Petrol Up Rs3.34, Diesel Up Rs5.27 for Aug 19: PSO, APL and Shell Stocks in Focus

The Oil and Gas Regulatory Authority (OGRA) raised petrol and high-speed diesel (HSD) prices for the 24 hours starting August 19, continuing the daily fuel-price review mechanism the government introduced on July 17 amid volatile global oil prices. Petrol rose Rs3.34 a litre to Rs334.54, while diesel climbed Rs5.27 to Rs395.69. The move follows an even steeper hike a day earlier, when petrol jumped Rs5.77 and diesel Rs6.47. Since the daily-review mechanism began, petrol has risen a cumulative Rs22.24 a litre and diesel Rs66.18 a litre.

Why PSO, APL and Shell Stocks Are in Focus

Pakistan State Oil, Attock Petroleum and Shell Pakistan sell fuel at prices OGRA sets under a formula, so the retail price move itself does not change their regulated per-litre margin. What it can do is lift the value of the fuel already sitting in their storage tanks and pipelines. Marketing companies typically hold several weeks of imported and refined stock bought at the previous, lower price. When the government raises the retail price, that existing inventory is sold at the new, higher rate, producing a one-off inventory gain in the following quarter's accounts. The size of that gain scales with how much stock a company is holding and how large the price move is, so a Rs3.34 to Rs5.27 move is a modest, not a decisive, boost.

Which Stocks, and Why

PSO, as the largest fuel retailer with the biggest storage network, sees the largest absolute rupee gain from any single price step, though it also carries the heaviest exposure to circular debt in the power and gas sectors, which can offset inventory gains elsewhere on its balance sheet. APL and Shell Pakistan are smaller and carry less debt, so a comparable inventory gain moves their per-share profit by more, proportionally, even if the absolute rupee amount is smaller. None of the three see their core per-litre OMC margin change from this move, since that margin is fixed separately by OGRA and reviewed less frequently than the daily ex-refinery price.

What to Watch

The bigger swing to track is the cumulative one: petrol is now up Rs22.24 and diesel Rs66.18 a litre since the daily-review mechanism started in mid-July, a far larger move than any single day's headline. Watch OGRA's next fortnightly OMC margin review and the companies' quarterly results for how much of that inventory effect actually shows up in profit, since a falling international oil price or a rupee reversal in the interim can just as quickly erase it.
