As fuel prices surge across the United States, the impact of geopolitical tensions is increasingly felt in everyday life. The fall of 2026 has seen record-high fuel costs, with diesel and unleaded gas prices reaching unprecedented levels in various states.
For instance, in Pennsylvania, the average diesel price has soared to $6.50 per gallon. Iowa’s farmers are facing diesel costs of over $6 a gallon, and in Alaska, the price for unleaded gas has exceeded $9 per gallon since the onset of the Iran conflict.
Reflecting on the origins of the oil industry, Brian C. Black, a professor of history and environmental studies at Penn State Altoona, notes the industry’s deep-rooted history in Pennsylvania. The oil sector’s journey began nearly 170 years ago in northwestern Pennsylvania, a fact that underscores its longstanding economic significance.

Origins of Oil Trading in Pennsylvania
The oil industry’s roots trace back to 1859 when Edwin Drake discovered oil in Titusville, Pennsylvania. Funded by New Bedford investors seeking alternatives to whale oil, Drake’s discovery paved the way for the burgeoning oil trade in Oil City, 90 miles north of Pittsburgh.
Initially, oil deals were informal, conducted on Oil City’s streets as traders grappled with the value and uses of “rock oil.” This led to the creation of a more formal trading system using a railroad car as a mobile oil exchange on the Oil Creek Railway, facilitating trade between Titusville and Oil City.
As the industry expanded, a dedicated oil exchange office was established in the Arlington Hotel. This transition from handshakes to paper certificates allowed oil to change hands rapidly, with daily trading volumes far exceeding actual production.

In 1874, Oil City became home to a state-chartered Oil Exchange at Center and Seneca streets. The building, dubbed by the local press as “the largest and most elaborate structure ever erected in the Oil Region,” symbolized the speculative nature of the oil trade, with Standard Oil maintaining a presence there.
The Oil City Oil Exchange played a crucial role in crude oil pricing, charging fees per barrel traded. Despite its prominence, by 1895, Standard Oil had monopolized the market, setting prices until the 1911 U.S. Supreme Court antitrust ruling dismantled the trust.
Modern Oil Pricing Dynamics
The dynamics of oil pricing have evolved significantly since the 1970s oil crises. Today, oil prices are determined mainly on exchanges like the NYMEX and Intercontinental Exchange, with fluctuations occurring rapidly and affecting global markets.
Futures contracts, particularly those linked to Cushing, Oklahoma, serve as benchmarks for U.S. oil pricing. However, recent geopolitical events have introduced volatility. The 2026 conflict involving the U.S. and Iran, marked by strikes and strategic blockades, has disrupted oil flow through the Strait of Hormuz.

The closure of this vital passage, as announced by Iran’s Revolutionary Guard, has led to significant disruptions in global oil supply, affecting prices worldwide. Despite Gulf nations’ efforts to bypass the blockade, the market remains volatile, with oil prices hovering around $100 a barrel.
Although the original Oil City exchange building was demolished in 1926, the legacy of its market operations continues to influence today’s global oil pricing mechanisms.
