arcanum analytica is the culmination of the learnings and observations of rowan calder-ash.

after recognizing that modern economic and capital systems fail to account for the conditions required for long-term societal and planetary homeostasis — ecosystem services, human health, and social stability — rowan shifted toward building tools that internalize these neglected costs, spanning nature-based carbon finance and ecological incentive design. his passion for trading and musing about markets, global economics, the human condition, and the future of planet earth has become arcanum analytica.

rowan's career has included roles in natural capital based real asset investing and portfolio management, environmental and carbon market trading and structuring, commodity derivative book management and trading, as well as discretionary macro and commodity trading lead roles at both private capital managers and large institutions.
