New Time-Dependent Risk-Return Tradeoffs from CBI Certified Municipal Bonds

Forced to address human-induced climate change, the world has embarked on the transition to a low-carbon economy, requiring massive amounts of financing. Municipalities in the US have begun to issue bonds that are third-party certified and registered with the Climate Bonds Initiative (CBI) to attract funding for much-needed climate-related infrastructure. As this market is developing, borrowers and lenders are assessing the potential for new risk-return tradeoffs over time. Variations in the pricing of CBI certified municipal bonds with different terms to maturity likely depend on the extent to which climate-related projects are expected to be prioritized in fund allocations to correspond to increases in public attention to the dynamics of climate change.
