Monday looked like a turning point for crude. Brent crude futures settled $8.66, or 7.63%, lower at $104.77 a barrel after Trump signaled more time for Iran diplomacy and Iranian state media reported that Tehran had granted the government authority to pursue peace negotiations. Airlines ripped higher on the news. Energy stocks dumped. The market spent an entire session pricing the war.
Then overnight, the Wall Street Journal reported a US military strike on Iran’s Qeshm Island, right at the mouth of the Strait of Hormuz. Iranian state media reported explosions being heard on Qeshm Island.
By Tuesday morning, Brent crude was up about 1.7% at about $106.58 per barrel, while West Texas Intermediate had gained about 1.7% to around $98.10. The peace-talk premium that came out Monday went back in overnight.
Energy: Monday’s sellers have a problem
The S&P 500 energy index fell 2.1% on Monday as crude declined following the diplomatic headlines. ExxonMobil and Chevron fell 2.4% and 2%, respectively. Both now open Tuesday facing an oil price that has erased the entirety of Monday’s drop and then some. Traders who sold XOM and CVX into the peace-talk slide now face a crude market that is back above where it traded Friday. Watch whether either stock reclaims its pre-Monday close. If Brent holds above $106, the case for further recovery in energy names is straightforward.
Airlines: Monday’s winners give some back
The Monday airline trade was clean: oil falls, fuel costs fall, loss-heavy carriers benefit most. JetBlue jumped about 11%, American Airlines gained about 5%, and Delta rose about 5%. JetBlue said its average fuel price in Q3 2026 was $3.91 per gallon, 57% higher than the prior year period, so the relief was real and immediate for the balance sheet.
Tuesday reverses the logic. Cheaper fuel helps airlines near breakeven most, and JetBlue’s Q4 guidance assumes fuel at $4.64 a gallon. With Brent back above $106, that guidance assumption looks tight again. JBLU, AAL, DAL, and UAL all face opening pressure. The stocks most leveraged to Monday’s drop are the same ones most exposed to Tuesday’s reversal.
Tankers: the other side of the trade
When key shipping routes stay contested, tanker operators can benefit from rerouting and longer voyages. Disruptions that force ships to take longer routes can reduce effective tanker availability and lift daily charter rates. Frontline (FRO) is one of the largest publicly traded crude-tanker operators, so it is a direct expression of that trade. A Hormuz that stays disrupted is structurally bullish for FRO; a genuine peace deal is the risk that collapses the position.
What to watch
- Brent above $107: confirms war premium is fully rebuilt; energy names extend, airlines stay under pressure.
- Iran response to the Qeshm strike: any retaliation against commercial shipping pushes oil higher and pressures airlines further.
- Diplomatic track: the Qeshm strike is described by the Wall Street Journal as part of a series of limited strikes carried out in recent weeks. If that framing holds, markets may treat it as noise rather than escalation.
- Midterm election results: post-midterm positioning may shift quickly depending on the outcome.
The session sets up as a direct reversal of Monday. Oil up, airlines down, energy names higher. The key variable is whether Iran treats Qeshm as a provocation or the US maintains the low-profile, defensive framing. That answer will arrive before the close.
