TLDR
- Major U.S. indexes are heading toward their fourth consecutive week of declining performance
- The Dow’s current losing streak represents its longest downturn since early 2023
- Crude oil prices continue trading at elevated levels, with Brent approaching $108 per barrel
- Market anxiety intensified following reports of potential U.S. military action targeting Iran’s crucial oil export terminal
- Cryptocurrency markets mirrored stock weakness, with Bitcoin and XRP posting notable declines
American equity markets experienced another session of losses on Friday, March 20, extending what has become a challenging four-week period for investors. The persistent decline has been fueled primarily by surging energy costs and heightened geopolitical tensions stemming from the Iran crisis.
The Dow Jones Industrial Average retreated approximately 300 points during Friday’s trading, representing a decline of roughly 0.7%. The S&P 500 shed close to 1%, while the tech-heavy Nasdaq Composite experienced a steeper fall of approximately 1.3%.
Should the Dow complete this fourth consecutive week in negative territory, it would represent the index’s most extended period of continuous losses since the streak ending February 24, 2023. The S&P 500’s last four-week consecutive decline occurred in March 2025.
The Nasdaq has already endured a five-week losing period earlier in the current year and is once more flirting with correction territory, joining the Dow in this precarious position.
Investor anxiety has remained elevated since joint U.S.-Israel military operations targeting Iran commenced on February 28. Energy commodity prices have maintained their upward trajectory throughout this period, creating a significant headwind for market confidence.
Brent crude contracts traded near the $108 per barrel threshold on Friday, while West Texas Intermediate futures circled around $96. Both benchmark grades exhibited volatility throughout the trading day, oscillating between positive and negative territory.
Market nerves were further frayed by a Friday report from Axios detailing that the Trump administration is evaluating strategic options that could include either occupying or establishing a blockade around Kharg Island, which serves as Iran’s primary oil export facility. This potential action is being considered as leverage to compel Tehran to reopen the Strait of Hormuz for commercial tanker passage.
Iran continued launching attacks against neighboring Persian Gulf nations on Friday. Market observers have cautioned that existing infrastructure damage throughout the region will likely sustain elevated oil prices for an extended period.
Why Oil Prices Are Driving Markets
Paul Hickey, co-founder of Bespoke Investment Group, observed that Friday’s market trajectory would “depend almost entirely on the price of oil.” In the absence of significant economic releases or corporate earnings reports, geopolitical developments remained the primary catalyst for market movements.
Friday’s session coincided with a quarterly triple witching event, during which stock options, stock index futures, and stock index options simultaneously reach expiration. These occasions typically generate amplified trading volatility.
David Laut, chief investment officer at Kerux Financial, noted that the triple witching phenomenon could be intensified by the market’s already fragile condition entering the session.
The S&P 500 concluded Thursday’s trading beneath its 200-day moving average, a critical threshold monitored by technical market analysts. Frank Cappelleri of CappThesis explained that while a single close below this technical level doesn’t necessarily signal continued deterioration, it does represent an inflection point where traders begin evaluating potential buying opportunities.
Crypto Also Takes a Hit
Equity markets weren’t alone in experiencing a difficult week. Bitcoin and XRP both recorded losses, contributing to broader weakness across digital asset markets. The Securities and Exchange Commission also endorsed a Nasdaq initiative to tokenize securities, a development that generated interest within the cryptocurrency community but failed to provide meaningful price support during the session.
Both the Dow and Nasdaq concluded the week hovering near correction levels, with market participants closely monitoring every development emerging from the Middle East for signals about future direction.
