July 2026 Market Update: What AI Uncertainty, Higher Yields, and Geopolitical Tensions Mean for Investors

Markets had a tough time in July 2026, with major stock indexes ending the month slightly down. That said, stocks are still up for the year and not far from their all-time highs. Several things moved markets during the month, including worries about AI spending, rising interest rates, higher oil, and the Federal Reserve holding rates steady.

Many of these developments are part of larger ongoing trends that could keep markets bumpy in the months ahead. At the same time, these trends have helped push markets higher this year. This highlights why it helps to hold a mix of investments and keep a long-term view. Here is a look at what happened in July and what it might mean going forward.

Key highlights from July 2026:

• The S&P 500 and Nasdaq fell -0.1% and -3.2%, while the Dow Jones rose 0.3%.

• International developed markets gained 1.9%, while emerging markets dropped -3.3%.

• The 30-year Treasury yield hit a 19-year high near 5.28%, and the 10-year Treasury yield peaked at 4.74%. The Bloomberg U.S. Aggregate Index fell -1.3%.

• Oil prices rose, with Brent crude briefly topping $100 before closing at $90 per barrel.

• The U.S. Dollar Index (DXY) dipped just under 100 and Gold ended roughly flat.

• Second quarter real GDP grew at an annual rate of 1.5%, down from 2.1% in the first quarter.

• The Federal Reserve held its benchmark interest rate steady in a 9-3 vote.

AI spending raises questions about future profits for big tech

Second quarter earnings reports sparked fresh debate about AI investments. Large technology companies are spending hundreds of billions of dollars building data centers and AI systems. Investors are asking whether all that spending will eventually turn into profits.

In July, a Chinese company called Moonshot AI released a new AI model called Kimi K3. This model is said to match the performance of leading AI models from major U.S. companies. It is also “open weight,” meaning anyone with the right hardware can use it, unlike most top-tier models which are privately controlled. This added to uncertainty about which companies and countries will lead the next stage of AI development.

Middle East conflict briefly pushes oil back above $100

Conflict in the Middle East also rattled markets. Mid-month, U.S. airstrikes on Iranian military sites slowed traffic through the Strait of Hormuz. The conflict spread further when Yemen’s Houthi forces attacked Saudi Arabian oil tankers in the Bab al-Mandeb Strait in the Red Sea.

As a result, Brent crude oil briefly topped $100 per barrel before falling back to around $90 by month-end. For comparison, oil had been as low as $72 per barrel in early July. Higher energy prices affect everyday consumers and businesses through higher fuel costs. Gasoline prices remain around $4.10 per gallon nationally, which could keep overall inflation elevated.

The Federal Reserve holds rates as committee members disagree

At its July meeting, the Federal Reserve kept its key interest rate unchanged. Three of the twelve committee members voted to raise rates, reflecting a level of internal disagreement not seen since September 2016. Markets interpreted this as a sign the Fed could raise rates once by October, and possibly twice by mid-2027.

New Fed Chair Kevin Warsh has also reduced the amount of guidance the Fed gives about future decisions, making it harder for investors to predict how the Fed will respond to changes in inflation or the job market. This uncertainty pushed bond yields higher.

New tariffs add more economic uncertainty

New tariffs also complicated the economic picture in July. After courts ruled that earlier tariffs were illegal, the administration introduced new ones under different trade laws. Most countries now face tariffs of 10% to 12.5%, while some face higher rates.

The full economic impact of these tariffs will take time to play out. Importantly, many of the worst fears about tariffs have not materialized. The economy has continued to grow and the S&P 500 has reached multiple new all-time highs over the past year. Companies have shown they can adapt their pricing and supply chains over time.

Bottom Line

July served as a reminder of why a long-term perspective matters. Market challenges can create opportunities for investors who hold a diversified mix of assets. Staying focused on the bigger picture, rather than reacting to daily headlines, remains the best path toward achieving financial goals.
