KSE-100 Falls as Oil Tops $100 on Mideast Escalation: PSO, OGDC, PPL, MARI in Focus

What the Oil Price Spike Changed for PSX

Heavy selling hit the Pakistan Stock Exchange after Iran and the United States carried out their largest attacks on shipping since their six month old conflict began, pushing international crude prices sharply higher. The benchmark KSE-100 shed nearly 900 points in the opening hours of trading alone, hovering at 171,058.74 by mid morning, before selling deepened through the session and the index settled at 168,865.04. Selling was broad, hitting automobile assemblers, cement, commercial banks, fertiliser makers, oil and gas exploration companies and fuel marketers alike, with index heavyweight stocks such as Pakistan State Oil and Mari Petroleum among the names investors sold.

Why PSO and the E&P Stocks Are in Focus

A jump in international crude cuts different ways depending on where a company sits in the energy chain, and that split matters more than the panic selling on the day itself. Exploration and production companies like Mari Petroleum, OGDC, PPL and Pakistan Oilfields sell oil and gas at prices linked to the international benchmark, so a higher crude price genuinely lifts what they earn on every barrel produced. Fuel marketers like PSO sit on the other side of that equation. They import refined product in dollars and sell it at regulated prices, so a fast jump in crude raises their import bill and working capital needs immediately, while pricing catches up more slowly, adding pressure to a company that is already at the centre of the energy sector's circular debt problem.

Which Stocks, and Why

PSO is a direct name in the selloff and carries the most exposure among fuel marketers, given its size and its central role in circular debt. Attock Petroleum and Shell Pakistan face a smaller version of the same squeeze as other importers of refined fuel. On the other side, Mari Petroleum's dollar linked gas pricing benefits directly from firmer energy prices, while OGDC, PPL and POL see the same tailwind on their oil and gas output, even though their shares were caught up in the broader risk off selling on the day. The rest of the sectors named in the selloff, including banks, cement, fertiliser and autos, do not have a clear, direct link to a Middle East oil shock; their declines look more like broad market caution spilling across the index than a specific hit to their underlying businesses.

What to Watch

The key variable now is how the Iran-US conflict develops from here. A quick de-escalation would likely see both the oil price and PSX sentiment stabilise fairly fast, while a prolonged campaign against shipping would keep crude elevated for longer, deepening the cost pressure on PSO and other importers while sustaining the tailwind for exploration companies. Investors should watch daily Brent and WTI levels, any government response on fuel pricing or circular debt payments to PSO, and whether the KSE-100 stabilises in the sessions ahead or extends its decline.
