The call for establishing a right to bank holds valid premises, yet this right has never been contemplated before. The book argues that introducing a right to bank under international law can offer a new route to ensure that the banking sector acts as a force for good like ethical banks currently do. The right to bank aims to address the fundamental issues that customers can experience while dealing with banks, introducing the paradigm: get access; be respected; trust the system . The right to bank is a right for everyone: in the transition from a financial crisis to a climate crisis, it empowers individuals to play an active role in the financial system through ethical and sustainable decision-making. It also stimulates financial institutions and governments to reflect about the fundamental role they play and to act wisely in furthering the ecological transition. The book therefore presents a proposal for establishing a right to bank, explaining the issues that this right aims to address, the benefits linked to its adoption, and the intended change it can trigger. This innovative work will be valuable for lawmakers, banking and finance professionals and researchers, governments and NGOs, including UN bodies.
