"Interfund lending exemptive relief is commonly granted by the SEC to mutual fund complexes," BlackRock spokeswoman Tara McDonnell said.
Cash for the loans would come from other BlackRock funds, which will likely earn more in interest lending to peers than they would investing in short-term debt like repurchase agreements, BlackRock told regulators.
That rate would also be lower than what banks would charge funds to borrow for the same purpose.
BlackRock, which manages nearly $5 trillion in assets, has already arranged for its funds to be able to tap outside credit lines during times of stress.
