Singapore Proposes 100% Reserves and Yield Ban for Stablecoins

Singapore's monetary authority MAS has proposed new rules for stablecoin issuers. The draft requires full reserve backing for issued tokens and bans paying yield to holders, and the changes would apply to major players like Tether and Circle if they want to operate officially in a jurisdiction with billions in daily crypto trading.

What MAS Wants From Issuers

The regulator's draft requires stablecoin issuers to hold reserves that cover 100% of issued tokens. It's a standard that both the US, through the GENIUS Act, and the European Union, through MiCA, have rolled out in recent years, so Singapore is joining a global trend rather than inventing its own approach.

The second part of the proposal is tougher. MAS wants to ban issuers from paying stablecoin holders any yield, including interest on balances. That move limits a model some projects have favored, where a token doubles as both a payment instrument and a yield-bearing product resembling a bank deposit.

Put simply, a token should stay money, not a deposit. The regulator frames this as an effort to separate the payment function of stablecoins from investment products, which fall under a completely different oversight regime in Singapore.

Singapore isn't starting from scratch on stablecoins. The country has licensed payment tokens under its local Payment Services Act for several years, and the local XSGD stablecoin from StraitsX has operated under MAS oversight since 2020. The new draft looks more like a consolidation of accumulated experience into a clearer standard than regulation built from a blank page.

A Door Opens for Foreign Stablecoins

Beyond requirements for local issuers, MAS is opening a recognition process for stablecoins issued outside Singapore. Large tokens like USDT currently trade in the city-state without official regulated-asset status, even though exchanges and money changers handle them daily, and users rarely think about the difference in regulatory status.

Recognition of a foreign issuance would give such tokens access to bank accounts, licensed payment services, and institutional clients who currently avoid unregulated assets because of internal compliance limits. For Tether and Circle, that's a chance to gain a foothold in one of Asia's financial hubs without launching a separate local version of the token, something some issuers already do in other jurisdictions.

The regulator stressed that the framework aligns with US and EU approaches rather than standing as a unique Singapore standard. That matters for global issuers: the same reserves and reporting could satisfy requirements across several jurisdictions at once.

The stakes are high for Singapore too. The city-state has spent years positioning itself as Asia's financial hub for crypto companies, and clear stablecoin rules work as an argument in its competition with Hong Kong and the United Arab Emirates for the headquarters of major market players.

Consequences for the Big Issuers

For Tether, the yield ban looks neutral. The company already doesn't pay interest to USDT holders and earns profit from its reserves in US government bonds instead. It's tougher for projects that offered stablecoin holders built-in yield as a marketing hook to pull capital away from traditional savings products.

The 100% reserve requirement shouldn't surprise market leaders either. Tether and Circle already publish regular reports on reserve composition, so formal confirmation for Singapore's regulator probably won't require rebuilding their business model. Smaller issuers and algorithmic stablecoins that rely on partial or synthetic backing instead of a direct cash-and-bonds reserve face a tougher path.

Singapore isn't alone among Asian jurisdictions here. Hong Kong introduced its own licensing regime for stablecoins back in 2024, and Japan has required issuers to stick to a conservative bank-reserve model for years. For large players, that means operating under several similar but not identical rulebooks within one region at once.

The market took the news calmly. No sharp moves in USDT or USDC market capitalization followed the draft's publication, which points more to the move being expected than to indifference among market participants.

The memory of the TerraUSD algorithmic stablecoin collapse in 2022 still shapes regulators worldwide. That's why a direct cash-and-bonds reserve requirement, rather than backing through algorithms or other crypto assets, has become close to a mandatory condition for any new standard.

For smaller issuers, rules like these mean extra costs. Regular reserve audits, reporting to several jurisdictions at once, and giving up yield as a competitive edge all cost money that large players like Tether or Circle have long since budgeted for, while smaller companies are only starting to plan for it.

The Effect on Traders and USDT Holders

For an ordinary user holding USDT or USDC on an exchange or in a wallet, there are no direct consequences yet. The rules target issuers, not token holders. But over the long run, a regulated status reduces the risk of frozen reserves or a sudden loss of the dollar peg, the kind of event that periodically spooks the market after news about troubled stablecoins.

For the Ukrainian market, this matters more than it might seem, since USDT remains the main tool for P2P trading. The more transparently an issuer discloses its reserves, the lower the odds of panic during sharp swings in the hryvnia. Anyone planning to sell USDT for hryvnia in the coming months won't feel the effects of Singapore's initiative directly, but it adds weight to the broader trend toward regulated USDT and USDC over less transparent alternatives.

In practice, regulated status mostly affects listings. Major exchanges and payment providers increasingly choose which stablecoins to support based on whether the issuer holds official recognition in key jurisdictions. A token without that status gradually loses access to the biggest markets, even if it remains just as liquid on a technical level.

Where Global Stablecoin Regulation Is Heading

MAS is joining a long list of regulators synchronizing stablecoin requirements this year. The US GENIUS Act and the EU's MiCA already set a roughly similar template, and now Asia is catching up. The common denominator is similar everywhere: full reserves, transparent reporting, and limits on yield for private holders.

For the market, this means a gradual shrinking of space for unregulated or semi-transparent stablecoins. The MAS draft still has to go through public consultation, so the final version of the rules could differ from the initial proposal. But the regulator has marked the direction clearly, and the largest issuers already have experience adapting to similar requirements in other countries.

The next move belongs to market participants: submit feedback during the public consultation MAS typically runs for several months before finalizing rules. Until then, Tether, Circle, and other issuers will keep operating under current, less detailed norms.

The stablecoin market's total size keeps growing despite regulatory pressure, and that growth is exactly what's pushing supervisors to move faster. The more money flows through stablecoins every day, the costlier it gets for a regulator to leave the segment without clear rules.
