Why Are Gas Prices Increasing?

Experts attribute the price hikes to concerns surrounding potential disruptions to oil supply. Approximately 20% of the world’s oil supply transits through the Strait of Hormuz, a critical waterway bordered by Iran. While there isn’t a physical blockade, oil tankers are increasingly avoiding the Strait due to threats from Iran, creating pressure on other oil-producing regions and driving up prices.

The price of crude oil, a key component of gasoline, is currently above $70 a barrel. This surge in crude oil prices is directly contributing to the increases seen at the pump.
