Here is a trillion dollar question: How will the portfolios of long-term asset managers like pension funds, foundations and endowments be affected by climate change? These institutions, in contrast to commercial banks, are legally obligated to take a long-term view in managing their returns. A new report by Mercer, a leading consulting and investment services firm, provides the first look at yet another window on the complex consequences of climate change—the implications for strategic asset allocation.
A headline result of the study is the estimated increase of up to 10 % in overall portfolio risk, primarily due to policy uncertainty—equivalent to as much as US$8 trillion by 2030. Traditional equity and bond holdings—usually the most conservative forms of hedging against uncertainty –- are most at risk of underperformance. In contrast, carefully selected investments in climate- sensitive sectors may actually reduce overall portfolio risk.
The International Finance Corporation (IFC) and UK’s Carbon Trust, along with 14 institutional investors collectively managing over US$2 trillion, funded the analysis, which was carried out by Mercer. The analysis looks at impacts by sector, region, and asset category (bonds, private equity, real estate, etc.) and builds on a set of climate change scenarios out to 2030 developed by the Grantham Research Institute at the London School of Economics and the consulting firm Vivid Economics.
