The iShares € Corp Bond ex-Financials Ucits ETF will switch in May, subject to shareholder approval

BlackRock plans to switch a €1.4bn iShares corporate bond exchange traded fund to an environmental, social and governance index in response to investor demand.

The world’s largest asset manager has asked shareholders of its Dublin-domiciled iShares € Corp Bond ex-Financials Ucits ETF to approve an index change to the Bloomberg MSCI Euro Corporate ex Financials Sustainable SRI at an extraordinary general meeting on March 25.

BlackRock, which has about $10tn in assets under management, said no changes would be made to the total expense ratio of the ETF, which stands at 0.2 per cent.

The US mutual fund giant has changed indices on several iShares products. Rival asset managers such as DWS and BNP Paribas Asset Management have also switched benchmarks on some of their ETFs.
