So when will prices drop in Pennsylvania and across the U.S.?

When asked on April 19 by CNN’s Jake Tapper on “State of the Union” if it’s “realistic” for Americans to expect gas prices to drop below $3, Energy Secretary Chris Wright initially replied “I don’t know,” according to USA TODAY.

But then he said it could happen later this year, or maybe not until 2027. “But prices have likely peaked, and they’ll start going down, certainty with a resolution of this conflict.”

Why are gas prices so high? Turmoil in oil markets

The U.S. and Israel launched joint strikes against Iran in February, and in response Iran blocked the Straight of Hormuz, a major oil-trading route, USA TODAY reports. That left hundreds of tankers unable to enter or leave, causing turmoil in the markets.

The strait has become a key sticking point in ongoing negotiations between the United States and Iran.
