Key Stories for US Markets

NYSE & NASDAQ News & Impact

MINERSIron ore held firm at $95.34 per tonne (+0.14%), providing support for the major ASX iron ore producers — BHP, Rio Tinto, and Fortescue (FMG) — though Fortescue is separately seeking what it describes as a swift return to normalised China trade conditions, underscoring that the geopolitical backdrop for the sector remains uncertain even as spot prices stabilise.

ENERGYWTI crude's 2.35% fall to $85.01 per barrel and Brent's equivalent drop to $92.17 are negative for ASX-listed energy producers including Woodside and Santos, while the US Energy sector ETF (XLE) fell 0.83% overnight — partially offset by LNG export prices holding at $13.55 per MMBtu and natural gas nudging higher, which provides some cushion for Woodside's LNG-exposed earnings stream.

TECHThe 1.78% overnight fall in the US XLK technology ETF and sharp declines in global semiconductor names (STX -6.51%, MU -5.83%) will weigh on ASX technology and data centre-adjacent names at the open, with the sector facing further event risk from Nvidia's earnings report on August 26 — a key read-through for any ASX names with AI infrastructure or cloud exposure.

GOLDGold's rise to $4,640.80 per ounce (+0.36%), with intraday prints cited closer to $4,680–4,725, is a constructive signal for ASX-listed gold miners including Northern Star (NST), Evolution Mining (EVN), and Newmont's Australian operations — the metal is being driven by a combination of Iran sanctions risk, US fiscal concerns with debt exceeding $40 trillion, and safe-haven demand alongside Bitcoin.

AUDThe Australian dollar faces headwinds from a firmer DXY (99.0, +0.20%) and USD/JPY holding at 158.90, but the dominant near-term driver will be tonight's CPI print at 21:30 ET — a headline m/m of 0.9% (versus -0.1% prior) could prompt markets to reassess RBA cut timing, potentially supporting the AUD and pressuring rate-sensitive ASX sectors including REITs and utilities.

MATERIALSCopper rose 0.30% to $6.599 per pound and iron ore held steady, but aluminium fell 2.20% to $3,406 per tonne and silver dropped 1.33% — a mixed commodities backdrop that will produce divergent performance across ASX materials names, with copper-exposed stocks (OZ Minerals acquiree BHP, Sandfire Resources) better placed than aluminium-heavy names such as South32.

US Sectors to Watch

Sector Outlook · Signal & Rationale

Energy

WTI crude fell 2.35% to $85.01 on Iran sanctions and demand concerns, directly pressuring ASX oil and gas producers.

▼ Negative bias

Financials

US financials (XLF +1.29%) outperformed overnight and rising short-end yields (2Y at 4.24%) support net interest margin, a mild positive read-through for ASX banks.

▲ Positive bias

Technology

Global semis sold off sharply (XLK -1.78%, MU -5.83%, STX -6.51%) ahead of Nvidia's August 26 earnings, creating direct headwinds for ASX tech names.

▼ Negative bias

Materials

Context & Analysis

Macro Themes

Top 5 Structural Themes · Global & US Market Implications

Structural Driver

US sanctions on Iran announced August 24 escalate Middle East supply risks while US-Canada tariff collapse adds trade friction, structurally lifting energy and gold prices amid $40T US debt and flattening yield curve. This dynamic pressures global inflation and forces central banks including the RBA to balance growth and price stability at 4.35% cash rate.

Current Catalyst

August 24 sanctions plus 50% tariffs on $20B Canadian goods triggered WTI oil drop of 2.5% to ~$85/bbl and gold rise of 1% to $4,680–4,725/oz, with Bitcoin up 2% toward $80k.

Overnight Briefing

Global Macro Overview

US Treasury Secretary Scott Bessent escalated geopolitical risk on August 24 by announcing sweeping new sanctions on Iran and threatening 50% tariffs on CAD $20 billion of Canadian goods after US-Canada trade talks collapsed, with Canadian retaliation set to take effect September 8. Meanwhile, the US public debt crossing $40 trillion and the Treasury's plan to expand buybacks of long-dated bonds drove long-end yields down approximately 5 basis points, contributing to a flattening curve even as 2- and 10-year yields rose 5 basis points on the session. Risk sentiment was decidedly mixed — gold pushed toward multi-month highs near $4,640–4,725 per ounce while oil fell 2.35% to $85.01 (WTI), its second decline in 14 sessions, and Bitcoin extended a remarkable rally of roughly 25% over just over a week to approach the $80,000 level. The VIX rose 4.76% to 15.85, reflecting elevated near-term uncertainty ahead of Nvidia earnings on August 26, PCE inflation data, and Fed Chair Kevin Warsh's Jackson Hole address on August 28.

For Asia-Pacific markets opening today, the dominant cross-asset signal is a tech and semiconductor selloff — Nvidia fell approximately 3%, while Seagate, SanDisk, and Micron each shed around 6% — which will weigh on tech-heavy regional indices already under pressure from geopolitical friction. The KOSPI's 3.12% decline and Nikkei's 0.74% fall on August 24 underscore the region's sensitivity to both US tech momentum and China's ongoing rare-earth and tungsten export curbs that are squeezing Japanese manufacturers. Iron ore held relatively firm at $95.34 per tonne (+0.14%), offering a modest stabiliser for Australian miners, while the AUD faces crosscurrents from a slightly stronger DXY (99.0, +0.20%) and today's critically important Australian CPI release at 21:30 ET, where the market forecasts headline CPI rebounding to 0.9% month-on-month and the trimmed mean ticking up to 0.4%. The ASX 200's prior-session gain of 0.49% to 9,103.1 may prove difficult to sustain given the weight of offshore tech weakness and rising bond yields.

Market-Moving Events · Americas

TECHTechnology was the clear laggard on August 24, with the XLK sector ETF falling 1.78% as semiconductor names bore the brunt of pre-Nvidia earnings rotation — Seagate (STX) and SanDisk (SNDK) each shed roughly 6.5%, Ciena (CIEN) fell 6.02%, and Micron (MU) dropped 5.83%, the four worst performers in the S&P 500. Nvidia itself fell approximately 3% ahead of its August 26 earnings report, which is being watched as a bellwether for the entire AI infrastructure capex cycle.

MACROUS Treasury Secretary Bessent announced 'economic D-Day' sanctions on Iran on August 24, compounding risk-off pressure in energy markets and driving WTI crude down 2.35% to $85.01 per barrel. Simultaneously, the collapse of US-Canada trade talks triggered a threat of 50% tariffs on $20 billion of Canadian goods, with Canada's retaliatory measures due to take effect September 8, adding a new layer of trade-war risk to North American supply chains.

BONDSThe US Treasury announced plans to expand buybacks of long-dated bonds using its approximately $1 trillion general account, a move designed to manage elevated term premiums with US public debt now exceeding $40 trillion. Despite the buyback announcement pushing long-end yields modestly lower on the day, the 2-year and 10-year Treasury yields both rose 5 basis points to 4.24% and 4.74% respectively, keeping the yield curve in focus ahead of PCE data on August 26.

EARNINGSNvidia's August 26 earnings report is the single most anticipated near-term catalyst for global equity markets, with the pre-print selloff in semis on August 24 reflecting both positioning nervousness and rotation out of the AI trade into defensives — consumer staples (XLP +1.70%), financials (XLF +1.29%), and utilities (XLU +1.05%) were the top three S&P 500 sector performers on the session. Top individual gainers included Expedia (EXPE +5.44%), Dollar Tree (DLTR +4.01%), Church & Dwight (CHD +3.78%), and Altria (MO +3.60%), all classic defensive or value plays.

CRYPTOBitcoin rose 1.56% to $78,964 on August 24, extending a rally of approximately 25% over just over a week and approaching the psychologically significant $80,000 level, while Ethereum gained 0.73% to $2,481. The move is occurring alongside gold's multi-month highs, suggesting both assets are attracting safe-haven and inflation-hedge flows amid geopolitical escalation and US fiscal concerns.

Market-Moving Events · Europe

MACROEuropean indices posted a subdued but broadly resilient session on August 24 — the FTSE 100 gained 0.35% to 10,854.3 while the Euro Stoxx 50 dipped 0.22%, the DAX fell 0.11%, and the CAC 40 slid 0.37% — as US geopolitical escalation (Iran sanctions, Canada tariffs) kept sentiment cautious without triggering a sharp risk-off move in the region.

ECBThe ECB remains on hold, with analysts now raising their estimates of the neutral rate and flagging the possibility of future 25 basis point hikes should energy-driven inflation pressures persist — a dynamic being closely watched ahead of PCE data from the US on August 26 and Fed Chair Warsh's Jackson Hole speech on August 28, which will set the tone for global central bank expectations into September.

BOEThe Bank of England is also seen holding at current rates, with no major policy decisions or market-moving commentary emerging from UK policymakers on August 24; the FTSE 100's outperformance (+0.35%) relative to continental peers reflected the index's heavier weighting toward commodities and financials rather than any positive domestic policy catalyst.

GEOUS sanctions on Iran and the threatened 50% Canadian tariffs are being closely monitored in European capitals for second-order effects on energy trade flows and transatlantic supply chains — European energy markets will be particularly sensitive to any further escalation in Middle East tensions given the region's ongoing exposure to LNG and oil import pricing.

Market-Moving Events · Asia-Pacific

KOREAThe KOSPI was the worst-performing major index on August 24, falling 3.12% to 6,696.96, as the global semiconductor selloff — triggered by pre-Nvidia earnings de-risking — hit South Korea's chip-heavy market hard, with names like Samsung and SK Hynix facing derivative pressure from the 5–6% declines in Micron, Seagate, and SanDisk on Wall Street.

CHINAChina's ongoing rare-earth, tungsten, and graphite export restrictions on Japan remain firmly in place, with shipments in key categories described as at or near zero, while exports of those same materials toward the US have quietly risen — a deliberate strategic asymmetry that is reshaping critical mineral supply chains across the region and putting sustained cost pressure on Japanese electronics and defence manufacturers.

JAPANThe Nikkei 225 fell 0.74% to 65,528.09 on August 24, with the Nikkei VIX easing slightly to 28.13 (-0.88%), as the combination of a weaker US tech tape, persistent China mineral export curbs, and USD/JPY holding at 158.90 weighed on exporters and semiconductor-related names; markets await any fresh commentary from the Bank of Japan ahead of the Jackson Hole gathering.

HKThe Hang Seng fell 1.89% to 25,517.33, the second-sharpest decline among major indices on August 24, reflecting both the global risk-off in technology and semiconductors and ongoing concerns about China's domestic demand outlook — Shanghai's SSE Composite also dropped 0.59% to 3,882.01.

RBAThe RBA is holding its cash rate at 4.35% in a hawkish stance emphasising subdued demand and inflation vigilance, and all attention now turns to tonight's Australian CPI release (21:30 ET) — the market forecasts a sharp rebound in headline CPI to +0.9% month-on-month from -0.1% prior, and a trimmed mean of +0.4% m/m, with the year-on-year rate expected to ease to 3.3% from 3.8%, a print that will directly shape RBA rate expectations for the remainder of 2026.

Economic Calendar

Time (ET)	Ctry	Event	Impact	Prior	Forecast
10:00	US	CB Consumer Confidence	Medium	90.8	90.3
21:30	AU	CPI m/m	High	-0.1%	0.9%

Risks & Watch Items

Key Risks · Geopolitical · Supply Chain · Policy

MACROAustralian CPI at 21:30 ET tonight is the highest-impact local event of the week — a headline m/m print of 0.9% (versus -0.1% prior) would be the largest single-month acceleration in recent memory and could materially reprice RBA rate-cut expectations, moving the AUD and ASX rate-sensitive sectors sharply.

EARNINGSNvidia reports earnings on August 26 — any guidance miss or commentary suggesting a slowdown in data centre demand will extend the current semiconductor selloff and hit ASX tech and materials names with AI supply-chain exposure.

TARIFFCanada's retaliatory measures against the threatened US 50% tariffs on $20 billion of Canadian goods take effect September 8 — monitor for escalation or negotiation signals this week, as a broadening trade war adds to global growth and inflation uncertainty relevant to RBA deliberations.

GEOChina's rare-earth, tungsten, and graphite export curbs on Japan remain in force with key categories at zero shipments — any escalation or extension of these restrictions to additional materials or trading partners would directly impact ASX-listed critical minerals producers and technology supply chains.
