A proposal backed by six of the European Union’s largest economies has placed capital markets reform back at the heart of the Brussels agenda, in what may prove to be one of the most consequential shifts in EU financial policymaking in recent years. Germany, France, Italy, Spain, Poland and the Netherlands have all supported stronger centralised supervision of European capital markets.
The fact that Germany is among the supporters is particularly noteworthy. Berlin has long been cautious about transferring supervisory authority from national regulators to EU-level institutions, so its support suggests that political resistance to deeper financial integration may be weakening.
The joint backing from these six countries gives renewed momentum to the EU’s Savings and Investments Union, an initiative intended to channel more household savings into productive investment across the bloc. The project is closely linked to the broader effort to build a more integrated European capital market.

For years, the EU has argued that its capital markets remain too shallow, too fragmented and too dependent on bank lending when compared with those of the United States. The European Commission states that EU capital markets are underdeveloped and fragmented, while earlier Commission material has also noted Europe’s reliance on bank financing.
Supporters of reform argue that more integrated capital markets would make it easier for businesses to raise funds, broaden investment opportunities for savers, and improve the EU’s ability to finance strategic priorities including climate policy, technological change and defence. The Commission’s Savings and Investments Union material presents this case explicitly.
Central to the current debate is the question of supervision. At present, oversight of EU capital markets remains largely national, even though financial activity is increasingly cross-border. Critics of the existing model argue that this produces uneven application of common rules and contributes to fragmentation.
A more centralised system would seek to reduce those differences, most likely by expanding the role of the European Securities and Markets Authority in areas involving major cross-border market activity. ESMA itself describes its mandate as promoting investor protection, orderly markets and financial stability, while current EU debate concerns whether that role should be enlarged.
Germany’s position matters because German governments have generally approached financial integration with caution, particularly where supervisory powers are concerned. Its support now suggests that economic pressures and the need for larger pools of investment capital may be shifting the balance of the debate in Brussels. The change is widely seen as breaking a longstanding deadlock.
The alignment of France, Italy, Spain, Poland and the Netherlands alongside Germany also gives the proposal broader political weight. It suggests that the issue is no longer simply an institutional ambition from Brussels, but a response to a widely recognised economic problem affecting the Union as a whole.
That does not mean agreement across the EU will be automatic. Resistance from smaller member states and national regulators remains possible, and negotiations on the shape and scope of centralised supervision are likely to continue well beyond this year. Reuters reports that ministers want governments to agree a joint position by mid-2026, with further talks involving the European Parliament extending into 2027.
The return of the Savings and Investments Union to the centre of the Brussels agenda reflects a broader recognition that Europe’s ambitions in competitiveness, industrial policy and strategic autonomy will require far greater mobilisation of private capital. Whether this push produces concrete institutional reform remains uncertain, but the political signal from the Union’s largest economies is unmistakable.
