The Week Singapore Banned Stablecoin Yield, a 6% Yield App Opened in Singapore
On September 1, Singapore's central bank proposed prohibiting stablecoin issuers from paying holders anything calculated by reference to how much of the coin they hold. That same day, an app offering a 6% dollar savings rate on a stablecoin balance opened staged access to users in Singapore.
Both facts are true. Neither the regulator nor the app is confused about the other. And the space between those two announcements is the most instructive thing in stablecoin policy right now, because it shows exactly where the rules land and exactly where the money has already moved.
The Monetary Authority of Singapore published a consultation paper proposing amendments to the Payment Services Act that would turn its 2023 stablecoin framework into actual law. A licensed issuer would hold 100% reserves against circulating supply, redeem at par, and — the newest clause — would be barred from paying interest, yield, or any benefit tied to a customer's holdings. The consultation closes October 16.
That last provision reads like a straightforward consumer rule. It isn't. It's a bank rule.
A yield ban is a deposit-competition rule wearing a consumer-protection coat
Strip away the language and the logic is simple. A dollar balance that pays interest, sits on a phone, moves globally in seconds, and carries no deposit insurance is a bank deposit with the safety net removed and the friction removed too. Regulators have spent two years staring at that product and deciding they don't want it sold to retail.
Singapore is not alone in the conclusion. The GENIUS Act in the United States and MiCA in Europe both landed on a version of the same restriction, which is why CoinDesk framed the Singapore draft as convergence rather than divergence — three major jurisdictions independently deciding that a payment token should be a payment token.
The concession is real and worth making plainly. If issuers pay yield, they have to earn it, which means reaching for duration or credit in the reserve, which means the thing backing a "dollar" stops behaving like a dollar exactly when everyone wants theirs back. A run on a yield-bearing stablecoin is a bank run without a lender of last resort. MAS has read that history. So has everyone else.
But the ban has a target, and the target is the issuer. The yield left the issuer a long time ago.
The savings rate is not coming from the coin
Look at what actually launched. Ethena Pay went live September 1 on iOS and Android, with staged access rolling out across roughly four dozen countries — Brazil, Mexico, Kenya, the Philippines, Japan, the UAE, Australia, Singapore. Deposits arrive by bank transfer or in crypto, convert to USDe, settle on Avalanche, and come back out in the recipient's local currency. There's a virtual Visa card, generated in about a minute, spendable at Apple Pay terminals.
The headline number is the 6% dollar savings rate. The interesting part is how you get it.
You don't get it by holding the stablecoin. You get it by locking ENA, a completely separate token. Two thousand dollars of locked ENA or ten referrals earns the higher rate on balances capped at $15,000. Ten thousand dollars locked or fifty referrals raises the cap to $50,000, according to CoinDesk's account of the launch.
Read that structure against the MAS clause again. The proposed prohibition covers a benefit "calculated by reference to a customer's stablecoin holdings." A rate gated by a governance token lock, paid by an application rather than the issuer of record, referenced against a tier you bought your way into — that is a loyalty program with a treasury behind it. It is not interest on a stablecoin, at least not in the shape the drafters described.
I don't think this is a loophole anyone stumbled into. It's the shape every yield product will take once issuer-level yield is illegal in the three markets that matter, and Ethena shipped a working version of it the same day the draft appeared.
Coinbase already ran this experiment
None of this is theoretical. USDC pays nothing. Circle, the issuer, distributes nothing to holders. Coinbase, the distributor, pays a rewards rate on USDC held in Coinbase accounts, funded out of the economics it receives for distribution. That arrangement has operated in plain sight through the entire GENIUS Act debate, and it survives because the issuer isn't the one paying.
The lesson generalized fast. Reserve income is enormous, distribution is where the customer lives, and a rule aimed at issuers simply relocates the payment one layer outward. You can ban issuers from paying yield. You cannot easily ban an app from sharing its own revenue with users, not without writing a much broader rule about what any financial application may do with its margin.
Which raises the question MAS will face in the consultation window: does the prohibition follow the coin, or follow the issuer? The draft, as described, follows the issuer. If Singapore wants to close the gap, it has to reach past issuers into the applications, and that is a different regulatory project with a much larger footprint.
There is a defensible version of the broader rule, too. A supervisor could reasonably say that any entity holding customer funds and paying a rate on them is doing deposit-taking regardless of what it calls itself or which token gates the tier. Several jurisdictions have said something close to that about crypto lending platforms already. The trouble is that the same test catches brokerage cash sweeps, prepaid card rewards, and half of consumer fintech, which is why nobody has written it yet.
Singapore wants the plumbing, not the deposit competition
The other half of the consultation is the half that got less attention and may matter more. In 2023, MAS decided that only stablecoins issued wholly in Singapore could carry its label. The new draft reverses that: jointly issued coins can qualify if the risks are managed, and a limited number of foreign-issued coins regulated under comparable regimes will be recognized for wholesale cross-border use.
Wholesale. Cross-border. Those two words do a lot of work. Singapore is opening the door to foreign stablecoins as settlement infrastructure between institutions while keeping the retail deposit base fenced off from anything that pays a rate. It's a coherent position for a jurisdiction whose banks fund a large regional economy, and it's a fairly honest statement of what the yield ban is protecting.
The awkwardness is that retail users are not sitting still while institutions get their plumbing. Singapore appears in the first wave of Ethena Pay's rollout. So does the Philippines, where remittance costs make a card-and-savings app a genuinely different product than it is in Tokyo.
And the rollout order tells you who these apps are actually for. Brazil, Mexico, Kenya, the Philippines, the UAE — markets where the local currency depreciates, the banking rails are expensive, or the diaspora sends money home monthly. The United States, the EU, Canada and South Korea sit further down the schedule, which is exactly what you would expect from a product whose regulatory risk is highest where deposit protection is strongest.
That inversion is worth naming. The jurisdictions writing the strictest stablecoin rules are the ones these products reach last, and by the time they arrive the structure will have been battle-tested for a year somewhere with less enforcement capacity. Rules written first do not necessarily bind first.
The friction has moved from the coin to the user
Here is what someone in that first wave actually holds now. A USDC balance in one venue paying a distributor rate. A USDe balance in an app paying a tiered rate that depends on a token lock. Maybe a bank balance paying nothing. Three dollar-denominated positions, three different yields, three different caps, three different risk profiles, and no statement that shows them together.
That person is doing portfolio management whether they signed up for it or not, which is why the tracking layer keeps growing faster than the products themselves. Watching a savings rate that floats with perpetual funding markets alongside a spot balance and a locked governance position is the sort of thing The Crypto App exists to consolidate, and the need for it is a direct consequence of yield fragmenting across a dozen distributors instead of sitting on one coin.
The old version of this market was simple to regulate because it was simple to describe. One issuer, one coin, one reserve, one rate of zero. The new version has an issuer who pays nothing, an app that pays six, a governance token that gates the tier, a settlement chain chosen for cost, and a card network doing the last mile. Every one of those is a separate legal entity in a separate jurisdiction.
MAS has until October 16 to hear from the industry about a rule aimed at the one participant in that chain who has already stopped paying. The more interesting consultation is the one nobody has opened yet — the one about whether a regulator gets to tell an application what it may do with its own revenue, and what happens to the definition of a bank if the answer is no.
