While IEUS is just one ETF, its index swap is the latest win for MSCI in the ultra-competitive indexing business. In July, the company said $84 billion flowed into U.S.-listed ETFs with $29 billion, or 34%, heading into ETFs that benchmark to MSCI indices.

New ETFs backed by MSCI indices are also proving to be impressive asset gatherers. In the first half of 2014, “75 ETFs based on MSCI indexes – around one third of all equity ETFs launched, raising a total of approximately USD 1.5 billion,” according to MSCI.

With over 650 ETFs tracking MSCI indexes globally, more ETFs track MSCI’s indexes than those of any other index provider, said MSCI in the statement.

Four Global X ETFs – the Global X MSCI Colombia ETF (NYSEArca: GXG), Global X MSCI Norway ETF (NYSEArca: NORW), Global X MSCI Argentina ETF (NYSEArca: ARGT) and the Global X MSCI Nigeria ETF (NYSEArca: NGE) – have swapped to MSCI indices this year.
