Few Americans support U.S. military action against Iran, but a majority think it's likely

A February 20-23, 2026 Economist/YouGov poll finds Americans are more likely to oppose than support U.S. military action against Iran: 49% oppose a U.S. attack while 27% support it, though 58% of Republicans favor an attack. Views are more mixed on overthrowing Iran's leader (39% oppose, 29% support), and 58% of respondents think U.S. military action is at least somewhat likely in the next month. Public reaction to President Trump’s handling is negative (48% disapprove vs. 31% approve), and 55% are unsure whether Iranian protests will topple the government, down from 51% 'not sure' and 18% expecting success earlier in February.

Analysis

Market structure: A short-term risk-off tilt is likely to reallocate cash toward defense contractors (LMT, RTX, NOC) and commodity/real-asset proxies (XOM, CVX, GLD) while penalizing travel/transport (JETS, AAL, DAL) and EM_credit (EEM, EMB). Expect bidding power for prime defense OEMs to rise if Congress signals authorizations—order timing could compress supply lead times and raise margins for the next 6–18 months. Oil demand shock risk (supply disruptions through Strait of Hormuz) pushes near-term Brent upside skew; spare capacity from Saudis/US inventories caps sustained >12-month price shocks.

Risk assessment: Tail risks include a significant Iran Strait disruption (WTI>90–100 within 2–6 weeks), cyberattacks on US infrastructure, or widening regional war with asymmetric sanctions; probability low-teens but P&L severe. Immediate horizon (days–weeks): volatility spikes, flight-to-quality; short-term weeks–months: elevated oil/inflation risk; long-term (quarters+) depends on fiscal/military budget responses and persistent supply-chain rerouting. Hidden dependencies: defense suppliers with large Iran-exposure subcontracts or materials from constrained suppliers may miss fulfillment despite headline demand.

Trade implications: Tactical (0–8 weeks) favor 1–2% tactical longs in LMT/RTX, 0.5–1% in GLD and VIX call spreads (30-day) for tail hedges; short 1% JETS or specific airline names Delta (DAL) vs long XOM on oil >$85 trigger. Use options to cap downside: 3-month 25-delta call spreads on XOM/USO sized small (1% AUM) to express oil shock; buy TLT (0.5–1%) only for immediate risk-off (<6 weeks) but reduce if 10y>4.0% persist.

Contrarian angles: Consensus overprices imminent sustained war — historical parallels (2019 tensions) saw brief oil spikes then mean reversion; defense equities often rally into and retrace after headlines. Mispricings: airlines and leisure stocks may oversell by 10–25% on headline risk while long-term travel demand intact; conversely, defense names may already price in a premium—use pair trades (long LMT, short RTX) based on idiosyncratic backlog and valuation gaps. Monitor Brent>95 or VIX>30 as triggers to scale exposure.

Key Decisions for Investors

• Establish a 1.5–2.5% tactical long split between LMT and RTX (ticker LMT, RTX) within 1 week to capture order-flow/defense-spend re-rating; trim back if 3-month returns exceed +15% or if Congress explicitly rejects military authorization.
• Implement a 1% long in GLD and a 30-day VIX call spread (buy 1-month 30-delta calls, sell 1-month 50-delta calls) sized to 1% AUM as immediate hedges; increase allocation by +0.5% if Brent > $90 or VIX > 30.
• Initiate a 1% short of JETS ETF and 0.5% shorts in AAL/DAL as pair hedges against travel demand shock; cover positions if JETS drops >20% or airline CDS widens by +200bps.
• Buy a 3-month 25-delta call spread on XOM (or USO) sized 1% AUM to express an oil-disruption scenario; add another 1% if Brent breaches $95 for more than 3 trading days.
• Add 0.5–1% duration hedge with TLT for immediate (0–6 week) flight-to-quality; unwind if 10-year Treasury yield rises above 4.00% for more than 5 trading days to avoid inflation-driven losses.
