Jio BlackRock will use the distribution reach of its partner and target the existing 8 million active users of financial services on its digital platforms such as MyJio and Jio Finance, a second source familiar with the matter said. BlackRock, the world's largest fund manager at $11.6 trillion as of December 2024, is known for its passive funds, which track established indexes. It manages $7.8 trillion through exchange traded and index funds. However, Jio BlackRock plans to offer a mix of active and passive funds in India, where active funds still dominate. "Passive funds are growing in India every year and there is a potential for BlackRock to further build this segment," said the first source. Passive funds accounted for 12.11 trillion rupees, or 16.78% of total assets in India as of May, marking a 25% growth from a year earlier. The fund house plans to leverage Aladdin, an investment and risk management system, to deliver consistent returns, said the first source.
