RLUSD eyes a slice of $13T treasury cash

Ripple's stablecoin lead Jack McDonald says RLUSD is chasing a $13 trillion pool of corporate treasury cash, not the everyday payments volume stablecoins usually get pitched on. That number is the total cash and short-term investments US public companies hold, and RLUSD's current supply is a rounding error against it.

The size of the target

McDonald's framing puts RLUSD in competition with money market funds and bank deposits, not with Tether or USDC's consumer flows. The pitch: idle corporate cash sitting in low-yield accounts could instead sit in a stablecoin instrument tied to Ripple's payments rails.

• RLUSD's circulating supply sits near $700 million, per CoinDesk.
• The $13 trillion figure represents aggregate US corporate cash and short-term investment holdings cited by Ripple's stablecoin chief.
• Tether's market cap runs near $172 billion and Circle's USDC near $73 billion, the two incumbents RLUSD trails by orders of magnitude.
• Visa's stablecoin settlement volume already runs at a $20 billion annualized rate, showing where enterprise stablecoin usage is actually concentrating today.

What the framing skips

Most coverage will take the $13 trillion figure as a market-sizing exercise and move on. The real argument here is about who Ripple thinks it's competing with.

Money market funds pay yield through regulated structures with decades of institutional trust and same-day liquidity built into treasury workflows. RLUSD offers none of that yield directly under most current stablecoin rules, and the GENIUS Act framework in the US bars issuers from paying interest on the token itself.

That gap matters. A corporate treasurer holding cash in a money fund earns yield without giving up liquidity or taking on issuer risk tied to a single company's balance sheet.

Ripple's actual bet looks narrower than the headline number suggests: cross-border settlement speed and on-chain programmability for specific corporate use cases, not a wholesale replacement of treasury management. RLUSD's $700 million supply against $13 trillion in addressable cash is a 0.005% share, and even capturing a sliver of that would dwarf RLUSD's current size many times over.

The company's own comparison points are Tether and USDC, both of which built their scale on crypto trading and payments rails, not treasury substitution. RLUSD reaching a fraction of that scale by targeting corporate cash would require solving a yield and liquidity problem that stablecoin issuers as a category haven't cracked yet.

The GENIUS Act constraint

The regulatory backdrop shapes what RLUSD can actually offer. Issuers can't pay interest directly, so any treasury pitch has to come through side deals, tokenized money-fund wrappers, or Ripple's own custody and settlement fees rather than a yield-bearing stablecoin itself.

That's a structurally different sell than "hold RLUSD and earn yield." It's closer to "hold RLUSD because our rails move it faster," a value proposition that depends on adoption of Ripple's broader payments network, not the token's economics alone.

What would confirm the read

The gap between a $13 trillion addressable market and a $700 million token supply is the story until real treasury deployments show up.

• Watch for named corporate treasury clients disclosing RLUSD holdings above nine figures, not pilot announcements.
• Watch whether Ripple or partners launch a yield-bearing wrapper around RLUSD that stays compliant with GENIUS Act interest restrictions.
• Watch RLUSD's supply growth rate over the next two quarters against Tether and USDC's own growth, to see if the gap closes or widens.
