Markets cheer agreement to reopen Strait of Hormuz as fears over energy supply disruptions ease
Global financial markets rallied on Monday while oil prices plunged after the United States and Iran announced a deal to end months of conflict and reopen the strategic Strait of Hormuz, easing concerns over global energy supplies and inflation.
The agreement, brokered by Pakistan, is scheduled to be formally signed in Switzerland on June 19 and is expected to bring an end to a three-month war that had disrupted oil shipments and rattled international markets.
The Strait of Hormuz, through which around 20 percent of the world’s crude oil supply passes, was effectively closed by Iran shortly after the conflict erupted following US-Israeli strikes on Iranian targets on February 28.
US President Donald Trump confirmed the breakthrough on Sunday, announcing that shipping through the critical waterway would resume.
“The Deal with the Islamic Republic of Iran is now complete,” Trump wrote on social media.
“I hereby fully authorize the toll-free opening of the Strait of Hormuz, and, simultaneously herewith, authorize the immediate removal of the United States Naval blockade. Ships of the World, start your engines. Let the oil flow!”
Iran’s Deputy Foreign Minister Kazem Gharibabadi later stated that the agreement would bring an immediate end to hostilities and pave the way for further negotiations aimed at securing a comprehensive settlement within the next two months.
The announcement triggered a sharp sell-off in oil markets as traders responded to expectations of restored supply flows.
West Texas Intermediate (WTI) crude dropped 5.6 percent to $80.16 per barrel, while Brent crude fell 4.1 percent to $83.77 per barrel.
Both benchmark contracts have retreated significantly from the highs above $110 per barrel recorded shortly after the conflict began.
The decline in energy prices also eased fears that rising fuel costs could trigger a fresh wave of inflation across major economies.
Analysts said lower oil prices could reduce pressure on central banks, particularly the US Federal Reserve, which had recently faced renewed calls to tighten monetary policy following stronger-than-expected inflation and employment data.
Stephen Innes, Managing Partner at SPI Asset Management, said the market reaction reflected growing confidence that inflationary pressures may ease.
“Oil down takes the inflation impulse down. Lower inflation risk takes some of the Fed-hike premium out of the curve. Lower yields give duration and growth equities room to breathe,” he said.
He cautioned, however, that investors would be watching closely to ensure the agreement is fully implemented.
“This is a first-step deal, not a final peace settlement. The market will now trade verification,” Innes added.
Stock markets across Asia posted strong gains as investors embraced the prospect of reduced geopolitical tensions and lower energy costs.
Japan’s Nikkei 225 index surged 5.4 percent, while South Korea’s market gained more than five percent, led by technology and semiconductor stocks.
Japanese technology investor SoftBank and chipmakers Tokyo Electron and Advantest recorded significant gains, while South Korean giants Samsung Electronics and SK Hynix also advanced sharply.
Investor sentiment was further boosted by the recent blockbuster initial public offering of SpaceX, which raised $75 billion and reignited enthusiasm for artificial intelligence-related investments.
Elsewhere, markets in Shanghai, Sydney, Singapore and Taipei climbed more than one percent, while Hong Kong and Wellington also closed higher.
Indonesia’s Jakarta Composite Index jumped more than four percent as easing energy concerns supported the rupiah, which strengthened to its highest level since May.
The reopening of the Strait of Hormuz is expected to restore one of the world’s most important oil shipping routes, helping to stabilise global supply chains and energy markets.
The waterway’s closure had contributed to higher fuel prices, increased shipping costs and concerns about inflation in economies heavily dependent on imported energy.
Investors will now focus on the formal signing ceremony in Switzerland and subsequent negotiations between Washington and Tehran, which are expected to address broader issues including regional security and Iran’s nuclear programme.
Despite lingering uncertainties, financial markets reacted positively to what many see as the most significant diplomatic breakthrough in the Middle East in recent years.
