Brent Jumps 6% as Iran Keeps Strait of Hormuz Closed Amid Sanctions Pressure

Key Facts

1Oil prices are heading for a second weekly gain as the U.S. vows to impose the toughest sanctions in history against Iran.
2U.S. Treasury Secretary Scott Bessent stated that a return to large-scale military combat is unlikely.

Amid a sharp escalation in geopolitical tensions, Brent crude oil is on track for a robust weekly gain of nearly 6%, holding near its highest level in a month. This price surge is driven by the United States' commitment to impose the toughest economic sanctions in history against Iran, sparking deep concerns over supply stability. According to reports, Iran's continued closure of the strategic Strait of Hormuz has intensified global supply uncertainty, marking a significant shift in energy maritime risk.

On the policy front, U.S. Treasury Secretary Scott Bessent stated that a return to large-scale military combat remains unlikely despite the maximum economic pressure campaign. Markets are now focused on assessing the impact of waterway closures on the global supply-demand balance, as disruptions in the Strait of Hormuz typically trigger an immediate risk premium in prices. These developments coincide with market data showing improved trade balances in the Eurozone, potentially signaling resilient industrial demand despite volatile energy costs.

Looking ahead, traders are closely monitoring technical resistance levels as crude approaches its monthly highs. Investors are also awaiting the release of the Commitment of Traders (CFTC) report in the U.S., which will be critical in determining the scale of bullish positioning resulting from current geopolitical frictions.
