What can ASEAN learn from Europe’s capital market integration? 

ASEAN is seeking to deepen capital market integration in order to mobilise regional savings for investment, reduce reliance on extra-regional financing, and strengthen resilience to external shocks. This agenda has gained urgency amid heightened geopolitical tensions and a shifting global economic order in which middle powers are increasingly pursuing greater strategic and financial autonomy.

The ASEAN Capital Markets Forum (ACMF) Action Plan 2026–2030 has arrived at a pivotal moment. While ASEAN’s capital markets have expanded significantly over the past two decades, structural barriers continue to constrain cross-border investment. Fragmented market infrastructure, regulatory divergence, and uneven investor protection frameworks continue to constrain the scale and efficiency of regional capital flows.

Advancing integration will require reforms that preserve national regulatory autonomy while strengthening regional cooperation. Policymakers will also need to respond to powerful structural forces shaping global finance, including digitalisation, sustainability-driven investment, and the diversification of capital sources.

Europe’s long and extensive experience in capital market integration offers useful insights for ASEAN as it navigates these challenges. While the EU’s institutional framework is unique, its evolution illustrates how regional markets can gradually align regulatory standards, strengthen supervisory coordination, and deepen financial integration while balancing national sovereignty.

How has the EU’s approach to capital market integration evolved? 

Europe’s approach to capital market integration has developed gradually since the 1957 Treaty of Rome, with progress often advancing in response to economic pressures or financial crises. It was the free movement of capital, a Treaty requirement, that launched the first efforts in financial services in the early 1990s through the Investment Services Directive. Early efforts focused primarily on aligning regulatory rules to support the creation of a common market, while supervision remained largely the responsibility of national authorities.

As cross-border financial activity expanded, policymakers recognised that harmonised rules alone were insufficient to support integrated markets. Stronger coordination between national supervisors became necessary. Reforms in the early 2000s sought to promote convergence in supervisory practices, but the global financial crisis ultimately exposed the limitations of a fragmented oversight framework.

In response, the EU strengthened its institutional architecture for financial supervision through the De La Rosière reforms. One major development was the creation of the Single Supervisory Mechanism (SSM), under which the European Central Bank (ECB) directly supervises approximately 110–120 of the euro area’s largest and most systemically important banks, representing the majority of banking assets in the euro area. Smaller institutions — roughly 2,000 banks — remain supervised by national authorities within a common supervisory framework coordinated by the ECB. The European Systemic Risk Board (ESRB) was created directly as a result of the recommendations in the de Larosière Report, and is one of the first dedicated macro-prudential authorities in the world.

Alongside this reform, the EU established three sectoral supervisory bodies: the European Banking Authority (EBA), the European Insurance and Occupational Pensions Authority (EIOPA), and the European Securities and Markets Authority (ESMA). These authorities were designed to strengthen regulatory coordination by developing common standards, promoting supervisory convergence among national regulators, and improving cross-border cooperation across Europe’s financial system.

Within Europe’s capital markets, ESMA plays a central role in regulatory coordination and supervision. It develops regulatory technical standards, promotes supervisory convergence across national authorities, and exercises direct oversight in specific areas such as credit rating agencies and trade repositories. Overtime ESMA’s responsibilities have expanded as the EU has sought to strengthen the consistency, credibility, and resilience of capital markets supervision in response to financial crises, deeper market integration, and the emergence of new risks such as climate change and digital assets.

To further enhance ESMA’s mandate, it is widely anticipated that the President of the European Commission will announce that ESMA’s direct supervisory powers will be enhanced by the end of this year, while introducing an independent Executive Board to enhance governance akin to the SSM.

Parallel to these institutional reforms, the EU launched the Capital Markets Union (CMU) initiative to address persistent fragmentation across European capital markets. CMU seeks to improve access to market-based financing, deepen cross-border investment, and mobilise Europe’s substantial pool of household savings for productive investment. More recently, this agenda has evolved toward a broader Savings and Investments Union, reflecting renewed political focus on strengthening Europe’s capital markets as a source of economic resilience.

Europe’s experience illustrates that financial integration is inherently gradual. Institutional development, regulatory convergence, and market integration tend to evolve incrementally, shaped by political compromise, market developments, and the practical realities of aligning diverse financial systems.

What were the EU’s ingredients for success? 

Europe’s experience highlights several factors that supported progress in capital market integration.

First, member states recognised a shared strategic interest in strengthening cross-border financial markets. Improving the allocation of savings, supporting economic growth, and strengthening financial stability provided a powerful motivation for deeper integration.

Second, progress depended on credible institutions capable of coordinating regulatory cooperation across jurisdictions. Institutions with clearly defined responsibilities, governance structures, and accountability mechanisms were essential to sustain momentum. The European Commission has played a particularly important role in this process. Beyond acting as a rule-maker, the Commission has functioned as the architect of long-term financial integration by translating political ambition into concrete regulatory initiatives. Through programmes such as the CMU, it has aligned financial market reforms with broader economic objectives, including competitiveness, growth, and strategic autonomy.

Third, Europe’s experience demonstrates that integration must proceed incrementally and pragmatically. Differences in legal systems, market depth, and financial structures mean that progress cannot be imposed uniformly. Instead, integration has advanced through mechanisms such as supervisory cooperation, gradual regulatory convergence, and institutional experimentation.

What can ASEAN learn from this experience? 

These lessons are particularly relevant for ASEAN, where diversity among member countries is even greater and supranational authority is absent. Europe’s experience shows that capital market integration depends not only on regulatory reform but also on clear strategic objectives, credible institutions, and sustained supervisory cooperation. While ASEAN’s institutional structure differs from the EU’s, several lessons can guide the region’s next phase of capital market development.

• First, ASEAN will benefit from articulating a clear strategic objective for capital market integration. Regional initiatives will only succeed if anchored in a shared long-term ambition. Policymakers face a choice over whether the goal is gradual free movement of capital and financial services across the region or a more incremental model based on mutual recognition and regulatory interoperability. A sequenced roadmap will help ensure reforms remain coherent and, as importantly, politically sustainable.
  
  
• Second, ASEAN could consider strengthening the role of ACMF as the region’s central coordinating platform. ASEAN is unlikely to replicate the supranational model of the European Commission, but sustained progress requires a credible institution capable of maintaining momentum. Rules — supervisory or regulatory, binding or not — need interpretation, so a body of expert practitioners and lawyers is needed to interpret, arbitrate and help resolve disputes. Over time, the ACMF could evolve beyond coordination to support cross-border supervisory cooperation, enforcement coordination, and oversight of regional digital market infrastructure. Transparent scorecards could help track progress and reinforce accountability.
  
  
• Third, credibility requires institutional permanence. As integration deepens, ASEAN may wish to establish a standing governance structure that is simple, trusted, and operationally effective. Europe’s experience shows credibility can be built without excessive institutional complexity. The ECB’s SSM combines central oversight of systemic institutions with strong national supervision. A similar hybrid model could allow ASEAN to coordinate oversight in areas with clear regional impact while preserving national authority.
  
  
• Fourth, ASEAN could deepen supervisory cooperation by building shared supervisory intelligence. Institutions such as ESMA promote supervisory convergence through peer reviews, joint risk assessments, and data sharing. ASEAN could strengthen similar capabilities through the ACMF, enabling regulators to identify cross-border risks earlier while building supervisory trust.
  
  
• Fifth, integration is likely to benefit from prioritising functional convergence rather than legal harmonisation. The EU’s “single rulebook” demonstrates how common disclosure standards can enable interoperability across diverse markets. For ASEAN, aligning key regulatory areas — including sustainability disclosures, digital asset frameworks, and cross-border investment standards — could strengthen investor confidence without requiring full legal integration. Mutual recognition of sustainable bonds, ESG disclosures, and digital asset frameworks could provide practical early steps.
  
  
• Sixth, ASEAN could prioritise visible “quick wins” that demonstrate the benefits of integration. Europe’s CMU has sometimes slowed where legislative reform dominated. ASEAN could instead focus on practical initiatives such as expanding trading links, developing shared digital platforms for cross-border investment, and strengthening regulatory technology for supervisory monitoring. Initiatives similar to Europe’s European Single Access Point could also reduce information fragmentation across markets.
  
  
• Seventh, ASEAN could adopt a proportional approach to supervision. Europe increasingly applies direct supervision at the regional level for large systemic entities while national regulators oversee domestic firms. A similar hybrid model could allow ASEAN institutions to oversee specific regional market segments — such as pan-ASEAN funds or shared market infrastructure — while national authorities retain responsibility for domestic firms.
  
  
• Eighth, political ambition will need to remain aligned with institutional capacity. Europe’s experience shows integration can stall when objectives outpace governance structures or regulatory resources. Sustained progress will therefore depend on realistic sequencing, adequate institutional support, and continued technical cooperation among regulators.
  
  
• Ninth, respectful diplomacy is likely to be required to find compromises. In Europe, different countries have different ideas about the depth of Supervisory powers to be allocated to ESMA. Smaller and successful ones (Ireland and Luxembourg) fear centralised supervisory interference curbing their competitive supervisory advantage of speed and flexibility. Subsidiarity and proportionality mean different things to different EU member states, and the same will apply to ASEAN. So careful, respectful diplomacy will likely be needed to find compromises.
  
  
• Finally, to support implementation, ASEAN could also consider establishing a Wise Persons Group tasked with developing a practical roadmap for regional capital market integration. Drawing on the expertise of regulators, policymakers, and market participants, such a group could identify achievable institutional models and propose a sequenced reform agenda for ministers to consider. ASEAN might usefully consider also procuring economic studies assessing the costs and benefits of closer cooperation in financial services.
  

Together, these principles point to a pragmatic pathway for ASEAN capital market integration — strengthening cooperation and market connectivity while preserving the flexibility that has long defined ASEAN’s model of regional economic collaboration.

What structural realities must ASEAN consider in its approach? 

Unlike the European Union, ASEAN operates without a supranational legal framework. Progress depends on reinforcing national sovereignty while improving interoperability between markets.  

ASEAN’s diversity presents both opportunities and challenges. The region includes highly developed financial centres as well as emerging and frontier markets. While this diversity complicates regulatory alignment, it also highlights the potential benefits of deeper regional capital market connectivity. 

Existing initiatives demonstrate that progress is possible through pragmatic cooperation. Programmes such as the ASEAN Collective Investment Scheme (CIS) and regional sustainable bond initiatives illustrate how “ASEAN rules, locally enforced” can support cross-border investment while preserving national regulatory authority. 

Flexibility remains a defining feature of ASEAN’s integration model. The ASEAN-X framework, which allows countries to proceed at different speeds, has enabled progress in several areas while avoiding political deadlock. Differentiated integration will therefore continue to play an important role. 

Capacity building will also be critical to narrowing regulatory and market development gaps across the region. Peer-learning networks, regional training programmes, and partnerships with international institutions can help strengthen regulatory capability. 

Finally, alignment with global regulatory standards will remain essential for attracting international capital. Building on frameworks developed by organisations such as IOSCO and the International Financial Reporting Standards Foundation (IFRSF) can strengthen investor confidence and facilitate cross-border investment flows. 

Multilateral institutions such as the Asian Development Bank and the World Bank Group may also play an important role in supporting the development of regional financial infrastructure, including digital market infrastructure and emerging areas such as carbon markets. 

Next steps for ASEAN capital market integration in light of the EU’s experience 

Europe’s experience demonstrates that capital market integration is inherently complex and gradual. Institutional development, regulatory convergence, and market integration evolve over long time horizons and require sustained political commitment.

ASEAN has the advantage of pursuing integration in a relatively stable environment rather than in response to a crisis. This provides an opportunity to design regional financial cooperation deliberately and pragmatically.

However, the process will inevitably be slow and technically demanding. Clear objectives, credible institutional frameworks, and sustained cooperation among regulators will be essential from the outset.

If these foundations are established early, ASEAN has the opportunity to develop a distinctive model of capital market integration — one that reflects its own institutional realities while strengthening regional financial resilience.

By learning from Europe’s experiencs, ASEAN can deepen its capital markets, mobilise regional savings more effectively, and strengthen its role in the evolving global financial system — provided reforms are sequenced realistically and matched to institutional capacity.
