A stablecoin makes one promise above all others: that it can be redeemed at par, on demand. Everything else — the technology, the distribution, the branding — is secondary to whether that single promise holds when it is tested. And that promise can only be kept if the assets behind the token can actually be turned into dollars at the moment holders ask for them. This is why RUSD's reserve is built liquidity-first, and why it is limited to cash and short-term US Treasuries.
Liquidity is the whole point
The reserve exists to meet redemptions. Its job is not to generate the highest possible return, nor to showcase a diverse portfolio of assets — its job is to be there, in full, when someone wants their dollar back. That reframes the question of what belongs in a reserve. The right test is not "what yields the most?" but "what can we convert to cash quickly, at a predictable value, under any market condition?"
By that test, cash and short-term US Treasuries are close to ideal. Treasury bills are among the most liquid instruments in the world, with deep secondary markets that function even during periods of stress. Their value is stable and predictable, they carry minimal credit risk, and tokenised versions can now be redeemed around the clock. RUSD's reserve is structured so that at least 70% sits in this liquidity buffer — cash held at insured institutions plus tokenised US Treasuries — with the remainder confined to liquid, short-duration instruments that can also be realised quickly.
What we refuse to hold
Just as important as what backs RUSD is what does not. We deliberately exclude real estate, locked or illiquid private credit, and any token issued by us or our affiliates from the reserve. These exclusions are not arbitrary — each represents a failure mode that has broken stablecoins before.
Real estate is the clearest example. It may be valuable, but it cannot be sold in hours, and its price is opaque and slow to adjust. A stablecoin that backs on-demand redemption with property is promising something it structurally cannot deliver: instant liquidity from an illiquid asset. Locked private credit carries the same mismatch, with the added risk of borrower default. And self-issued tokens introduce reflexivity — if confidence falls, the token used as collateral falls too, accelerating the very collapse it was meant to prevent.
The lesson from past failures
The history of stablecoins is, in large part, a history of asset-liability mismatch. Projects backed by illiquid or correlated assets have repeatedly held up in calm conditions and then failed the moment redemptions accelerated. When holders rushed for the exit, the assets could not be sold fast enough or at the assumed value, the liquid portion was drained first, and the peg broke — often within hours. The pattern is consistent enough to be treated as a rule rather than a coincidence.
RUSD is designed around that rule. By holding only assets that can be converted to dollars quickly and at predictable value, the reserve is built to meet redemptions precisely when meeting them is hardest. We would rather accept a simpler, lower-yielding reserve than take on the kind of asset that looks impressive on a balance sheet but disappears exactly when it is needed.
A deliberate trade-off
Holding cash and Treasuries means RUSD's reserve is, by design, unexciting. It will never feature a portfolio of trophy assets. That is the point. A payment stablecoin's reserve should be boring, liquid, and verifiable — because the people who hold it are not looking for exposure to interesting assets. They are looking for a dollar that is there when they need it. That is the standard RUSD is built to meet.
