U.S. stock futures moved higher on Tuesday, pointing to a positive start on Wall Street after the major averages finished the previous session mostly lower.

A renewed decline in crude oil prices helped improve market sentiment, with traders reassessing the potential impact of Washington’s latest economic measures against Iran. Oil had already fallen by more than 2% on Monday, ending a six-session winning streak, before U.S. crude futures extended the retreat by more than 3% on Tuesday.

The sharp reversal in energy prices has also helped bring Treasury yields down from recent highs, providing additional support for equity valuations.

Washington Unveils New Iran Sanctions Campaign

The latest move in oil followed the U.S. Treasury Department’s announcement of “Operation Economic Outcast,” which it described as an unprecedented, government-wide economic campaign targeting Iran and its “enablers.”

The U.S. imposed sanctions on nearly 60 entities, individuals and vessels that authorities said “enable the Iranian regime’s recklessness.”

However, the measures stopped short of immediately applying secondary sanctions to countries maintaining commercial relationships with Iran. That appeared to reassure commodity markets, which had been preparing for potentially tougher action capable of disrupting global oil flows.

With crude prices retreating, Treasury yields also continued to ease, helping strengthen the case for an initially positive session on Wall Street.

Nvidia and Inflation Data Remain Key Market Tests

Investors may nevertheless be reluctant to make aggressive moves ahead of several major events later this week.

Nvidia (NASDAQ:NVDA) is due to release its second-quarter results after Wednesday’s closing bell, making the report an important test of investor confidence in artificial intelligence and semiconductor spending.

Closely watched U.S. inflation figures are also approaching, while attention will turn to the Jackson Hole economic symposium and Federal Reserve Chair Kevin Warsh’s remarks on Friday.

These events could influence expectations for monetary policy and determine whether the recent improvement in risk appetite can be sustained.

Technology Weakness Weighs on Monday’s Session

Wall Street endured a mixed session on Monday, with stocks recovering from their early lows but generally remaining under pressure.

The Nasdaq fell 200.26 points, or 0.8%, to 25,980.19, leaving the technology-heavy index at its lowest closing level in three weeks.

The S&P 500 declined 21.51 points, or 0.3%, to 7,652.86.

The Dow Jones Industrial Average bucked the broader trend, advancing 140.15 points, or 0.3%, to 53,417.16 as gains in Visa (NYSE:V), Walmart (NYSE:WMT) and Disney (NYSE:DIS) provided support.

Nvidia Slides Ahead of Quarterly Results

Technology shares were responsible for much of Monday’s weakness, with semiconductor stocks suffering particularly heavy selling.

The Philadelphia Semiconductor Index dropped 2.7%, while Nvidia (NASDAQ:NVDA) lost 2.9% as investors positioned themselves ahead of the AI chipmaker’s earnings announcement.

Computer hardware and networking stocks also came under pressure. Energy shares weakened alongside crude oil, although overall market activity remained relatively subdued as traders waited for the week’s major catalysts.

Investors Look to Warsh for Clues on Fed Strategy

Federal Reserve Chair Kevin Warsh’s Jackson Hole appearance on Friday is expected to attract significant attention as markets assess the outlook for inflation and interest rates.

“[Fed Chair Kevin] Warsh is scheduled to deliver keynote remarks on Friday, and markets will be looking for greater clarity on both his assessment of inflation and the broader “regime change” he has advocated at the Fed,” said Daniela Hathorn, Senior Market Analyst at Capital.com.

She added, “He has been reluctant to provide conventional forward guidance, meaning the speech may focus more heavily on the Fed’s reaction function and longer-term philosophy than explicitly signaling what policymakers will do in September.”

With few major U.S. economic releases immediately available, some investors may remain cautious until Wednesday’s consumer inflation figures provide a clearer picture of price pressures.

For now, the combination of falling crude prices, lower Treasury yields and stronger futures is creating a more constructive backdrop for Wall Street, although Nvidia, inflation and Jackson Hole could determine the market’s next major move.
