This article explores long-term trends in risks and returns within central banking using Danmarks Nationalbank as a case study. Core earnings generated by the basic functions and the associated risks typical of a central bank accounted on average for most of the Nationalbank's financial returns over the past 175 years. For a long period, this was the result of a passive risk-management strategy under which financial risks and returns just reflected the various functions performed by the Nationalbank and not the outcome of a deliberate decision-making process. A formalised and holistic risk-management framework was introduced only in the 1990s.
