Defense, Energy, Capital — Three Architectures, One Constraint That Will Define Whether Europe Reaches Its 2030 Targets
I want to start with a number that has been on my mind for several weeks now. Three hundred billion euros. That is how much European household savings flows into U.S. capital markets every year, according to the Letta report. Almost coincidentally, it is very close to the annual investment shortfall that the Draghi report identified for the European green and defense transitions. Once I started looking at the European sovereignty agenda through that single piece of arithmetic, the picture clarified — and I think it deserves an essay rather than a briefing.
A related number crystallized the argument. JPMorganChase, by itself, committed $1.5 trillion to its Security and Resiliency Initiative on 13 October 2025 — a fifty percent upgrade from its original $1 trillion commitment. One U.S. private financial institution, ten years, mobilizing more capital than the entire ReArm Europe envelope. I raise this not as a complaint about American power — it tells you something more specific about where the European capital architecture stands, and why the gap matters now rather than in the abstract.
Three Things to Hold On To
Three numbers anchor what follows.
→ Eight hundred billion euros. The total ReArm Europe / Readiness 2030 envelope that Ursula von der Leyen announced on 4 March 2025 — and what strikes me about this figure is how quickly the political system absorbed it. The 150 billion euro SAFE instrument, adopted by the Council on 27 May 2025, was oversubscribed almost immediately: initial requests hit 190 billion euros by February 2026, forcing the Commission to explore a successor facility. The remaining 650 billion comes from fiscal flexibility unlocked through the Stability and Growth Pact's national escape clause, which seventeen Member States had activated by February 2026. Then at the June 2025 NATO summit, alliance members committed to 5% of GDP on defense by 2035. A number that would have been unthinkable three years ago. The old 2% benchmark has become a floor.
→ One hundred and eighty-four billion euros. That is real money, already allocated under REPowerEU three years after its launch in May 2022. The results are hard to argue with: Russian gas imports collapsed from 45% of EU consumption in 2021 to 13% in 2025, and renewable capacity more than doubled. AccelerateEU, the Energy Union package that the Commission presented on 22 April 2026 in response to the Iran war, adds another layer — but I will come back to what it does and does not resolve.
→ Thirty-three trillion euros. The size of European household private savings, according to the Letta report. In theory, more than enough to finance every European sovereignty ambition for the next decade. Eighty percent sits in bank deposits. Three hundred billion of it leaves Europe each year to be deployed on Wall Street.
Read together, these three numbers define the European sovereignty arithmetic — and they explain why the next eighteen months will determine whether Europe finds a path through it, or chooses by default to lose two of the three.
A Note on What I Got Right and What I Did Not Anticipate
A few weeks ago, in Why It Matters: Hormuz/Capex, I argued that the Accelerated Regionalization scenario for global trade was running at roughly fifty percent probability. That reading has held — the 2026 Iran war, the Project Vault stockpile, the Critical Minerals Trilemma our team published earlier this month — they all confirm the regionalization trajectory rather than disrupt it. In The Dollarization Paradox essay published on 1 May, I argued that the architecture of dollar dominance is, paradoxically, the same architecture catalyzing its successors. That reading has held too.
Our team's CES briefing on The Rearmament Divide in late April established something more uncomfortable. It made the case that, for European boards, the era of incremental hedging — aligning with American defense industrial acceleration or building an autonomous alternative fast enough to matter — has expired. The third option, business as usual, is no longer available. I agreed with that briefing when we discussed it internally. What I did not adequately integrate at the time was the upstream constraint: the European capital arithmetic. I had treated European autonomy as a political question — willingness, ambition, strategic vision. I now think that frame is incomplete.
The European sovereignty agenda is, structurally, a capital arithmetic question. And capital arithmetic is unforgiving — which is why I am writing an essay rather than producing a briefing. The texture of the argument matters.
The Defense Track: ReArm Europe Has the Demand, Not the Mechanism
The political economy of European defense is now visible enough to read with some confidence, so I will start there.
The demand for European defense autonomy has hardened in 2025-2026 beyond anything the previous decade produced. SIPRI's 2025 Global Military Expenditure report, published in late April 2026, shows European defense spending rising by 14% to 864 billion dollars — the largest annual increase since the Cold War. Germany alone went up by 24% to 114 billion dollars, a level not seen since the Second World War. For the first time in the alliance's history, total NATO European spending will collectively surpass 2% of GDP in 2025. The constituency for higher defense budgets is no longer a niche position — it has moved into the mainstream of European politics.
The institutional mechanism has also begun to mature — and here, the pace surprised me. The European Investment Bank, which had historically restricted itself to dual-use projects, scrapped that limitation in 2025. It then quadrupled its security and defense lending to four billion euros, hitting its 2026 target a full year ahead of schedule. When EIB President Nadia Calviño held a press conference on 29 January 2026, the language had changed: she described a "step change" and spoke of a "robust pipeline" for 2026. That kind of language from the EIB on defense would have been unimaginable five years ago. Around the same time, the Defence Equity Facility — launched jointly by the EIF and the Commission in January 2026 — began mobilizing 175 million euros in private funds for defense innovation. The European Defence Fund stands at eight billion euros. SAFE was structurally oversubscribed.
So what is missing? In a phrase: scale.
The European Court of Auditors has already flagged that the European Defence Industry Programme lacks the budget to meet its objectives. The European Commission's own estimate is that an additional 500 billion euros are needed over the next decade just to close existing capability gaps in air and missile defense, electronic warfare, deep precision strike, and strategic enablers — a figure recently corroborated by the Kiel Institute's Sparta 2.0 paper, signed by Thomas Enders, Moritz Schularick, René Obermann and others on 7 May 2026. Now set that against the Commission's proposal for the 2028-2034 Multiannual Financial Framework: 115 billion euros in 2025 prices, or roughly 131 billion in current prices, for 'resilience, security, defense and space' combined. Better than the current 25 billion, certainly. But when the gap between what these estimates suggest is needed and what the MFF proposes is that wide, we are not talking about a budget shortfall. We are talking about a different order of magnitude. The NATO 5% GDP commitment by 2035, if executed, translates to roughly 650 billion euros in additional European fiscal space over four years. Real money — but calibrated for 2035, while intelligence assessments consistently point to 2030 as the latest horizon by which European industrial readiness needs to be operational.
This is what I mean by demand without mechanism. The political will exists. The institutional plumbing is being assembled. But the capital pipe remains too narrow. France, Italy, Belgium are already pushing against the reinstated Stability and Growth Pact ceilings — in practice, they are operating in genuine fiscal straitjackets. I have spent enough time around finance ministry corridors in the past six months to know that ideas are circulating intensely: a dedicated European Rearmament Bank, an intergovernmental defense vehicle modeled on the European Stability Mechanism, full Eurobond issuance for defense. Kaja Kallas formally proposed EU defense bonds in late 2025, and Macron publicly endorsed it. But none of these proposals has crossed the political threshold yet — and the German constitutional debate alone could take another eighteen months.
The defense track will, in my reading, deliver perhaps two-thirds of what was politically promised by 2030 — meaningful, but insufficient. And that gap between ambition and delivery is not something you can hedge away. It is a structural deficit dressed in political ambition.
The Energy Track: REPowerEU Has the Mechanism, Not the Speed
The energy leg reads differently, and I think more hopefully — at least on the surface. The mechanism here is considerably more mature than in defense. The funding architecture is more diversified. And the political consensus behind the energy transition has proven more durable than almost anyone would have predicted in the chaotic summer of 2022. What has not kept pace is the speed of execution, which remains too slow for the structural pressures now bearing down on it.
REPowerEU's three-year track record has been remarkable by any measure. Russian gas dropped from 45% of EU consumption to 13%. Russian oil from 27% to under 3%. Those are numbers I would not have believed possible in 2022. Solar capacity hit 320 gigawatts in 2025 — which was the original target, so credit where it is due — and the trajectory toward 600 gigawatts by 2030 looks credible. Renewable energy should cover 45% of EU consumption by 2030, up from the previous 40% target. And the Recovery and Resilience Facility has actually channeled 184 billion euros into REPowerEU-aligned projects so far. I emphasize "actually" because in European policy, the gap between announced funding and deployed funding is usually where ambition goes to die. Here, the money has moved.
But the headline numbers conceal a less flattering reality, and this is where the essay gets uncomfortable. Even after three years of acceleration, the EU still paid more than 21 billion euros to Russia for fossil fuels in 2024. I find that number hard to square with the political rhetoric. Then the Iran war began on 28 February 2026, and by April, the EU had spent an additional 24 billion euros on fossil fuel imports tied directly to the Middle East crisis. Fossil fuels still account for 57% of EU energy consumption — a number that rarely appears in the Commission's forward-looking communications. AccelerateEU, presented on 22 April 2026, is essentially Brussels acknowledging that the original REPowerEU timeline was insufficient. It rolls the Affordable Energy Action Plan of 26 February 2025 into a broader package with new measures on grid investment, common gas procurement, and accelerated permitting.
There is an awkward fact that AccelerateEU does not resolve, and I think it needs to be stated plainly. Replacing one dependency with another is portfolio diversification, not autonomy. Eighty percent of photovoltaic inverters used in Europe come from China. Critical minerals processing for the energy transition, as our CES team argued in The Critical Minerals Trilemma, remains dominated by Chinese refining capacity at roughly 70% across nineteen of twenty strategic minerals. What the energy transition is actually doing is swapping Russian gas dependency for Chinese mineral processing dependency. Progress on one dimension of sovereignty? Absolutely. But genuine strategic autonomy? Not yet.
The capital side is straining too. The European Investment Bank's broader lending to clean infrastructure, the ETS revenue redeployment, the InvestEU mechanism — all operational, but working at the margin. The Draghi report estimated that hitting climate neutrality plus the broader strategic autonomy agenda requires 750 to 800 billion euros of additional annual investment, or 4.5% of EU GDP. REPowerEU plus ReArm Europe plus the AI agenda combined are mobilizing perhaps 200 to 250 billion euros annually. That leaves a gap that is not 30% — it is structural.
My reading: the energy track delivers about 80% of what was promised by 2030. Better than defense, but still insufficient given that the demand curve is accelerating while the supply infrastructure decelerates. And that is the structural signature — every track produces real progress, and every track delivers it at insufficient scale.
The Capital Track: The SIU Has Neither Demand Nor Mechanism Yet
This is where the structural problem becomes most acute, and where the character of the analysis has to change.
The Capital Markets Union was launched in 2015, and for a decade it went essentially nowhere — a fact that the Commission itself implicitly conceded when it rebranded the project as the Savings and Investments Union on 19 March 2025. I thought the renaming was unusually honest for Brussels: it acknowledges that ten years of CMU effort failed to channel European savings into European investment. The new framing puts citizens — retail savers — at the heart of the project. Whether that reframing changes anything beyond the branding is the question that matters. As political signaling, I take it seriously. As capital architecture, it remains mostly aspirational.
The arithmetic speaks for itself. European households hold roughly 33 trillion euros in private financial wealth. Eighty percent of that sits in bank deposits. Pan-European pension products like PEPP have failed to gain traction because the 1% fee cap makes them economically unviable for most providers. Cross-border investment stays structurally low — fragmented insolvency regimes, fragmented supervisory frameworks, fragmented retail product markets all working against it. The aggregate result: 300 billion euros of European savings flow into U.S. capital markets every single year, while European companies — particularly small and medium-sized enterprises — cannot access patient growth capital at competitive cost.
Set this against the JPMorganChase number I opened with. A single U.S. financial institution, on a ten-year horizon, mobilizing 1.5 trillion dollars for industrial security and resiliency. That figure is entirely consistent with how U.S. capital markets work — they price strategic priorities quickly, at scale, with private institutions leading and government acting as catalyst. In Europe, the 1.5 trillion equivalent does not exist. Not because Europeans are poorer — they are not. The architecture to mobilize their wealth at that velocity has simply never been built.
The European Central Bank has documented the cost of this fragmentation: variability in lending margins across the eurozone remains higher than before the global financial crisis, even after a decade of supervisory convergence. European banks trade at a price-to-book ratio of roughly 0.79 times, against 1.53 times for U.S. banks over the period 2014-2021. Markets are not mistaken here — the discount reflects fragmented profitability, regulatory cost, and limited cross-border activity. The same dynamic shows up in equity returns: from 1900 to 2020, European equities returned an average annual nominal 7.2%, against 9.6% for the United States. Compound two and a half percentage points over a century and you understand why foreign investors own 40% of the U.S. stock market — and why European savings keep flowing westward.
Some progress has been made. In December 2025, EU finance ministers reached a Council position on revitalizing the securitization market — the first concrete legislative deliverable under the SIU. In June 2025, the Council agreed on harmonizing core elements of bankruptcy law, a foundational step toward unified insolvency standards. The Savings and Investment Account proposal of September 2025 echoes the Swedish Investeringssparkonto and the Italian and French preferential savings vehicles. The European Parliament passed a supportive resolution in September 2025. Commissioner Maria Luís Albuquerque has been visible at the Eurofi Forum.
But the political timeline of the SIU is, in my reading, incompatible with the political timeline of ReArm Europe and REPowerEU. The securitization regulation must still be agreed with the European Parliament. National insolvency regimes are notoriously sticky to harmonize. Pension reform requires Member State action that no one in Brussels can compel. The European Deposit Insurance Scheme, which would complete the Banking Union, has been blocked since 2015 by Northern Member States. Each of these elements is a multi-year project in its own right. Together, they constitute the SIU.
Without operational SIU progress by 2027, neither the defense track nor the energy track will hit their 2030 capital targets. The capital track is the upstream constraint of the entire sovereignty agenda — the one that determines whether the other two hold.
Three Scenarios for European Sovereignty Through 2030
With all three tracks in view, here is how I read the probability distribution over the next four to five years.
→ Scenario A — Differentiated Convergence (45%, base case). SIU progresses incrementally but unevenly. Securitization market becomes operational by 2027. Bankruptcy harmonization finalizes by 2028. SAFE delivers most of its 150 billion euros and a successor facility is launched in 2026-2027. EIB defense lending sustains at 4-5 billion euros annually and grows. REPowerEU hits 80% of its 2030 targets. AccelerateEU delivers an additional 20% on top. Total EU sovereignty investment reaches roughly 60-65% of the Draghi 750 billion euro annual target. Europe achieves real but uneven autonomy — strong in defense and energy, weaker in capital. The 300 billion euro annual savings hemorrhage to the U.S. shrinks to perhaps 200 billion. I consider this the most likely outcome — and I want to be precise about the language, because our CES team's Rearmament Divide briefing argued that incremental hedging has expired. I agree with that judgment. What I am describing here is not hedging. Hedging would be doing the same things and hoping for the best. Differentiated Convergence means choosing where to win — defense and energy first, capital second — and accepting the real cost of that prioritization. A strategic choice, deliberately made.
→ Scenario B — Forced Choice (35%). A major external shock — Trump tariffs on EU exports, escalation in Ukraine, a Taiwan-related crisis, a banking instability event — forces Brussels to make explicit prioritization choices on a compressed timeline. Defense and energy take precedence. The SIU stalls. The MFF 2028-2034 negotiations end unfavorably for the Competitiveness Fund. Capital fragmentation persists. Savings continue to flow to the U.S. at undiminished rates. Europe achieves narrower military and energy autonomy at the cost of lasting capital dependence. I suspect this is the scenario most boards are implicitly pricing in, even if they would not articulate it that way. The probability has increased meaningfully since I started thinking about this in March — the Iran war confirmed that external shocks are now the operating environment, not exceptions to it.
→ Scenario C — Structural Breakthrough (20%). A combination of political alignment — German fiscal rules reform, a successful Eurobond issuance for defense (the Kallas-Macron proposal moving from concept to implementation), a serious move on EDIS, robust SIU implementation — produces something approaching genuine European strategic autonomy by 2030. The capital arithmetic gets solved through deliberate policy. The 300 billion euro savings outflow is partially redirected into European productive investment. JPMorgan-scale capital pools begin to emerge in European markets. Most pro-European policymakers want this outcome, but it requires a level of coordinated political will that has been historically rare in EU history. I would not bet against it categorically — but I would not price it as the central case either.
What This Means, Concretely, For Boards and Asset Managers
For institutions deploying capital across European exposure, four disciplines now apply.
Discipline 1 — Treat the SIU as a strategic timeline, not a regulatory event. The progressive opening of European securitization markets, the harmonization of insolvency law, the rollout of Savings and Investment Accounts — none of these are one-off compliance items. They are sequential capital architecture changes that will reshape European financing costs, deal flow, and exit liquidity over the next three to five years. Institutions that map this timeline now will position themselves ahead of the consensus shift. Those that wait for the Council to adopt the next batch of legislation will find themselves reacting.
Discipline 2 — Distinguish defense exposure by jurisdiction and procurement architecture. European defense is not one trade — it is at least three. Pan-European platforms (Rafale, Eurofighter, FCAS or its successor, naval cooperation). National champions consolidating cross-border (Rheinmetall, Thales, BAE). And the dual-use innovation layer (cyber, space, drones, AI). Each has a different sensitivity to ReArm Europe funding flows, EIB lending, and EDIP procurement design. Generic "defense beta" misses the point entirely. The FCAS crisis our team analyzed in The Rearmament Divide is a useful reminder: parallel European programs can be politically attractive and industrially unviable at the same time.
Discipline 3 — Map the energy enabler layer, not just the energy generation layer. The clean energy transition is increasingly a transmission, storage, and behind-the-meter generation problem. Capital is flowing toward grid expansion, battery storage, electrolyzers, and industrial electrification — not just renewable generation. Critical minerals, as our team argued in The Critical Minerals Trilemma, sit at the foundation of all of this. The dispersion in returns will favor the enabler layer. AccelerateEU's emphasis on grid investment is the policy signal worth watching — more than the headline number.
Discipline 4 — Understand the FX and capital arithmetic of European sovereignty. As long as 300 billion euros of European savings flow to U.S. markets each year, European asset prices will reflect that capital scarcity. As the SIU progresses, that flow will partially reverse — and the implications for European equity valuations, sovereign spreads, and corporate funding costs are nowhere near priced in. Asset managers who model the SIU progression as a slow-moving capital flow story will be ahead of those who treat it as a regulatory sideshow. In my reading, this may be one of the most underappreciated sources of alpha in European markets through 2030.
A Note on Uncertainty
I should be honest about the limits of what I can see from here. German fiscal rules may or may not be reformed in the timeframe required to support a credible Eurobond defense instrument — I genuinely do not know. The Letta-Draghi-Noyer consensus on capital integration may or may not translate into Member State action; historically, that translation has been slow and often disappointing. Whether AccelerateEU produces structural change or marginal improvement remains an open question. And the Iran war ceasefire — how it resolves, what its second-order effects on European energy security will be over the next twelve to eighteen months — is beyond what any honest analyst can claim to forecast with confidence.
What I think I can say with some confidence is this: the European sovereignty arithmetic is real, it is structural, and it will be resolved between now and 2030. The resolution will be messier and slower than most boards are pricing in — and more dependent on capital architecture than on political ambition. But it will also be more genuine than the most pessimistic readings suggest. Differentiated Convergence is not a comfortable scenario. I believe it is an accurate one.
The institutions that map the capital arithmetic now — and act on it before the consensus shifts — will be substantially better positioned than those that wait. As I write this on 4 May 2026, the next eighteen months feel, more than ever, like the deciding window.
