In a significant development that could reshape global energy markets, oil prices have plummeted while stocks have surged following the announcement of a tentative agreement between the United States and Iran to restore peace. US President Donald Trump confirmed that the pivotal Strait of Hormuz, through which approximately 20% of the world’s oil and liquefied natural gas flows, will be reopened. Brent crude, the global oil benchmark, witnessed a sharp decline of 4.7%, settling at $83.24 a barrel.

Asian markets reacted positively, with Japan’s Nikkei 225 showcasing a remarkable gain of 5% and the South Korean Kospi rising 5.2%. Investors welcomed the news, keenly aware of how the ongoing US-Iran conflict had previously escalated energy prices, disrupting the fragile economic landscape.

The agreement is set to be formally signed on June 19 in Switzerland, and has been facilitated by Pakistan’s mediation efforts. Iran's Deputy Foreign Minister, Kazem Gharibabadi, confirmed the deal's finalization during a state television broadcast, prompting Trump to declare on social media, “Let the oil flow!” However, energy market analysts, such as Vandana Hari from Vanda Insights, have cautioned that the lack of detailed terms surrounding the agreement could inject volatility into the market.

This uncertainty may lead to fluctuating oil prices in the coming week. Although the reopening of the Strait of Hormuz is a monumental step, the waterway has been effectively closed since late February, following airstrikes initiated by the US and Israel against Iran. Tehran has threatened retaliation against vessels traversing this crucial maritime route, raising alarms over potential supply shortages.

As the global energy market adjusts, experts warn against expecting an immediate return to pre-war operational levels in the Strait. Andrew Lipow of Lipow Oil Associates noted that the presence of mines would delay full access to the waterway, with the clearing process potentially taking anywhere from a few weeks to six months. Additionally, a significant backlog of tanker traffic must be addressed before normal operations can resume.

Former US Navy Rear Admiral Mark Montgomery echoed these concerns on the BBC’s Today programme, stating that it might take up to 45 days for the movement of vessels and the normalization of oil pumping to stabilize.

As the dust settles from this historic framework deal, the global market waits with bated breath to see whether this breakthrough can genuinely stabilize energy prices and restore equilibrium across vital supply chains.
