As the national average for a regular gallon of gas broke the all-time record in the United States on Tuesday

many are wondering how long this surge may continue and when prices at the pump will finally go down.

As of Monday evening, the average cost for a gallon of gas in the country is $4.06, according to AAA.

The current price, up 6 cents from Sunday and 45 cents from last week, is the closest it has ever been to the all-time record of $4.11, set in July 2008.

There are a few factors contributing to the increase, but the main reason is the Russian invasion of Ukraine.

Since the country is one of the biggest energy suppliers, crude oil prices have dramatically risen.

A barrel of U.S. crude oil settled at $119.40 per barrel, up 3.2%, after earlier touching $130.50.

Brent crude, the international standard, settled at $123.21 per barrel, up 4.3%, after earlier topping $139, the Associated Press reported.

Gas remains the most expensive in California, with the average cost at $5.34, the only state with an average above $5.
