In recent days, on over-the-counter (OTC) trading platforms of major cryptocurrency exchanges, the exchange rate of USDT to Chinese yuan has shown a noticeable premium. For instance, on April 4, Huobi’s OTC platform listed USDT at 6.79 CNY, while the official USD exchange rate was around 6.56 CNY — a significant 3% premium. This phenomenon raises an important question: Does this premium signal a surge in off-exchange capital inflow? Let’s explore the mechanics behind USDT's stability, the causes of its premium, and what this means for market dynamics.
How USDT Maintains Its Stability
As a critical bridge between fiat currency and digital assets, USDT (Tether) operates in two primary markets:
- Crypto-to-USDT markets — including centralized exchanges and DeFi platforms where users trade Bitcoin, Ethereum, and other cryptocurrencies for USDT.
- USDT-to-USD redemption market — where USDT is exchanged 1:1 for U.S. dollars, primarily through Tether’s official redemption service, large OTC desks, or compliant exchanges offering USDT/USD pairs.
While market forces determine USDT’s value against other cryptocurrencies, Tether must maintain a 1:1 parity with the U.S. dollar to preserve its role as a stablecoin. To support this, Tether officially guarantees redemption — but with significant barriers.

For individuals, direct redemption through Tether is impractical: the minimum threshold is $100,000 USD, with a fee of either $1,000 or 0.1% of the transaction amount, whichever is higher. This makes it inaccessible to retail investors.
Moreover, Tether’s [User Terms] include a crucial clause:
“Tether reserves the right to delay redemptions if its reserve assets face liquidity issues or losses. Tether also reserves the right to redeem users with securities or other reserve assets it holds.”
This means that even if you hold USDT, Tether may not deliver cash — instead offering alternative assets. Given that Tether does not fully disclose its reserve composition and likely doesn’t hold 100% cash backing, its ability to maintain parity relies heavily on market-making activities.
Tether leverages high-liquidity exchanges like Bitfinex, Kraken, and FTX, which together process over $150 million daily in USDT/USD trading volume. With Tether’s total issuance exceeding $40 billion, this level of trading activity allows effective price stabilization around the $1.00 mark.
Why Is USDT Trading at a Premium Against CNY?
In China and other restricted markets, there is no official on-ramp for converting USDT directly into CNY via regulated exchanges. Instead, users rely entirely on decentralized OTC networks, where prices are determined by supply and demand.
When USDT trades above the official USD/CNY exchange rate — such as 6.79 CNY vs. 6.56 — it indicates one of two scenarios:
- Increased demand for USDT in local markets, where buyers outnumber sellers.
- Capital flight from volatile cryptocurrencies into stablecoins, driven by market uncertainty.
Both reflect shifts in market sentiment. A premium suggests either new investors entering the crypto space using local currency or existing traders seeking safety by converting holdings into USDT.
Historically, extreme premiums have occurred during market stress. On March 12, 2020 — “Black Thursday” — panic selling drove USDT’s CNY price up to 7.8 CNY, as traders rushed to protect their capital from crashing crypto prices.
Today’s 3% premium coincides with BTC falling from $60,000, suggesting that much of the demand comes from in-market traders shifting into stablecoins, rather than fresh off-ramp inflows.
Why Doesn’t Arbitrage Eliminate the Premium?
A 3% arbitrage opportunity should, in theory, be quickly exploited: buy USDT cheaply via Tether using USD, sell it at a higher price in the CNY OTC market, convert proceeds back to USD, and repeat.
Yet this doesn’t happen at scale. Two key reasons explain why:
1. Foreign Exchange Controls
China enforces strict capital controls: individuals are limited to $50,000 USD in annual foreign exchange quotas, and international wire transfers are closely monitored. Most retail users cannot legally transfer large sums abroad to purchase USDT directly from Tether.
2. Risk of Receiving “Dirty Money”
Even if someone manages to acquire USDT and sell it OTC for CNY, they risk receiving funds linked to illicit activities — such as money laundering or fraud. This can lead to bank account freezes, investigations, or legal trouble. The potential penalties outweigh the profit from arbitrage.
Thus, despite the apparent opportunity, systemic barriers prevent efficient price convergence.
Who Is Driving the Current Demand?
While macro factors play a role, specific market behaviors shed light on today’s premium:
- Veteran traders are “mining” DeFi protocols requiring large amounts of stablecoins. For example, large-scale yield farming campaigns — such as those involving FEI protocol — have seen wallets deploying over $1 billion in stablecoin liquidity, partly funded by borrowed or acquired USDT.
- Newcomers are entering via trending projects like Filecoin, which has gained mainstream attention beyond typical crypto circles.
- OTC operators face increased regulatory scrutiny, especially regarding anti-money laundering (AML) compliance. As traditional OTC desks scale back due to enforcement actions, supply tightens — further pushing up prices.

This mix of reduced OTC liquidity and rising institutional-grade DeFi activity creates a perfect storm for sustained premiums.
Frequently Asked Questions (FAQ)
Why is USDT more expensive on Chinese OTC platforms?
Due to capital controls and limited access to direct USD-USDT conversion, demand often exceeds supply in local markets, leading to price premiums.
Can I profit from the USDT premium through arbitrage?
In practice, no — strict foreign exchange regulations and risks of receiving blacklisted funds make large-scale arbitrage unfeasible for most individuals.
Does a high USDT premium mean more people are investing in crypto?
Not necessarily. While new entrants contribute, the current premium is largely driven by existing traders moving into stablecoins during market volatility.
Is USDT still backed 1:1 by USD?
Tether claims full backing but holds a diversified reserve including commercial paper, bonds, and other assets. Full transparency remains limited.
Could tighter regulation reduce the USDT premium?
Yes — if compliant on-ramps expand in restricted regions, or if peer-to-peer trading becomes safer and more accessible, price disparities would likely shrink.
What happens when the premium disappears?
A return to parity usually signals stabilized market conditions — either reduced fear in crypto markets or improved liquidity in local trading ecosystems.

The current USDT premium reflects a complex interplay of regulatory constraints, trader behavior, and macroeconomic sentiment. While it may appear as a sign of mass adoption, deeper analysis reveals that much of the demand stems from strategic moves within the existing crypto ecosystem, particularly around risk management and yield generation.
As global financial regulations evolve and decentralized finance matures, understanding these dynamics becomes essential for both new entrants and seasoned participants.
