Ethical investors tightening screws on emerging-market debt issuers – by Claire Milhench (Reuters U.S. – December 18, 2017)

LONDON (Reuters) – For years, the Brazilian mining conglomerate Vale was a darling of emerging market investors, who were happy to ignore the company’s poor record on environmental and social issues because of the high yields its bonds paid.

But warnings about the company’s policies were horribly vindicated in 2015, when a dam holding back waste at its Samarco mine burst, killing 19 people in Brazil’s worst-ever environmental disaster.

Prices on Vale and Samarco bonds plummeted by about a third after the disaster. Vale, along with mine co-owner BHP Billiton, is facing a multi-billion dollar claim.

Events like that are increasingly spurring fund managers to look closer at environmental, social and governance (ESG) risks before investing in emerging markets, where polluting industries and accounting issues have often gone unpunished.
