Oil Shock Reshapes S&P 500's Ties to Bonds Amid Iran Tensions

Energy markets are increasingly dictating the S&P 500's daily rhythm as the Iran conflict keeps oil prices elevated and investor nerves frayed. The traditional stock-bond relationship is being tested, with crude now acting as the dominant variable pulling equity sentiment in either direction.

This shift matters for S&P 500 positioning because higher energy costs threaten margin compression across consumer and industrial sectors just as markets brace for a pivotal Federal Reserve decision. Index-level volatility could stay elevated if oil continues to override rate expectations as the primary market driver.

With safe-haven flows and commodity price swings now intertwined, traders tracking the S&P 500 need to weigh geopolitical risk premiums alongside standard technical levels this week.
