No matter how much oil the U.S. produces domestically, we'll still face huge swings in the price of gasoline. That's because there's a single, global price for oil.
This chart from a new CBO report shows gas prices over time in Canada, Japan and the U.S.
Canada produces all of its own oil; Japan imports all of its oil; and the U.S. produces some and imports some. Yet all three countries show the same wide swings in gas prices. (Absolute price differences are driven by different levels of taxes and fees in the different countries.)
Of course, more U.S. drilling could increase the global supply of oil, lowering the global price a bit for everyone. But more likely, according to the report, is that other oil producers would respond by cutting their own oil production, "diminishing or eliminating the effect" of increased U.S. production.
"Recently, for instance, Saudi Arabia announced that it would reduce its planned expansion of oil production in light of increased production in Brazil and Iraq," the report notes.
