The quote was regarding JET FUEL stocks.
Crude oil is refined into many different oil products, that are not interchangeable. Jet fuel, kerosene, gasoline, diesel, marine bunker fuel, asphalt etc.
There are many different grades of crude oil. An oil refinery is set up to take a specific grade of crude and to refine it into specific products.
They are not very flexible - they can't just switch to other crude grades or to focus on a specific refined product.
You can't put diesel in a gasoline car and likewise you can't run a plane on marine bunker fuel. The products are not interchangeable when consumed.
Ruwais refinery in the UAE is a large producer of jet fuel but cannot currently export due to the war.
However there are other jet fuel refineries - not least in the US.
Jet fuel exists, it is just more expensive. Demand for it will respond to the high prices - some flights will get cancelled because they'd rather not fly than pay the price.
You do not need to panic fill your petrol car etc.
