BlackRock Strengthens ETF Operating Platform by Diversifying Post-Trade Service Providers

BlackRock |Feb 01, 2024

London – 1 February 2024 – BlackRock today announced that BNY Mellon will join State Street as depositary and administration service providers for iShares’ USD729bn / EUR 673bn1 AUM Irish-domiciled exchange traded funds (ETFs).

This follows BlackRock’s announcement in 2021, of the diversification of post-trade custodians for U.S. domiciled ETFs, which included BNY Mellon with a share of 15% of the contemporary AUM2 of U.S.-listed iShares ETFs.

Mitigating risk and creating efficiency

BNY Mellon3 will provide depositary (including custody), fund administration and fund accounting services to a selection of Irish-domiciled iShares ETFs. State Street will continue to be the registrar and transfer agent for all Irish-domiciled iShares ETFs.

The end state of this project, after the transitions of assets in the coming months, will lead to broadly a 50-50 asset split for depositary and administration between State Street and BNY Mellon based on today’s valuation (BNY Mellon share USD356bn / EUR329bn4). This will only impact BlackRock’s iShares Irish-domiciled ETFs. Fund administration and depositary for the rest of BlackRock’s European iShares ETF ranges (including the iShares ETF ranges domiciled in Switzerland and Germany) will remain with State Street.


Details of the BlackRock December 2021 US Custody Announcement

In December 2021, BlackRock announced that BNY Mellon, Citi and JP Morgan would join State Street as post-trade service providers for iShares’ U.S. domiciled ETFs. Each firm provides custodial, fund administration, fund accounting, and transfer agency services to a subset of U.S. listed iShares ETFs.
