interest margins — built during the high-rate era — provide a buffer. Selectively accumulating quality names on dips remains a viable strategy.

3. Fertilizer stocks are caught in a vice. Higher natural gas costs (linked to LNG imports) and falling farm-gate prices from commodity pressure could squeeze margins. Fauji Fertilizer’s 1,595-point drag on the index today reflects this anxiety.

4. Technicals matter now. AHL’s observation that the KSE-100 remains 7% above its 200-day moving average is significant — it represents a long-term structural support that institutional investors will defend. Breach of 145,000 would mark genuine capitulation territory.

5. Watch the Strait, not just the headlines. The single most important variable for Pakistan’s macro outlook over the next 30–60 days is not battlefield developments, but whether marine traffic through the Strait of Hormuz normalizes. A functional strait = manageable oil shock. A blocked strait = crisis conditions.

The Bigger Picture

Pakistan’s PSX bloodbath today is, in one sense, a microcosm of a broader truth about the global economy in 2026: the world has underpriced geopolitical risk for years, and it is now receiving the bill. From Karachi to Frankfurt, from the Gulf tanker lanes to Wall Street’s futures desks, the US-Israel strikes on Iran have created a risk-repricing event of genuine historical significance.

The Pakistan Stock Exchange, with its volatile frontier-market character, tends to price these shocks faster and harder than more liquid peers. That same characteristic means it tends to recover faster when clarity returns. The question Pakistani investors — and the government — must answer urgently is: what decisions, made today, preserve the most options for that recovery?
