The recent episode involving a significant stake acquisition attempt by Italian bank UniCredit in its German counterpart, Commerzbank, in 2024, illuminated a persistent tension within the European Union’s financial architecture. The German government’s staunch opposition, labeling the move "hostile" and emphasizing Commerzbank’s critical role for German industry, was met with a warning from European Central Bank (ECB) officials that such nationalistic resistance undermined the very fabric of the single European banking market. While Commerzbank ultimately rejected the overture, the situation served as a potent reminder of a fundamental paradox: despite a widespread endorsement of deeper financial integration, individual member states often exhibit a profound reluctance to relinquish control. This internal friction, however, is increasingly being overshadowed by growing calls for enhanced EU financial autonomy, a sentiment amplified by a complex interplay of geopolitical shifts and evolving global economic dynamics.
The quest for a truly sovereign European financial sector has been a long-standing aspiration, dating back to the inception of the EU single market in the 1990s. Proponents have consistently argued that the bloc cannot achieve genuine superpower status without a financial services industry that is not only pan-European in scope but also globally competitive. However, recent events have injected a palpable urgency into these demands. The departure of the United Kingdom from the European Union (Brexit) represented a significant blow, depriving the bloc of the City of London, its sole globally prominent financial hub. Since then, the EU has been left with a fragmented landscape of financial centers, including Frankfurt, Dublin, Paris, Milan, and Amsterdam, none of which possess the scale or influence of New York or Hong Kong. Compounding this challenge was Russia’s invasion of Ukraine, which triggered unprecedented financial sanctions, including the exclusion of Russian banks from the SWIFT messaging system and the freezing of Russian assets within Europe. These actions starkly underscored the EU’s deep-seated reliance on the US financial infrastructure.
The election of Donald Trump to the US presidency in 2024 served as an even more profound wake-up call. His administration’s economic policies, characterized by a pronounced nationalist bent and a more protectionist stance towards European products, amplified the imperative for European strategic autonomy. Remarks made by Vice President JD Vance in Munich, coupled with renewed US pressure on Denmark regarding Greenland, hinting at potential US control, unsettled European policymakers and signaled a potential recalibration of the long-standing transatlantic alliance. The apprehension that the once-unshakeable bonds of this alliance might be fraying has now permeated the financial sector, leading to open questioning among European leaders about the future reliability of the Federal Reserve as a global lender of last resort, a role it so critically fulfilled during the 2008 Great Recession, particularly under a potentially more inward-looking US administration.
In this evolving landscape, a significant report spearheaded by former ECB President Mario Draghi has injected fresh impetus into the discourse on European financial sovereignty. Draghi’s analysis posits that the EU risks falling behind its global competitors if it fails to accelerate its financial integration, framing the challenge as a strategic imperative in an era of increasing geopolitical fragmentation. This perspective is further reinforced by a separate EU-commissioned report led by Enrico Letta, which emphasizes the need to complete the internal market to unlock greater scale. Letta’s proposals advocate for the dismantling of barriers to cross-border investment, the harmonization of regulatory frameworks, and the strengthening of common institutions to effectively mobilize private capital. Both reports highlight persistent structural weaknesses within the EU’s financial system, including fragmented capital markets, limited risk-sharing mechanisms, and an insufficient depth in financial services. They issue a stark warning: without substantial reform, Europe will struggle to finance its ambitious priorities, ranging from the green transition and digital innovation to, critically in the current geopolitical climate, enhanced defense capabilities. While European policymakers have acknowledged the gravity of these findings, concrete action has been notably slow. Holger Schmieding, chief economist at Berenberg Bank, notes that while the Draghi report has been widely discussed and has shaped the debate, "so far, few of the steps Draghi has recommended have been taken." Nevertheless, the collective impact of these reports has been to crystallize a growing consensus that financial integration is indispensable for Europe to secure its strategic autonomy.
At the core of this intensifying debate lies the consolidation of EU capital markets, a project that has been on the EU’s agenda for over a decade. The Draghi report identifies the underutilization of the bloc’s accumulated capital as a significant weakness in Europe’s economic model. When compared to the United States, Europe has historically struggled to effectively channel household savings into productive investments for companies, particularly in the high-growth technology sector. It is estimated that approximately €14 trillion of retail capital in Europe remains largely dormant in traditional bank deposits. Adding to this concern is the observation that the US financial sector is increasingly dominating Europe’s investment landscape. American investment banks already command a substantial share of the European capital markets, accounting for roughly 40 percent of investment banking fees and an even larger proportion in crucial areas such as mergers and acquisitions (M&A) and equity underwriting. The dominance of three major US asset managers – BlackRock, Vanguard, and State Street – continues to expand their presence across Europe, often while maintaining a home bias towards US investments. This underdevelopment of the European sector is partly attributed to national governments’ historical tendency to discourage cross-border activity, aiming to preserve domestic savings and sustain demand for their own public debt.
In an effort to invigorate Europe’s capital markets, the European Commission has revived its long-standing Capital Markets Union initiative, now framed under the broader umbrella of a "Savings and Investment Union." The proposed measures under consideration include a range of incentives designed to encourage retail investment in European assets, adjustments to capital requirements for banks and insurers to foster lending, and reforms to private pension and savings frameworks aimed at directing household savings towards capital markets. A parallel objective is to establish a unified regulatory regime for equities, bonds, and other investment vehicles, which is expected to bolster investor confidence and diminish opportunities for regulatory arbitrage. By harmonizing regulations and removing impediments to cross-border investments, the initiative seeks to diversify funding sources for businesses, moving beyond their traditional reliance on the banking sector.
These reforms are also intended to indirectly address a persistent challenge in the European economy: the phenomenon of "overbanking." This refers to the existence of an excessive number of banks competing for a relatively fixed pool of capital. The sheer volume of banks across Europe has historically limited economies of scale, weakened competition, and consequently encouraged businesses to lean more heavily on bank lending rather than exploring bond or equity financing. This dynamic, in turn, has hampered the development of deeper and more sophisticated capital markets. Skeptics, however, caution that even if fully implemented, these proposals may not sufficiently address the deep-seated structural issues. Carsten Brzeski, global head of macro research at ING Research, expresses concern that "the proposals so far will further harmonise capital markets but not complete it the union." He further notes that "another hampering issue will be tax issues and how to deal with different taxation of capital gains and asset wealth."
Despite these reservations, a gradual shift in the political climate is fueling a degree of optimism. The EU’s largest economies have publicly backed the Commission’s proposal to expand the supervisory role of the European Securities and Markets Authority (ESMA) in Paris. This would grant ESMA direct oversight of key cross-border market infrastructures, including central counterparties, securities depositories, selected trading venues, and crypto-asset service providers. Currently, regulatory oversight remains largely decentralized at the national level, even for institutions whose operations span multiple jurisdictions, reflecting a persistent resistance from member states to ceding authority to EU-level bodies. Economist Ignazio Angeloni, a senior policy fellow at the Leibniz Institute for Financial Research SAFE and former member of the ECB’s supervisory board, acknowledges that "national regulators have and will continue to have for a long time a key role as components of the euro area-wide supervisory system." He advocates for a hybrid model, similar to the one established for banking supervision under the ECB during the eurozone debt crisis, as the most viable approach. Angeloni suggests that "The structure of the Single Supervisory Mechanism (SSM), where the supervisory board, effectively its decision-making arm, includes national banking supervisors as voting members, has proved viable and can be extended to market supervision."
The long-awaited Banking Union project is inching closer to fruition, a crucial step in reforming Europe’s financial architecture. However, dismantling the national barriers that fragment European banking has proven to be a protracted and politically sensitive endeavor. Initially launched with considerable fanfare in 2012 during the Eurozone debt crisis, the project remains incomplete. Banking within the eurozone continues to function as a collection of loosely connected national markets, with deposit and loan markets largely remaining under national control. The crisis itself triggered a significant retrenchment in cross-border banking activity, leading to a notable decline in EU banks’ cross-border exposures and interbank lending. Nonetheless, Angeloni argues that the Banking Union has successfully achieved its initial objective: enhancing bank safety and preserving financial stability. He points out that "No significant banking crises have occurred since then, while there have been some elsewhere in the world, bank balance sheets have been cleaned and bank profitability restored."
The missing element in this equation, according to most analysts, is a shared deposit insurance scheme that would serve as a common safety net for depositors across the bloc. Without such a mechanism, national governments remain intrinsically linked to their domestic banking systems. The European Commission harbors hopes that reviving plans for a European Deposit Insurance Scheme (EDIS) could unlock deeper integration by fostering the growth of cross-border banking groups and simplifying the process for lenders to operate across national borders. Brzeski considers the EDIS plan to be "critical" in an ideal scenario, but acknowledges that "In a more realistic world, a second-best capital markets union would not necessarily require a full EDIS but simply enough trust in the stability and solidity of harmonised national schemes." The fundamental political obstacles that have historically stalled the project have not abated. Countries such as Germany and the Netherlands have consistently voiced concerns regarding risk-sharing, wary of assuming liabilities for banking systems in countries with historically higher rates of non-performing loans. Conversely, southern member states argue that without shared protections, true integration will remain elusive.
Encouraging cross-border mergers and acquisitions is another pivotal objective. Brussels contends that greater consolidation within the banking sector could enhance profitability, particularly in an environment marked by digital disruption and intensifying margin pressures. The Draghi report takes this argument a step further, proposing that cross-border banking activity should be treated as equivalent to national activity through a "country-blind" supervisory regime. However, smaller nations harbor fears that consolidation could lead to the demise of their domestic banking sectors, leaving their financial systems vulnerable to domination by larger economies. Many national governments continue to offer direct or indirect guarantees to their domestic banks, seeking to preserve a "national champion" capable of competing on an international stage. Regional banks also continue to play a significant role in several countries, benefiting from less stringent supervision by national regulators compared to the oversight applied to larger banks by the ECB. Nevertheless, Angeloni emphasizes the critical need to foster a few dominant players capable of competing with their US and Asian counterparts if the EU is to achieve genuine financial sovereignty. He observes that "At present, even the largest EU banks have a largely national footprint. Because of lack of scale, they cannot compete with non-EU banking giants even in EU markets, particularly in investment banking and related areas, such as M&A and IPOs."
On the monetary front, a cornerstone of the ECB’s strategy is the development of a digital euro, a central bank digital currency (CBDC). A pilot phase is anticipated to commence next year, with full issuance projected before the end of the decade. While still contingent on political approval, the digital euro project has emerged as a critical pillar of Europe’s ambition to reduce its external dependencies, particularly in light of an increasingly assertive US and the dominance of the US dollar. Matteo Bursi, a researcher specializing in the digital economy at the Italian think tank Istituto Affari Internazionali, suggests that "The aggressive stance adopted by the US over the past year toward the EU has certainly contributed to unblocking the legislative process related to the digital euro."
At its essence, the digital euro aims to provide European citizens and businesses with a state-backed electronic means of payment, complementing physical cash. For policymakers, it addresses a strategic concern: Europe’s profound reliance on foreign payment providers, including US card networks and rapidly expanding private platforms. The introduction of a digital currency would offer Europeans access to a secure, public payment option in an era characterized by the proliferation of private stablecoins and big tech payment systems. Rebecca Christie, a capital markets expert at the Brussels-based think tank Bruegel, notes that such a development would also preserve the role of central bank money in the digital age. She emphasizes, "It is important that the ECB be the reference point for all things euro, not some kind of privately developed product that becomes the default because it found an unoccupied niche in the markets."
Nevertheless, the initiative faces considerable scrutiny. European banks have voiced concerns about potential deposit outflows, while privacy advocates question the safeguards for user data. The ECB has attempted to address these anxieties by proposing holding limits and stressing the confidentiality of transactions. Bursi, however, contends that "The significant limitations currently being imposed on the digital euro, such as the absence of interest on deposits and the introduction of holding limits, substantially weaken the instrument, preventing it from serving monetary policy purposes and constraining its potential as an alternative to private bank deposits." He further posits that uptake could remain low, a scenario that would validate the arguments of project opponents who dismiss it as a wasteful expenditure of public resources. Ultimately, the digital euro represents a project that is as much political as it is technological and financial. Bursi cautions, however, that expectations of a substantial impact on the euro’s international role should be tempered, stating, "It would be misleading to expect a substantial impact, given that the use of the euro as a global reserve currency remains constrained by limited financial integration among European countries, in particular by the absence of a safe asset comparable to US Treasurys."
This fundamental lack of a readily available, deep, and liquid European safe asset is a key reason why calls for a more robust EU-issued bond market are gaining traction in Brussels. Proponents argue that a larger pool of jointly issued debt, functioning as a European safe asset, could attract significant long-term global capital and ultimately lower borrowing costs across the bloc. In stark contrast to the vast $40 trillion US Treasury market, Europe’s sovereign debt landscape remains highly fragmented, with national bond markets dominating. This fragmentation limits scale and diminishes the euro’s appeal as a global reserve currency.
Momentum for such an initiative has been building since the pandemic-era launch of joint borrowing through a recovery fund. This initiative demonstrated both investor appetite for common European debt and the bloc’s capacity to issue large volumes of such instruments. Supporters now see an opportunity to transform this temporary measure into a more permanent feature of the EU’s financial architecture. However, political resistance has historically been a significant impediment. Frugal northern countries, deeply rooted in fiscal prudence, have expressed reservations about mutualized debt, fearing it could inadvertently lead to subsidizing more indebted member states. Schmieding of Berenberg Bank argues that "Jointly issued debt would enhance the international role of the euro and strengthen the financial sovereignty of the EU. But in the multi-national EU, joint bonds must be subject to strict conditions. They should only be issued to finance genuinely new common tasks, for instance as help for Ukraine or for common defence projects." He cautions, "They should not finance pre-existing EU tasks or national budgets. Otherwise, they would dilute the fiscal discipline that is required to keep borrowing costs low enough to be sustainable."
Another significant hurdle is the EU’s perceived lack of fiscal capacity to adequately support substantial debt issuance. Nicolas Véron, a senior fellow at the Peterson Institute for International Economics and an expert on financial reform, emphasizes that "You need to embed Eurobonds in a political framework, which is essentially a fiscal union where you also have tax revenue at the European level to back those bonds." He further notes that "That requires treaty change, which is very difficult under the current circumstances." Nevertheless, mounting geopolitical tensions, the imperative for large-scale investments in defense and energy, and a growing recognition of Europe’s financing gaps are beginning to reshape this debate. Moreover, fiscal conditions in southern Europe have demonstrably improved, with countries like Spain, Italy, Portugal, and Greece witnessing stable or falling debt levels alongside credit rating upgrades. These positive trends are gradually softening opposition and creating an opening for incremental steps toward greater common debt issuance.
Europe’s ambition for financial sovereignty is also confronted by a critical vulnerability: the significant reliance of its financial system’s backbone on non-European providers. European banks are deeply dependent on US cloud companies such as Amazon Web Services, Microsoft Azure, and Google Cloud for data storage and critical operations, a dependency that introduces concentration risk and exposes the sector to potential geopolitical or regulatory disruptions. Furthermore, Europe’s fintech sector has struggled to replicate the dynamism observed in its US counterparts. Investment levels remain comparatively lower, and the market is fragmented along national lines, hindering the ability of European fintechs to scale into global players. Many promising European fintech ventures are reportedly considering the US as a listing destination in search of deeper investor pools. Revolut, often cited as Europe’s largest fintech, has indicated a likelihood of choosing the US for its initial public offering. Payments represent another crucial battleground. A substantial portion of Europe’s card-based payment system is routed through US giants like Visa and Mastercard, while Chinese players such as Alipay and WeChat Pay are also making inroads into the European market. In response, EU policymakers and industry groups are actively exploring initiatives to develop alternative payment solutions. However, effectively addressing these challenges will necessitate sustained investment, enhanced regulatory coordination, and a robust political will. Bursi suggests that "The digital euro, if designed appropriately, would lead to the creation of a payment system that is independent from those currently in use, primarily US-based, and could therefore help reduce Europe’s reliance on foreign providers." Yet, without a more formidable domestic fintech ecosystem, Europe risks remaining beholden to foreign technology, thereby undermining its objective of achieving financial sovereignty in the digital age. Bursi warns that "The likelihood that the US could exploit Europe’s dependence on payment systems has remained limited, yet with Donald Trump’s return to the White House, those risks have increased." He concludes that "Although some initiatives have begun to take shape in Europe, the EU still lacks major private solutions capable of ensuring strategic autonomy in areas such as proximity payments."
Optimists within the EU institutions harbor the hope that these various initiatives, despite their disparate scopes, will ultimately reinforce one another, fostering a virtuous cycle that could revitalize Europe’s financial sector. A strengthened Banking Union, for instance, would provide crucial support for the Savings and Investment Union by cultivating more stable cross-border banks capable of channeling savings into capital markets. In turn, robust capital markets would help to mitigate the issue of overbanking and indirectly bolster banking consolidation. The issuance of Eurobonds would furnish the common safe asset essential for deepening these markets, while the digital euro would serve to reinforce European payment infrastructure and diminish reliance on foreign providers. Véron elaborates that "The banking union is a project of rationalising European banking into a single system instead of 27 national ones. That should in principle help to address the problem of overbanking, because this has partly to do with national fragmentation." He further posits that "Conversely, if you make capital markets more attractive and trustworthy, you could have rebalancing from banking intermediation to capital markets activity, which is needed to enhance the European economy’s growth potential."
Despite the considerable momentum behind deeper financial integration, Europe’s path toward financial sovereignty remains obstructed by a familiar array of entrenched barriers. Chief among these is the enduring influence of national interests, often manifested through lobbying efforts by national regulators, governments, and banks that perceive a threat to their influence within a more centralized system. The control of financial levers is a particularly sensitive issue, given the pivotal role financial institutions play in funding domestic industries. While fragmentation undeniably limits cross-border consolidation, impedes the development of deep capital markets, and complicates crisis management, national actors remain fundamentally reluctant to cede control to Brussels. Angeloni cautions that even if the Commission’s ambitious plans are up to the task, their ultimate effectiveness will hinge on their implementation. He questions whether they "will be diluted during implementation or delayed to the point of becoming untimely and ineffective." He concludes that "This will largely depend on political cohesion among the member states. Lack of cohesion has repeatedly hampered EU reform in the past." Historically, crises have served as the primary catalyst for European integration, from the eurozone debt turmoil to the recent pandemic. The current external pressures, including heightened geopolitical competition and the pressing need to finance large-scale investments, may again compel member states towards compromise. There is a discernible and growing awareness that the bloc is steadily losing ground in the global economic arena. Crucially, the Commission’s proposals do not necessitate unanimous consent but rather a qualified majority to advance. Ultimately, Brzeski asserts, integration is a means to a strategic end: closing the economic and financial gap with US markets. However, achieving this objective will inevitably require difficult compromises. He concludes that "If Europe really wants to become fully European, national preferences and partly national sovereignty would always have to take a step back."
