Sector Performance

Among the eleven S&P 500 sectors, technology led gains with the Technology Select Sector SPDR Fund (XLK) climbing 0.96% to 181.78, driven by strength in semiconductor and software names ahead of Nvidia's fiscal second-quarter results.

The sector rotation reflected a risk-on move into growth-oriented technology while defensive and rate-sensitive sectors lagged.

Macroeconomic Data

On the macroeconomic front, inflation continued its gradual descent toward the Federal Reserve's 2% target. The Consumer Price Index for July rose just 0.1% month-over-month and 3.4% year-over-year, down from 3.5% in June and in line with expectations. Core CPI, which excludes food and energy, increased 0.2% monthly and 2.5% annually, matching forecasts and marking a second consecutive month of deceleration. Shelter inflation eased to 3.2% from 3.3%, while gasoline prices rose 24.6% year-over-year, down from 26.7% in June. The Producer Price Index for July is expected to show annual inflation slowing to 4.9% from 5.5%, with the next release scheduled alongside the GDP revision on August 26. The labor market remains resilient, with initial jobless claims hovering near 200,000, consistent with maximum employment. The 10-year Treasury yield edged lower to 4.700%, down 0.74%, while gold advanced 0.96% to 4,651.43 per ounce as investors sought safe-haven assets amid geopolitical uncertainty.

Monetary Policy

Regarding monetary policy, the Federal Reserve held the federal funds target range unchanged at 3.50% to 3.75% for a fifth consecutive meeting in July 2026, a decision that was widely expected by markets. However, the meeting revealed growing internal division, as three FOMC members dissented in favor of a 25 basis point rate hike, leaving the door open to a potential increase at the September meeting. The Board of Governors unanimously maintained the interest rate paid on reserve balances at 3.65% and the primary credit rate at 3.75%, effective July 30. Market expectations have shifted from pricing in rate cuts toward considering possible rate hikes, driven by persistent core inflation and the energy-price shock stemming from the Iran conflict. The Fed's dual mandate of maximum employment and stable prices remains the guiding framework, with economic activity expanding at a solid pace despite elevated uncertainty.

Geopolitical Risks

Geopolitical developments continued to dominate the risk landscape. Tensions in the Middle East remain elevated following the conflict between the United States, Israel, and Iran, which effectively closed the Strait of Hormuz and disrupted global energy flows. The Trump administration is reportedly considering additional sanctions on Iran that could target companies and countries doing business with Tehran, potentially putting China's purchases of Iranian oil in focus and escalating the broader U.S.-China trade war. China, as Iran's largest trading partner and primary oil buyer, accounts for roughly 90% of Iran's exported oil, and Beijing has leveraged its dominance over rare earth minerals in previous trade negotiations. The disruption to global energy flows poses a severe test of energy security, and a prolonged conflict could exacerbate domestic economic pressures worldwide. Investors are advised to monitor these developments closely, as a drawn-out conflict could trigger a sustained oil shock, higher prices, and downward pressure on equities, while the current market pricing still reflects confidence in a short conflict resolution.
