S&P 500 futures started the week near record levels, but much of the overnight momentum faded as rising oil prices and a weaker yen complicated an otherwise supportive backdrop for risk assets. Brent crude traded near $84.40 a barrel, its highest level in about a week, while the 10-year Treasury yield edged up toward 4.67%.
The market’s next major test is inflation. With July U.S. payrolls disappointing and the probability of a September rate hike falling sharply, investors are turning their attention to CPI on August 12 and PPI on August 13 for confirmation that price pressures are still easing.
Technology remained the market’s main pillar, supported by another strong sales update from Taiwan Semiconductor Manufacturing Co. and renewed confidence in AI-linked capital spending. Even so, energy and geopolitics are back in focus as uncertainty around the Strait of Hormuz keeps pressure on crude prices and inflation expectations.
Key Facts
- S&P 500 futures were little changed at 8:00 a.m. ET, while Nasdaq futures rose about 0.1% and small-cap futures lagged in the red.
- Brent crude gained roughly 1% to about $84.40 a barrel, while WTI rose about 1.4% to its highest level in nearly a week.
- USD/JPY climbed 0.6% toward 159, retracing more than half of the post-intervention decline seen after the weak U.S. jobs report.
- U.S. 10-year Treasury yields traded near 4.67%, up about 2 basis points as the curve flattened modestly.
- TSMC reported a 45% jump in monthly sales, reinforcing expectations of sustained AI hardware demand.
S&P 500 Futures and Oil Prices
The core market story is a tug-of-war between cooling rate-hike expectations and renewed energy risk. The weak July employment report reduced the urgency for further Federal Reserve tightening, helping U.S. equities hold near all-time highs. Futures pricing for a September hike fell materially after the data, shifting attention from labor-market resilience to inflation follow-through.
At the same time, oil prices are rising again as negotiations over shipping through the Strait of Hormuz remain unresolved. That matters because crude is not just an energy-sector story; it feeds directly into inflation expectations, transportation costs and consumer sentiment. If oil remains elevated or pushes higher, it could complicate the disinflation narrative just as the Fed appears more data-dependent.
Who is most affected? Large-cap technology continues to benefit from lower perceived rate pressure and strong AI spending signals, but sectors with greater sensitivity to fuel costs and consumer demand could face crosscurrents. Small caps, which initially benefit from lower-rate optimism, may struggle if higher energy prices begin to squeeze margins or revive inflation fears.
With rate-hike fears easing, the biggest near-term risk to the rally may no longer be growth, but whether higher oil prices interrupt the market’s disinflation thesis.
Why AI and geopolitics are colliding in markets
The AI trade remains a powerful support for equities. TSMC’s 45% rise in monthly sales added to evidence that semiconductor and cloud spending are still expanding despite valuation concerns. Meta Platforms gained 2.6% in premarket trading after unveiling a new AI model, while Hewlett Packard Enterprise rose 6% after an analyst upgrade tied to AI infrastructure demand. These updates reinforce the view that hyperscaler backlogs and enterprise hardware investment remain intact.
But geopolitics is becoming harder to ignore. The lack of a final agreement involving Iran and Oman over maritime access through Hormuz has kept traders alert to supply disruption risk. For equity investors, that creates a two-track market: AI and quality growth can still attract capital, while energy, defense-linked names and inflation hedges may gain renewed relevance if tensions persist.
Implications for Investors
For portfolios, the most immediate watch-point is the inflation calendar. A benign CPI reading would likely validate the rally in mega-cap technology and support the view that the Fed can remain on hold. A hotter print, especially if tied to energy pass-through, could quickly pressure duration-sensitive stocks and lift Treasury yields further. That makes this week’s data particularly important for positioning in growth, cyclicals and rate-sensitive sectors.
Investors should also pay attention to market breadth. Earnings growth has broadened beyond AI, with strength in energy, materials and parts of industrials helping offset concentration risk. If oil remains firm and economic growth stays stable, leadership could widen further from the largest technology names into quality cyclicals and commodity-linked equities. That would be a healthier market structure than a rally carried only by a handful of large-cap winners.
Currency and bond markets are another key signal. The yen’s slide toward 159 suggests global carry trades remain active despite a somewhat hawkish tone from the Bank of Japan. If USD/JPY keeps rising and Treasury yields stay elevated, financial conditions may not loosen as much as equity bulls expect. Meanwhile, heavy Treasury issuance this week, including a $58 billion 3-year note auction followed by 10- and 30-year sales, could influence yields and equity valuations.
Single-stock action also points to selective opportunity and risk. Apple fell 1.1% in premarket trading after a downgrade tied to concerns over premium iPhone pricing. Monday.com dropped 9% after results and guidance, while MarineMax agreed to a $53-per-share all-cash acquisition. In biotech, sharp gains in AbCellera and steep losses in Sionna Therapeutics and Tenax Therapeutics underscored the binary nature of clinical-trial catalysts.
The broader takeaway is that equities still have support from earnings, AI spending and reduced odds of further Fed tightening. But with Brent back above $84 and inflation data about to reset expectations, the rally now faces a more demanding macro test.
If CPI confirms continued disinflation, stocks may have room to extend gains from record highs. If oil-driven price pressures reappear, investors should expect sharper rotations across sectors, rates and currencies in the days ahead.
