Circle won OCC approval for Circle National Trust under federal oversight, but Mizuho said the move does not offset weaker USDC circulation and rising competition from compliant stablecoins.
Mizuho maintained its neutral rating on Circle after the U.S. Office of the Comptroller of the Currency approved the company to establish Circle National Trust, a federally regulated trust bank. The bank said the approval is positive and gives Circle direct federal oversight, but does not change its core concerns about USDC's momentum and competitive pressure. Mizuho said USDC's circulating supply has fallen by about $7 billion since its March peak to roughly $7.4 billion, the largest monthly contraction since 2022, while competition is intensifying as more than 140 companies, including Visa, Stripe and Coinbase, back Open USD under the GENIUS Act. Circle shares rose 5% on Friday before falling 4.7% to $63.03 on Monday, giving back most of the earlier gain.
