ASX 200 set to bounce 1.1% after Monday's 1.5% slide; Wall St mixed and oil holds above US$100

Sentiment: mixed ASX 200 futures: +1.1% (SPI implied open ~8,600)

Tuesday 19 May 2026, pre-open. SPI 200 futures imply the S&P/ASX 200 (XJO.INDX) opening roughly 95 points higher at ~8,600 — a partial recovery from Monday's 125.5-point, 1.5% slide to 8,505.30. Overnight Wall Street was mixed, with the Dow Jones (DJI.INDX) up 0.32% but the Nasdaq Composite (IXIC.INDX) down 0.51% on memory-chip weakness; Brent crude held above US$109/bbl as Iran/Hormuz tensions kept an energy bid in place.

Monday's ASX 200 close

The S&P/ASX 200 (XJO.INDX) closed Monday 18 May 2026 at 8,505.30, down 125.5 points or 1.5% — its softest session in over a week, dragged by miners on weaker iron ore and copper.

• ASX 200 (XJO.INDX): 8,505.30 (-1.5%)
• AU VIX (AXVI.INDX): 14.23 (+11.68%)
• Miner losses: BHP.AU -2.6%, RIO.AU -3.2%, NST.AU -4.1%
• Other losses: GMG.AU -2.7%
• Bouncing: CBA.AU +1.9% (rebound after earlier sell-off)

Miners drove the bulk of the decline as iron ore softened. BHP.AU -2.6% and RIO.AU -3.2% combined account for roughly half the headline index move on weight. Healthcare, consumer services and energy minerals provided partial offsets. CBA.AU bounced 1.9% after a sharp earlier drop, though the broader financials complex finished red.

Overnight Wall Street

US equity benchmarks finished Monday 18 May 2026 mixed, with the S&P 500 (SPX.INDX) at 7,403.05 (-0.07%), the Nasdaq Composite (IXIC.INDX) at 26,090.73 (-0.51%) and the Dow Jones (DJI.INDX) at 49,686.12 (+0.32%).

• S&P 500 (SPX.INDX): 7,403.05 (-0.07%)
• Nasdaq Composite (IXIC.INDX): 26,090.73 (-0.51%)
• Dow Jones (DJI.INDX): 49,686.12 (+0.32%)
• VIX (VIX.INDX): 17.82 (-3.31%)
• US 10Y Treasury yield: 4.63% (+4 bp; year-high territory)

Memory-chip names drove the Nasdaq lower after Seagate's CEO told a JPMorgan conference that new fabs would "take too long" — STX.US closed near -7% and MU.US near -6%, dragging the S&P tech sub-index down roughly 1.1% on the session. NVDA.US and AVGO.US each shed about 1%. The Dow's +0.32% gain leaned on energy and industrials as Brent and WTI rallied on Strait of Hormuz disruption; Trump's call to delay planned Tuesday strikes on Iran capped the move but did not unwind it.

Commodities and FX (AU-relevant)

WTI, Brent and gold all held supportive levels into the AU open: WTI Crude near US$102.49, Brent above US$109/bbl after an intraday range of US$106.87-US$112.69, and gold at US$4,570.80/oz (+0.20%).

• Gold: US$4,570.80/oz (+0.20%)
• WTI Crude: US$102.49 (intraday US$98.60-US$105.21; Yahoo contract-roll noise)
• Brent Crude: US$109.28 (intraday range US$106.87-US$112.69)
• Copper: US$6.336/lb (+0.65%)
• Iron ore 62% Qingdao: ranged near US$110/t in recent sessions
• AUD/USD: 0.7169 (+0.23%)

The energy backdrop favours STO.AU and WDS.AU as the AU session opens — both could see follow-through buying if Brent holds above US$108. Gold at US$4,570/oz is constructive for NEM.AU, NST.AU and EVN.AU after NST.AU's -4.1% Monday hit. Iron ore near US$110/t leaves BHP.AU, RIO.AU and FMG.AU watching for a stabilisation signal after Monday's miners-led sell-off.

Setup for Tuesday's open

• SPI futures imply +95 points (+1.1%) higher at ~8,600 — a partial reversal of Monday's 125.5-point slide.
• Tailwinds: Dow +0.32%, US VIX -3.31%, Brent above US$109, gold US$4,570/oz.
• Headwinds: US 10Y at 4.63% (year-high yield pressure on growth), Nasdaq -0.51% (tech rotation), AU VIX still elevated at 14.23.
• Miner-watch: any BHP.AU, RIO.AU bounce off Monday's -2.6%/-3.2% will set sector tone; iron ore at ~US$110/t is the dominant single input.
• Bank rotation: CBA.AU's +1.9% Monday bounce versus broader financials weakness — does it extend or fade today?

Economic calendar today (AEST)

• 10:00 AEST — ASX cash open
• 10:40 AEST — RBA Assistant Governor (Economic) Sarah Hunter speech
• 11:30 AEST — RBA May Meeting Minutes (decision was +25 bp to 4.35% on an 8-1 vote)
• US: no Tier-1 data overnight; the next major US event is the upcoming FOMC minutes release

What to watch

• Whether the +1.1% gap-up holds through the 10:00 AEST cash open or fades into the RBA minutes at 11:30 AEST.
• The RBA minutes for services-inflation language and the unanimity of the May 25 bp hike (8-1 vote). A hawkish skew typically lifts AUD/USD past 0.7184 (20-day EMA) and pressures rate-sensitive REITs like GMG.AU (after -2.7% Monday) and SCG.AU.
• Brent / WTI direction during AU hours — any Iran headline would amplify the energy bid for STO.AU and WDS.AU and pressure transport names like QAN.AU.
