Key Market Drivers and Macro Environment

1. Oil price surge and stalled U.S.-Iran negotiations

International oil prices spiked as peace negotiations between the U.S. and Iran hit a standstill. President Trump’s rejection of Iran’s latest proposal has increased the likelihood of a protracted conflict, fueling concerns over rising energy costs and reigniting inflation. The oil surge on May 12 was a direct catalyst for cooling the Wall Street rally.

2. Persistent inflation and the wait for April CPI

According to a report from Schwab released before the market opened on May 12, stubborn inflationary pressures kept stocks under downward pressure from the start of the session. With the April Consumer Price Index (CPI) and Producer Price Index (PPI) due this week, signals of re-accelerating inflation could dampen hopes for Federal Reserve rate cuts.

3. U.S.-China summit expectations vs. AI rally fatigue

Expectations for a meeting between President Trump and President Xi Jinping on Monday, May 11, provided a slight boost to the indices; however, the momentum for tech stocks based on AI optimism is fading as the late-earnings season progresses. While the AI frenzy had been supporting gains, the jump in crude oil prices sparked inflation concerns that suppressed buying sentiment across the board.
