Brent Holds Above $104 as Hormuz Disruption Revives Stagflation Debate
Sustained triple-digit crude from the Strait of Hormuz crisis has put central banks between an inflationary supply shock and recession risk.
ICE Brent crude front-month settled at $104.32 a barrel at Friday's (2026-09-12) close, and commentary on Bloomberg Surveillance on Thursday (2026-09-10) had already framed what that means for the Federal Reserve: pulling down the demand side of inflationary pressures would take "more than 25 basis points of hikes," one analyst said on the programme. NYMEX WTI front-month ended the week at $99.99 a barrel.5,4
The pressure has built since Brent first crossed $100 around Thursday (2026-09-03), as attacks on shipping in the Strait of Hormuz intensified and physical supply tightened. The old stagflation playbook resurfaced: higher energy costs drain household budgets and raise production costs while central banks face the uncomfortable choice between tightening against inflation and protecting growth.4
The breadth of the commodity rally since August reinforces the concern. European gas has risen 34% since the start of August, gasoline 22%, while metals including zinc and copper have moved higher alongside precious metals and agricultural soft commodities, Oilprice.com reported. Former Goldman Sachs commodities head Jeff Currie warned over the summer of 2026 of growing scarcity in the physical economy, a framing that gained traction as the Bloomberg Commodity Index climbed to multi-year highs.3
The Strait of Hormuz remains the pinch point. The Economist reported in May (2026-05-19) that oil flows through the strait were running roughly 95% below normal, a disruption that forecloses most re-routing options and keeps the physical market structurally short. Diplomatic signals from Washington pointing to a possible end to hostilities had not, as of that report, produced any material restoration of flow. Brent at $104 in September suggests little has changed.1
JPMorgan has mapped a straightforward price ladder. Every additional month of Hormuz-related disruption could add roughly $7 to $8 a barrel to Brent, the bank calculates. Under a three-month disruption scenario, JPMorgan puts average monthly Brent at approximately $114 a barrel, Times Now News reported.4
Tim Waterer, chief market analyst at KCM Trade, told Reuters the latest price moves reflected a combination of physical supply tightness and geopolitical factors, two forces that have compounded since the disruption began.4
Rystad Energy has put a number on the extreme scenario separately. A renewed US-Iran escalation could drive oil to $180 a barrel, the consultancy estimated. Brent at $104 is not pricing that outcome. But the gap between current levels and the tail has narrowed sharply since June.2
The case for stagflation is not automatically a case for recession. Real wages across advanced economies are growing by at least 1% a year, and global corporate earnings rose 15% in nominal terms in the fourth quarter of 2025 compared with a year earlier, the Economist reported. Higher energy costs impose a real income squeeze, but the macro starting point is stronger than in previous oil shocks.1
The 1990 Gulf War offers a cautionary parallel. WTI rose 166% over the course of that conflict, the Economist noted, and a recession followed. The downturn was shallow relative to earlier oil-shock episodes, partly because energy intensity in developed economies had already fallen from 1970s levels. The current price move is smaller, though the Hormuz disruption in relative flow terms is larger.1
What makes the policy arithmetic uncomfortable is where inflation stood before this started. Global price growth had pulled back to near 2% at the start of 2026, the Economist reported, after peaking above 10% in late 2022. An exogenous energy shock now risks reopening that work at the moment rate-cut expectations were most embedded in market pricing.1
ICE Endex TTF front-month European gas was at €79.51 per megawatt-hour at Friday's (2026-09-12) close, up 34% since August. That move adds a secondary transmission channel: the oil shock flows through to European power prices, industrial margins and household energy bills in a region that imports the vast majority of its energy.3
JPMorgan's per-month increment is the variable markets will track most closely. Three months of unrelieved Hormuz disruption points to roughly $114 Brent. Double that, absent a meaningful demand response, implies a materially higher floor. The strait remains effectively closed, and the path back to sub-$100 oil depends on whether it reopens.4
