Open USD Stablecoin Threatens Circle's USDC Margins: CoinShares

The consortium stablecoin's reserve-yield sharing model strikes at the core of Circle's economics, and arrives weeks before Coinbase's revenue-sharing renewal could reset the terms.

Open USD Stablecoin Threatens Circle's USDC Margins: CoinShares

Open USD, the bank-backed consortium stablecoin under development by Open Standard, poses the most credible threat yet to Circle Internet's USDC because it attacks the economics at the heart of the issuer's business, crypto asset manager CoinShares said in a Monday report. Unlike conventional stablecoin issuers that keep the income generated by their reserves, Open USD plans to distribute reserve yield to participating businesses and retain only a management fee, a model CoinShares says could squeeze Circle's margins while raising the cost of maintaining USDC distribution across partners.

Backed by more than 140 companies including BlackRock, Coinbase, Mastercard, Stripe and Visa, Open USD is targeting a second-half 2026 launch. The model also strengthens Coinbase's leverage ahead of the August 18 renewal of its revenue-sharing agreement with Circle, under which the exchange receives roughly half of USDC's reserve income.

Why it matters

The report lands at a sensitive moment for Circle. USDC's circulating supply has slipped to about $73 billion from nearly $80 billion in March, trimming its share of the roughly $312 billion stablecoin market as regulated competitors press in. Circle shares fell more than 17% on the day Open USD was announced, though CoinShares attributes part of that move to technical selling tied to a Russell index reconstitution.

The structural risk is the yield-share model itself. If partners capture the reserve income Circle now keeps, the incentive to route flows through USDC weakens at exactly the moment Circle's distribution agreements are coming up for renewal. CoinShares analyst Luke Nolan wrote that, if successful, Open USD could pull stablecoins further into mainstream payments by making the economics more attractive to the businesses actually using them.

Market impact

Mizuho moved in the same direction on Tuesday, downgrading Circle to underperform from neutral and cutting its price target to $50 from $85, arguing the rival's model threatens long-term economics. Circle shares were 3.8% higher in early trading at $65.61.

Still, CoinShares flags reasons not to overreach the bearish read.

  5. Could Open USD also threaten Tether's USDT?
