The Savings and Investment Union

The Savings and Investment Union Could Be the Most Transformative Financial Policy in a Generation. Here's Why It Matters for Every European Citizen.

Right now, roughly €10 trillion in European household savings sits in low-yield bank deposits. That is not a typo. Ten. Trillion. Euros. Earning next to nothing while Europe faces an €800 billion annual investment gap that threatens its competitiveness, its green transition, and its security. The European Commission has finally acknowledged what builders and investors have been saying for years: this is unsustainable. The Savings and Investment Union, launched in March 2025, is the most ambitious attempt yet to change that equation. And if the EU gets this right, it will not just be a policy win. It will be a generational wealth unlock for 450 million citizens.

I have been writing about children's investment accounts, the intergenerational wealth transfer, and the need for better financial infrastructure for months now. This piece is about something bigger. It is about Europe finally building the financial architecture it has needed for decades, about the convergence of AI, blockchain, and capital markets policy, and why the SIU must go much further than what is currently on the table.

A Continent of Savers, Not Investors

The European Commission estimates that 70% of EU household savings are parked in bank deposits. EFAMA puts the raw figure even higher: household holdings of cash and deposits grew from €10.2 trillion in 2015 to nearly €14 trillion by 2022, while the ratio of capital market instruments to deposits actually fell. Surveys suggest only 18% of EU citizens have a high level of financial literacy. And an estimated €300 billion in European savings flows out of the EU and into non-EU markets every single year. That is European wealth funding American innovation instead of European companies.

Compare this to the United States, where participation in capital markets is deeply embedded in the culture and the infrastructure through 401(k)s, IRAs, 529 plans, and now Trump Accounts. About 58% of US households hold stocks or bonds. In much of Europe, the figure is a fraction of that. Europeans save into deposit accounts that, in many member states, do not even keep pace with inflation. This is not a cultural inevitability. It is a structural failure. And the SIU is designed to fix it.

What the SIU Proposes

The SIU was formally launched on 19 March 2025, born from the urgency of Mario Draghi's September 2024 competitiveness report (calling for €800 billion in additional annual investment) and Enrico Letta's single market report. It builds on the former Capital Markets Union, which made limited progress over a decade.

The strategy has four strands: getting citizens into capital markets through tax-incentivised Savings and Investment Accounts and financial literacy programmes; expanding financing for SMEs through securitisation reform and venture capital upgrades; consolidating market infrastructure by removing cross-border barriers; and pushing toward supervisory convergence across capital markets.

Actions are already underway. The Commission published its recommendation for EU-wide Savings and Investment Accounts and a Financial Literacy Strategy in September 2025. Measures to mobilise insurers' and banks' capital for equity landed in October. A major market integration package arrived in December, targeting the regulatory and supervisory barriers that keep EU capital markets fragmented. The securitisation framework is being overhauled to unlock lending to SMEs and infrastructure projects.

Yet progress remains uneven. The Draghi Observatory's first audit found only 11.2% of his 383 recommendations fully implemented after one year. Von der Leyen acknowledged the IMF analysis showing internal single market barriers equivalent to a 45% tariff on goods and a staggering 110% tariff on services. The ESM Managing Director recently framed the opportunity in starker terms, calling for Europe to mobilise its €40 trillion in total private savings to build strategic autonomy in defence, technology, and financial infrastructure.

The Transatlantic Mirror: Trump Accounts

While Europe debates timelines, the United States has moved with remarkable speed. Trump Accounts, created under the One Big Beautiful Bill Act, give every American child born between 2025 and 2028 a $1,000 investment from the U.S. Treasury, invested in low-cost index funds, locked until age 18. Families can contribute up to $5,000 per year. Within three days of the 2026 tax filing season, 500,000 families had signed up. Michael Dell pledged $6.25 billion to fund accounts for 25 million additional children. JPMorgan, BlackRock, Robinhood, and Charles Schwab announced matching contributions. There are already proposals to expand the investment rules to include digital asset indexes.

The concept is simple but powerful: give every child a stake in the economy from birth. Let compound growth do the work. Build financial literacy through ownership. The idea originally drew from Cory Booker's "baby bonds" proposal, but Trump Accounts diverge by investing in equity markets rather than government bonds, and by leveraging private sector participation at unprecedented scale. The fact that there are already legislative proposals to expand the investment rules to include digital asset indexes shows how fast this space is evolving.

Europe is not starting from zero. The UK ran the Child Trust Fund from 2002 to 2011, seeding over five million accounts before discontinuing prematurely. Germany has Junior-Depot accounts. Platforms like Scalable Capital and Curvo are building children's investment products. But there is no pan-European, government-backed equivalent. No programme that says to every European child: you have a stake in this continent's future.

The Case for European Children's Investment Accounts

The SIU factsheet already mentions "children's education" as a long-term savings goal. The financial literacy strategy targets young people. The SIA framework creates a new product category. All the building blocks are there. What is missing is the ambition to assemble them.

A pan-European Children's Investment Account, seeded by member states or the EU, invested in diversified European funds, portable across borders, and integrated with the SIU's financial literacy strategy, would be the single most powerful signal that this initiative is about people, not just market plumbing. It would give every European child a tangible connection to the continent's economy. It would create a generation of investors, not just savers. And it would directly address the €300 billion annual capital outflow by giving families a compelling reason to invest in Europe.

The numbers work. A modest €500 seed at birth, growing at 7% annually, reaches approximately €1,700 by age 18. Add €50 per month in family contributions and that figure rises to over €20,000. Scale across the roughly 3.7 million children born in the EU each year and you are looking at a significant new pool of long-term, patient capital flowing directly into European markets. This is not fantasy. This is compound interest plus political will.

The Future: Where AI, Digital Assets, and the SIU Converge

Here is where it gets really interesting. The SIU is being designed for today's financial system. But the system of tomorrow runs on entirely different rails, and Europe is building those rails in parallel.

Nine major European banks, including ING, UniCredit, and CaixaBank, have formed the Qivalis consortium to launch a MiCA-compliant euro stablecoin in H2 2026, backed 1:1 by deposits and short-term sovereign bonds, launching on Ethereum before expanding to Polygon and Base. S&P Global projects euro-backed stablecoin value could reach between up to €1.1 trillion by 2030, up from roughly €650 million today. Euro stablecoins currently represent just 0.2% of the total stablecoin market. That is about to change dramatically. Meanwhile, the ECB is advancing Project Appia, a tokenized financial ecosystem targeting full operationalisation by 2028 and aligning directly with SIU objectives. The digital euro, while delayed to 2029 at the earliest, is designed to coexist with private stablecoins and tokenized deposits in a hybrid system where public money anchors trust and private innovation provides speed and programmability.

Layer in tokenization. McKinsey projects the real-world asset tokenization market could reach $2 trillion by 2030. BlackRock, Franklin Templeton, and JPMorgan have already launched tokenized funds. Robinhood introduced tokenized stocks for European customers. The industry consensus in 2026 is that we have moved from "proof of concept" to production. For the SIU, this matters enormously. Tokenized European equities, bonds, and fund shares could become the native asset class of the next generation of Savings and Investment Accounts. Imagine a European Children's Investment Account where the portfolio is held in tokenized fund shares, settled in euro stablecoins, with contributions flowing from parents, grandparents, and employers via programmable smart contracts. Every component of that stack exists today.

Then there is AI. According to Wolters Kluwer, 44% of finance teams will use agentic AI in 2026, a 600% increase. KPMG estimates agentic AI will drive $3 trillion in corporate productivity gains globally. In the context of the SIU, AI is not a nice-to-have. It is the mechanism that makes mass retail participation actually work. The 82% of Europeans who currently lack high financial literacy are not going to navigate capital markets alone. They need AI-powered advisers that assess risk tolerance, recommend portfolios, automate contributions, and provide personalised education. I have been writing extensively about ERC-8004, the emerging standard for AI agent identity and trust on-chain. As agentic commerce scales and AI agents begin managing portfolios on behalf of retail investors, this trust layer becomes critical. Europe, with MiCA providing the most comprehensive digital asset regulatory framework in the world, is uniquely positioned to lead. But it requires policymakers to see the SIU as the financial foundation for an AI-native, tokenized European economy.

What This Means for Builders

For fintech founders and financial services innovators, the SIU is creating greenfield opportunities across traditional and emerging infrastructure. Every member state needs platforms to deliver Savings and Investment Accounts. The financial literacy strategy creates demand for AI-driven advisory and education tools. Securitisation reform opens doors for alternative lending. The 28th Regime (EU-Inc) would let startups build pan-European products from day one.

But the bigger opportunity sits at the intersection of policy and technology. A European Children's Investment Account built on tokenized rails, with AI advisory, euro stablecoin settlement, and cross-border portability via smart contracts, would be an entirely new product category. Think about the infrastructure required: custodial platforms supporting both traditional and tokenized assets, identity verification for minors, multi-party contribution systems with programmable payment flows, and AI-driven financial education that adapts to a child's age and learning level.

As someone building NestiFi, an AI-powered family investment platform, this is exactly the convergence I see taking shape. The platforms that win will not digitise existing savings accounts. They will build natively for a financial system where AI advises, blockchain settles, and every citizen has a stake from birth.

Europe's Moment

The SIU is the most important financial policy initiative the EU has launched since the euro. It addresses a real and quantifiable problem: too much European wealth sitting idle while the continent's investment needs grow more urgent by the quarter. But substance alone is not enough. Europe needs ambition. The United States is putting investment accounts in the hands of every newborn. Europe should do the same, and do it better.

More than that, Europe has an opportunity to leapfrog. While the US builds Trump Accounts on traditional custodial rails, Europe could build its equivalent on tokenized infrastructure from day one, with AI-native advisory, euro stablecoin settlement, and the regulatory clarity of MiCA already in place. The SIU does not have to be a catch-up exercise. It can be the foundation for the most advanced retail investment infrastructure in the world.

The €10 trillion is there. The policy framework is taking shape. The technology is ready. The building blocks of euro stablecoins, tokenized assets, agentic AI, and on-chain trust infrastructure are not theoretical. They are being deployed now, by European banks, European regulators, and European builders. The question is whether policymakers will connect these pieces into a coherent vision or let them develop in silos. For 450 million citizens, and for the generations that follow them, the answer matters enormously.
