- Abstract
- This box investigates the measurement of banks’ exposures to concentration risk related to climate change. It does so by introducing a new metric to quantify carbon-related concentration risk in banks’ corporate loan portfolios. Using data on individual borrowers’ emissions, the formula of the Herfindahl-Hirschman Index (HHI) is extended to create a carbon-weighted HHI (cwHHI). The cwHHI reveals substantial heterogeneity in the degree of carbon-related concentration among portfolios similarly exposed to high-emitting firms. Furthermore, banks with exposures to high-emitting firms similar to their peers but with higher cwHHI experience higher expected losses in a disorderly transition scenario. The empirical findings of this box suggest that institutions and exposures significantly affected by carbon-related concentration risk run a higher risk of incurring losses, extending even to those banks with a lower share of exposures to high emitters. The implication is that carbon-related concentration risk may be a material risk driver.
