Markets endured another turbulent week as rapid-fire developments in the Middle East conflict whipsawed investor sentiment, leaving stocks lower for a fourth consecutive week despite brief stretches of optimism early on.
The Numbers
- S&P 500: −1.89%
- Nasdaq: −2.07%
- Dow Jones Industrial Average: −2.11%
- MSCI EAFE: −2.01%
For the first time in several weeks, U.S. and international markets fell in near-lockstep — a sign that the conflict’s economic implications are being felt broadly across global equity markets, not just domestically.

What Happened
Monday–Tuesday: Cautious Rebound Stocks opened the week higher as oil prices eased and investors saw potential value in beaten-down names. Reports that a coalition of countries was considering joining efforts to escort tankers out of the Persian Gulf provided an additional lift. Markets held their footing Tuesday as investors awaited further conflict developments, largely looking past fresh attacks on tanker ships near the Strait of Hormuz — the chokepoint through which roughly one in five barrels of the world’s exported oil passes.
Wednesday: Fed Holds, Inflation Bites The Federal Reserve held rates steady at its 3.50%–3.75% target range, as expected. But the accompanying tone was less reassuring than markets had hoped. Fed Chair Powell acknowledged that inflation was not declining as quickly as policymakers had projected. Separately, a warmer-than-expected wholesale inflation reading added to the pressure, and stocks resumed their decline.
Thursday: Slide Continues, Late Rally Cushions Stocks fell again Thursday as optimism about a near-term reopening of the Strait of Hormuz began to fade. A late-session relief rally helped limit the day’s losses but did little to change the week’s direction.
Friday: Iran Declares Force Majeure Stocks opened lower and briefly stabilized midday — before Iran declared force majeure on all foreign-owned oilfields, a significant escalation that sent markets lower again into the close. It was a fitting end to a week defined by headlines arriving faster than investors could process them.
The Fed’s Message This Week While the rate decision itself was widely anticipated, the Fed’s tone deserves attention. Chair Powell’s acknowledgment that inflation is proving more stubborn than projected — combined with the so-called dot plot showing a possible rate adjustment before year-end — signals that the Fed is navigating a genuinely difficult environment. Policymakers are contending with slowing growth, a labor market showing cracks, and now an energy price shock that could push inflation higher before it moves lower. The Fed appears to be holding its ground for now, but the margin for error is narrowing.
What We’re Watching
Iran’s Force Majeure Declaration Friday’s late-session escalation is the most significant development to monitor heading into this week. A force majeure on foreign-owned oilfields could meaningfully reduce global oil supply and keep energy prices elevated — deepening the inflationary pressure the Fed is already struggling to contain.
Four Down Weeks U.S. equities have now declined four consecutive weeks. While that alone doesn’t signal a sustained bear market, the combination of geopolitical shock, sticky inflation, slowing growth, and a Fed with limited room to maneuver creates a more challenging environment than markets faced entering the year.
A Quieter Data Week This week’s economic calendar is relatively light, with Friday’s final Consumer Sentiment reading the most watched release. That puts the Middle East squarely back in the driver’s seat as the primary market catalyst.
