Today, legislators, courts, financial regulators and other actors at the EU and national level face major new challenges in safeguarding public and private interests in an increasingly digital and sustainability-minded environment surrounding financial markets. Innovative ways of addressing tensions between the common good and the individual preferences of market actors are needed to address these challenges. However, at present, the efforts to develop workable solutions are seriously hampered by the gap between the two areas of law that profoundly shape the financial markets—financial regulation and private law—in the current European policy discourse and legal scholarship. This article is an attempt to systematically rethink the role of private law in the regulatory and enforcement landscape for financial markets and its relationship with public regulation more generally. It argues that financial regulation and private law are not two parallel universes, but rather two sides of the same coin, each of which has a critical role to play in safeguarding public and private interests. Examining EU financial regulation through the ‘private law’ lens would enable us to unveil a complex interplay between the regulatory dimension, contractual settings and private law remedies that we need to better understand in order to be able to better regulate financial markets. Conversely, examining national private law through the European ‘regulatory’ lens would allow us to unpack the potential of traditional private law to contribute to the objectives of EU financial regulation, while at the same time realising justice between private parties.

如今，欧盟和国家层面的立法者，法院，金融监管机构和其他行为者在围绕金融市场日益数字化和可持续发展的环境中捍卫公共和私人利益方面面临着重大的新挑战。需要创新的方法来解决市场行为者的共同利益与个人偏好之间的矛盾，以应对这些挑战。但是，目前，在当前的欧洲政策讨论和法律学术研究中，深刻影响着金融市场的两个法律领域之间的差距严重阻碍了制定可行解决方案的努力。本文旨在系统地重新思考私法在金融市场的监管和执行环境中的作用，以及它与一般性监管之间的关系。它认为，金融监管和私法不是两个平行的世界，而是同一枚硬币的两个侧面，每个侧面在维护公共和私人利益方面都起着至关重要的作用。通过“私法”的角度研究欧盟的金融法规，将使我们能够揭示监管层面，合同环境和私法补救措施之间的复杂相互作用，而我们需要更好地理解它们，以便能够更好地监管金融市场。反过来，
