From Covid to Hormuz: Europe’s Green Transition and the Return of Energy as a Macroeconomic Constraint

Official data. ECB Executive Board member Piero Cipollone estimated on 6 May that the net loss of oil supply was about 12 million barrels a day, roughly 11% of pre-war global supply, and warned that jet-fuel shortages could bring restrictions “akin to those seen during the COVID-19 pandemic”. The Covid-era financing link is also expiring: the Recovery and Resilience Facility, which funds part of green investment, is due to finish disbursing in 2026, leaving a public funding gap that ECB staff put at about €20 billion a year over 2025–30, roughly 24% of public needs.

The Energy Transition as a Macro Investment Cycle

Official data. ECB staff estimate additional green investment needs of 2.7–3.7% of 2023 EU GDP a year to 2030. The Commission puts the additional need at €477 billion a year (3.2% of GDP), within total green investment of about €1.2 trillion (8.3%), with generation and grids requiring nearly €150 billion a year; the IEA’s figure is lower, at €403 billion. The private sector would need to provide more than two-thirds. The programme spans generation, grids, storage, interconnectors, electrification of transport and heat, industrial process change, buildings and fuels such as hydrogen.

Official data on the long-term benefit. Renewables supplied 48% of EU electricity generation and nuclear 23% in 2024, so more than two-thirds was low carbon. EU energy intensity fell 32% over 2015–2025, energy consumption is 10% below 2021 and gas import volumes are 20% lower; the IMF estimates that efficiency gains and a cleaner mix cut the household cost of the current shock by 12% (ECB, 6 May, citing Eurostat and the IMF).

LBMR interpretation. Costs and benefits arrive in different orders. Upfront capital expenditure is certain and competes for labour, materials, equipment and savings; the energy-security dividend (lower import bills, lower volatility, lower marginal cost) is probabilistic and arrives later. Whether the transition is inflationary or disinflationary during the build therefore depends on supply-chain capacity, productivity gains and financing conditions, not on the destination.

Energy Shocks, Inflation and the ECB

Official data. September flash HICP was 3.8%, with energy at 18.8%, core at 2.5% and services at 3.2% (Eurostat, 2 October). Energy at about a 9% weight contributes roughly 1.7pp of the headline (LBMR calculation). The ECB deposit rate is 2.50%. ECB staff project headline inflation of 3.0% in 2026 and 2.5% in 2027, core rising to 2.6% in 2027, growth of 0.9% in 2026, real disposable income growth of 0.6%, and second-round effects of only 0.1–0.2pp. The negotiated-wage tracker points to 2.7% in the first half of 2027.

LBMR interpretation. First-round inflation is the mechanical pass-through of fuel, gas and electricity prices; it also cuts real incomes and growth. Persistence requires second-round channels: wages, services, margins and expectations. Five conditions make it more likely: energy prices that keep rising or recur, so that agents stop treating spikes as temporary; strong pricing power; a tight labour market; fiscal support that sustains demand; and supply bottlenecks. A shock that also weakens demand reduces firms’ pricing power, as Cipollone noted, which is why weak growth can limit persistence while still leaving the ECB with weaker income, weaker growth and higher inflation at once.

Market pricing. Markets price about a one-in-five chance of an October hike (Danske Bank, 2 October), and MUFG expects the next hike in December. National inflation shows the asymmetry of the shock: 5.0% in Spain, 4.1% in Italy and 3.4% in France in September (INE, ISTAT, INSEE).

Europe’s External Balance and Energy Security

Official data. The EU imported 57% of its energy in 2024, with oil 67% and gas 24% of energy imports. EU energy imports were €336.7 billion in 2025, down 11% on 2024 and 51% below the 2022 peak, although the value of LNG imports rose 35% (Eurostat). The euro-area current-account surplus narrowed to 1.7% of GDP in 2025 from 2.7%, and staff project 1.5% in 2026 and 2027. In its June projections ECB staff put the peak terms-of-trade loss in 2026 at about 0.4% of GDP, against 1.7% in 2022, before the September upward revision to energy prices. By 29 April the Commission President estimated an extra €27 billion spent on fossil-fuel imports since the war began.

LBMR interpretation. The channel runs from higher energy prices to a larger import bill, a weaker terms of trade, an income transfer abroad, weaker real incomes and a narrower surplus. Diversification away from Russia reduces supplier concentration; it does not insulate Europe from the global price. Qatar supplies only about 4% of EU gas imports, yet Hormuz removed about a fifth of global LNG supply (Bruegel; IEA). The US supplied about 58% of Europe’s LNG in 2025 (IEEFA) and Russia still supplies about 14% of EU gas (ACER). Europe is less exposed to Gulf energy than Asia and more than the United States, which is a net petroleum exporter (ECB). Shipping, terminals, interconnectors and critical minerals add further exposure.

Fiscal Space and the Rising Cost of Capital

Official data. Claims on public balance sheets are converging. EU defence spending reached €418 billion (2.2% of GDP) in 2025 and is projected at €454 billion (2.4%) in 2026 (EDA). NATO allies have committed to 5% of GDP by 2035, 3.5% of it core defence; the ESM estimates the 3.5% target adds about €45 billion a year for the euro area. Beside this sit green investment of 2.7–3.7% of GDP, energy-support measures of about 0.1% of GDP and a euro-area deficit that ECB staff see peaking at 3.7% of GDP in 2027. Cipollone warned that untargeted support could raise long-term yields and weigh on private investment.

Official data and external analysis on cost of capital. Clean power is capital-intensive. Financing can account for up to 50% of offshore-wind levelised costs and 20–50% of utility-scale solar, and levelised costs of clean projects rise faster than fossil projects as the cost of capital increases (IEA; OECD). The IEA estimates that a 2-percentage-point rise in the cost of capital raises the overall levelised cost of solar PV and wind by about 20% (World Energy Investment 2022). Euro-area bank rates in August were 3.77% on corporate loans and 3.60% on mortgages (ECB), before the September repricing in which the Bund yield reached 3.4–3.6%, the OAT 4.94–4.95% and the OAT–Bund spread about 133–142bp.

LBMR interpretation. This is the central paradox. A project with near-zero marginal operating cost can still be unfinanceable if the required return rises, so the faster Europe accelerates capital-intensive transformation, the more feasibility and timing depend on financial conditions. The loop is damaging if left unmanaged: higher rates delay investment, delay prolongs exposure to imported energy, and exposure raises inflation risk and rates. Fiscal credibility is a cost-of-capital input too: the spread between French and German yields is the price of that credibility, and it falls on the countries with the least fiscal room. That is the case for jointly financing cross-border grids, which the ECB and the Draghi report support.

Industrial Competitiveness and Geopolitical Fragmentation

Market pricing and official data. Dutch TTF gas was about €73.5/MWh on 5 October, roughly $24/MMBtu at EUR/USD 1.13, against about $3.03 for US Henry Hub: a gap of about eight times (LBMR conversion). The Draghi report put the 2024 gap at four to five times. The US is not immune: Henry Hub hit a record $30.72 in January 2026 during a cold snap (IEA). On inputs, China is the top refiner for 19 of 20 strategic minerals, and for gallium, graphite, manganese and rare earths it supplies more than 90% (IEA).

LBMR interpretation. The transition changes the composition of geopolitical exposure rather than removing it: from hydrocarbon chokepoints to LNG terminals, shipping lanes, interconnectors, minerals, batteries and semiconductors. Sector effects diverge. Electrification equipment, grids, storage and contracted low-carbon generation can benefit from structural investment if financing holds. Energy-intensive chemicals, fertilisers, aluminium, steel and glass, where gas sets the marginal price and switching costs are high, remain vulnerable, as the Hormuz disruption to fertiliser, aluminium and helium supply illustrates (ECB).

Financial-Market Transmission

Exposures differ widely because assets respond to different combinations of energy prices, real rates, fiscal policy, regulation, growth and geopolitical risk. The table shows macro transmission, not security selection.

Three European Macro Regimes

• Transitory shock. Energy prices normalise and second-round effects stay limited, close to the ECB baseline (2027 headline inflation 2.5%). The ECB holds at 2.50%; term premia retrace, financing conditions ease and transition investment resumes.
• Persistent supply shock. Energy costs stay elevated, like the ECB’s adverse scenario (2027 headline 3.2%, core 2.8%). Growth stays weak while inflation proves sticky; the ECB tightens at most modestly, accepting the output cost, and cost of capital rises through the term premium.
• Regime shock. Scarcity, fiscal expansion, wage adjustment and fragmentation reinforce one another, as in the severe scenario (2027 headline 5.4%, core 3.5%).

LBMR interpretation. The third regime is particularly difficult. The instrument that restores price stability, higher rates, raises the financing cost of the investment that would reduce future vulnerability, widens sovereign spreads in the countries least able to bear them, and cannot create energy supply. Expansionary fiscal policy for defence and energy relief pushes in the opposite direction. Easing risks de-anchoring expectations, while tightening risks a financial-stability problem; the Transmission Protection Instrument addresses disorderly spreads, not the underlying supply shortage. Monetary policy would be asked to do the work of energy and industrial policy.

Strategic Implications for Investors

The key portfolio insight is that the transition creates very different exposures depending on six factors: energy prices, real rates, fiscal policy, regulation, growth and geopolitical risk. A portfolio of regulated utilities, infrastructure, long-duration green assets and European sovereign bonds can look diversified while expressing one view on the cost of capital. The sensible discipline is to test exposures against each factor separately, and to ask which assets benefit from lower energy-import dependence and which depend on cheap financing. These are analytical considerations, not security recommendations.

Conclusion: From the Price of Energy to the Price of Capital

Covid demonstrated the power of governments to respond to an extraordinary shock. The Green Deal is a deliberate transformation of Europe’s productive and energy system. Hormuz shows that physical and geopolitical energy constraints can still generate major macroeconomic shocks during that transformation. Europe’s objective should therefore be decarbonisation combined with energy abundance, resilience, competitive energy costs and lower geopolitical dependence.

For investors the crucial variable may ultimately be neither the price of oil nor the price of carbon. It may be the price of capital required to build Europe’s next energy system. Its productivity and financing, not the replacement of one energy source with another, will determine whether Europe reconciles decarbonisation, security, competitiveness, fiscal sustainability and monetary stability.
