Banking consolidation has become a hot topic as we enter an environment increasingly supportive of such strategic objectives. However, skepticism persists, driven by rising concerns over systemic risk, reduced competition, and integrative challenges. The UniCredit–Commerzbank case has remained a central topic of discussion amidst the shifting landscape. In this article, we examine the macroeconomic landscape of the sector, and explore the rationale behind the ongoing discussions around the potential deal, analysing strategic evolutions, restructuring shifts, and regulatory & political barriers.

I. Macro Context – Why consolidation in the European banking sector
​
In recent years, the European banking landscape has undergone a notable shift, bringing consolidation to the forefront of strategic and policy discussions. This shift is occurring within a macro context defined by improved profitability, stronger capital positions, and growing competitive pressure, but also persistent structural fragmentation and regulatory complexity. 

​The European banking sector is currently highly fragmented along national lines. Despite the existence of the European Banking Union, which is designed to unify initiatives, retail and commercial banking activities remain predominantly domestic, with limited cross-border integration. This is largely attributable to differences in national regulation, legal systems, taxation, and supervisory practices, that continue to act as barriers to a truly unified market. As a result, European banks operate in a structurally segmented environment that limits scale efficiencies and suppresses valuations relative to global peers, and which explains why consolidation has become increasingly domestic.

​In recent years, banks have actively pursued domestic deals and “bolt-on” acquisitions to reduce costs, improve efficiency, and gain scale, with particularly strong activity in countries such as Italy. Conversely, large pan-European transactions continue to face significant political resistance and national protectionism, as governments seek to safeguard domestic institutions viewed as strategic assets. As a result, while national banking systems are becoming more concentrated, the broader European market remains fragmented.

​Meanwhile, the macro environment has become more supportive of consolidation. Following a prolonged period of low profitability, European banks are benefiting from the current high interest rate environment, which has significantly boosted net interest income. ROE has recovered to approximately 9-10%, while capital ratios have reached historically high levels. This improvement has strengthened balance sheets and provided banks with a stronger capital position, enabling a shift from defensive restructuring towards more proactive, efficiency-driven M&A strategies.

​This shift is also reflected in changing strategic positions. Banks are increasingly pursuing acquisitions for reasons other than cost synergies, to diversify revenue streams and reduce reliance on net interest income. At the same time, the increasing importance of digitalization, AI, cybersecurity, and real-time infrastructure is raising the minimum efficient scale required to compete. Such rising technology investment costs are creating further incentives to consolidate and share these burdens across larger entities. Policymakers have also begun to change their approach; European authorities and the ECB are progressively viewing consolidation as a tool to enhance the resilience and competitiveness of the banking system. Recent initiatives to simplify regulation, harmonize rulebooks, and advance the Savings and Investment Union, a European Commission with the aim to create a financial ecosystem supportive of the EU’s investments and strategic objectives, reflect the effort to reduce structural barriers and encourage cross-border integration. However, despite these supportive forces, there exists significant obstacles that continue to constrain consolidation. Political intervention is a key barrier, as national governments frequently oppose foreign acquisitions of domestic banks. Moreover, cross-border transactions are often associated with high execution risk, lengthy approval processes, and complex integration due to differences in IT systems, corporate cultures, and legal structures. Together, these factors collectively position incentives towards domestic deals rather than pan-European ones.

​Nevertheless, policy debates should continue supporting the integration of the EU banking sector. In this regard, the Draghi report provides clear evidence of the need for larger and stronger European banks. The current fragmentation of the financial system puts a strain of capital flow within the Union, limiting investments and putting a cap on growth potential. With lower integration, banks are less willing to engage in cross-border lending operations, resulting in a “home bias” where most of the assets are invested within national borders. This phenomenon is even more problematic considering that EU companies rely much more on bank financing compared to international competitors. Furthermore, Draghi largely attributes the lack of scalability and profitability of EU banks to the incomplete Banking Union.

​However, even though the Draghi report has set a benchmark on the issue and promoted  policy discussions, most of its proposals have been only partially implemented, highlighting how real progress is still limited. To improve capital allocation, the EU has launched initiatives to channel households’ savings into investments on strategic goals like digital innovation, which are likely to provide higher return compared to low-interest bank deposits. Even so, the Banking Union is still fragmented, and many look at the European Deposit Insurance Scheme (EDIS) as the missing piece of the puzzle. The EDIS would ensure that bank deposits are equally protected across member states, regardless of the bank’s nationality. The creation of a shared European fund to guarantee deposits would reduce dependence on domestic governments, enhance financial stability and relax the bank-sovereign link.

​While the US has historically dominated in profitability and scale, European banks have recently closed the performance gap, exhibiting a strong comeback in 2025 and projecting continued competitive strength. Nevertheless, a structural gap remains, especially in valuations, market fragmentation, and capital market depth, where the US stays ahead. More specifically, the profitability gap is narrowing, with European banks witnessing ROE surge to 12.3% in Q2 2025, temporarily outperforming US peers who averaged 11%. For full-year 2025, US ROE was estimated at 11.6% vs 9.8% for Europe, showing Europe's significant progress in performance. Despite such advancements, European banks remain undervalued compared to their US peers. This data can be attributed to a more fragmented EU market composed of smaller institutions, who also have less access to capital markets, private equity, and venture capital than their US peers. Together, these trends point toward a greater role for M&A in addressing the structural fragmentation of the European banking sector.

​Overall, consolidation in European banking is progressing, but unevenly. Domestic deals are accelerating, supported by strong capital positions and strategic initiatives, while cross-border integration remains constrained by structural and political barriers. The result is an increasingly concentrated, yet still fragmented, landscape, however a fully integrated European banking market has yet to be achieved.

II. UniCredit Strategy as a case study for European consolidation

UniCredit has been, without any doubt, Italy’s most active player in the current wave of banking consolidation. Since late 2024, the bank has pursued three parallel M&A initiatives across Italy, Germany and Greece, signalling a shift from post-crisis restructuring to a more assertive, expansion-driven strategy.

The track record

The Italian leg began in November 2024, when UniCredit launched a roughly €15bn all-share offer for Banco BPM. The bid was conceived as a domestic consolidation play, but it ran into the Italian government's "golden power" regime in April 2025: citing UniCredit's residual Russia exposure on national-security grounds, Rome attached conditions including a Russia exit, regional lending floors and CET1 maintenance requirements. The European Commission separately challenged Rome's use of the golden power, raising the prospect of a future revival, though no concrete signal of one has been given.

​The German leg has been longer and more visible. UniCredit took an initial 9% stake in Commerzbank in September 2024 and built it up over fifteen months to roughly 28%, partly in physical shares, partly through total return swaps. In March 2026 it launched an exchange offer at 0.485 UniCredit shares per Commerzbank share, implying a ~4% premium, designed in such a way as to allow a stake increase past the 30% mandatory-bid threshold without seeking outright control. Commerzbank's management characterised the move as hostile, and Chancellor Friedrich Merz publicly opposed it; the German federal government remains a roughly 12.7% shareholder. On 7 April 2026 the target's board formally rejected the offer, citing insufficient value creation.

​UniCredit reached a directly held 29.8% in Alpha Bank by January 2026, with further instruments potentially lifting the position to roughly 32%. The stake has been equity-consolidated and is expected to contribute close to €244m of net profit in 2026, with the Greek authorities openly supportive throughout.

Why Commerzbank: rationale and timing

The strategic rationale rests on complementarity. UniCredit already owns HypoVereinsbank, giving it an established southern-German retail and corporate base; Commerzbank brings Mittelstand corporate relationships and a stronger position in northern Germany. Orcel's stated case is that a combined entity could unlock around €1.1bn of value by 2030 and lift Commerzbank's 2028 net income by roughly €600m versus its standalone path. The transaction would also create one of the eurozone's three largest banks by assets, partially closing the scale gap with US peers.

The reasons it has not materialised are mostly non-economic. German political opposition is the binding constraint, both at federal level and within Commerzbank's labour-side board representation. The capital arithmetic also matters: : Orcel has indicated that moving to 100% would absorb around 200bps of CET1, and a control stake near 40% would likely trigger a mandatory cash buyout of minorities in the Polish subsidiary mBank, further straining capital. Yet the deal is not dead. UniCredit's current stake is reportedly generating a return on investment around 20%, well above its cost of equity, and the structure of the latest bid leaves the door open for a more cooperative approach later, Orcel has explicitly described an 18-month "separate and distinct" period before any integration would be considered.

​Orcel's approach

The pattern across the three campaigns is consistent: build a meaningful equity position first, equity-consolidate to capture earnings, and only escalate to a full bid when the capital math and the political environment both clear. Similar to BNP Strategy in France the approach is for sure to consolidate within the European environment that is certainly creating fear of missing the chance to lead a EU without the UK presence (i.e HSBC and Barclays).

Bottom line:

​UniCredit's strategy is best read as selective and return-driven rather than expansion-driven. A pan-European group remains a possible destination, but the path is being walked stake by stake, not deal by deal.

III. Company Analysis – Unicredit and Commerzbank

Building on the view that UniCredit’s strategy is selective and return-driven, the debate around UniCredit’s approach to Commerzbank has shifted from one of potential to one of necessity. The industrial logic of the transaction still broadly holds, but the evolution of both banks has changed the way that logic should be assessed. The question is no longer simply whether a combination could create value in principle, but whether it remains the best use of capital given the progress UniCredit has made on its own.

​UniCredit’s financial trajectory has been central to that shift. Over the past year, the bank has sustained the profitability gains achieved under the current rate environment while maintaining a strong focus on costs and capital discipline. Return on equity has remained in the low-to-mid teens, and capital levels have stayed comfortably above regulatory thresholds. More importantly, UniCredit has shown that it can generate attractive returns without relying on large-scale acquisitions. Its stake in Commerzbank already produces meaningful value, which lowers the urgency of pursuing full control.

​Commerzbank has also improved, but in a more measured way. Profitability has recovered and capital ratios remain solid, yet returns still lag UniCredit’s and remain more volatile. Its strength in the German domestic market, particularly in servicing the Mittelstand, provides a stable franchise, but also limits diversification and broader growth opportunities. At the same time, the improvement in its standalone performance has made the bank less clearly vulnerable and more willing to defend its independence.

​That divergence reflects a wider gap in strategic execution. UniCredit has pursued a disciplined, return-driven model, deploying capital selectively and showing a willingness to step back when conditions do not justify further escalation. Commerzbank, by contrast, remains more constrained by its domestic focus and by the need to balance commercial priorities with political considerations, given the German state’s continued presence as a shareholder. In practice, this has left UniCredit with greater flexibility and stronger optionality.

​
​As a result, the balance of strength has shifted further in UniCredit’s favour. It generates higher and more consistent returns, has a broader geographic platform, and can already monetise strategic positions without committing to full integration. That is a meaningful change. Earlier, a full transaction could be seen as a natural next step in UniCredit’s strategic expansion. Now, it looks more like one option among several, rather than a necessary move.

​Even so, the industrial logic of a merger remains credible. The two banks are complementary rather than overlapping. UniCredit brings scale, capital strength, and a pan-European platform. Commerzbank adds a strong German corporate franchise and deep relationships with mid-sized firms in Europe’s largest economy. A combined group would therefore expand both geographic reach and client coverage in a way that is strategically coherent.

​There is also enough alignment in their business models to support an integration case. Both banks are centred on commercial and corporate banking, both rely heavily on relationship-based lending, and both have undergone restructuring aimed at improving efficiency and capital discipline. Compared with many cross-border transactions, this gives the deal a more coherent industrial basis.

​The potential synergies, however, are more strategic than cost-driven. A combination could allow UniCredit to extend Commerzbank’s client relationships beyond Germany while strengthening its own position in a core European market. Some cost benefits may emerge through overlap in systems and support functions, but these are unlikely to be the main source of value. The more important issue is whether full control adds enough incremental benefit to justify the execution risk and capital commitment.

​That is where the case becomes less clear-cut. UniCredit can already participate in Commerzbank’s upside through its existing stake, without assuming the complexity of full ownership. From this perspective, the UniCredit-Commerzbank case fits within the broader trajectory of European banking consolidation. The industrial logic for the cross-border scale remains intact in a structurally fragmented market, but execution continues to be shaped by national barriers and regulatory complexity. Within that environment, UniCredit stands out as an active participant, using a disciplined and incremental strategy to navigate these constraints.

IV. Regulation & Politics 

In this framework, cross-border mergers between EU banks have reached a total deal value of $17bn in 2025, their highest level since 2008. The rise in the EU banking deals has likely been favoured by higher sector valuations, lower defaults and higher benefits of large-scale IT investments. Strongly advocated by policymakers as a means of diversification and better use of scale, integration of pan-EU banking is, however, progressing slowly. Nevertheless, many supporters hope for further improvements, including the UniCredit chief Andrea Orcel, who stated that “the competitive landscape is going to change”, with fewer and larger players.

​The current geopolitical risks and economic uncertainty are increasingly showing the need to strengthen the integration of the Single Market and enhance the banking integration, a key objective of the EU banking union. Although still incomplete, the Banking Union provided a sound regulatory framework and more harmonized supervision, fostering European banks' resilience to recent shocks, including Covid-19 pandemics and energy crisis.

German Stance on the UniCredit-Commerz Deal

At the same time, greater integration of the banking system can cause local shocks to result in negative spillovers across the EU. Countries with sound banking systems worry about sharing risks with more exposed regions. In this context, the German government continues showing concerns over Italian sovereign debt exposure, and its political stance on foreign bank control has not meaningfully shifted. In May of last year, Chancellor Merz was playing down the risk of a takeover, claiming that UniCredit's stake was "below the threshold at which it would have to make a takeover offer" and that it was unclear whether this threshold would have been exceeded.

​However, the circumstances changed when UniCredit formally launched its €35 billion bid in March of this year. Considering the offer "unacceptable", the German Chancellor reinforced the government's stance on Commerzbank as an independent entity, with the government remaining Commerzbank's second-largest shareholder and labour unions continuing to oppose the deal. It is worth noting that Germany acknowledges the need of larger European banks and Berlin is not opposed to European banking consolidation in the abstract. However, it draws a sharp distinction between a negotiated, consensual deal and a hostile cross-border takeover of a national champion, a distinction that gives it a near-permanent veto.

Comparative Analysis with the US Regulation

The contrast between the EU and US banking systems is sharp, and it provides evidence of why cross-border consolidation in Europe is stuck. In 1994, the US passed an act aimed at removing many of the restrictions on opening bank branches across state lines, providing a uniform set of federal rules to follow. As a result, rapid cross-state consolidation occurred and the country saw the emergence of large and nationally integrated banks operating under a single supervisory and framework.

​Despite sharing a single currency, the EU has never achieved anything equivalent. EU banks face almost twice the contributions to deposit and resolution funds compared to US peers. Moreover, requirements on bail-in-able capacity (the amount of a bank’s liability that can be written down or converted into equity) are 3.9 percentage points higher than in the US. These are structural cost disadvantages for the EU and help explain why the largest US bank, JPMorgan, has a market capitalization that is larger than the ten bigger EU banks combined. The EU's regulatory architecture is also far more layered. Since the financial crisis, the EU has created new regulatory and supervisory bodies whose roles sometimes overlap, compete and tend to favour caution. This results in a fragmentation that is probably the most important constraint of EU bank performance. Moreover, we must remember that the US federal law is supreme over all state laws, making it easier to implement uniform standards than in the EU, where the final say is determined by national political entities.

​To understand whether the US system could be looked at as a model, we should consider the following. On one hand, the American system shows that top-down deregulation of geographic restrictions, when implemented with a unified supervisory, can result in rapid consolidation. An analysis published in April 2025 in the Journal of Financial Regulation offers precisely such a parallel, arguing that "eliminating regulatory and institutional barriers to interstate banking consolidation must become a priority" for the EU, as interstate consolidation offers greater financial stability through diversification, improved efficiency and enhanced global competitiveness, crucial objectives of the Union. The critical warning, however, is that the US achieved this through a federal political system capable of overriding state resistance. The EU lacks that override mechanism: completing the banking union still requires unanimous agreement among sovereign states on deposit insurance, which is why the analogy remains aspirational rather than immediately actionable. Despite these differences, the EU can take concrete steps to overcome its fragmentation. This includes, for instance, harmonizing legal frameworks to reduce the complexity and cost of cross-border operations and introducing the long-proposed European Deposit Insurance Scheme. Furthermore, strengthening capital markets integration to facilitate intra-EU capital investment flows could be regarded as another path to favour the desired integration.

Open Strategic Autonomy and Current Deal Barriers

The UniCredit-Commerzbank case is a clear test of how "open strategic autonomy" functions when theoretical principles meet a real cross-border deal, with the result being rather unfavourable to integration. On the regulatory side, the picture is mixed but broadly supportive: in March 2025, the ECB granted UniCredit authorization to acquire a direct stake of up to 29.9% in Commerzbank, proving that EU-level supervisors are not the obstacle. However, several further approvals remained required before the roughly 18.5% of shares held through derivatives could be converted into physical shares.

​On the political side previously discussed, Berlin did not soften its position once a new government was formed. In early 2026, UniCredit became Commerzbank's largest shareholder in March 2026, holding roughly a 28% stake and is now trying to push its stake past 30%, the threshold triggering a mandatory public offer under German law. Commerzbank's board rejected the takeover offer of €35 billion, and UniCredit responded in April 2026 by taking its case directly to shareholders, providing evidence for a significant combined net profit in case of acquisition. In this setting, UniCredit argues Commerzbank is overvalued and underperforming, while Commerzbank formally rejected the offer as delivering insufficient value and lacking mutual trust.

V. Conclusion

The UniCredit-Commerzbank case shows a paradox of open strategic autonomy in the banking sector. The EU's institutions call for cross-border scale as a geopolitical need, but the levers of resistance, including government shareholdings, national antitrust reviews, and  labour opposition, remain at the national level, where the strategic autonomy argument gets quietly inverted to protect the status quo. This tension is unlikely to be resolved in the near future, even though the structural incentives for consolidation are tangible: rising technology costs, persistent valuation discounts and a competitive gap with US peers that no single domestic deal can close. At the same time, the political architecture of the EU continues to favour restraint over ambition, a fact that may protect incumbents under the pretext of stability. UniCredit's stake-by-stake approach may prove to be the most rational response to this environment, but whether that is enough to actually reshape the European banking landscape remains an open question.
