Early phase of the US–Israel–Iran conflict triggers risk-off moves, volatility in SPY, and demand for defensive ETFs.

The early phase of the renewed US–Israel–Iran conflict, which erupted in March 2026, continues to significantly influence global financial markets, driving a pronounced risk-off sentiment, heightened volatility in the SPDR S&P 500 ETF Trust (SPY), and robust demand for defensive and thematic ETFs. While initial market reactions were marked by sharp selloffs and oil price spikes, recent weeks have brought new dynamics shaped by evolving geopolitical developments, Federal Reserve policy outlooks, and sector rotations that underscore the complexity of navigating today’s investment landscape.

Renewed Geopolitical Tensions Fuel Market Volatility and Risk-Off Flows

The flare-up of hostilities in early March 2026, triggered by Iran’s claim of responsibility for a tanker attack in the Gulf, dramatically intensified fears over disruptions to key oil transit routes. This event pushed WTI crude oil prices above $95 per barrel, a level not seen since mid-2024, reigniting inflationary concerns within already fragile stagflationary conditions. The immediate market impact was severe:

• The Dow Jones Industrial Average plunged roughly 800 points on March 6, reflecting acute investor risk aversion amid uncertainty regarding the conflict’s trajectory and its broader economic implications.
• The SPY ETF experienced significant intraday swings, breaching critical technical supports such as the 6,792 level and the 4-hour 200-period EMA. This volatility was amplified not only by headline geopolitical risk but also by complex options market mechanics, including gamma hedging and hedged dispersion strategies, which exacerbated price swings.
• Idiosyncratic movements in high-profile large-cap stocks like BlackRock (BLK) further contributed to SPY’s volatility, illustrating how liquidity-sensitive names can magnify index-level nervousness during periods of stress.

Despite intermittent diplomatic efforts — notably the initial US–Iran talks starting March 4 — market participants remain on edge, as the conflict’s persistence continues to inject uncertainty into global markets.

Energy Sector Rotation Intensifies: Chevron Nears Record Highs

Among the most notable market developments is a decisive rotation into the energy sector, with Chevron emerging as a clear leader. Chevron’s shares surged to approximately $190, approaching levels last seen during the 2022 energy crisis. This rally is emblematic of investors’ strategic shift toward energy assets for several reasons:

• Geopolitical risk premiums: Sustained Middle East tensions and concerns over supply chain disruptions have underpinned expectations for elevated oil prices.
• Inflation hedging and structural resilience: Energy companies benefit from increased domestic production, governmental emphasis on energy security, and relative insulation from supply chain shocks compared to other sectors.
• This rotation is not merely defensive but reflects a tactical repositioning, where energy stocks and ETFs serve as both inflation hedges and growth plays aligned with the new geopolitical realities.

Market analysts emphasize that Chevron’s leadership validates the importance of maintaining meaningful energy exposure within diversified portfolios, especially as oil prices remain volatile but elevated.

Defensive and Thematic Sectors Continue to Attract Capital

In parallel with the energy rotation, investors have gravitated toward sectors traditionally seen as safe havens, as well as thematic areas poised for secular growth or benefiting from government spending initiatives:

• Consumer staples, healthcare (XLV), and utilities sectors have outperformed amid heightened uncertainty, drawing inflows from investors prioritizing capital preservation.
• Defense ETFs and stocks have gained prominence due to ongoing military tensions and expectations of increased defense budgets. Defense contractors are viewed as beneficiaries of sustained government spending.
• Infrastructure and industrial technology sectors continue to attract attention, supported by reshoring trends and government investments aimed at securing critical supply chains and fostering technological autonomy.
• The technology sector narrative has sharpened toward pragmatic leadership, with a focus on mission-critical areas such as AI, automation, and defense-linked technologies rather than speculative growth names vulnerable to shocks.

JPMorgan analyst Mislav Matejka encapsulates this approach, advocating a “buy-the-dip” strategy predicated on the view that while oil prices may stay elevated, outright supply disruptions are likely to be contained. This thesis supports tactical entry points into quality sectors amid volatility.

Federal Reserve Policy Developments and Macro Overlay

Recent weeks have also seen important macroeconomic updates shaping market sentiment:

• The market is bracing for what some analysts call a “Federal Reserve double whammy”, an anticipated period around two months ahead where the Fed may deliver a pivotal policy stance or leadership change that could mark a market inflection point. This adds an additional layer of uncertainty to an already complex environment.
• Treasury Secretary Janet Yellen’s recent statements have reinforced cautious optimism, highlighting the Fed’s readiness to respond decisively to inflation dynamics. This messaging has helped moderate fears of aggressive monetary tightening, supporting risk sentiment during intermittent relief rallies.
• Weekly market wraps underscore the leadership of energy and defense stocks, reinforcing the sector rotations driven by geopolitical and policy considerations.

Improved options market liquidity and dealer gamma hedging have at times helped stabilize the SPY within tradable ranges, mitigating the potential for deeper selloffs and allowing investors to tactically adjust portfolios.

ETF Flows and Market Structure: Defensive, Energy, and Commodity Plays

The conflict-driven market environment has catalyzed distinct shifts in ETF demand and sector preferences:

• Defensive ETFs tracking consumer staples, healthcare, and utilities have seen increased inflows, reflecting investor prioritization of capital preservation.
• Energy-focused ETFs remain volatile but compelling as vehicles to capture geopolitical risk premiums amid fluctuating oil prices.
• Defense ETFs continue to attract interest, supported by sustained military tensions and anticipated government budget increases.
• Commodity-linked ETFs, especially gold and silver, have functioned as inflation hedges. Gold recently peaked before a moderate pullback, indicating fluctuating safe-haven demand.
• Technology ETFs concentrated on AI, automation, and defense-related applications are favored over more speculative growth ETFs vulnerable to shocks, reflecting a more pragmatic sector outlook.

Given the evolving geopolitical news, central bank policy shifts, and nuanced options market dynamics, active, sector-aware portfolio management remains imperative. Investors must balance defensive resilience with selective risk-taking to navigate the turbulence effectively.

Summary and Forward Outlook

The March 2026 escalation in the US–Israel–Iran conflict has injected significant volatility and risk aversion into equity markets, with sharp oil price spikes and inflation fears amplifying selloffs. The SPY ETF’s breach of technical supports, complicated by options market microstructure effects and idiosyncratic large-cap moves, has made for a challenging trading environment.

Chevron’s near-record share price epitomizes the energy sector rotation, reinforcing the strategic value of energy exposure amid ongoing Middle Eastern tensions. Defensive sectors such as consumer staples, healthcare, utilities, and thematic plays in defense, infrastructure, and pragmatic technology continue to provide refuge and growth opportunities.

Intermittent diplomatic engagements and improved options market liquidity have offered temporary relief, but investors remain vigilant amid persistent geopolitical uncertainty and stagflationary pressures. The consensus among analysts favors buy-the-dip approaches with disciplined risk management, emphasizing tactical flexibility and active portfolio adjustments.

Going forward, market participants should closely monitor:

• Geopolitical developments for potential escalation or resolution signals
• Inflation-sensitive sector exposures and commodity-linked assets
• Tactical sector rotations benefiting from reshoring, defense spending, and energy security imperatives
• Options market dynamics that may amplify volatility or create attractive entry points

Successfully navigating this complex landscape requires balancing defensive positioning with selective risk-taking, a strategy well suited to the multifaceted geopolitical and macroeconomic realities shaping 2026.
