Morgan Stanley lowered its stance on European energy stocks to "equal-weight" from "overweight," pointing to the partial reopening of the Strait of Hormuz under a U.S.-Iran memorandum of understanding and what it describes as a structural weakening in the sector's earnings outlook.
The decision pushed energy down in the broker's European sector ranking, moving it from fourth to ninth place in Morgan Stanley's sector model. A key modelling input - the sensitivity to a Strait of Hormuz reopening - was doubled; that input had represented an 8% weight in the model before the agreement was announced.
The broker said the change reflects the deal's effect on oil prices and on energy equities' relative performance. In support of the call, Morgan Stanley's historical review of past geopolitical escalation periods - including the 1973 Oil Embargo, the Iranian Revolution, the Gulf War, the Iraq War, and the Russia-Ukraine conflict - found that energy stocks tend to underperform after geopolitics-driven oil prices peak, and it said the current cycle is following that pattern. MSCI Europe energy sector relative performance, Morgan Stanley noted, has already turned lower following the oil price peak.
Consensus models for European energy had been assuming an average Brent price of $88.50 per barrel in 2026, which implies roughly $83 per barrel for the remainder of this year. At the time Morgan Stanley wrote, dated Brent was around $77 per barrel. The broker's oil strategists see Brent "fundamentally anchored to c. $80/bbl from 4Q through 2027," a view Morgan Stanley said underpins the equal-weight recommendation.
Early market data reinforced the cautious stance. Four-week earnings revisions breadth for the energy sector had already turned negative relative to the broader European index, which the analysts said signals downside risk to the wider three-month revisions measure.
Morgan Stanley also flagged a recent uplift in MSCI Europe 2026 earnings per share growth - from 11.2% to 16.7% - and said that increase has been "largely driven by the Energy sector," creating a high base and skewing revision risk to the downside. Morgan Stanley's own forecast for European earnings growth for 2026 remains 11.2%.
As part of the model update, six energy names were removed from the broker's top 50 combined stock screen, which feeds the sector ranking. Those energy stocks were replaced by three banks, two utilities, and one copper stock. The energy companies dropped from the screen included TotalEnergies SE, Aker BP ASA, Repsol SA, OMV AG, Tenaris S.A., and Neste Corporation.
Implications for markets and sectors
- European energy equities face a more constrained upside scenario as a result of the Hormuz memorandum and the broker's reassessment of oil-price risk.
- Within Morgan Stanley's modelling framework, the change alters sector rankings and the composition of the broker's top stock selection, with energy giving way to financials, utilities, and a materials name in the top-50 screen.
- Short-term earnings revision metrics and a high 2026 EPS growth base concentrated in energy raise downside revision risk for the sector relative to the broader market.
Bottom line
Morgan Stanley's downgrade reflects both a geopolitical development - the partial reopening of the Strait of Hormuz under a U.S.-Iran memorandum - and a reassessment of oil-price dynamics and earnings sensitivity embedded in its European sector model. The broker's oil strategists' view that Brent will be anchored around $80 per barrel through late 2027 supports the equal-weight call, while early earnings revision data and a concentrated lift to 2026 EPS expectations from energy create revision risk going forward.
