The Hazelhoff Financial Law Series intends to deepen and further the debate on topical financial law issues. It represents the key results of the work of the Hazelhoff Centre for Financial Law at Leiden Law School. We understand financial law to encompass, inter alia, the legal aspects of financial supervision, the organization, functioning and regulation of financial markets, securities and finance transactions, market abuse, payments and payment systems, duties of care in the banking sector and bank insolvency.
