Article | Expect the worse, hope for the best: the valuation of climate risks and opportunities of sovereign bonds

The CCPI data were used to assess

  • The climate transition risk of a sovereign (national climate policy sub-score)
  • The overall transition performance of a sovereign (Aggregated CCPI score)

Summary:

  • Analysis of pricing-in of climate risk exposure and climate performance in sovereign bond yields, differentiated by physical risks, transition risks, and innovation opportunities.      
  • The results show that financial markets started to take climate performance and climate risk exposure into account, yet to varying degrees.
  • Effects differ considerably between countries with higher and lower credit rating, bonds with long- and short term maturities, and the period of analysis.
  • Physical risks are shown to be primarily priced-in for countries with lower credit rating, and their bonds at longer-term maturities.
  • Transition risks and climate innovation opportunities are of importance to higher-rated sovereigns for bonds with shorter-term maturities.
  • These effects are stronger for the period after the Paris Agreement.
  • Implications for policy and practice:
    • Countries with lower credit rating could reduce their bond yields with climate change adaptation strategies to mitigate climate change physical exposure risks.
    • Countries with higher credit rating could reduce their bond yields with a stronger climate policy performance and more climate innovation opportunities.
    • Investors and financial market actors should take climate risk exposure and climate performance indicators into account to assess the financial health of a country.

The CCPI data is requested and used for research and science purposes. The CCPI was used as a source in this paper by Julia Bingler:
