Total stablecoin supply has crossed $300 billion for the first time, but The Block’s latest report highlights a telling contrast: overall growth has stalled, with nearly all net new supply flowing to Tether (USDT), while bank-backed and GENIUS Act-compliant new entrants have struggled far more than the market expected. In other words, rather than the “changing of the guard” that regulators envisioned, the incumbent issuer has continued to consolidate its position during a compliance vacuum. This structural shift deserves more attention from USDT cardholders than the round-number milestone itself.
Editorial Take: What This Means for Your USDT Card
Bottom line up front: for the vast majority of USDT virtual card users, this is neutral-to-positive news. No action required.
The operational chain behind a USDT virtual card is: “you top up with USDT → the card issuer holds/converts it → Visa/Mastercard handles settlement.” The biggest risk to this chain is not USDT’s price (it is pegged to $1), but rather the underlying settlement currency suddenly losing liquidity or being delisted by the issuer. Tether’s expanding share means USDT depth on exchanges and in OTC settlement is becoming more concentrated and thicker — meaning card issuers face lower slippage and latency risk when converting and settling.
Breaking it down by card:
- MPCard’s Asia Elite variant is built around USDT top-ups as its core use case. Concentrated market share is a positive for “USDT-first” routing like this — issuers don’t need to worry about fragmentation of liquidity in their primary settlement currency.
- Bybit Card and RedotPay, which are exchange- and wallet-based cards that use USDT as their primary settlement asset, also benefit from deeper underlying concentration.
- On the flip side, cards that lead with USDC or multi-currency positioning should watch the “bank-backed stablecoins off to a slow start” subplot — if compliant bank stablecoins fail to gain traction, some products marketed as “compliance-first stablecoin” may face currency switches or fee adjustments.
Timeline expectations: within 7 days, no perceptible change; within 30 days, watch whether issuers adjust their supported currency lists; within 90 days, the real variable is the GENIUS Act’s implementing rules — see below.

Historical Comparison: Different from the 2023 USDC Depeg and MiCAR
This situation is comparable to two historical events, but fundamentally different from both.
The brief USDC depeg in March 2023 was a liquidity panic — the Silicon Valley Bank collapse cast doubt on part of USDC’s reserves, briefly pushing the price to around $0.87. People holding USDC cards at the time faced real risk. This situation is entirely different: $300 billion is a supply all-time high, with no depeg, no bank run — it is a structural share shift, not a credit event.
Compared to the EU’s MiCAR legislation taking effect in 2024, that was a story of regulators actively tightening the rules and forcing compliant currencies to the top. After MiCAR, some platforms did delist non-compliant stablecoins. The GENIUS Act situation is almost the opposite — the legislative framework exists, but compliant new entrants are “off to a harder start than expected,” meaning the regulatory-mandated changing of the guard has not happened automatically. The market is still voting with its feet toward the currency with the deepest liquidity.
Common thread: both cases involve the tension of “regulators pushing A, market continuing to use B.” The difference: under MiCAR, B was forcibly delisted, whereas this time B (USDT) is only getting larger.
Regulation and Compliance: Where the GENIUS Act’s Gray Areas Lie
The GENIUS Act is the US federal framework for payment stablecoins, requiring issuers to hold licenses, maintain transparent reserves, and submit to audits. The problem is that having a framework does not mean having an ecosystem — bank-backed compliant stablecoins need time to build liquidity, get listed on exchanges, and line up settlement partners. None of that happens automatically because a law was passed.
For cardholders, the current boundaries are:
- Clearly permitted: Holding and using a USDT card for consumer payments outside the United States is not directly subject to the GENIUS Act.
- Gray area: Whether US domestic users making payments with non-GENIUS-compliant stablecoins (including USDT) will face restrictions long-term depends on future implementing rules.
- Clear direction of tightening: Future US-market compliant products will very likely require settlement in a licensed stablecoin.
US-based users should pay particular attention to this policy track; see US Compliance Overview. If you are based in Asia-Pacific, your settlement and regulatory risk profile is entirely different — Singapore Compliance Guide and Hong Kong Compliance Overview are worth reading side by side.
Key Milestones to Watch Going Forward
- Tether’s quarterly reserve report: Monitor the Tether Transparency page for the next update — check whether expanding market share is accompanied by changes in reserve composition.
- GENIUS Act implementing rules: Whether bank-backed stablecoins can build usable liquidity within the next one or two quarters is the key indicator of whether a “compliance-driven changing of the guard” will actually happen.
- Growth curve after $300 billion: If total supply plateaus around $300 billion, it signals that incremental growth has peaked and the market is entering zero-sum competition — this typically means intensified fee competition among card issuers, which benefits users.
- Major exchange stablecoin listing/delisting announcements: Any change in settlement currency support will show up on the exchange side first.
Editorial Recommendations
- Users holding MPCard, Bybit Card, RedotPay, or other USDT-core cards: no action needed. Concentrated liquidity in the underlying currency is a positive for you. This news does not constitute a risk signal.
- US-based users primarily using USDC or multi-currency cards: Watch for GENIUS Act implementing details, but there is nothing you must do immediately — do not rush to switch currencies based on a “growth stalls” headline.
- Users planning to apply for a new USDT card: Proceed normally. Concentrated market share actually reduces the risk of the primary currency being delisted. When comparing cards, prioritize fees and settlement currency — see Lowest-Fee Card Comparison.
One line summary: $300 billion is a milestone number, but the real signal for cardholders is “USDT is more stable on the settlement side” — not “time to panic.”
