Oil back above $100 as US to blockade Iranian ports after peace talks fail

Rising Oil Prices Amid US-Iran Blockade Threat

Global oil prices surged past the $100 mark on Monday as Asian energy markets reopened, driven by the failure of recent US-Iran peace talks and President Donald Trump’s announcement of a potential port blockade. Brent crude climbed 7.3% to $102.30, while West Texas Intermediate rose 8.7% to $104.94. The breakdown in negotiations has fueled worries about a deepening global energy crisis.

Strait of Hormuz as Critical Trade Route

The Strait of Hormuz, a vital artery for global energy flow, remains central to tensions. A fifth of the world’s oil shipments transit through this narrow waterway, which has seen disrupted traffic since the conflict began on 28 February. While some nations like India and Malaysia secured safe passage for their vessels, others faced delays. The recent US-Iran agreement on a conditional ceasefire briefly eased concerns, but the deal now appears to have collapsed.

Market Reactions and Analyst Predictions

Analysts suggest that oil prices may stay high due to ongoing uncertainties regarding the blockade’s execution and potential expansion of shipping disruptions. “Expectations are tied to whether the blockade is fully enforced, if disruptions spread further, and if diplomatic efforts resume,” noted Chua Yeow Hwee, an economist from Singapore’s Nanyang Technological University. Major Asian stock indexes dipped on Monday, with Japan’s Nikkei 225 falling 0.7% and South Korea’s Kospi dropping 1%.

“The truth is, oil prices are not as high as they normally would be” given the scale of supply disruptions, said Saul Kavonic of MST Marquee. “But if that doesn’t happen, oil prices will head higher.”

US Blockade Implementation Details

US Central Command (Centcom) confirmed the blockade of Iranian ports will begin at 10:00 ET on Monday, targeting vessels attempting to enter or exit the region. The measure will apply “impartially” to ships of all nations, but Centcom clarified it will not interfere with vessels heading to non-Iranian ports. Trump’s directive, posted on Truth Social, emphasized the move as a response to Tehran’s threats to attack ships using the strait.

Iran’s parliamentary speaker, Mohammad Bagher Ghalibaf, stated the country “will not submit to any threat” in a local media statement. The Islamic Revolutionary Guard Corps (IRGC) Naval Forces warned that military vessels approaching the strait would be seen as breaching the ceasefire and face severe consequences. The situation highlights the fragility of regional stability and its impact on global markets.
