US Equities Close Volatile July as AI Spending Soars and 10-Year Yield Peaks

US equities wrapped July with a volatile close as the 10-year Treasury yield (^TNX) surged to its highest level since January 2025, igniting market turbulence.

AI Capital Outlays Reshape Market Momentum

Big‑tech giants are ramping up artificial‑intelligence investments, prompting the "Magnificent Seven" to forecast 2026 capital expenditures between $720 billion‑$745 billion. This infusion of capital aligns with the Nasdaq Composite (^IXIC) gaining roughly 1 %.

■Microsoft (MSFT): Shares jumped 15 %, marking a historic rally.

■Amazon (AMZN): Earnings beat expectations, lifting the stock 15 %.

■Apple (AAPL): Services and China revenue shortfall dragged the stock 7 % lower.

■Meta (META) & Alphabet (GOOGL): Continued AI spend bolsters growth outlook.

Treasury Yield Spike and Fed Stance: Market Sentiment

The Fed's decision to hold rates steady, coupled with a lack of forward guidance, pushed the 10‑year Treasury yield to 4.73 %, a peak not seen in over a year. Bond sell‑offs nudged equity buying, contributing 0.5‑0.7 % gains to the Dow Jones Industrial Average (^DJI) and S&P 500 (^GSPC).

■10‑Year Yield: 4.73 % (highest since Jan 2025).

■Fed Outlook: Emphasis on stability, forward‑look uncertainty.

■Weekly Index Performance: Dow +0.53 %, S&P 500 +0.70 %, Nasdaq +1.00 %.

Energy Prices and Global Trade Flows

Traffic disruptions in the Strait of Hormuz lifted WTI crude to $85 /barrel and Brent to $90 /barrel. Rising energy costs strain consumer budgets, while simultaneously boosting energy‑sector equities.

■WTI: $85 /barrel.

■Brent: $90 /barrel.

■Strait of Hormuz Traffic: Decline, heightening regional risk premiums.

Investor Sentiment and Forward Outlook

The University of Michigan's latest consumer‑confidence survey signaled a broad improvement, reversing earlier downtrends. Yet, elevated energy prices and the surging Treasury yield temper risk appetite.

■Consumer Confidence: Broad uptick.

■Risk Appetite: Cautious amid high yields.

■Future Outlook: Sustainability of AI spend remains pivotal.

Markets will treat AI investment as a long‑term growth engine, but 10‑year Treasury yields and energy‑price volatility will continue to steer capital flows. In the short term, equity markets will oscillate around these two dynamics; over the longer horizon, AI‑driven sectoral transformation is likely to dominate.
