Why fuel price increasing globally?

Fuel prices are increasing globally mainly because oil supply is getting tighter while demand is still high, especially due to ongoing geopolitical tensions in the Middle East involving countries like Iran, which creates fear of supply disruption; at the same time, major oil-producing groups like OPEC sometimes reduce production to keep prices high, and when global economies grow, more fuel is needed for transport and industry, increasing demand further, while currency fluctuations, transportation costs, and refining expenses also add to the price, so even a small disruption in global oil flow quickly makes petrol and diesel more expensive worldwide.
