In recent years, an increasing number of clients and third parties have filed claims against banks such as for mis-selling financial products, poor financial advice, insufficient disclosure of and warning about financial risks. The scope of a banks duty of care seems to expand, not only to include protection of consumers against unclear risks of complicated products but also protection of professional parties against more obvious risks of relatively straightforward products. This topic raises many questions, both at a theoretical and practical level. This book provides a rich source of information about how various jurisdictions (Germany, Austria, France, Italy, Spain, the Netherlands, England and Wales, Ireland, and the United States of America) deal with these questions and how answers are found or embedded in their national legal systems. The book also contains a detailed chapter on the MiFID I and II conduct-of-business provisions. Finally, the book provides a thorough comparative analysis and perspective.
