USAT, Tether’s compliant stablecoin aimed at the US market, reached a circulating supply of 140.85 million tokens at the end of April 2026 — an increase of roughly 6.4x from the prior month. According to an attestation from custodian Anchorage Digital Bank, the corresponding reserves stood at $141.17 million, fully backed by cash and reverse repo agreements collateralized by US Treasuries. This marks USAT’s first order-of-magnitude jump in a single month since launch, and signals that Tether’s second stablecoin product line — built specifically for the US regulatory framework, separate from USDT — is starting to gain traction.
Editorial take: what this means for the card in your wallet
Let’s start with the bottom line — for the vast majority of USDT virtual card users, this news won’t change your top-up process within the next 7 days. The USDT (₮) top-up path, BIN, and exchange-rate conversion you currently use remain untouched. USAT is an additional Tether product, not a replacement for USDT.
Two types of users are worth distinguishing here:
- Users of Asia-Pacific card lines funded primarily with USDT: this includes our editor’s pick MPCard Asia Elite, as well as Bybit Card and RedotPay. The funding asset for these cards remains USDT — USAT’s growth has no bearing on you. No action needed within 30 days.
- Users focused on US compliance who are considering US issuers long-term: USAT’s significance is that it’s the first time Tether has a “regulatorily clean” dollar stablecoin that can connect with US-licensed institutions. If this track proves out, it could eventually give rise to US card products natively supporting USAT. But that’s a 90-day-plus story — there is currently no corresponding card you can apply for.
Within the 90-day window, what’s really worth watching is whether USAT’s supply growth is coming from genuine settlement demand or from Tether’s internal market-making/reserve management. At 140 million tokens, USAT is still a rounding error next to USDT’s hundred-billion-dollar scale — the 6.4x monthly growth figure itself reflects a small base.
Historical comparison: where it resembles USDC and PYUSD — and where it doesn’t
USAT makes more sense when placed in the recent history of stablecoins.
In March 2023, USDC briefly depegged to $0.87 due to exposure to deposits at Silicon Valley Bank, exposing the risk of relying on a single reserve bank. USAT’s attestation specifically emphasizes that its reserves consist of cash plus US Treasury reverse repos, held in custody by Anchorage — a federally chartered digital asset bank — which is a structural response to that earlier crisis of confidence. The logic: make reserves as “boring” as possible to make them safer.
A closer parallel is PayPal’s 2023 launch of PYUSD: a major player using a compliance narrative to enter the US market amid the USDT/USDC duopoly. PYUSD’s circulating supply also saw high-multiple growth early on, before growth slowed and it settled into the hundreds-of-millions range long-term. USAT’s current trajectory closely resembles PYUSD’s early days — high multiple, low base, strong compliance backing. The difference is that USAT is backed by Tether’s own liquidity network, which in theory makes it easier to funnel existing USDT users toward it.
Similarity: both use “reserve transparency” as their selling point. Difference: USDC and PYUSD are Tether’s competitors, while USAT is Tether competing with itself — it exists to solve the problem of USDT being unable to enter licensed US channels.
Regulatory perspective: USAT exists to “get through the door”
USAT’s entire reason for existing is that USDT has long been treated as a gray-area asset by US regulators, making it difficult for licensed institutions to adopt directly. Tether’s strategy: USDT continues to serve global offshore demand, while USAT is built specifically to interface with the US compliance framework.
The practical boundaries for U-card users need to be spelled out clearly:
- US-based users: Using USDT to top up virtual cards remains a gray area with inconsistent regulation across states — see our US Compliance Guide for details. USAT’s growth does not change this situation — it serves institutional settlement, and no retail card product has materialized yet.
- Asia-Pacific users: USAT is a US-market matter with no direct bearing on stablecoin regulations in Hong Kong or Singapore. If you use cards in these jurisdictions, refer to the Hong Kong Compliance Guide and Singapore Compliance Guide — USDT remains the mainstream funding asset.
In short: USAT is currently an “institutional-layer compliance tool,” still some distance from a card retail users can actually swipe.
Milestones worth watching next
- The next Anchorage attestation: check whether USAT’s reserve structure maintains “all cash + T-bill reverse repo” and whether supply growth continues. Any shift toward non-cash or non-Treasury components would be a downgrade signal.
- Whether any issuer emerges that natively supports USAT: none currently exist. The real inflection point for retail users will be when a US-licensed institution announces it accepts USAT deposits.
- Whether Tether officially discloses USAT’s use cases: whether growth stems from market-making or genuine settlement will determine whether this line can scale.
- Whether USDT’s own supply is being cannibalized: if USDT and USAT move in opposite directions, that would indicate internal migration rather than net new growth.

Editorial recommendations
- If you hold a card like MPCard, Bybit Card, or RedotPay funded via USDT: no action needed. USAT’s growth doesn’t affect your top-up path.
- Asia-Pacific users planning to apply for a new card: continue using the existing USDT process to choose a card — see 5 U-Cards Worth Getting in 2026. No need to wait for USAT.
- Users focused on long-term US compliance: add USAT to your watchlist, but there is currently no corresponding retail card you can apply for. Don’t act early just because of the “Tether US stablecoin” narrative. It’s not too late to reassess once a licensed issuer announces USAT integration.
Bottom line: USAT is Tether’s card for knocking on the US regulatory door — it’s not a new tool for retail U-card users. Fine to watch, no need to change your process.
