20 USDC Pairs and 10 USD1 Pairs Removed Sept. 14
MEXC is removing 30 USDC- and USD1-denominated spot trading pairs in a single day after the markets failed to meet the exchange’s liquidity and trading requirements, marking an unusually broad consolidation of stablecoin-quoted markets.
The exchange said 20 USDC pairs would be delisted at 13:00 UTC on Sept. 14, followed by another 10 USD1 pairs one hour later at 14:00 UTC.
The USDC removals are ZBT/USDC, OPEN/USDC, PROVE/USDC, SAHARA/USDC, HYPER/USDC, KERNEL/USDC, BABY/USDC, ACT/USDC, TNSR/USDC, LPT/USDC, NMR/USDC, RSR/USDC, UMA/USDC, ZKC/USDC, MIRA/USDC, SIGN/USDC, ZKP/USDC, THE/USDC, USUAL/USDC and ILV/USDC.
The USD1 group consists of SAHARA/USD1, AAVE/USD1, TAG/USD1, AVAX/USD1, ASTER/USD1, MELANIA/USD1, PEPE/USD1, B/USD1, LA/USD1 and BANK/USD1.
SAHARA appears in both groups, meaning the action removes 30 individual markets covering 29 different base tokens.
MEXC said all open orders in the affected markets would be automatically canceled when trading ends. Importantly, the action applies to individual trading pairs rather than the underlying tokens themselves. Where supported, customers can continue trading the assets through other available spot pairs.
There is also no indication in the announcement that MEXC is withdrawing support for either USDC or USD1 as stablecoins. The exchange specifically described the decision as the result of its latest assessment of trading-pair liquidity and activity.
The move comes only days after MEXC made a separate set of risk-control changes to its IOST perpetual market, cutting maximum leverage from 50x to 20x and moving funding settlement to an hourly schedule. The two actions affect different products, but both show MEXC actively adjusting individual markets when their trading characteristics warrant intervention.
The scale of Monday’s spot-market cleanup is particularly notable because both quote assets remain significant stablecoins.
Circle reported $74.1 billion of USDC in circulation as of Sept. 10. USDC is backed by highly liquid cash and cash-equivalent reserves and has become a major settlement, trading and payments asset across centralized exchanges and blockchain networks.
Its size has also made it an increasingly important source of stablecoin liquidity outside centralized exchanges. A recent whale transaction, for example, used more than $85 million of USDC to accumulate Bitcoin through THORChain, illustrating how dollar tokens increasingly function as deployable cash across crypto markets.
USD1 is much newer but has also grown quickly. MEXC’s own market data recently put its capitalization at approximately $4.26 billion. The dollar-pegged token is associated with World Liberty Financial and is issued and redeemed through BitGo, which says USD1 is backed by short-term U.S. government Treasuries, dollar deposits and other cash equivalents.
The removal of 10 USD1 markets therefore does not necessarily imply weakness in USD1 itself. A stablecoin can have billions of dollars in circulation while individual token pairs built around it still fail to attract enough buyers, sellers and market makers to maintain efficient order books.
That distinction matters as stablecoin competition intensifies across exchanges. Binance is currently offering a 200,000 RLUSD campaign as it tries to attract balances in Ripple’s stablecoin, while other platforms are creating incentives around their preferred dollar-linked assets.
KuCoin has similarly used stablecoin yield incentives around KCUSD, highlighting how exchanges are increasingly competing not only for trading volume but also for the dollar-denominated liquidity customers leave on their platforms between trades.
MEXC’s latest decision shows the opposite side of that competition. Adding a stablecoin quote currency can create another market and another route for capital, but retaining that market only makes sense if enough traders actually use it.
Thirty Delistings Show the Limits of Stablecoin Fragmentation
The most interesting thing about this announcement is not any one of the tokens being removed.
It is that 30 stablecoin-denominated order books disappeared from the same exchange within one hour.
Crypto exchanges have spent years adding more quote currencies. At first, the logic is attractive. More stablecoins mean more choice, more deposit routes and more ways for customers to move directly between dollar-linked assets and cryptocurrencies without passing through another market.
But every additional pair fragments liquidity.
If the same altcoin trades against USDT, USDC, USD1 and several other stablecoins, the underlying demand for that token is divided across multiple order books. Unless trading activity is large enough to support all of them, some books eventually become thin.
That creates practical problems. Thin markets generally mean wider spreads, shallower order books and greater price impact when larger orders arrive. Maintaining an underused pair also consumes exchange and market-making resources while providing relatively little additional utility to customers.
The interesting contrast is that exchanges are simultaneously paying users to bring in more stablecoins while eliminating stablecoin markets that fail to achieve sufficient activity.
That is not contradictory.
Stablecoin balances are valuable because they represent immediately deployable capital. But an exchange does not necessarily need every stablecoin paired directly against every token. In fact, concentrating trading in fewer, deeper markets can produce better execution than maintaining a much larger menu of poorly used pairs.
That explains why even USDC’s roughly $74 billion circulation does not protect every USDC pair from delisting. Global stablecoin size and local order-book liquidity are completely different measurements.
The same applies to USD1. Reaching a multibillion-dollar market capitalization gives the stablecoin scale, but it does not guarantee that traders want to use USD1 specifically to buy AAVE, AVAX, PEPE or the other assets included in Monday’s cleanup.
For traders, the immediate consequence is operational rather than existential. Open orders disappear, trading bots using the affected symbols must be reconfigured and arbitrage routes that depended on those books need to move elsewhere.
There can also be a temporary concentration effect. Traders who previously split activity across several quote currencies may migrate toward the remaining markets, potentially improving depth there while reducing the number of available routes between assets.
This is why a pair delisting should not automatically be confused with a full asset delisting. Other exchanges have taken much more consequential actions, including forced conversion after a delisting, where customers can lose the ability to continue holding or withdrawing an asset through the platform.
There is no indication of that here. MEXC explicitly says the underlying tokens can remain tradable through other supported pairs.
Nor is the action comparable with an exchange completely winding down products and requiring users to redeem positions. This is primarily an order-book consolidation.
Still, the size of the cleanup makes it a useful market-structure signal.
Stablecoin competition is producing more dollar tokens, more exchange integrations and more incentives to attract balances. But there is a natural limit to how many parallel markets traders actually need.
MEXC’s 30-pair purge is a reminder that listing a stablecoin market is easy. Building enough sustained two-sided liquidity to justify keeping it is much harder.
If similar batches follow, particularly across USD1 or other newer quote currencies, the bigger story will be whether exchanges are beginning to reverse some of the pair proliferation of recent years and consolidate liquidity around a smaller number of genuinely active stablecoin markets.
