Washington, April 30: Escalating conflict between the United States and Iran is driving a sharp increase in fuel prices and placing significant strain on global energy supplies, lawmakers have cautioned, highlighting growing economic pressure worldwide.
At a recent congressional hearing, officials flagged instability around the Strait of Hormuz—a critical artery for global crude shipments—as a key risk to energy markets.
Adam Smith, ranking member of the committee, noted that the economic impact is already being felt domestically. “Gas prices are up by over a dollar,” he said, adding that the crisis has taken on global proportions, with multiple countries reportedly rationing fuel amid worsening economic conditions.
Lawmakers underscored that reduced transit through the Strait has tightened oil supply, while rising fuel and fertiliser costs are likely to accelerate inflationary pressures across both developed and emerging markets.
Defending the military campaign, Pete Hegseth said operational objectives remain paramount despite economic consequences. “We fight to win in every scenario,” he stated.
According to Pentagon officials, the conflict has already incurred costs of approximately $25 billion. Jules W. Hurst III indicated that the bulk of expenditure has been directed toward munitions procurement and operational deployment.
Lawmakers also raised concerns over whether the broader macroeconomic impact is being adequately factored into policy decisions, particularly as energy prices continue to climb.
Dan Caine warned that global risks are intensifying, with modern conflicts increasingly intersecting with economic stability and supply chains.
The Strait of Hormuz remains one of the world’s most vital oil chokepoints, and any sustained disruption has the potential to rapidly constrict supply and elevate prices. The ongoing conflict has amplified these risks, raising uncertainty over the duration of supply constraints and the extent of their impact on energy-dependent economies.
The United States’ longstanding tensions with Iran over its nuclear programme and regional influence have historically triggered similar oil price shocks, underscoring the persistent vulnerability of global energy markets to geopolitical instability.
