A study on the evolution and impact of regulatory frameworks in investment banking

Abstract

Widespread reform initiatives aimed at improving the stability of the financial system were prompted by the 2008 global financial crisis, which revealed serious weaknesses in the regulatory framework controlling investment banking. This study analyzes the development of post-crisis regulatory actions and evaluates their effects on the investment banking sector. Key reforms such as the Dodd-Frank Wall Street Reform and Consumer Protection Act, the Volcker Rule, and Basel III established higher capital requirements, risk management standards, and limitations on proprietary trading. This research explores how these regulations have reshaped the operations and risk-taking behavior of investment banks, while also addressing their unintended consequences, including reduced market liquidity and changes to profitability models. Through a review of case studies and industry data, the paper evaluates the effectiveness of these reforms in reducing systemic risk and fostering financial stability. Additionally, it considers ongoing challenges such as regulatory complexity, market innovation, and emerging risks from technological advancements. The findings suggest that while post-2008 regulations have significantly improved oversight, continuous adaptation of the regulatory framework is essential to address evolving risks in the global financial landscape.
