DID Press: Global oil markets experienced a sudden shock on Thursday, March 12, immediately following the release of Iran’s new Supreme Leader Ayatollah Seyyed Mojtaba Khamenei’s first statement. Emphasizing the continued closure of the Strait of Hormuz and ongoing military operations, crude oil prices surged nearly 9%, pushing Brent back above $100 per barrel.
The Financial Times described the statement as a “tough, challenging signal,” noting that Iran warned Gulf Arab states that U.S. military bases would remain legitimate targets unless closed. This stance dashed market hopes for a softer approach under Iran’s new leadership and signaled Tehran’s intent to impose significant costs on the global economy while redefining the regional balance of power.
The Strait of Hormuz, through which roughly 20% of the world’s oil passes, is a critical chokepoint. The Financial Times, citing the International Energy Agency, stated that combined disruptions from the strait’s closure and repeated attacks on Gulf energy infrastructure constitute “the largest supply shock in oil market history.”
The impact extended beyond oil. Brent’s rise above $100—a 38% increase since the conflict began—triggered declines across Wall Street, with major U.S. indices including the Dow Jones, S&P 500, and Nasdaq all falling over 1% as investors brace for prolonged high inflation.
The new leader’s initial statement made it clear to global markets that the current conflict will not end quickly. With the Strait of Hormuz at the heart of this geopolitical standoff, oil prices are expected to remain elevated and volatile, heightening the risk of sustained economic instability and inflationary pressures worldwide.
