Financial institutions and multinationals manage enormous cash flows. This means they play a central role not only in the global economy, but also in major political and social developments, such as the energy transition, international sanctions and geopolitical conflicts. Sometimes their influence is downright problematic. Banks can, consciously, facilitate cash flows to authoritarian regimes or companies that contribute to pollution. In such cases, the ethical boundary is clear. But there are also situations in which responsibility is less clear-cut. Can you hold a financial institution morally responsible for something it is not aware of?
