Hormuz Closure Adds Financing Drag to Europe's Offshore Wind Recovery
Prolonged Strait of Hormuz disruption and a summer of European heatwaves are adding financing pressure to offshore wind projects fighting to recover momentum.
A series of extreme heatwaves has pushed European power systems toward a stress level that analysts told Montel on Thursday (2026-08-27) could prove comparable in severity to the Hormuz supply shock itself, with French and Spanish power exports bearing an outsized share of balancing a strained continental grid. Climate change, the analysts said, is making what was once exceptional recurrent.7
Two days earlier, a market analyst had warned Montel on Tuesday (2026-08-25) that the Strait of Hormuz closure was casting a "dark cloud" over the recovery of offshore wind deployment in Europe. The mechanism is not direct supply disruption but macroeconomic pressure: higher inflation and rising interest rates, both amplified by the energy price shock from the closed chokepoint, are eroding the financing conditions that offshore wind projects depend on.6
Europe's offshore wind buildout is acutely sensitive to rate cycles. Developers finance turbine installations over decades, and even modest increases in the cost of debt compress project economics when contracted power prices were set before the current inflation wave. The squeeze lands at the moment the sector was beginning to rebuild confidence after years of supply chain disruption and permitting backlogs.6
J.P. Morgan data shows the physical scale driving those cost pressures. In a report sent to Rigzone late Tuesday (2026-07-21), J.P. Morgan analysts said confirmed crude shipments through the Strait of Hormuz had fallen from 12.5 million barrels per day to 5.1 million barrels per day, with Persian Gulf product exports also declining. Open interest in global energy markets jumped 10% week-on-week, a rise of $72 billion, to $821 billion. Natural gas open interest alone climbed 10% to $197 billion, driven, J.P. Morgan said, by rising prices across European and Asian benchmarks.5
ICE Endex TTF front-month stood at €66.79 per megawatt-hour at August 29's close. German baseload power settled at €137.88 per megawatt-hour on August 29, reflecting months of accumulated pressure from restricted Persian Gulf flows.5,7
The investor picture is more complicated. A UKSIF survey of firms managing around $7.4 trillion in assets found 87% of respondents expected global renewable energy investment to increase, and 78% said they viewed renewables as less risky relative to oil and gas since the war began. But institutional sentiment is not the same as project-level capital: that requires financing conditions which are moving in the wrong direction for developers trying to close deals now.3
Analysts were raising the alarm as far back as May. Market participants told Montel on Monday (2026-05-18) that Europe was underestimating the risk of a sustained Hormuz closure, with rising Asian LNG demand competing directly against EU seasonal stock replenishment and the potential for a sharp repricing in European gas. At Montel's German Energy Day on Thursday (2026-05-21), a commodities investment manager said the current price shock would tip into a supply crisis if the strait stayed shut for another year.2,1
Some relief had come through demand destruction in Asian countries, easing pressure on global LNG markets through mid-year, Seb Kennedy, independent energy analyst at Energy Flux, told Montel. That buffer depended on Asian economic conditions holding, not on any resolution of the chokepoint itself.2
A tentative reopening emerged in late June. Oilprice.com reported on June 23 (2026-06-23) that tankers were broadcasting their positions and signalling intent to transit the strait, suggesting some recovery of traffic through the chokepoint. ICE Brent crude front-month stood at $88.10 per barrel in August 30 price data. JKM Asian LNG settled at $23.17 per MMBtu on August 29, reflecting the premium Asian buyers have accepted to secure seaborne supply while competing with European importers for the same cargoes.4
For offshore wind developers, the timing pressure is acute. Auction cycles impose deadlines that cannot wait for macroeconomic conditions to ease. With European heatwaves continuing into late August sustaining gas consumption, TTF is staying elevated — and the financing environment analysts flagged as damaging to wind project economics shows no sign of improving. How fast Hormuz traffic normalises, and whether that pulls European gas prices down before the next major offshore wind auction round, is the specific variable developers and their financiers will be tracking through the autumn.6,7,4
