Global asset management giant BlackRock has announced that it has officially appointed Citigroup to provide specific middle-office service support for its US-registered iShares exchange-traded funds (ETFs), with related assets totaling as much as $4.0 trillion.

This service will be deployed through BlackRock's independently developed Aladdin investment management platform, marking a new stage in the cooperation between the two parties in the field of financial technology services. As the world's largest asset management company, BlackRock has chosen Citi as its service partner this time, aiming to optimize the operational efficiency of its extensive ETF product line. The Aladdin platform will serve as the core technology carrier, integrating Citi's middle-office service capabilities to provide more precise operational support for the iShares ETF product line. This cooperation model is expected to set a new benchmark for the technological transformation of the asset management industry.
