Weekly Market Update: Oil Shock Pushes Yields to Fresh Highs

Markets traded lower this week as the conflict in the Middle East intensified and oil prices surged 17%.

The S&P 500 and Nasdaq each declined roughly 2%, while the Russell 2000 finished the week down about 1.5%. Most equity factors also moved lower, including Growth, Value, and Equal Weight, as market participation weakened.

Momentum and High Beta were the two exceptions. Both outperformed after lagging in recent weeks, helped in part by continued weakness across semiconductor stocks.

At the sector level, Energy and Utilities led the market higher. Meanwhile, Consumer Discretionary declined nearly 7% as investors considered how higher fuel and transportation costs could affect household spending and corporate profit margins.

Bonds also traded lower as interest rates rose across the yield curve. Longer-maturity bonds underperformed, which is typically what we’d expect when investors become more concerned about inflation. The VIX climbed back toward 20 late in the week, while the U.S. dollar strengthened as interest rates rose and market volatility increased.

Key Takeaways

Oil Prices Rise as the U.S.-Iran Conflict Escalates

The United States carried out a twelfth consecutive night of strikes this week, while Iran continued targeting tankers traveling through the Strait of Hormuz. The strait is one of the world’s most important energy corridors and carries a significant share of the global oil trade.

Meanwhile, Yemen’s Houthi rebels added another layer of uncertainty by threatening a naval blockade against Saudi Arabia. That threat raises the possibility of disruption not only in the Strait of Hormuz, but also across shipping routes in the Red Sea.

Oil prices responded quickly. West Texas Intermediate crude climbed above $90 per barrel, while Brent crude, the international benchmark, briefly touched $100. Both reached their highest levels in roughly six weeks.

At the same time, there’s been little visible diplomatic progress. Secretary of State Marco Rubio said Iran was “not serious about talks,” reducing near-term expectations for a negotiated resolution.

Why It Matters: The conflict had shown signs of stabilizing, but each additional strike, tanker attack, or threat to shipping routes introduces a new risk premium into oil prices.

The issue isn’t simply whether oil reaches a particular price. What matters is how long prices remain elevated and whether those higher costs begin working their way through transportation, manufacturing, utilities, and consumer spending.

In other words, the longer the conflict continues, the greater the chance that an overseas geopolitical event turns into a broader inflation and economic-growth concern for the United States.

Rising Oil Prices Push Treasury Yields to Fresh 52-Week Highs and Revive Expectations for a Fed Rate Hike

This week’s move in Treasury yields was a direct extension of the Middle East story.

The 10-year Treasury yield rose above 4.70%, reaching a new 52-week high, as investors began pricing a greater risk that higher energy costs could keep inflation elevated.

Expectations for Federal Reserve policy also shifted. Fed funds futures now assign a greater than 80% probability to an interest-rate increase at the Fed’s September meeting, up from approximately 50% one week ago.

That’s a meaningful change in a short period of time. It suggests that investors are no longer viewing the rise in oil prices as an isolated market event. Instead, they’re considering whether higher energy costs could affect the Fed’s broader inflation outlook.

Why It Matters: Treasury yields are now closely tracking developments in the Middle East, which highlights how interconnected energy markets, inflation expectations, and interest rates have become.

Higher yields can create pressure across several parts of the economy. They can raise borrowing costs for households and businesses, weigh on bond prices, and make it more difficult for highly valued stocks to justify their current prices.

However, the key question for the Fed is whether the rise in energy prices is temporary or whether it begins affecting wages, consumer expectations, and the prices of other goods and services.

A short-lived oil shock may not change the Fed’s plans. A prolonged inflationary shock could.

Alphabet’s Strong Quarter Was Overshadowed by a Growing AI Capital-Spending Commitment

Alphabet reported second-quarter results Wednesday that exceeded expectations across several major areas.

Revenue increased 24% to $120 billion, Google Cloud revenue jumped 82%, and operating margins expanded. By most traditional measures, it was a strong quarter.

However, Alphabet shares still declined approximately 5% in after-hours trading as investors focused on the amount of spending required to produce that growth.

The company increased its 2026 capital-expenditure guidance to between $195 billion and $205 billion, up from its previous range of $180 billion to $190 billion. Management also indicated that spending would increase again in 2027.

Meanwhile, quarterly free cash flow turned negative for the first time in the company’s history as capital spending exceeded the cash generated by its operating businesses.

Why It Matters: The market doesn’t appear to be questioning whether artificial intelligence is contributing to growth. Alphabet’s results provide strong evidence that it is.

Instead, investors are asking a more difficult question: How much will companies have to spend to generate that growth, and when will those investments begin producing an attractive return?

That distinction matters because revenue growth alone doesn’t necessarily create shareholder value. Companies also need to demonstrate that the cash invested in data centers, chips, energy, and other AI infrastructure can eventually produce sustainable profits and free cash flow.

For now, the market appears willing to support substantial AI investment. However, investors are becoming less willing to accept an unlimited spending commitment without clearer evidence of the eventual payoff.

Next Week’s Calendar Could Answer Many of These Questions

Several of the market’s biggest current debates will be tested within a two-day period next week.

The Federal Reserve’s two-day meeting concludes Wednesday, July 29, with an interest-rate decision and press conference. Investors will be listening closely for signs that officials view higher energy prices as a temporary disruption or as a reason to reconsider the path of monetary policy.

Microsoft and Meta will report earnings after the market closes that same day. Their results will provide two more important data points in the debate over AI-related spending, revenue growth, and investment returns.

Then, on Thursday, investors will receive the advance estimate of second-quarter gross domestic product and the June Personal Consumption Expenditures Index, the Fed’s preferred inflation gauge.

Apple and Amazon will report earnings after Thursday’s closing bell, adding additional information about consumer demand, cloud computing, and corporate technology spending.

Why It Matters: Nearly every major question discussed this week will face a real-world test next week.

The inflation data may show whether price pressures were already building before the latest rise in oil. The Fed’s comments may clarify whether officials are prepared to respond to energy-driven inflation. Meanwhile, the technology earnings reports may reveal whether AI spending is continuing to generate enough growth to justify its rapidly rising cost.

Any one of these events could move markets. Taken together, they could determine whether this week’s volatility was a temporary response to geopolitical uncertainty or the beginning of a more meaningful shift in the market’s outlook for inflation, interest rates, and corporate profits.
