Throughout the world the nature and regulation of financial systems have changed dramatically following the global financial crisis. This book introduces the necessary theory and a range of relevant statistics to supplement the narrative. Coverage includes a critique of the UK financial institutions and markets, as well as regulation emanating both from within the UK and also from supranational bodies such as the Bank for International Settlements and the European Union. The discussion is based on both the underlying theory as well as the operating practices of the institutions and markets. The book is subdivided into three main sections, each supplemented by a comprehensive glossary: financial institutions; financial markets; and the regulation of banks and other financial institutions. It will be essential reading for undergraduate students enrolled on courses in financial economics and banking.
