Oil prices have maintained a four-day streak of gains, influenced by new economic measures announced by US President Donald Trump aimed at crippling Iran's economy. West Texas Intermediate for October delivery traded above $84 a barrel, while Brent crude finished near $92.
Trump described the new measures as "Economic Warfare and Isolation on an unprecedented scale," urging allies to join the United States in isolating and defeating the "Iran threat." The announcement comes as a 60-day deadline on a U.S.-Iran memorandum of understanding expires, with Trump asserting that Iran "will never have a nuclear weapon" and is "in big trouble" with "300% inflation."
According to Miad Maleki, a senior fellow at the Foundation for Defense of Democracies and a former senior U.S. Treasury official involved in sanctions, Iran's oil exports significantly decreased under previous sanctions, taking about two years to fall from two million barrels per day to below 200,000 barrels per day. Maleki characterized current efforts as a "maximum pressure campaign on steroids," potentially disrupting oil flows that account for a substantial portion of Iran's GDP and government budget. He also noted Treasury Department efforts to hinder Iran's ability to repatriate revenue from oil sales in China.
Maleki highlighted that gasoline shortages could exert faster pressure than reduced oil revenue, warning of potential domestic unrest similar to past protests triggered by fuel price increases. He advised against signaling a timetable for any blockade, suggesting it could allow Iran to wait out U.S. actions or escalate tensions.
The conflict, including potential closure of the Strait of Hormuz, has been characterized by the International Energy Agency as the "largest supply disruption in the history of the global oil market." This has led to comparisons with the 1970s energy crisis, marked by supply shortages, currency volatility, inflation, and heightened risks of stagflation and recession. While past oil shocks have seen prices eventually stabilize, the current situation's impact on interest rates, stock markets, and bond markets is being closely watched.
Despite the oil shock, some economists argue that modern economies are less vulnerable due to lower oil intensity and more flexible labor markets. The IMF has revised its world GDP growth rate forecasts upward for 2026 and 2027, with AI-driven demand offsetting some negative effects of the oil supply shock. A survey of economists indicates a consensus that the U.S. economy will likely avoid a recession.
