Open USD & the Repricing of Stablecoin Economics

• OUSD plans no minting fees or volume caps and would distribute reserve income to partners net of management fees, making what Circle pays Coinbase ($907.9M in 2024, roughly 54% of Circle's revenue) the sector default instead of a negotiated cost.
• Total stablecoin supply was $292.3B as of August 2, 2026, down 4.6% from May peak, with USDC contracting 7.6% over 90 days to $71.5B despite on-chain transaction volume growing 263% year-over-year in Q1.
• OUSD is not yet live (targeted H2 2026 on Ethereum, Solana, and Tempo), some named partners have disputed participation, and regulatory constraints under GENIUS Act and proposed CLARITY bill bar direct yield to holders, shifting competition to distribution economics.

Summary: Open USD & the Repricing of Stablecoin Economics

Key Announcement

On June 30, 2026, over 140 firms including Visa, Mastercard, Stripe, BlackRock, Google, BNY, and Coinbase announced Open USD (OUSD), a new dollar stablecoin governed by Open Standard. Circle shares fell 17.5% to $62.63 that day, though concurrent removal from five Russell growth indexes contributed to selling pressure.

Business Model Disruption

OUSD represents a fundamental shift in stablecoin economics. Unlike incumbents Circle and Tether that retain reserve income, OUSD would pass this income to distribution partners (minus management fees), eliminating minting fees and volume caps. This model transforms what Circle negotiates as costs into industry-wide defaults.

Financial Impact

Reserve income comprised 94% of Circle's Q1 2026 total revenue. Circle paid Coinbase $907.9M in 2024—roughly 54% of annual revenue—under an agreement expiring this month. Coinbase now sits on both sides as both Circle partner and OUSD consortium member.

Market Context

Total stablecoin supply reached $292.3B on August 2, up 13.7% year-over-year but down 4.6% from May's $307.7B peak. USDC contracted 7.6% over 90 days to $71.5B, while USDT declined 3.3% to $183.0B. Despite USDC transaction volume surging 263% year-over-year in Q1, revenue fell to $694.1M from $770.0M.

Regulatory Landscape

The GENIUS Act bars issuers from paying yield to holders. The CLARITY bill (pending legislation) would permit activity-based rewards while prohibiting yield on idle balances, forcing competition toward distribution economics.

Investment Implications

OUSD launches natively on Ethereum, Solana, and Tempo in H2 2026, though reserve composition and custodian remain unconfirmed. Some named partners dispute participation. For digital-asset infrastructure investors, reserve margins—not usage—represent the critical vulnerability. Circle
