The Fiscal Consequences of Cascading Climate, Nature and Macro-Financial Risks

Alexander is a DPhil candidate at the Environmental Change Institute (ECI), University of Oxford, supervised by Dr Nicola Ranger and a member of the Global Finance and Economy Group at the ECI and the Leverhulme Center for Nature Recovery. His research focuses on the interplay between climate change, environmental degradation, and the macroeconomy. Specifically, it aims to develop scenario analysis capturing the feedback between cascading climate- and nature-related financial risks with macro-financial fragilities, and quantify the implications for sovereign debt sustainability and creditworthiness.

Alongside his doctoral studies, Alexander is a fixed-term Research Economist with S&P Global Ratings working on nature- and climate-integrated macro-financial forecasts, and a Research Assistant at the ECI for projects related to Sovereign Nature Finance and Earth Observation. Previously, he was a Senior Fixed Income Analyst at the UN Principles for Responsible Investment, and a researcher at the Grantham Research Institute on Climate Change and the Environment at the London School of Economics (LSE), where he co-authored a policy report on 'aligning sovereign bond markets with the net zero transition: the role of central banks'. He began his career in the financial industry as a Climate Finance Research Fellow at Barings Investment Management, Sovereign Debt and Currencies.

Alexander holds a double MSc (Distinction), in International Political Economy from the LSE and in International Economic Policy from Sciences Po, major in quantitative methods, and a BSc. (Distinction) in International Business and Politics from Copenhagen Business School (CBS). He volunteers as Social Secretary for his college at Oxford and tutor/mentor, previously co-founded CBS Climate Club, and was a student research assistant at the Copenhagen School of Energy Infrastructure. He is supported by the German Federal Ministry for Research and Education via the Friedrich-Naumann-Foundation.
