On July 21th 2010 was signed into law by President Obama United State’s most important legislative change to financial supervision since the 1930’s : the Dodd-Frank Wall Street Reform and Consumer Protection Act. This paper suggests that the Dodd-Frank Act, notwithstanding certain flaws, reflects what the neo-realistic definition of Regulation has been proposing in regards to post-crisis reregulation. Inter alia, it takes into account markets interconnectedness, complexity and deregulation. As regulatory law suggests to do, the Act reconciles microeconomic and macroeconomic supervision as well as regulatory and prudential rules, and resorts to certain regulatory tools in order to achieve certain regulatory goals. More specifically, it revives four regulatory imperatives: oversight and systemic risk prevention, investor protection, transparency/information and prudential measures.
