Woofun AI notes that Mizuho maintains a "neutral" rating on Circle despite the company securing final approval from the Office of the Comptroller of the Currency to establish the First National Digital Currency Bank. The investment bank argues that this regulatory milestone does not resolve core challenges, highlighting that USDC circulating market capitalization has dropped approximately $7 billion to $74 billion since March, potentially impacting transaction revenue and reserve income.

Furthermore, Mizuho points to intensifying competition from Open USD, a GENIUS Act-compliant stablecoin backed by over 140 firms including Mastercard, Stripe, and Coinbase, which may lead to industry homogenization and reduce Circle's competitive advantage.
