Wall Street is reassessing whether energy sector earnings growth can persist as Brent crude holds above $100 a barrel following renewed US-Iran hostilities on September 9.

Brent crude's push above $100 a barrel on September 9 is forcing Wall Street to reconsider whether energy earnings growth is temporary, potentially unlocking a valuation re-rating for a sector up 43 percent this year.
"The market is starting to price in that high oil prices may persist longer than initially expected," said Daan Struyven, co-head of global commodities research at Goldman Sachs, who sees "meaningful upside to crude oil prices" if shipping disruptions in the Middle East intensify.
Brent futures rose 2.2 percent to $100.07 a barrel in early European trading Wednesday, the highest since July 24, after the US military destroyed five Iranian oil tankers near Kharg Island and Iran retaliated with ballistic missiles toward Jordan. West Texas Intermediate climbed 1.8 percent to $94.73. Brent has gained roughly a quarter since early last month as hopes faded for a permanent resolution to the six-month-old US-Iran conflict.
The stakes extend beyond the energy complex. US 10-year Treasury yields jumped to their highest level since 2023 as investors priced renewed inflation risk from higher energy costs, while the S&P 500 fell 0.5 percent and the Nasdaq dropped 0.6 percent on September 9. Energy stocks rallied the same day, with Exxon Mobil and Chevron drawing support as the sector demonstrated defensive characteristics in a higher-oil-price environment.
Energy remains one of the S&P 500's cheapest sectors by valuation despite its 43 percent year-to-date gain, according to Bloomberg data. The State Street Energy Select Sector SPDR ETF has outperformed crude itself over recent months. Wall Street has largely treated the sector's earnings recovery as a temporary phenomenon tied to the Iran conflict, but analysts are beginning to reassess that view as operating margins are projected to hold near 15 percent through 2027, well above the roughly 9 percent pre-war baseline.
The question of duration is central. JPMorgan estimates every additional month of supply disruption adds $7 to $8 a barrel to Brent, with three months of disruption pushing average monthly prices to around $114. Goldman Sachs has flagged $120 as a potential ceiling if attacks on shipping intensify. Citi raised its third-quarter Brent forecast to $86 from $80, while ANZ lifted its short-term target to $95.
For energy companies, sustained prices above $100 translate directly into upstream profits and free cash flow. If high prices persist through year-end, analysts may be forced to raise forward earnings estimates for the sector, which would compress valuations that have not expanded despite the rally.
Higher energy costs feed into inflation expectations, which is why the 10-year Treasury yield has approached October 2023 highs. That dynamic pressures growth equities and supports the case for energy as a relative haven — a pattern visible on September 9 when the sector rose while the broader market fell. Average US diesel prices have already reached a record $5.94 per gallon, adding domestic political pressure ahead of November midterm elections.
US inflation data due Friday could cement expectations for a Federal Reserve rate hike next week, with the European Central Bank widely expected to lift rates Thursday. "The bump in oil prices naturally translates to a bump in concerns about inflation and a possible rate hike by the Fed," said Patrick O'Hare, chief market analyst at Briefing.com.
If Middle East tensions de-escalate and supply normalizes, oil prices would retreat and energy earnings expectations would follow. But with Strait of Hormuz shipping severely curtailed and global spare capacity shrinking, the market's buffer for absorbing supply shocks is thinner than at any point in recent years — a structural backdrop that suggests the $100 handle may hold longer than bears expect.
