Europe has no shortage of savings, but much of that money remains in bank deposits rather than flowing into businesses, innovation and long-term investment.

The European Commission’s Savings and Investments Union aims to change that by creating a more integrated financial system that connects household wealth with companies seeking capital.

The project is becoming a central part of the EU’s economic strategy as Europe faces rising investment needs in technology, energy, defence and industrial competitiveness.

Why Europe Wants More Investment

European households hold around €10 trillion in bank deposits. Deposits provide security and liquidity, but policymakers argue that citizens should also have easier access to diversified investment opportunities that could offer higher long-term returns.

At the same time, European companies need more capital to expand. Small and medium-sized businesses, start-ups and scale-ups remain particularly dependent on bank lending compared with companies in markets where equity financing is more developed.

Europe’s additional investment requirements are substantial. Estimates suggest the EU may need an extra €750–800 billion every year by 2030 to respond to challenges including technological change, the green transition and other pressing priorities.

A deeper capital market could help direct a larger share of existing European savings towards those needs.

Breaking Down National Barriers

One major obstacle is fragmentation.

Although the EU operates a single market, financial markets remain divided by national rules, supervision practices and different investment cultures. A company seeking capital across several member states can therefore encounter more complexity than its equivalent in a fully integrated domestic market.

The Savings and Investments Union is designed to reduce some of these barriers and allow financial services to operate more easily across borders.

The Commission has already introduced a market integration and supervision package aimed at improving the way European capital markets function. Greater consistency in supervision is also intended to make it easier for financial companies to expand across the EU rather than remaining concentrated in individual national markets.

Retail Investors Have A Role

Households are another important part of the strategy.

European policymakers want more people to participate in capital markets while ensuring that investment products remain understandable and appropriately regulated. Recent recommendations to member states have therefore focused on retail investment, financial literacy and supplementary pension schemes.

The idea is not simply to persuade households to move money out of savings accounts. The broader goal is to create conditions in which people who want to invest can access straightforward, diversified products and understand the risks involved.

Better financial knowledge is particularly important because investing always involves the possibility of losses as well as potential returns.

Banks Remain Central

Developing capital markets does not mean reducing the importance of banks.

Banks remain the main source of financing for much of the European economy and continue to play a central role in connecting households and businesses. The Savings and Investments Union therefore includes efforts to strengthen the EU banking sector and complete the banking union.

A more integrated banking market could allow institutions to operate at greater scale, improve competition and direct financing more efficiently across national borders.

The challenge is to increase competitiveness without weakening the safeguards introduced after previous financial crises. Any effort to simplify regulation must still preserve resilience, depositor confidence and financial stability.

Academics Join The Debate

The Commission is also drawing more heavily on academic research while developing the strategy.

In July 2026, Commissioner Maria Luís Albuquerque held a third dialogue with leading European academics to discuss financial regulation and the future of the Savings and Investments Union. Participants included economists Philippe Aghion, Agnès Bénassy-Quéré and Daniel Gros, alongside former Italian prime minister Mario Monti.

The discussions focused on market integration, supervision, banking competitiveness and ways to provide more financing for innovative companies.

Academic involvement matters because many of the reforms involve difficult trade-offs. Measures that make it easier for financial companies to grow across borders, for example, must be balanced against effective supervision and consumer protection.

What It Could Mean For Europeans

For ordinary households, the most visible changes could eventually include easier access to investment accounts, improved pension products and a wider choice of financial services across national borders.

For businesses, deeper European capital markets could mean more alternatives to traditional bank loans, particularly when financing expansion, research or new technology.

The Savings and Investments Union will not transform Europe’s financial system overnight. National regulations, investment habits and market structures remain deeply established.

But the direction is clear: Europe wants more of its existing wealth to finance its own economic growth. If integration succeeds, the result could be a financial system in which household savings have more opportunities to grow while European businesses gain better access to the capital needed to compete.
