Gasoline prices tend to increase when the available supply of gasoline decreases relative to real or expected gasoline demand or consumption. Gasoline prices can change rapidly if something disrupts crude oil supplies, refinery operations, or gasoline pipeline deliveries. Even when crude oil prices are stable, gasoline prices fluctuate because of seasonal changes in demand and in gasoline specifications.

gaz price fluctuates depending on:

1- demande

2- reserve

3- energy inversted / energy extracted

4- speculations

Demand and supply is the basic reason but both of them have their own reason like Russian-Ukraine war that has restricted the supply resulting in a price hike. The situation will worsen when the whole of Europe will need heating of homes and offices resulting in a demand jump.
