As a result of the Global Financial Crisis in 2007, the financial and bank supervision in many countries was reformed. Stanyo Dinov investigates the Central Banks of the three advanced financial systems – the UK, the USA and the EU – and the questions related to their supervisory role. All three banks historically and symbolically represent different legal systems, influenced by each other and comparable to one another. They all represent the model of free market economy, whose roots began with the idea of economic liberalism and wellbeing from Adam Smith. The legislators in the UK, the USA and the EU have chosen solutions that are in some ways similar though in other ways different to reform these financial systems. Therefore, on the basis of their historical development, the author presents and compares the post-crisis reforms by these three systems, with the main focus on the CBs’ role as banking supervisor. Existing problems are discussed and some alternative solutions are presented.
