Abstract
High-profile failures in financial trading have led to interest in how the culture of the industry produces risky and unethical behaviours among traders. Yet, there is no established theoretical framework for studying this: we apply safety culture theory to examine ten recent high-profile trading mishaps investigated by the UK financial regulator. The results show that the dimensions of safety culture used to understand organisational accidents in domains such as aviation also explain failures in Risk Management within financial trading organisations. This counters narratives focusing on traders who are unethical ‘rule breakers’, and emphasises the value of a systemic approach, whereby safety culture theory is used to explain why risky behaviours in financial trading occur. Safety culture therefore provides a conceptual basis for further research on risky and unethical behaviours in financial trading, alongside providing insights for possible intervention.
