SYDNEY, March 9, 2026, 19:54 AEDT
Australia’s S&P/ASX 200 tumbled 2.85% to finish at 8,599 on Monday, marking the steepest single-day decline in nearly a year. The index had slid as much as 4.4% during the day before trimming some losses, closing at its lowest level since mid-December. A surge in crude prices rattled investors, sending them fleeing from risk.
The drop didn’t just sting for a day. The benchmark is now down 1.3% for 2026 to date, with energy standing out as the lone sector in the green—a clear indication investors are shifting toward firms set to gain from pricier fuel.
Oil lit the fuse. Brent crude rocketed up to 25%, touching $119.50 a barrel—levels last seen in mid-2022—as the U.S.-Israeli conflict with Iran put a chokehold on supply and stoked anxiety over the Strait of Hormuz. “No obvious off-ramp,” said IG’s Tony Sycamore, warning that real economic fallout is piling up.

Bonds caught the fallout. Yields on Australia’s three-year government debt surged 0.16 percentage point to 4.592%—a level not seen since 2011. The 10-year yield followed, up 0.13 point to 4.977%. “The oil spike was a clear function of uncertainty” about the conflict’s duration, said George Boubouras at K2 Asset Management. Reuters
Materials on the ASX slumped 4.83%, with information technology off 4.77% and financials down 2.06%. Energy eked out a 1.65% gain. Shares of BHP Group dropped 5.1% and Rio Tinto shed 3.8%, while Woodside Energy advanced 2.0%—a stark split in investor sentiment.
Policy sits at the heart of the concern. “Higher for longer” rates could be on the table if oil keeps climbing and inflation expectations shift, Challenger chief economist Jonathan Kearns warned. IMF Managing Director Kristalina Georgieva said global inflation might see a 0.4 percentage point bump if oil prices jump 10% and stay elevated for most of the year. Reuters
Markets have a slim lifeline here. G7 finance ministers are set to weigh a coordinated emergency oil release, a move that might pull crude prices lower—but only if leaders move quickly. Still, Reuters pointed out Kuwait and Iraq have already scaled back output. With the Strait of Hormuz still largely closed off, tight supply keeps equities vulnerable.
On Tuesday, investors aren’t just eyeing the high point for oil—they’re watching the clock, too. “How high and how long” prices stick up will be key for fallout, according to Deepali Bhargava, regional head of research for Asia-Pacific at ING. With crude hovering, much of the ASX could be in for another tough session. Reuters
