Retail deposit and lending markets are central to economic growth, productivity and financial stability. Prudential regulation underpins the stability and trust on which deposits, credit and investment depend, while competition drives efficiency, innovation and higher-quality financial services. Yet, the interaction between prudential regulation and competition policy can be both complex and dynamic.
Prudential safeguards influence the conditions for competition by determining who may enter, operate and exit the market, thereby shaping the structure of core banking markets. Insufficient oversight or an overly narrow prudential perimeter can allow vulnerabilities to accumulate and amplify systemic risk, while poorly calibrated safeguards may unintentionally or unnecessarily discourage competition. Because competition can promote more dynamic and resilient deposit and lending markets, rewarding higher-quality institutions and encouraging innovation, calibrating prudential regulations with awareness of their effects on competition can help sustain both stability and efficiency.
Prudential regulations that are proportionate and risk-based can safeguard resilience while maintaining conditions for contestability. Competition policy and enforcement can, in turn, complement prudential goals by preventing the negative effects of excessive concentration and anticompetitive conduct. In practice, the alignment of these objectives may depend on how prudential measures are calibrated, how competition considerations are integrated into their design and how authorities co-operate in monitoring market developments. Key policy considerations in this context include:
International co-operation and coherent frameworks can help align objectives. Consistent approaches to prudential and competition policies can sustain a level playing field and stability as markets evolve and integrate.
Co-operation between prudential and competition authorities supports balanced outcomes. Regular dialogue and joint initiatives, such as sandboxes, market monitoring and forward-looking assessments, can provide opportunities to identify emerging risk, trade-offs, or complementarities.
Systematic competition assessments of new and existing prudential frameworks can help identify and address rules that inadvertently restrict competition while safeguarding prudential goals.
Proportionate, risk-based regulation can preserve both resilience and contestability. Tailoring prudential requirements to risk profiles or complexity may help prevent undue barriers to entry or expansion while ensuring effective prudential oversight.
Competitive neutrality can be a helpful guiding principle in balancing objectives. When crafting prudential rules or measures in the face of trade-offs, the least distortive solutions should be sought in seeking a balance.
Credible mechanisms for market exit can contribute to both competition and stability. Effective resolution tools can enable inefficient institutions to exit the market without contagion or reliance on mergers or state support, while avoiding potential long-term anticompetitive distortions.
The interaction between prudential regulation and competition shapes both the resilience and the openness of banking markets. These policies can be most effective when treated as complementary, where possible, or when trade-offs are properly calibrated in light of the other’s objectives. Sustained dialogue, proportionate rules and coherent frameworks, domestically and internationally, can help ensure that measures designed to safeguard stability also preserve competition and innovation over time.
