The S&P 500 closed at a record high on Thursday after a combination of strong AI-related earnings and softer wholesale inflation gave investors confidence. Futures were mostly flat heading into Friday’s session, though Dow futures dipped 0.1%.

The calm didn’t last long. Tensions between the US and Iran rattled sentiment early Friday after the US threatened to keep its naval blockade of Iran running indefinitely.
The threat raised fears about shipping disruptions through the Strait of Hormuz, a key route for global oil supply. Brent crude futures rose 1.7% to $88.51 a barrel and West Texas Intermediate climbed 1.9% to $82.79 in early trading.

The threat put supply fears back in play.

Higher oil prices matter to markets because they can feed into broader inflation. If inflation stays elevated, the Federal Reserve may feel pressure to raise interest rates rather than hold them steady.
The yield on the 10-Year Treasury Note moved up 2 basis points to 4.67% on Friday, a sign that some investors are already adjusting their rate expectations.
Despite the early pressure on the Dow, S&P 500 and Nasdaq 100 futures each edged up 0.1%, showing a split in how different parts of the market were reacting.
Asian markets pointed to a positive open for US stocks. South Korea’s KOSPI rose more than 1.4% and Japan’s Nikkei gained 0.8%.
With no major earnings on Friday’s calendar, investors shifted attention to the week ahead. Retail giants Target and Walmart are both scheduled to report next week.
Nvidia’s earnings, set for August 26, are drawing particular interest from investors watching the AI sector.
On the economic data side, retail sales figures and the University of Michigan’s consumer sentiment reading were due Friday. Both reports offer a snapshot of how American consumers are holding up.
The S&P 500 and Nasdaq were still on track for weekly gains despite Friday’s uncertainty. The Dow was the weakest of the three, weighed down by oil-driven inflation concerns.
The mixed futures picture heading into Friday reflected the competing forces at play: strong earnings and cooling inflation on one side, rising oil prices and geopolitical risk on the other.
Traders were watching whether oil prices would continue to climb and whether that would change the tone heading into next week’s retail earnings season.
The 10-Year Treasury yield at 4.67% remains a key number for markets, as further moves higher could put pressure on equities.
