ASX 200 slides as US-Iran escalation sparks market sell-off

The ASX 200 has been hit by a sharp sell‑off today as hopes for an imminent Middle East peace breakthrough faded again, just as the local market appeared to be regaining momentum. This leaves the ASX 200 poised to finish May in the red, continuing to underperform its global peers.

Following yesterday’s Uunited States (US) strikes near Bandar Abbas – reportedly targeting the head of the Islamic Revolutionary Guard Corps (IRGC) navy, Brigadier Al Azmaei – today brought a further escalation. The US confirmed shooting down four Iranian drones over the strait and striking a drone control station. Iran responded by claiming a retaliatory attack on a US airbase in Kuwait and warned of stronger retribution if strikes continue.

While the US administration is likely to reiterate that peace talks remain on track despite the recent flare‑up, markets were quick to respond, sending crude oil jumping 2.56% to $91.70. This reignited inflation and fuel security concerns, while also pushing bond yields and the safe‑haven US dollar higher.

ASX 200 stocks

Consumer discretionary sector

Capitalising on its defensive characteristics, and supported by yesterday’s cooler‑than‑expected inflation reading – which likely gives the Reserve Bank of Australia (RBA) cover to keep rates on hold at 4.35% next month – the consumer staples sector emerged as today’s best performer.

• Coles lifted 1.17% to $21.61
• Woolworths rose 1.04% to $34.98.

Financials sector

The big banks continued to struggle, reeling from the fallout of tax changes in the Federal Budget. These changes are expected to crimp credit appetite and weigh on property prices – a significant concern given residential mortgages constitute 45% - 50% of the major banks’ asset base.

• ANZ Banking Group fell 2.14% to $34.18
• Commonwealth Bank slipped 1.92% to $161.66
• Westpac fell 1.43% to $35.87
• National Australia Bank dipped 1.38% to $37.23.

Materials sector

The materials sector has been the hardest hit, snapping a five‑day winning streak. Gold stocks led the decline as a surging US dollar and rising yields weighed on bullion, sending it 1.83% lower to $4373.

• Genesis Minerals dived 9.68% to $5.60
• Perseus Mining plunged 9.40% to $4.87
• Resolute Mining dropped 9.11% to $1.17.

Uranium names also fell:

• Silex Systems lost 6.24% to $6.04
• Bannerman Energy dropped 3.24% to $3.58
• Deep Yellow dipped 2.88% to $1.60.

The major iron ore miners also declined:

• Rio Tinto losing 2.38% to $183.11
• BHP shedding 1.45% to $60.38
• Fortescue falling 1.25% to $21.76.

ASX 200 technical analysis

From its mid‑April high of 9021.5, the ASX 200 has since shed 536 points (-5.9%) into last week’s 8485.2 low. The subsequent bounce to yesterday’s high of 8717 failed to gain traction against the 200‑day moving average at 8795. Until the ASX 200 can reclaim that resistance zone, downside risks remain elevated.
