The ongoing conflict involving Iran has subjected global markets to one of the most turbulent months investors have experienced recently. This volatility began with a sharp escalation in oil prices, setting off a chain reaction that fueled fears of accelerating inflation and a potential global recession.

Market Turmoil: Stocks Plunge Amid Inflation Fears

The immediate fallout saw significant declines across major indices. Both the Dow Jones Industrial Average and the Nasdaq 100 entered official correction territory this week, dropping as much as 10% from recent peaks.

The S&P 500 also felt the pressure, falling nearly 9% from its highs. This performance positions the index for its worst quarterly result since the first half of 2022. These drops reflected a broader risk-off sentiment already present at the start of the year, exacerbated by concerns over the economic outlook.

Five Defining Market Moves of the Month

The market's rollercoaster ride in March was characterized by five specific, dramatic shifts:

  • Oil Price Surge: Brent crude reached as high as $117 a barrel after threats were made against Iranian energy assets, threatening supply stability via the Strait of Hormuz.
  • Stock Correction: Major indices like the Dow and Nasdaq entered correction territory due to economic anxiety.
  • Interest Rate Expectations Plummet: Investors drastically repriced expectations for Federal Reserve rate cuts.
  • Dollar Appreciation: The US Dollar Index climbed significantly as higher rate expectations made dollar-denominated assets more attractive.
  • Gold Price Crash: Safe-haven gold saw a substantial drop as rising yields diminished its appeal.

The Oil Shockwave

Oil benchmarks reacted violently to supply disruption fears stemming from the Middle East conflict. Brent crude, the international standard, is on track for an increase exceeding 60% for March, marking its largest monthly rise on record.

West Texas Intermediate crude's May contracts also climbed as high as $103 a barrel on Monday. Both benchmarks have seen their prices increase by over 50% compared to levels recorded before the Iran conflict began.

Shifting Federal Reserve Expectations

High oil prices introduced significant upward pressure on inflation forecasts, causing investors to adjust their outlook on Federal Reserve policy. The market now anticipates less room for the Fed to cut interest rates.

Consequently, bond yields climbed sharply. The 10-year yield reached as high as 4.4% last week, its highest point since July. This represents an increase of up to 48 basis points from pre-conflict levels.

Dollar Strength and Gold's Retreat

The rise in expected interest rates fueled appreciation in the US dollar. Higher yields attract capital seeking better returns in dollar-denominated assets, pushing the US Dollar Index to around 100 on Tuesday.

This level is approximately 4% higher than before the conflict started, marking the dollar's strongest trade since the beginning of the year. Conversely, gold prices suffered as rising bond yields made non-yielding assets less appealing.

Gold traded around $4,603 an ounce on Tuesday, representing a 13% decline from its pre-war level. This drop was also influenced by the metal being overbought due to speculative retail trading at the start of 2026.
