The USDT premium in Taiwan has become a well-known phenomenon among local crypto traders. For those actively buying USDT with TWD on domestic exchanges, it's common to see USDT priced 0.3% to 0.8% higher than the USD/TWD exchange rate—a counterintuitive reality that raises questions: Why is a digital dollar more expensive than the real thing? And can ordinary investors profit from this anomaly?
This article dives into the structural roots of the USDT premium, explains how retail traders can legally participate in arbitrage opportunities, and explores why the situation persists despite its clear inefficiencies.
Why Is USDT More Expensive Than USD in Taiwan?
At first glance, it seems illogical. USDT is designed to be a 1:1 digital representation of the U.S. dollar. Tether, its issuer, allows redemptions at par (1 USDT = 1 USD) with only a 0.1% fee. So why doesn’t someone simply buy USD, convert it to USDT, and sell it in Taiwan for a risk-free profit?
The answer lies in foreign exchange controls imposed by Taiwan’s central bank.
The Bottleneck: Central Bank Foreign Exchange Caps
Under current regulations, Taiwanese corporations—including crypto exchanges—are limited to converting only $50 million USD per year from TWD to USD through banks. Once this cap is reached, they cannot legally acquire more U.S. dollars to settle transactions with Tether.
Here’s how the standard USDT issuance process works:
- A user deposits TWD into a local exchange.
- The exchange converts TWD to USD via a bank.
- The exchange wires USD to Tether’s bank account.
- Tether issues new USDT to the exchange’s wallet.
- The exchange credits the user with USDT.
But here's the catch: Tether does not accept TWD—only USD. Without access to USD due to the central bank’s cap, exchanges cannot replenish their USDT supply, creating a structural shortage.
This bottleneck affects more than just USDT/TWD pairs. It ripples across all crypto-to-TWD markets like BTC/TWD or ETH/TWD, where sellers often demand payment in USDT (i.e., "stablecoin-only" trading). Even if an exchange collects TWD from buyers, it may lack sufficient USDT to fulfill trades—leading to two possible outcomes:
- Wider bid-ask spreads, forcing users to wait for natural matching between buyers and sellers.
- Liquidity drying up, pushing users to transfer funds offshore for better pricing and execution.
As a result, many Taiwanese investors bypass domestic platforms entirely, withdrawing USDT to international exchanges such as OKX or Binance—effectively draining local liquidity and weakening the domestic crypto ecosystem.
How Is USDT Still Available Locally?
Despite the supply crunch, most major Taiwanese exchanges continue offering USDT—albeit at a premium. Where does this supply come from?
Two primary sources keep the market afloat:
- Exchanges using creative (and often opaque) methods to source USD or directly acquire USDT from overseas.
- Retail arbitrageurs ("brick movers") who exploit cross-border pricing differences.
Let’s focus on the second group—the individual traders turning this systemic flaw into personal gain.
The Arbitrage Loop: Turning Currency Gaps Into Profits
Retail investors can legally participate in what’s known as “brick moving” (cross-border arbitrage) by leveraging their personal foreign exchange allowance.
Each individual in Taiwan is allowed to convert up to $5 million USD per year into foreign currency—far exceeding corporate limits. Here’s how savvy traders use this rule:
Step-by-Step Arbitrage Process:
- Buy USD at the prevailing bank rate (e.g., 30.82 TWD/USD).
- Wire USD to an overseas exchange that supports direct USDT minting (e.g., OKX).
- Convert USD to USDT at 1:1.
- Transfer USDT back to a Taiwanese exchange.
- Sell USDT at the local premium (e.g., 31.05 TWD/USDT).
With total transaction costs (fees + spreads) around 0.2%, net profits per cycle typically range from 0.1% to 0.6%, depending on market conditions.
While these returns may seem small per round trip, their frequency transforms them into compelling annual yields.

Annualized Returns: From Pennies to Percentages
Assuming one arbitrage cycle takes three business days, you could execute roughly 100 rounds per year.
Even at a conservative 0.25% profit per round, the compounded annual return reaches:
0.25% × 100 = 25% annualized return
In bullish or volatile periods, when premiums widen and opportunities increase, returns can exceed 100–150% per year—all with minimal market risk, as both legs of the trade are executed at known prices.
This makes the strategy especially attractive for retail investors seeking low-volatility, high-frequency yield generation without exposure to crypto price swings.
Why Doesn’t the Central Bank Lift the Cap?
From a macroeconomic perspective, Taiwan’s central bank remains hesitant to remove foreign exchange limits for several interconnected reasons:
1. Concern Over Capital Flight
Allowing unlimited USD conversion could accelerate outflows of foreign reserves, especially if funds flow into unregulated offshore crypto ecosystems rather than domestic economic activity.
2. Lack of Economic Value Capture
Most trading volume leaves Taiwan immediately after onboarding. The central bank sees little domestic benefit—no tax revenue, no job creation, no financial innovation spillover.
3. Regulatory Risk Aversion
Opening the floodgates means accepting responsibility. If a crisis emerges (e.g., a major exchange collapse), regulators could face political backlash. Inaction, meanwhile, carries no immediate cost.
These factors create a self-reinforcing cycle:
No USD access → Poor liquidity → High spreads → Users leave → No incentive to reform
It’s a classic chicken-and-egg problem: healthy markets require capital inflows, but capital won’t flow without healthy markets.
Frequently Asked Questions (FAQ)
Q: Is this arbitrage legal?
Yes. As long as you stay within your personal $5 million annual FX conversion limit and report income appropriately, cross-border arbitrage is fully compliant with Taiwanese law.
Q: What are the main risks?
Primary risks include:
- Transaction delays (bank processing times)
- Exchange withdrawal limits
- Smart contract or wallet transfer errors
- Tax implications from repeated gains
Market risk is minimal since both buy and sell prices are locked in before execution.
Q: Can I automate this process?
Fully automated systems are risky due to custody and compliance concerns. However, many traders use scripts to monitor spreads and alert them when arbitrage windows open.
Q: Does this work with other stablecoins?
Possibly—but USDT dominates due to its deep liquidity and direct redemption mechanism with Tether. Alternatives like USDC lack equivalent on-ramps in Asia.
Q: Are there tax consequences?
Profits may be considered taxable income depending on frequency and scale. Consult a local accountant familiar with digital asset regulations.
Q: Will this opportunity disappear?
As long as foreign exchange controls persist and demand for offshore trading remains strong, the premium will likely endure. Structural reforms would be needed to close the gap permanently.
Final Thoughts: An Imperfect System With Real Opportunities
The USDT premium in Taiwan isn't a glitch—it's a symptom of misaligned incentives between regulators, financial institutions, and retail investors.
While the central bank prioritizes stability over innovation, individuals have found ways to navigate the constraints and generate outsized returns.
For retail traders, this environment presents a rare chance to earn market-independent yields through disciplined execution and financial literacy.
Rather than waiting for systemic change, the most proactive investors are already acting—using legal channels, personal allowances, and global infrastructure to turn policy bottlenecks into personal profit engines.
