Wall Street hits records on Micron's US$1 trillion leap; ASX 200 set to open lower into CPI day

Sentiment: mixed ASX 200 futures: -0.1%

Overnight Wall Street

• S&P 500: 7,519.12 (+0.61%)
• Nasdaq: 26,656.18 (+1.19%)
• Dow: 50,461.68 (-0.23%)
• VIX: 17.01 (+2.53%)

The S&P 500 closed at a record 7,519.12 on 26 May 2026, up 0.61%, as MU.US (Micron) jumped 19% to top a US$1 trillion market value for the first time on a UBS upgrade tied to AI-memory demand. The Nasdaq added 1.19% to its own record, but the leadership was narrow: with the gain concentrated in semiconductors, the Dow's 30 blue chips fell 0.23%, and the VIX rose 2.53% to 17.01 even as the headline indices set new highs. A record close carried by a single name, a lower Dow, and a firmer volatility gauge is the mixed backdrop the ASX inherits at the open.

Commodities & FX (AU-relevant)

• Gold: US$4,507/oz (+0.11%)
• Brent: US$96.36 (-0.32%)
• WTI: US$93.45 (-0.47%)
• Iron ore 62% Fe: ~US$110/t
• Copper: US$6.42/lb (+0.35%)
• AUD/USD: 0.7169 (-0.06%)

Gold held near US$4,507/oz overnight into 27 May 2026, close to flat, keeping NEM.AU, NST.AU and EVN.AU anchored to a steady bullion price. Brent eased to US$96.36 and WTI to US$93.45, stabilising just below the levels behind Tuesday's oil-driven pullback in the local index — relevant with April CPI due at 11:30 AEST. Iron ore 62% Fe sat near US$110/t and copper firmed 0.35% to US$6.42/lb, a constructive read for BHP.AU, RIO.AU and FMG.AU. The AUD/USD slipped to 0.7169.

Key themes for ASX open

The S&P/ASX 200 closed at 8,657.8 on 26 May 2026, down 0.39%, and SPI futures point about 7 points (-0.1%) lower for Wednesday's open despite the offshore records.

• Energy: Brent at US$96.36 and WTI at US$93.45 sit just under the levels that drove Tuesday's pullback; STO.AU, WDS.AU and BPT.AU track the crude move.
• Tech read-through: MU.US +19% carried the Nasdaq to a record, but the ASX lists no large semiconductor maker — for WTC.AU, XRO.AU and NXT.AU the overnight signal is sentiment rather than direct demand.
• Resources: iron ore near US$110/t and copper at US$6.42/lb hold the line under BHP.AU, RIO.AU and FMG.AU, while gold near US$4,507/oz frames NEM.AU and NST.AU.
• Banks and rate-sensitives: April CPI at 11:30 AEST is the pivot for CBA.AU, NAB.AU and other rate-sensitive sectors — a print above the prior 4.6% would reprice expectations for the rate-cut path.
• Property/logistics: GMG.AU (Goodman Group) issued a quarterly update — the main local single-name event into a session otherwise set by the CPI print.

Economic calendar today

• 11:30 AEST — April monthly CPI indicator (ABS), prior annual read 4.6%. Consumer inflation expectations reached 5.9% in April, the highest since 2022. The dominant scheduled catalyst for the local session, landing two hours after the open.
• US cash markets closed during AU hours — S&P 500 and Nasdaq futures were flat after the record cash close, leaving little fresh offshore direction into the open.

What to watch

• Offshore breadth: the overnight record came from one stock — MU.US (+19%) — while the Dow fell 0.23%, leadership too narrow for a resources-and-banks index to mirror.
• US equity futures were flat after the record cash close, so the overnight lead had largely faded by the local open.
• The April CPI print at 11:30 AEST is the session's swing factor, landing two hours into trade against an inflation-expectations reading already at a multi-year high.
