ASX 200 close: 8,793.4 (-0.57%) Breadth: ~80 advancers / ~120 decliners Sentiment: bearish
The S&P/ASX 200 closed at 8,793.4 on 23 April 2026, down 50 points or 0.57%, after reports mid-session that the US Navy had intercepted three Iranian oil tankers near India, Malaysia and Sri Lanka. REG.AU surged 16.4% on Federal Budget aged care funding — the day's standout single-name move. Brent crude pulled back to US$98.11 from yesterday's US$101.85 close but remained above pre-ceasefire levels.

- REG.AU +16.4% to $7.03 — Jarden estimated the Budget aged care package lifts REG.AU pre-tax earnings by ~$7m/year, a 6.5% upgrade to consensus NPAT.
- BHP.AU +1.8% after confirming the CMRG iron ore deal and reporting Q3 output above estimates. Copper guidance upgraded to the top of the 1,900-2,000kt range on 29% higher realised prices at US$5.47/lb.
- Energy sub-index rose despite the broader sell-off: KAR.AU +7.8%, tracking Brent's move above US$100 the prior session.
- LYC.AU -6.7% to $18.39 — valuation unwind after a 124% 12-month rally; EV/EBIT above 200x on Q3 numbers.
Sector scorecard
- Best: Energy (+1.2%) — Iran/Hormuz disruption premium persists
- Worst: Consumer Discretionary (-1.8%) — higher fuel costs, CEO turnover at TPW.AU
- Dispersion (best minus worst): ~3 pts
- Materials split: iron ore names firm on BHP.AU CMRG resolution, but gold miners and lithium sold off (BC8.AU -9.9%, CXO.AU -8.1%)
