Amundi is set to change the underlying indices on six fixed income ETFs to ESG as demand for sustainable products in the bond space continues to soar. All six core fixed income ETFs will track ESG versions of the same iBoxx index except the €706m CC4 which has switched from the Markit iBoxx Euro Liquid Corporates Top 75 Mid Price TCA index to the Bloomberg Barclays MSCI Euro Corporate ESG Sustainability SRI index.
