The Twin Peaks Model is favored for several reasons, primarily due to its structural advantages. Each of the two regulatory bodies within the model has clear and separate objectives, allowing them to focus effectively on their specific mandates (Wymeersch, 2007). This model also minimizes regulatory risks, particularly in terms of prudential regulation, which is a central feature. Furthermore, the concept of regulatory culture plays a significant role, encompassing the policies, attitudes, and actions that regulators employ to fulfill their roles, thereby preventing potential conflicts arising from diverse regulatory approaches.
Another strength of the Twin Peaks Model is its adaptability to the complexities of modern financial conglomerates and markets, as seen in how the Netherlands tailored the model to meet its unique requirements. Additionally, it helps resolve conflicts that may occur in a single regulatory framework, as noted by Godwin et al. (2017).
Moreover, lessons from the recent financial crisis highlight the drawbacks of merging regulatory functions, which can lead to a diminished focus on macro-prudential risks and create challenges in responding effectively when those risks escalate. The conflicting incentives are also notable; for example, keeping a bank operational might serve consumer protection but could compromise overall financial stability (JCFSB, 2010).
