Markets In Focus: The Week That Was and What’s On Tap Week-Ending 3/20/2026
THE WEEK THAT WAS
US equity markets navigated a challenging week ending March 20, 2026, amid persistent geopolitical tensions, elevated energy volatility, and mixed signals from monetary policy. The S&P 500 declined approximately –1.9% for the week, reflecting broad-based pressure from macro uncertainties. The Nasdaq Composite fell more sharply, down around –2.0% (with late-week selling accelerating losses), while the Russell 2000 dropped 1.7%. The Invesco S&P 500 Equal Weight ETF (RSP) outperformed large-cap benchmarks modestly, declining –1.6%.
Primary drivers included the FOMC’s March 18 decision to maintain the federal funds rate target range at 3.5–3.75%, accompanied by a hawkish tone that emphasized lingering inflation risks and geopolitical factors limiting near-term flexibility. Oil markets remained volatile and elevated, with prices surging on supply concerns tied to the ongoing Iran conflict, including threats and disruptions around the Strait of Hormuz that amplified stagflationary pressures and weighed on risk assets.
AI-themed equities provided pockets of resilience. Nvidia’s GTC conference delivered key announcements on the Vera Rubin platform—featuring advanced chips and systems optimized for agentic AI—along with previews of the future Feynman architecture and infrastructure enhancements, sustaining momentum in the sector. Micron ($MU) reported fiscal Q2 results that significantly exceeded expectations, with record revenue of $23.86 billion driven by robust AI-related memory demand and strong guidance for the next quarter.
Sector performance reflected these dynamics: Energy led amid oil strength, while Technology and Financials lagged, facing headwinds from macro caution and rotation pressures. Broader volatility persisted, with inflation signals and small-cap outperformance trends adding context to the week’s uneven tone.
As markets head into the weekend, attention is focused squarely on the ongoing geopolitical developments and any fresh data on energy flows in the coming week.
THE WEEK AHEAD
As the US-Israel-Iran conflict enters its third week, the overriding influence on capital markets remains the sharp escalation in energy prices driven by supply disruptions through the Strait of Hormuz. Brent crude has stabilized above $100 per barrel after earlier spikes toward $120, sustaining elevated volatility and reinforcing concerns over persistent inflation pressures. This dynamic introduces a meaningful risk of higher-for-longer interest rates, as the Federal Reserve may exercise added caution in any policy easing amid renewed commodity-driven price impulses, potentially tempering equity risk appetite and contributing to bouts of market turbulence, particularly in growth-sensitive segments.
Against this backdrop, the domestic economic and earnings calendars appear notably light for March 23–27. Key releases include Monday’s Chicago Fed National Activity Index for February, offering a gauge of broader economic momentum, and Tuesday’s ADP Employment Change, which could provide an early read on labor market resilience. Construction Spending data midweek may offer modest insight into fixed investment trends. Corporate earnings remain sparse, with limited major reports expected to move the needle broadly. Overall, absent fresh catalysts, the conflict’s energy shock is poised to dominate sentiment, sustaining caution across equities while exerting upward pressure on rates in the fixed income arena.
