New Stablecoin OUSD Challenges Incumbents: Will Reserve Earnings Drive Capital Shifts?

Executive summary

Open Standard has announced the launch of Open USD (OUSD), a new US dollar-pegged stablecoin, with a stated aim to challenge the market dominance of Tether's USDT and Circle's USDC. According to a Tuesday notice from Open Standard, the project is supported by a consortium of over 140 companies, including major financial entities like Visa and Mastercard, alongside prominent crypto firms such as Coinbase, Ripple, OKX, and Bybit. A key differentiating feature of OUSD, as communicated by Open Standard, is that it will allow businesses to mint the stablecoin at no cost, with no artificial volume limits, and crucially, to retain all earnings generated from its underlying reserves. This model directly contrasts with existing major stablecoins, which typically retain these reserve earnings.

The announcement appears to have had an immediate market reaction, with Circle Internet Group's share price reportedly dropping by more than 16% on Tuesday, closing at $63.63. The stablecoin market currently exceeds $312 billion in market capitalization, according to DefiLlama, and is projected to reach up to $4 trillion by 2030. The launch of OUSD is set to occur "later this year," according to Open Standard. This development also aligns with a more favorable regulatory environment in the United States, following the signing of the GENIUS Act last year, which established a framework for payment stablecoins. This legislation is expected by many experts to facilitate the growth and adoption of digital assets by companies.

Why it matters

The introduction of Open USD (OUSD) represents a significant development in the stablecoin market, primarily due to its innovative economic model and the high-profile institutional backing. The core differentiator — allowing participants to receive all earnings from OUSD's reserves — creates a direct economic incentive for adoption that could significantly impact capital flows within the stablecoin ecosystem. This is a real economic impact, not merely a branding exercise, as it directly challenges the revenue models of incumbent stablecoins like USDT and USDC, which typically retain these earnings. Businesses and institutions, particularly those with large stablecoin holdings, may find this model attractive, potentially leading to a gradual shift of capital.

The involvement of major payment networks such as Visa and Mastercard, alongside leading crypto exchanges and platforms, signals a strong institutional push for OUSD. This broad consortium could facilitate widespread integration and adoption across both traditional finance and decentralized finance (DeFi) ecosystems. Increased institutional participation could expand the overall stablecoin market beyond its current size, potentially increasing the total market capitalization (currently $2.12T for the total crypto market, with BTC dominance at 55.4%). Greater stablecoin liquidity and easier on/off ramps for fiat could indirectly benefit broader crypto assets like Bitcoin (BTC) and Ethereum (ETH) by improving market depth and accessibility. Historically, increased stablecoin supply has often correlated with broader crypto market liquidity.

However, OUSD faces substantial hurdles. Tether's USDT and Circle's USDC possess deep liquidity, extensive integrations across exchanges and DeFi protocols, and strong network effects built over years. Dislodging these incumbents will require OUSD to demonstrate consistent peg stability, robust liquidity, and seamless integration across a vast array of platforms. While the regulatory clarity provided by the GENIUS Act offers a supportive backdrop, the actual implementation and market acceptance of OUSD will be critical. The market reaction to Circle's share price suggests a perceived threat, but actual capital reallocation will depend on OUSD's successful launch and sustained operational performance. Fragmentation of the stablecoin market, if OUSD only captures a small, isolated segment, could also dilute overall liquidity rather than enhance it.
