According to PANews, Circle has entered into a new memorandum of understanding with BlackRock, signed in March 2025, designating BlackRock as the preferred partner for managing Circle's stablecoin reserves. The agreement stipulates that BlackRock will oversee at least 90% of Circle's dollar custody reserves, excluding bank deposits, while committing not to issue a competing dollar payment stablecoin. This partnership is set to last for four years, reinforcing Circle's strategic approach to stablecoin management.
