Asian Markets Plunge as Hormuz Strait Closure Fuels Economic Fears
Global markets are reeling from the escalating tensions in the Middle East, with Asian and New Zealand share markets experiencing significant declines on Monday. The primary driver of this downturn is the closure of the Strait of Hormuz, a critical chokepoint for global oil supplies, triggering a surge in oil prices and widespread economic anxiety.
The Immediate Impact: A $90 Billion Hit to the ASX
The Australian Securities Exchange (ASX) bore the brunt of the initial shock, shedding $90 billion in value as Brent crude oil prices jumped 25% to surpass $115 a barrel. The ASX 200 closed down 2.9%, marking its worst single-day performance since April of last year. New Zealand’s NZX 50 fell 3%, whereas Japan’s Nikkei experienced a more dramatic plunge of 6%.
Strait of Hormuz: A Vital Artery Under Threat
The Strait of Hormuz, a narrow passage connecting the Persian Gulf with the Gulf of Oman and the Arabian Sea, is the world’s most important oil transit chokepoint. Approximately 20 million barrels of oil and oil products passed through the Strait daily in 2025, representing around 25% of global seaborne oil trade. The closure, following US-Israeli strikes on Iran, has effectively halted commercial shipping, creating a major supply bottleneck.
The Strait is the primary export route for oil from Saudi Arabia, the UAE, Kuwait, Qatar, Iraq, Bahrain, and Iran. Disruptions not only impact oil shipments but also threaten the availability of the world’s spare production capacity.
Oil Price Surge and Inflationary Pressures
The immediate consequence of the Strait of Hormuz closure is a dramatic increase in oil prices. Brent Crude reached its highest level since 2022, settling around $108 a barrel. This surge is already fueling fears of a global economic shock, as inflationary pressures mount. Experts predict an immediate lift in inflation is “all but a done deal.”
US President Donald Trump characterized the oil price spike as a “highly tiny price to pay” for “safety and peace,” but investors remain unconvinced, anticipating potentially lasting economic damage.
Shipping and Carrier Disruptions
The crisis is causing widespread disruption to global shipping. Approximately 3,200 ships, representing 4% of global tonnage, are currently idle in the Gulf region. Major shipping lines, including Maersk, MSC, CMA CGM, and Hapag-Lloyd, have suspended all transits through the Strait of Hormuz, leading to emergency surcharges of $1,500-$4,000 per TEU (twenty-foot equivalent unit).
AIS (Automatic Identification System) reliability is compromised as ships switch off transponders to avoid targeting, making accurate tracking difficult.
Sector Performance: Energy Stocks Buck the Trend
While most sectors experienced significant losses, energy stocks proved resilient, even benefiting from the oil price surge. Yancoal, Karoon Energy, and Whitehaven Coal led the gains on the ASX, with Santos and Woodside also posting strong increases.
Expert Outlook: Bracing for Volatility
Financial analysts are bracing for increased market volatility in the near term. Kiwibank economists suggest that “things are likely to obtain worse before they get better,” while Forsyth Barr investment adviser Mark Fowler notes that markets are beginning to realize the potential for a protracted conflict and its wider ramifications.
There is a cautious hope that markets will rebound quickly once the situation stabilizes, mirroring the response to the Russia-Ukraine crisis in 2022, but the current situation presents unique challenges due to the strategic importance of the Strait of Hormuz.
