S&P 500 Hits Record 7,798.99 as Inflation Cools, Rate Hike Fears Ease

The S&P 500 closed at a fresh record of 7,798.99 on August 13, climbing 0.65 percent after US producer prices held flat in July, well below economist expectations of a 0.2 percent increase. The benign inflation reading reinforced market bets that the Federal Reserve will not raise interest rates at its September meeting, easing a key concern that had weighed on stocks earlier this summer.

Why inflation data triggered the rally

The July Producer Price Index came in unchanged month-on-month, while year-over-year it rose 4.7 percent, down from 5.5 percent in June. This followed a tame consumer inflation reading on Wednesday. Stephen Brown, an economist at Capital Economics, said a September rate hike is now looking unlikely based on the trend. The reading gave investors confidence that the Federal Reserve under new Chair Kevin Warsh will not feel compelled to tighten policy quickly.

Tech stocks and earnings drive the advance

Memory chip makers led the charge, with SanDisk surging 13.7 percent and Micron Technology jumping 4.2 percent. Meta Platforms rose 2.8 percent and Microsoft added nearly 1 percent. Jay Hatfield, CEO of Infrastructure Capital Advisors, said the strength reflects an earnings boom rather than speculation. Strong forecasts in recent weeks from companies including Microsoft and Amazon have reduced investor concerns about massive spending on AI data centres, he noted.

Weekly gains mask Friday weakness and consumer softness

Despite Thursday’s record close, the S&P 500 slid 0.2 percent on Friday to 7,785.76, though the benchmark still posted its third consecutive weekly gain of 0.4 percent. Retail sales for July fell unexpectedly, and consumer confidence in August dropped to 51 from expectations of 54.5, according to the University of Michigan survey. Art Hogan of B. Riley Wealth Management cautioned that summer trading volumes remain light, making it hard to assign credibility to recent moves.

Oil retreat and geopolitical risks weigh on sentiment

Brent crude futures fell more than 2 percent to $87.07 per barrel, while West Texas Intermediate slid more than 2 percent to $81.25. The decline reflects falling oil demand amid uncertainty over Gulf shipments through the Strait of Hormuz as the US-Iran conflict continues. The US Treasury’s 30-year bond auction on Thursday drew the highest yield since 2001 at 5.216 percent, signaling bond market caution despite stock market optimism.

Final Thoughts

The S&P 500’s record close hinges on easing inflation and lower rate-hike odds, but Friday’s pullback and weak consumer data suggest caution ahead. With earnings growth tracking 50 percent year-over-year and the index up 14 percent in 2026, valuations remain elevated amid geopolitical tensions.
