Finance regulation

Financial markets and financial institutions are subject to extensive and complex regulation, and these regulations change frequently. Thommessen offers market-leading legal advice to all actors in the financial sector. We have advised on the largest and most complex projects in the financial services sector and provide ongoing advice and assistance on all issues related to financial markets and financial services.

Financial institutions have an important role in society. Well-functioning financial markets is a prerequisite for economic growth and financial stability. The financial sector also serves as an important tool for addressing other challenges in society, including adapting to climate change and the fighting against money laundering. At the same time, financial institutions introduce risks, both for the society as a whole and for individual investors. The financial sector is therefore subject to extensive and complex regulation, both in the EU and in Norway.

Our lawyers have broad experience in providing ongoing hands-on advice to all types of companies in the financial industry and work frequently on larger transactions. Several of our lawyers have long experience from key government agencies such as the Financial Supervisory Authority of Norway, the Ministry of Finance and the Banking Law Commission. We distinguish ourselves from our competitors through in-depth knowledge of both Norwegian and European regulatory processes and practical know-how in how regulatory authorities act in various situations.

Over a number of years, Thommessen has assisted in the largest and most complicated authorization processes and is a sought after advisor on all types of transactions in the financial sector. We also advice on strategic matters and provide clear, practical advice in managing change-processes as well as on-site supervisory inspections.
