What Moved Markets

• Trump Threatens Iranian Energy Infrastructure: Fresh threats from President Trump directed at Iran's energy infrastructure have cooled market confidence, with oil prices surging in response and fanning fears of persistent inflation. The move represents a potential escalation in the U.S.-Iran conflict that has already rattled markets for weeks.

• Fed Holds Rates, No Cuts Expected Before 2027: The Federal Reserve held its benchmark rate steady at 3.50%–3.75% at its March 18 meeting, and market pricing has now shifted to reflect no rate cuts before 2027. Fed Chair Jerome Powell's comments drew attention to the threat of persistent inflation, partly tied to uncertainty stemming from the Iran war, sending stocks to session lows following the decision.

• Four-Week Losing Streak Deepens: Major indices are on track for a fourth consecutive week of losses and are now technically in oversold territory, as the U.S.-Iran conflict continues to dominate market psychology. The S&P 500 has lost more than 3% in 2026 and is trading at four-month lows, with traders broadly adopting defensive postures.

Sector Scorecard

Granular sector-level performance data for March 23, 2026 was not available at time of publication. Based on available context from the week's trading:

• Technology: Under pressure — tech stocks have been a significant drag as inflation fears and rate-hold signals weigh on growth-oriented sectors. The Nasdaq has tracked losses alongside broader indices.

• Energy: Outperforming — surging oil prices driven by U.S.-Iran tensions have broadly benefited energy sector names, with WTI briefly nearing $120/barrel in recent sessions.

• Utilities: Showing relative resilience — power-hungry data center demand has continued to support utility sector performance even as broader markets decline.

• Financials: Broadly weak — rate-hold expectations and economic uncertainty have pressured financial stocks, which tend to benefit from a steeper rate path.

Notable Movers

Specific individual stock data for March 23, 2026 was not available in research results at time of publication. The following reflects the broader context from the prior trading week:

What to Watch Next

• Week of March 23–27 Market Action: CNBC's weekly outlook flags that stocks have been "largely calm" since the start of the U.S.-Iran war, but warns that the latest Trump threats against Iranian energy infrastructure "could signal a turn for the worse." Traders will be watching closely for any military or diplomatic developments that could whipsaw equity markets — particularly in energy and defense sectors.

• Inflation Data and Fed Speakers: With the Fed on hold and market pricing ruling out cuts until 2027, any incoming economic data — particularly inflation prints — will be closely scrutinized. Hawkish surprises could accelerate the selloff in rate-sensitive sectors, while softer readings may offer temporary relief to an oversold market.
