Week in Review
Financial markets endured one of their most turbulent weeks of 2026, as a sudden and dramatic escalation of geopolitical conflict in the Middle East sent crude oil prices surging more than 35% and rattled investor confidence across virtually every asset class. The S&P 500 fell 2.02% for the week, pushing the index into negative territory for the year at approximately -1.5%. The Dow Jones Industrial Average posted its worst weekly performance in nearly a year, shedding roughly 2.5% and closing Friday at 47,501.55 after a single-session loss of 453 points. The Nasdaq Composite declined 1.24% for the week, holding up relatively better than its peers as technology stocks partially offset broader market weakness.
The week's dominant narrative was the rapid escalation of the U.S.-Israel military campaign against Iran, which began over the prior weekend with joint strikes targeting senior Iranian leadership and key military infrastructure. Iran's retaliatory response and threats to restrict tanker traffic through the Strait of Hormuz — the critical chokepoint through which more than 14 million barrels of crude oil pass daily — sent energy markets into a historic frenzy. West Texas Intermediate (WTI) crude surged from approximately $67 per barrel at the start of the week to above $91 by Friday's close, a gain of more than 35% in five trading sessions.
Compounding the geopolitical shock, Friday's February jobs report delivered a deeply disappointing reading on the U.S. labor market. Nonfarm payrolls fell by 92,000 — far below expectations for a modest gain — while the unemployment rate ticked up to 4.4%. The combination of rising energy prices, weakening employment data, and persistent geopolitical uncertainty created a challenging backdrop for risk assets, with the broad Morningstar U.S. Market Index declining 2.18% on the week.
Top Stories of the Week
1. Oil Surges Past $90 as Iran Conflict Threatens Strait of Hormuz
The U.S.-Israel military campaign against Iran dominated global headlines and financial markets throughout the week. Joint operations launched over the prior weekend triggered immediate Iranian retaliation and raised fears of a prolonged regional conflict with severe consequences for global energy supplies. Qatar's energy minister warned that Gulf oil producers could halt shipments entirely if the conflict expands, while Iran threatened to target tankers attempting to transit the Strait of Hormuz. By Friday, WTI crude had broken decisively above $90 per barrel — a level not seen in years — while Brent crude futures climbed to fresh 52-week highs above $89. The U.S. Development Finance Corporation announced a $20 billion reinsurance facility in an effort to keep oil tankers moving through the strait, underscoring the severity of the supply disruption risk. Analysts at Citigroup raised price targets across major integrated oil producers including Chevron and Exxon Mobil, while some projections warned that prices could reach $150 per barrel if the Strait of Hormuz is effectively closed.
Investment implications: Sustained oil prices above $90 per barrel introduce a significant new inflationary variable into the macro environment. Investors should consider increasing exposure to integrated energy companies and oilfield services firms while reducing positions in fuel-cost-sensitive sectors such as airlines, cruise lines, and logistics companies. The energy sector's outperformance this week reinforces the case for maintaining or increasing energy allocations as a portfolio hedge against geopolitical risk.
2. AI Infrastructure Momentum Anchors Technology Amid Volatility
Despite the macro turbulence, artificial intelligence infrastructure and semiconductor companies provided a stabilizing force within equity markets. NVIDIA shares rebounded after reports that the company plans to introduce a new inference processor incorporating technology from startup Groq, designed to accelerate AI workloads for large-scale deployments. Broadcom delivered strong earnings and projected that its AI-related revenue could exceed $100 billion by fiscal year 2027, driven by surging demand from hyperscale data center customers. Marvell Technology also raised its long-term revenue projections, citing strong demand for networking and custom silicon components used in AI clusters. Enterprise software showed signs of stabilization, with the iShares Expanded Tech-Software ETF climbing throughout the week as companies like ServiceNow, Intuit, and Workday posted solid gains. Cybersecurity firm CrowdStrike delivered earnings that reinforced the view that AI is more likely to enhance security platforms than displace them, while reports of Anthropic's annualized revenue surpassing $19 billion highlighted the extraordinary scale of growth in the generative AI ecosystem.
Investment implications: Persistent capital spending on AI infrastructure continues to anchor technology leadership within equity markets. The sector's relative resilience during a week of broad market weakness suggests that AI-related demand remains a structural rather than cyclical driver of returns. Investors with long-term horizons may view volatility-driven pullbacks in quality semiconductor and AI software names as potential accumulation opportunities.
3. BlackRock Limits Withdrawals from $26 Billion Private Credit Fund
In a development that rattled credit markets on Friday, BlackRock — the world's largest asset manager — announced it was capping withdrawals from its $26 billion HPS Corporate Lending Fund at 5% after a surge in redemption requests. The fund, which invests in private credit instruments, had seen client requests for redemptions spike amid rising concerns about the broader $2 trillion private credit market. BlackRock shares fell more than 7% on the news, marking the stock's worst single-session decline since April. The development drew comparisons to similar situations faced by rival Blackstone, which took the opposite approach by not limiting withdrawals from its comparable vehicle. The episode raised broader questions about liquidity management in private credit markets, particularly at a time when rising interest rates and geopolitical uncertainty are increasing stress across credit portfolios.
Investment implications: The BlackRock private credit fund episode serves as a reminder of the liquidity risks embedded in alternative investment vehicles. Investors in private credit, real estate, and other illiquid alternatives should carefully review redemption terms and gate provisions. The widening of investment-grade corporate bond spreads this week suggests that credit market stress may be broadening beyond private markets.
4. Weak February Jobs Report Complicates Fed's Policy Path
Friday's Bureau of Labor Statistics report showed nonfarm payrolls fell by 92,000 in February, a sharp reversal from January's downwardly revised gain of 126,000 and far below the consensus expectation for a modest gain of approximately 50,000. Prior months' figures were revised lower by a combined 69,000 jobs. The unemployment rate rose to 4.4% from 4.3%. However, wage growth remained firm, with average hourly earnings rising 0.4% for the month and 3.8% year-over-year — both slightly above expectations. This combination of weakening job creation alongside persistent wage inflation presents the Federal Reserve with a difficult policy dilemma: slower employment growth might normally support rate cuts, but rising wages and surging oil prices could keep inflation elevated well above the 2% target.
Investment implications: The stagflationary undertones of the current data environment — slowing growth combined with persistent inflation — represent a challenging backdrop for both equities and bonds. Investors should consider tilting fixed-income allocations toward shorter-duration Treasuries and higher-quality corporate bonds, as the Fed is unlikely to provide the policy relief that markets had previously anticipated for the first half of 2026.
Sector Performance Analysis
The week's sector performance reflected a clear bifurcation between commodity-sensitive and geopolitically-driven winners on one hand, and fuel-cost-exposed and economically-sensitive losers on the other. According to Morningstar data, the energy sector was the only S&P 500 sector to post a positive return for the week, gaining approximately 1.3%, as crude oil's historic surge lifted integrated producers, refiners, and oilfield services companies alike. Defense and aerospace names also outperformed, with Northrop Grumman, Raytheon Technologies, and Axon posting strong gains on expectations of increased military spending. The technology sector, while broadly negative, held up relatively well with a decline of only 0.44%, supported by the AI infrastructure momentum described above.
At the opposite end of the performance spectrum, basic materials was the worst-performing sector, declining 7.37%, followed by industrials at -5.01%. The materials sector was hit by a combination of global growth concerns and a stronger U.S. dollar, which rose 1.4% for the week — its best weekly gain since August 2025 — as international investors sought safety in dollar-denominated assets. Consumer discretionary stocks suffered heavily from the dual pressures of higher fuel costs and weakening consumer confidence, with cruise operators Carnival and Norwegian Cruise Line each losing approximately 18-19% on the week. Airline stocks including United Airlines, Delta, and Southwest sold off sharply on fuel cost concerns. The Russell 2000 small-cap index underperformed significantly, declining approximately 4.51% as smaller companies face disproportionate exposure to higher energy costs and tighter credit conditions.
Investment implications: The current sector rotation toward energy and defense at the expense of consumer discretionary, industrials, and basic materials reflects a classic geopolitical risk-premium repricing. Investors may consider rotating toward energy, defense, and utilities — sectors that historically outperform during periods of elevated geopolitical tension and rising commodity prices — while reducing exposure to travel, transportation, and consumer-facing businesses with high fuel cost sensitivity.
Economic & Fed Developments
Beyond the headline jobs report, the week's economic data painted a mixed picture that complicates the Federal Reserve's policy calculus. The February ISM Manufacturing Index registered 52.4%, slightly above expectations and remaining in expansion territory, though the report's Prices Paid component accelerated sharply — a concerning signal given the simultaneous surge in energy costs. The ISM Non-Manufacturing Index rose to 56.1, comfortably above consensus and signaling continued expansion in the services sector. Initial jobless claims remained historically low at 213,000, suggesting that while hiring has stalled, layoffs have not yet accelerated significantly.
Federal Reserve officials were notably cautious in their public communications this week. Cleveland Fed President Beth Hammack stated that the central bank must remain focused on lowering inflation and that it was unclear what impact surging oil prices would have on the policy outlook. Market expectations for the next rate cut have been pushed firmly into the second half of 2026, with year-end rate-cut expectations falling to approximately 40 basis points from 60 basis points just weeks ago. The 10-year Treasury yield rose to 4.15% from 3.97% the prior week, reflecting both the inflation concerns embedded in higher oil prices and reduced expectations for near-term Fed easing. The American Bankers Association's Economic Advisory Committee noted that inflation is expected to remain above the Fed's 2% target for the next eight quarters, with each $10 increase in oil prices estimated to add approximately 0.1% to core inflation.
Looking Ahead
The week ahead promises to be equally consequential for markets, with a slate of potentially market-moving economic data releases and ongoing geopolitical developments demanding close attention. The most significant data point will be Wednesday's February Consumer Price Index (CPI) report, which is expected to show the annual inflation rate edging up to approximately 2.5% from 2.4% in January. Given the surge in energy prices that occurred during the final days of February and accelerated dramatically in the first week of March, any upside surprise in the CPI reading could further dampen expectations for Fed rate cuts and pressure equity valuations.
Also on the calendar are February Existing Home Sales on Tuesday, Housing Starts and Initial Unemployment Insurance Claims on Thursday, and January Durable Orders along with Q4 GDP and January Personal Income and Outlays data on Friday. Earnings reports from Oracle on Tuesday and Adobe on Thursday will provide additional insight into the health of enterprise technology spending. Geopolitical developments in the Middle East will continue to be the dominant market driver, with any escalation or de-escalation in the Iran conflict likely to produce outsized moves in oil prices, defense stocks, and safe-haven assets. Investors should brace for continued volatility and consider maintaining defensive positioning until there is greater clarity on both the geopolitical and inflationary fronts.
