EBA — Guardian of the Banking Layer
Europe wants deeper capital markets and less dependence on bank lending. But banks remain embedded throughout its financial system. Can Europe broaden the architecture without weakening the banking layer underneath it?
GUARDIAN FILE — Europe’s capital-market project is often described as a move away from bank dependence. That is only partly true. Innovative companies need more equity, deeper bond markets and larger pools of risk capital because banks cannot finance every stage of growth. But banks remain lenders, intermediaries, investors and gateways into markets. Building deeper capital markets therefore does not make the banking layer disappear. It changes what Europe needs that layer to do.
That makes the European Banking Authority — EBA — an important Guardian. The ECB, examined in the previous Guardian File, safeguards monetary and financial stability and directly supervises significant banks within the banking union.
EBA performs a different task. It helps create the common prudential language through which banks across the wider EU Single Market can operate under sufficiently consistent rules, even when their supervisors, business models and national financial systems remain different.
Europe therefore faces a paradox. It wants capital markets to carry more risk. But it still needs banks strong enough to finance the economy, connect companies with markets and absorb shocks without becoming the source of the next crisis.
The question is not whether Europe needs banks or capital markets. It is what kind of banking layer a deeper capital market requires.
🟦 Can Europe build deeper capital markets without changing the role of its banks?
Europe’s Savings and Investments Union begins from a familiar diagnosis: companies need more financing alternatives, particularly when innovation and rapid growth require forms of risk capital that traditional bank balance sheets are poorly suited to provide. But broadening the financial system is not the same as replacing its banks.
Banks remain deeply embedded in Europe’s capital architecture. They lend directly to households and companies, but they also help businesses issue securities, provide liquidity, distribute financial products and connect borrowers with investors. The relationship between banks and markets is therefore not simply competitive.
Capital markets can carry risks that prudentially regulated bank balance sheets should not carry alone. Banks, in turn, provide forms of credit, intermediation and financial infrastructure that markets cannot simply reproduce. Europe’s transition is therefore about rebalancing functions.
For decades, banks carried an unusually large share of European economic financing. Deeper capital markets should reduce that concentration. But they will not make banks less important.
The goal is not to move beyond banking. It is to move beyond a system in which banking has to carry almost everything.
🟦 If the ECB supervises the banking union, who keeps the banking layer coherent across the whole Single Market?
This is where the distinction between ECB and EBA becomes crucial. The ECB directly supervises significant banks within the participating countries of the banking union. EBA confronts a broader geographical problem: its Single Rulebook and supervisory-convergence work extend across the entire EU financial market. That includes Member States outside the euro area and outside ECB Banking Supervision.
Banks in Sweden, Denmark or Poland still operate inside the same European Single Market. Their customers, investors and counterparties increasingly interact across borders. Their prudential framework therefore cannot diverge so far that Europe effectively develops different banking systems for those inside and outside the banking union.
EBA helps bridge that institutional boundary. It develops common prudential standards, promotes supervisory convergence and provides methodologies through which authorities can assess risks more consistently across Europe. That does not mean every bank should be supervised identically.
National banking systems differ. Credit cycles differ. Housing markets, corporate financing structures and business models differ. But common markets require a sufficiently common language.
The banking union is not the whole Single Market. EBA is one of the institutions that keeps the two connected.
That makes its role more architectural than supervisory in the narrow sense. EBA does not need to sit inside every bank. It needs to ensure that Europe’s distributed banking layer remains intelligible across borders.
🟦 Can Europe make its banks safer without making them too cautious to finance its future?
This is perhaps the central prudential tension. Europe strengthened its banking framework for good reason. The financial crisis demonstrated what happens when leverage, liquidity risk and weak supervision accumulate inside interconnected institutions.
Capital requirements, liquidity standards and stress testing are therefore not obstacles sitting outside the financial system. They are part of the infrastructure that makes the system credible. But resilience has consequences.
A bank financing an established company with predictable revenues is taking a different kind of risk from an institution backing a new technology, an unfamiliar market or a company whose value depends on future growth. This is one reason Europe needs deeper capital markets. Banks should not be forced to behave like venture-capital funds simply because Europe wants more innovation finance.
At the same time, prudential regulation should not unintentionally make banks incapable of supporting productive investment or participating in mechanisms that connect borrowers with capital markets. That tension is becoming particularly visible as Europe implements the final Basel III reforms through CRR III and CRD VI. Global prudential standards demand resilience.
European policymakers simultaneously want competitiveness, proportionality and greater financing capacity. EBA sits close to that translation.
Resilience may be global. Economic structures remain European. The two still have to coexist.
The danger lies at both extremes. A banking system permitted to take excessive risk eventually destabilises the economy. A banking system designed to avoid almost every difficult risk can become economically defensive. The Guardian therefore protects resilience without turning prudence into paralysis.
🟦 Can banks become bridges into capital markets rather than alternatives to them?
This may be the most important shift in how Europe thinks about banking. Bank finance and capital-market finance are often presented as competing models. In practice, they can reinforce one another. Securitisation offers perhaps the clearest example.
A bank originates loans. Those loans can be pooled into securities and transferred to investors in the capital market. Risk moves beyond the bank balance sheet, while capital can be released for new lending.
The bank remains important. But it no longer has to retain every risk it originates for the entire life of the loan. That turns the bank into an interface between traditional credit and capital markets. It also exposes the prudential dilemma with unusual clarity.
Too little transparency or risk discipline can recreate the opacity that made securitisation notorious during the global financial crisis.
Too much capital burden or regulatory complexity can make the mechanism economically unattractive and prevent the market from developing at all.
The bank-to-market interface therefore has its own prudential boundary.
EBA matters because common technical standards, supervisory approaches and interpretations help determine whether that boundary remains credible across Europe.
The objective is not simply to revive securitisation. It is to allow banks and markets to perform complementary functions without allowing risk to disappear into structures that supervisors can no longer understand. That is a very different vision from replacing banks with capital markets. Banks can increasingly become bridges into those markets.
🟦 Where should common prudential rules end — and local supervisory judgement begin?
Every Guardian in this series eventually reaches the same institutional question. Where should its authority stop? For EBA, that boundary lies between common rules and legitimate local judgement.
A European Single Rulebook is necessary because banks operate inside an interconnected market. Investors and counterparties need confidence that the same basic prudential principles apply across jurisdictions. But common rules encounter different realities.
A mortgage market in one Member State is not identical to one elsewhere. SME lending structures differ. Banks have different funding models, customer bases and economic environments. Supervisory convergence therefore cannot mean pretending those differences do not exist.
Identical rules still have to encounter different local credit realities.
This is why EBA’s role cannot simply be reduced to uniformity. Its task is to ensure that legitimate differences do not become regulatory loopholes, supervisory arbitrage or inconsistent treatment — while preserving enough judgement for national supervisors to understand the institutions and markets closest to them. That requires restraint as much as harmonisation.
EBA should not decide which sectors banks finance. It should not convert prudential standards into industrial policy. And it should not eliminate useful differences merely because uniformity is administratively simpler. The objective is coherence. Not sameness.
Guardian
Europe’s attempt to deepen its capital markets does not make the banking layer obsolete. It makes its role clearer.
Companies will need more equity and long-term risk capital. Public markets will need to become deeper. Institutional investors will need better pathways into productive investment. But businesses will still borrow. Households will still hold deposits.
Banks will still provide credit, liquidity and intermediation — and increasingly help connect those activities with securities markets.
EBA guards the framework within which that banking layer operates. Not by supervising every institution directly, and not by determining where banks should allocate capital, but by helping the European banking system speak a common prudential language across the Single Market.
That is why its role remains important even as Europe tries to reduce its dependence on bank lending.
A broader financial architecture does not require a weaker banking layer. It requires a banking layer that understands its place within a larger system.
That leaves the Guardian with a characteristically European challenge. Too much fragmentation undermines the Single Market. Too much uniformity can ignore the economic diversity underneath it. And excessive caution can become as structurally limiting as excessive risk-taking.
Can Europe make its banking layer European enough to support one financial architecture — while keeping it flexible enough to finance twenty-seven different economies?
