Large European banks call for further integration, but is it in consumers’ interests?

Those of a certain age may remember the fanfare which heralded the introduction of the Single European market (SEM) on 1 January 1993. It promised the removal of internal barriers to the movement of goods, services, capital and people. One sector that was noticeably absent from the single market, however, was banking.

Moves towards banking union only started after the global financial crisis in 2008. However, as a report published on the 2 September 2025 by the Association of Financial Markets in Europe (AFME) highlights, the institutional frameworks of banking in the EU are still deeply fragmented – the promised integration through the European Banking Union (EBU) is still incomplete. This has put European banks at a competitive disadvantage in global markets compared with rivals from the USA and Asia, thereby reducing their profitability and growth prospects. The report called on the European Central Bank (ECB) and national regulatory authorities to remove hurdles to cross-border banking services in the EU. This would enhance the strategic position of European banks.

In this blog we will trace the development of the EBU and analyse the current state of integration. We discuss the AFME proposals for achieving greater integration and highlight their benefits for large banks. We also analyse the barriers which limit full integration and examine the risks that retail customers might see few benefits from the proposed changes.

What is meant by European Banking Union (EBU)?

The 1993 Single European Market (SEM) in goods and services removed internal barriers to the movement of goods, services, capital and people within the EU. As part of this, there were harmonised standards and regulations for goods and services, no capital controls, mutual recognition of professional qualifications and common regulations on consumer protection, product safety, environmental protection and labour rights.

This integration of previously restricted domestic markets was designed to boost economic growth, employment and competitiveness by increasing trade and investment flows. Offering consumers greater choice would expose firms to greater competition. This would drive down prices and encourage greater efficiency and innovation. It has generally achieved these goals across many industries.

However, banking was excluded from integration. The 1985 White Paper, Completing the Internal Market, proposed the liberalisation of financial services, but banking remained regulated at the national level. This was influenced by interrelated economic, political and institutional forces, national sovereignty and political sensitivities, fragmented regulation and concerns about risk.

Even as the EU moved towards economic and monetary union (EMU) during the 1990s, there was no discussion of integration for the banking industry. However, that changed following the 2008 financial crisis and 2011 eurozone crisis. Both episodes exposed vulnerabilities in the EU banking system which required taxpayer support. It was proposed that deeper integration of the banking sector would ensure its stability and resilience. This stimulated moves towards European Banking Union (EBU), starting with the European Council agreeing its creation in 2012. There are three institutional pillars to the Union:

  1. The Single Supervisory Mechanism (2014) for systemically important financial institutions (SIFIs) ensures consistent oversight. SIFIs are banks with over €30 billion of liabilities or 20% of national GDP.
  2. The Single Resolution Mechanism (2016) manages the orderly resolution of failing banks with minimal costs to taxpayers. There is a central board for resolution decisions and a fund financed by the banking industry to support resolution actions.
  3. A European Deposit Insurance Scheme (still under negotiation) is proposed to protect depositors uniformly across the banking union against bank default.


The Union is intended to operate under a harmonised set of EU laws, known as the ‘Single Rulebook’, which includes implementing the BASEL III capital requirements, regulating national deposit insurance and setting rules for managing failing banks.

What is the state of integration at present?

Moves towards European Banking Union (EBU) have contributed to enhancing the resilience of the European banking system. This was one of its major objectives. European banks are much more secure having increased capital and liquidity levels, reduced credit risks and become less reliant on state-aid. They are also less profitable.

The AFME report points to remaining gaps in Banking Union which raise the cost for banks offering cross-border retail banking within the EU and limit the incentive to do so. The report identifies four such gaps.

1. Ring fencing.  Although there is a single supervisory mechanism for large systemically important institutions, since the financial crisis national regulators have implemented ‘ring-fencing’. This aims to protect retail banking activities from riskier investment banking. Ring-fencing retains liquidity, dividends and other bank assets within national borders to protect their retail banking sectors from contagion. The ECB estimates €225 billion of capital and €250 billion of liquidity is trapped by such national restrictions. Further, unharmonized and unpredictable use of capital buffers adds complexity for capital management at a multinational level. This particularly impacts large institutions. Banks’ cross-border activities are impeded since they are restricted in the way they can use capital and liquidity across the bloc.

The report argues that the stringent requirements of the ECB and the multiple layers of macroprudential requirements imposed at national level have led to an unnecessarily high level of capital. This disadvantages large European banks compared to their international competitors.

2. Impediments to cross-border M&As in banking within the EU.  This is due to cumbersome authorisation processes, involving multiple authorities at both national and supra-national level. Further, national authorities may interfere in the process of M&As in a bid to prevent domestic banks being acquired by ones from other parts of the EU. A recent example is UniCredit’s bid for Germany’s Commerzbank, which the German government opposes. These characteristics restrict opportunities for consolidation and efficiency gains for European banks.

The AFME report estimates that once eurozone banks grow beyond €450 billion in total assets, they suffer from negative synergies putting them at a competitive disadvantage to global competitors. Indeed, US banks are able to leverage scale economies from their domestic market to enter large EU markets. An example is JP Morgan’s entry into multiple EU markets through its Chase brand.

3. Contributions to the Single Resolution Fund (SRF) are complex and lack transparency.  This makes it difficult for banks to predict future commitments. The fund itself and its target level were determined at a time when banks had low buffers. Since then, European banks have raised their loss absorbing capacity and the AFME report proposes that further increases in contributions to the fund need to be carefully considered and reviewed.

4. The Deposit Guarantee Scheme remains unimplemented and there are still differences in national schemes.  This situation creates uncertainty for banks, which would like the European scheme for large systemically important institutions to be implemented fully.

These AFME proposals focus on the aspects of banking union which benefit large European institutions in their strategic competition with global rivals. These aspects would create ‘European’ banks as opposed to ‘national’ ones. This would give them the scale to be ‘champions’ in global competition. In particular, the large banks want lower capital requirements and the relaxation of national ring-fencing for retail banking to allow them greater freedom to achieve scale and scope economies across the bloc.

To what extent this will benefit retail customers, however, is debateable.

Will retail banking customers benefit?

Retail banking across Europe remains deeply fragmented, with significant price differentials from country to country. The following table illustrates pricing differentials for two retail products – loans and mortgages – across a sample of EU countries for July 2025.


The data show a range of average interest rates offered across the countries with a range of 5.03% for loans to households and 0.92% for new mortgages. These price differentials reflect a broad array of factors, not least the different institutional legal and risk characteristics of the national markets. They also reflect varying degrees of competition and the lack of cross-border trade in retail banking products. Retail banking remains a largely domestic industry within the EU. Cross-border banking services remain a marginal activity with non-domestic retail deposits rising by just 0.5% and non-domestic retail loans rising by just 0.3% between 2016 and 2024.

There are both natural and policy-induced barriers, which means that retail banking will remain largely segmented by nation.

On the demand-side, retail banking is largely a relational rather than a transactional service, with consumption taking place over a long time-period with significant financial risks attached. Even with deposit insurance and a lender of last resort (the central bank), consumers exhibit significant loss aversion in their use of retail banking services. Consequently, trust and confidence are important characteristics for consumers and that means they are likely to prefer to use familiar domestic institutions.

Further, perceptions about switching costs mean that consumers are reluctant to change suppliers. Such costs are exacerbated by language, cultural and legal differences between European countries, which can make the perceived costs of banking beyond national boundaries prohibitively expensive and create a preference for local institutions.

Consumer preferences can also create idiosyncratic market structures for retail banking services in particular countries. For instance, in several countries across the EU, notably Germany, mutualised credit unions account for significant shares of retail banking. This may limit the potential for foreign banks to penetrate Europe’s largest market.

There are also policy-induced obstacles to cross-border retail banking which operate on the demand-side. These include discriminatory tax treatment of foreign financial services which deters their purchase by consumers. Further, there are still eight different currencies used in the EU across the 27 member states (Denmark, Poland and Sweden are three significant examples). This creates costs and risks associated with currency exchange for consumers that may deter their use of cross-border deposits and loans. The full adoption of a single currency across the EU seems a long way off, which will limit the potential for a single banking market, particularly in the retail segment.

Retail banking as a public utility

Some argue that retail banking is a public utility and should be regulated as such. It has a simple business model, taking deposits, making payments and making loans. Like other utilities, such as water and energy, retail banking is an essential service for the smooth functioning of the economy and society. Like other utilities, bank failures create severe problems for the economy and society.

Since the financial crisis, stability in retail banking has been much more highly valued. In the period preceding the crisis, banks had used retail deposits to cross-subsidise their risky investment banking. The bank failures that resulted from this had severe economic consequences. The danger today is that by relaxing capital and liquidity restrictions too much, large banks may once again engage in risky behaviour, subsidised by retail banking – for example, by engaging in cross-border M&As. These may benefit their shareholders but provide little benefit to retail customers.

Further, allowing these large banks freedom to move funds around the bloc may lead to capital being concentrated in the most profitable markets, leaving less profitable markets / countries underserved. Retail banking, as a public utility, should be required to provide services there.

Who ultimately benefits?

The integration of banking services in the EU has progressed since the financial crisis, producing a more resilient system. However, there are features of retail banking which mean that integration which benefits consumers may be difficult to achieve.

Addressing the policy gaps identified by the AFME report may benefit large European banks by facilitating the scale economies to make them competitive internationally. However, until consumers are prepared, or able, to source banking services beyond national borders, they will see little benefit from European Banking Union (EBU) through lower prices and/or better service. The nature of retail banking in the EU suggests that this is unlikely any time soon.

Furthermore, since retail banking exhibits features of a public utility, regulators need to be wary of permitting the type of behaviour by large institutions which creates dangerous systemic risk. The worry is that, in the drive to create ‘European Champions’ in banking, regulators ignore the potential impact on retail customers.

The UK government announced on 14 October 2024 in a ministerial statement that it intended to raise the threshold for the ring-fencing (separation) of retail and investment banking activities of large UK-based banks. These banks are known as ‘systemically important financial institutions (SIFIs)’, which are currently defined as those with more than £25bn of core retail deposits. Under the new regulations, the threshold would rise from £25bn to £35bn.

Ring-fencing is the separation of one set of banking services from another. This separation can be geographical or functional. The UK adopted the latter approach, where ring-fencing is the separation of core retail banking services, such as taking deposits, making payments and granting loans to small and medium-sized enterprises (SMEs) from investment banking and international operations. The intention of ring-fencing was to prevent contagion – to protect essential retail banking services from the risks involved in investment banking activities.

Reducing regulation to increase competition

Raising the limit is intended to facilitate greater competition in the retail banking sector. In recent years, US banks, such as JP Morgan and Goldman Sachs, have been expanding their depositor base in the UK under their respective brands – Chase UK and Marcus.

These relatively small UK subsidiaries were not ring-fenced from their wider investment banking operations as their retail deposits were under (but not far under) the £25bn limit. However, this restricted their ability to increase market share further without bearing the additional regulatory burden associated with ring-fencing that much larger incumbents face. Raising the threshold would allow them to expand to the higher limit without the regulatory burden.

The proposals are part of a broader package of reforms aimed at reducing the regulatory burden on UK-based banks. The hope is that this will stimulate greater lending to SMEs to boost investment and productivity.

The proposals also include a new ‘secondary’ threshold. This will exempt banks providing primarily retail banking services from the rules governing the provision of investment banking accounts. This exemption will apply as long as their investment banking is less than 10% of their tier 1 capital. (Tier 1 capital is currently the buffer which banks are required to retain in case of a crisis.) The changes were the outcome of a review conducted in 2022 but had not been implemented by the previous government.

The announcement has sparked a debate about ring-fencing, with some commentators calling for it to be removed altogether. Therefore, it is timely to revisit the rationale for ring-fencing. This blog examines what ring-fencing is and why it was introduced, and explains the associated economic costs and benefits.

Why was ring-fencing introduced?

Ring-fencing was recommended by the Independent Commission on Banking (ICB) in 2011 (see link below) and implemented through the Financial Services (Banking Reform) Act of 2013. The proposed separation of core retail banking services from investment banking were intended to address issues in banks which arose during the global financial crisis and which required substantial taxpayer bailouts. (See the 2011 blog, Taking the gambling out of high street banking (update).)

Following deregulation and liberalisation of financial services in the 1980s, many UK banks had extended their operations so that they combined domestic retail operations with substantial investment and international operations. The intention was to open up all dimensions of financial services to greater competition and allow banks to exploit economies of scope between retail and investment banking.

However, the risks associated with these services are very different but, in the period before the financial crisis, were provided alongside one another within banking groups.

One significant risk which was not fully recognised at the time was contagion – problems in one dimension of a bank’s activity could severely compromise its ability to provide services in other areas. This is what happened during the financial crisis. Many of the UK banks’ investment operations had made significant investments in off-balance sheet securitised debt instruments – CDOs being the most famous example. (See the 2018 blog, Lehman Brothers: have we learned the lessons 10 years on?.)

When that market crashed in 2007, several UK-based banks incurred significant losses, as did other banks around the world. Given their thin equity buffers and the inability to borrow due to a credit crunch, such banks found it impossible to bear these losses.

The UK government had to step in to save these institutions from failing. If it had not, there would have been significant economic and social costs associated with their inability to provide core retail banking functions. (See the 2017 blog, Ten years on.)

The Independent Commission proposed that ‘the risks inevitably associated with banking have to sit somewhere, and it should not be with taxpayers. Nor do ordinary depositors have the incentive (given deposit insurance to guard against runs) or the practical ability to monitor or bear those risks’ (p.9). Unstructured banks, with no separation of retail from investment activities, increase the potential for both of these stakeholder groups to bear the risks of investment banking.

Structural separation of retail and investment banking addresses this problem. First, separation should make it easier and less costly to resolve problems for banks that get into trouble, avoiding the need for taxpayer bailouts. Second, structural separation should help to insulate retail banking from external financial shocks, ensuring that customer deposits and essential banking services are protected.

Problems of ring-fencing

Ring-fencing has been subject to criticism, however, which has led to calls for it to be scrapped.

It must be noted that most of the criticism comes from banks themselves. They state that it required significant operational restructuring by UK banks subject to the regulatory framework which was complex and costly.

In addition, segregating activities can lead to inefficiencies, as banks may not be able to take full advantage of economies of scope between investment and retail banking. Furthermore, ring-fencing could lead to a misallocation of capital, where resources are trapped in one part of the bank and cannot be used to invest in other areas, potentially increasing the risks of the specific areas.

Assessing the new proposals

It is argued that the increased threshold proposed by the authorities may put UK institutions at a competitive disadvantage to outside entrants that are building market share from a low base. Smaller entrants do not have to engage in the costly restructuring that the larger UK incumbents have. They can exploit scope economies and capital mobility within their international businesses to cross-subsidise their retail services in the UK which incumbents with larger deposit-bases are not able to.

However, the UK market for retail banking has significant barriers to entry. Following the acquisition of Virgin Money by Nationwide, only six banking groups in the UK meet the current threshold (Barclays, HSBC, Lloyds Banking Group, NatWest Group, Santander UK and TSB). Indeed, all of those have deposits well above the proposed £35bn threshold. Consequently, raising the threshold should not add significant compliance and efficiency costs, while the potential benefits of greater competition for depositors and SMEs could be a substantial boost to investment and productivity. Furthermore, if the new US entrants do suffer problems, it will not be UK taxpayers who will be liable.

Have we been here before?

In many ways, ring-fencing is a throwback to a previous age of regulation.

One of the most famous Acts of Congress relating to finance and financial markets in the USA is the Glass-Steagall Act of 1933. The Act was passed in the aftermath of the 1929 Wall Street crash and the onset of the Great Depression in the USA. That witnessed significant bank failures across the country and problems were traced back to significant losses made by banks in their lending to investors during the speculative frenzy that preceded the stock market crash of 1929.

To prevent a repeat of the contagion and ensure financial stability, Glass-Steagall legislated to separate retail banks and investment banks.

In the UK, such separation had long existed due to the historical restrictions placed on investment banks operating in the City of London. In the late 20th century, the arguments for separation became outweighed by arguments for the liberalisation of markets to improve efficiency and competition in financial services. Banking was increasingly deregulated and separation disappeared as retail banks increasingly engaged in investment activities.

That cycle of deregulation reached its nadir in 2007 with the international financial crisis. The need to bail out banks made it clear that the supposed synergies between investment and retail banking were no compensation for the high costs of contagion in the financial system.

Regulators must be wary of calls for the removal of ring-fencing. Sir John Vickers (chairman of the independent commission on banking) highlighted the need to protect depositors, and more importantly taxpayers, from risks in banking. It is the banks that should bear the risks and manage them accordingly. Ultimately, it is up to the banks to do that better.

HSBC is a familiar feature of many high streets in the UK and this is hardly surprising, given that it is the largest bank in Europe. But could this be about to change? With uncertainty surrounding the UK’s in-out vote on the EU, the future of the banking levy and HSBC’s desire to reduce the size of its operations, the UK high street might start to look quite different.

In the UK, 26,000 staff are employed in its retail banking sector, with 48,000 workers across the whole of its UK banking operations. HSBC has plans to downsize its business globally, with expected job losses in the UK of 8000 workers and a total of 25,000 jobs across the world. This would reduce its workforce by around 10%. This could have big implications for the UK economy. Although many of the job losses would not be enforced, given that HSBC does have a relatively high staff turnover, it is likely to mean some forced redundancies. With job creation being one of the big drivers of the UK economy in the last couple of years, this could put a dampner on the UK’s economic progress.

A further change we are likely to see will be the renaming of high street branches of HSBC, as new government rules are requiring HSBC to separate its investment and retail banking operations. Much of this stems from the aftermath of the financial crisis and governments trying to reign in the actions of the largest banks. Ring fencing has aimed to do this as a means of protecting the retail banking sector, should the investment banking part of the bank become problematic.

However, perhaps the biggest potential shock could be the possibility of HSBC leaving the UK and moving to a new base in Hong Kong. A list of 11 criteria has been released by HSBC, outlining the factors that will influence its decision on whether to stay or go.

The UK’s decision on Europe is likely to be a key determinant, but other key factors against remaining in the UK are ‘the tax system and government policy in support of [the] growth and development of [the] financial services sector’. HSBC pays a large banking levy, as it is based not just on UK operations, but on its whole balance sheet.

HSBC’s Chief Executive, Stuart Gulliver, has said that the discussion on the potential move to Hong Kong is based on the changing world.

“We recognise that the world has changed and we need to change with it. That is why we are outlining the following… strategic actions that will further transform our organisation… Asia [is] expected to show high growth and become the centre of global trade over the next decade… Our actions will allow us to capture expected future growth opportunities.”

Leaving the EU will have big effects on consumers and businesses, given that it is the UK’s largest market, trading partner and investor. Whether or not decisions of key businesses such as HSBC will have an impact on the referendum’s outcome will only be known as we get closer to the day of the vote (which is still some way off!). It will, however, be interesting to see if other companies raise similar issues in the coming year, as the referendum on the EU draws nearer. We should also look out for any potential change in the UK’s banking levy and what impact, if any, this has on HSBC’s decision to stay or go and on the future of any other banks.

On 15 September 2008, Lehman Brothers, the fourth-largest investment bank in the USA, filed for bankruptcy. Although the credit crisis had been building since mid 2007, the demise of Lehmans was a pivotal event in the unfolding of the financial crisis and the subsequent severe recession in most developed economies. Banks were no longer seen as safe and huge amounts of government money had to be poured into banks to shore up their capital and prevent further bankruptcies. Partial nationalisation seemed the only way of rescuing several banks and with it the global financial system.

A deep and prolonged recession followed (see Chart 1: click here for a PowerPoint). In response, governments pursued expansionary fiscal policies – at least until worries about rising government deficits and debt caused a lurch to austerity policies. And central banks pursued policies of near zero interest rates and subsequently of quantitative easing. But all the time debate was taking place about how to reform banking to prevent similar crises occurring in the future.

Solutions have included reform of the Basel banking regulations to ensure greater capital adequacy. The Basel III regulations (see Chart 2) demand considerably higher capital ratios than the previous Basel II regulations.

Other solutions have included proposals to break up banks. Indeed, just this week, the Lloyds Banking Group has hived off 631 of its branches (one sixth of the total) into a newly reformed TSB. Another proposal is to ring-fence the retail side of banks from their riskier investment divisions. In both cases the aim has been to avoid the scenario where banks are seen as too big to fail and can thus rely on governments to bail them out if they run into difficulties. Such reliance can make banks much more willing to take excessive risks. Further details of the new systems now in place are given in the Robert Peston article below.

But many critics maintain that not nearly enough has been done. Claims include:

• The Basel III rules are not tough enough and banks are still being required to hold too little capital.
• Rewards to senior bankers and traders are still excessive.
• The culture of banking, as a result, is still too risk loving in banks’ trading arms, even though they are now much more cautious about lending to firms and individuals.
• This caution has meant a continuing of the credit crunch for many small businesses.
• Higher capital adequacy ratios have reduced bank lending and have thus had a dampening effect on the real economy.
• The so-called ring-fences may not be sufficient to insulate retail banking from problems in banks’ investment divisions.
• Banks are not being required to hold sufficient liquidity to allow them to meet customers’ demands for cash in all scenarios.
• Banks’ reliance on each other still leaves a systemic risk for the banking system as a whole.
• Fading memories of the crisis are causing urgency to tackle its underlying problems to diminish.
• Problems may be brewing in less regulated parts of the banking world, such as the growing banking sector in China.
