You may have noticed that the market size of stablecoins is growing rapidly.
Many people choose stablecoins forremittances, attracted by their near-instant speed andtransaction fees below 1%. However, behind these advantages lies a key issue.
Have you really calculated the spread cost when buying and selling stablecoins with fiat? This “invisible fee” may far exceed your imagination.
Before diving into stablecoins, you first need to clearly understand all the fees in traditional bank remittances. These fees are transparent but interconnected, and the total cost may exceed your initial impression.
When you initiate an international remittance from a bank, the first fee is the wire transfer fee. This fee is charged by your sending bank for processing the transaction.
Most major international banks have fairly standard outgoing wire fees. For example, initiating an international wire from Bank of America or HSBC typically costs about$45.
| Bank Name | International Outgoing Wire Fee |
|---|---|
| Bank of America | $45 (average) |
| HSBC Bank | $45 (average) |
| Citibank | $45 (average) |
Additionally, your funds may pass through one or more intermediary banks before reaching the final destination. These banks also charge service fees for handling your remittance, usually between$15 and $50. This fee is deducted directly from your principal, and you often cannot predict it in advance.
This is the largest “hidden cost” in traditional remittances. The exchange rate provided by the bank is not themid-market rate you see on Google or XE.com. Banks add a profit margin to this benchmark rate, known as a “markup.”
This markup is usually between0.5% and 5%. This means if you remit $10,000, you could lose $50 to $500 just from the exchange rate spread.
Finally, when funds arrive in the recipient’s bank account, the receiving bank also charges an incoming wire fee. This fee varies by bank.
As shown, some banks (like Charles Schwab) do not charge this fee, but most charge around $15, while banks like U.S. Bank may charge up to$25.
In summary, a seemingly simple bank remittance has total fees that are the sum of wire transfer fees, intermediary fees, exchange rate spreads, and incoming fees.

Now, let’s turn our attention to stablecoins. When you’re tired of traditional banks’ long waits and layered fees, stablecoin remittances seem like a perfect alternative. It does have very attractive surface advantages, but you must also understand its complete cost structure behind the scenes.
The two most prominent advantages of stablecoins are speed and low transfer network fees (Gas Fee).
First is speed. Unlike bank wires that take 1-5 business days, a stablecoin transaction usually confirms in minutes and is not limited by holidays or business hours, truly achieving anytime transfers.
Second is Gas fees. If you choose the right blockchain network, transfer costs can be very low. The TRC-20 network is currently the most common choice for individual users because its fees are far lower than Ethereum’s ERC-20 network.
Note: Gas fees are paid to blockchain network miners or validators for processing your transaction; they do not belong to any trading platform.
| Feature | ERC-20 (Ethereum) | TRC-20 (TRON) |
|---|---|---|
| Transaction Fees | Higher, from a few dollars to over $20 | Very low, usually between $1-2 |
Choosing the TRC-20 network for stablecoin remittances does make the direct cost per transfer far lower than bank wire fees. However, this is just the beginning of the story.
This is the first and most critical hidden cost you encounter. The so-called “on-ramp” is the process of buying stablecoins (like USDT) with fiat currency (like USD). In this process, you almost never get USDT at a 1:1 exchange rate.
This difference is called a premium.
Take a real-world example: suppose you need to remit from mainland China. You might transfer funds through compliant channels to a platform supporting fiat trading (such asBiyapay), then use the USD in your account to buy USDT. At this point, you will find the price may not be 1 USDT = 1.00 USD, but:
1 USDT = 1.01 USD
This means you pay an extra 0.01 USD for every 1 USDT. If you buy 10,000 USDT, just this on-ramp step costs you $100 (1% premium).
Why does a premium occur?
- Market Demand: When risk aversion is high or trading demand is strong, more people buy USDT, pushing its price above $1.
- Platform Costs and Profits: Platforms providing fiat trading services need to cover operational costs and earn profits, passing this on toconversion prices.
- Risk Factors: Different stablecoins have varying risk perceptions. In the past, TrueUSD (TUSD) experiencedpremiums up to 7% due to market factors, trading at $1.07.
When your recipient receives USDT, they need to convert it back to fiat for daily use. This process is called “off-ramp” and also has hidden costs, namely a discount.
Opposite to on-ramp, when selling USDT, the recipient usually cannot get a 1:1 rate either.
Continuing the example above, your recipient in the US sells the received 10,000 USDT through a platform likeBiyapay. The price they see may not be 1 USDT = 1.00 USD, but:
1 USDT = 0.99 USD
This means they lose 0.01 USD for every 1 USDT sold. Selling 10,000 USDT, they actually get only $9,900, incurring another $100 (1% discount) cost.
Key Point: Total Spread is the Real Cost Your true remittance cost must never just look at the intermediate transfer Gas fee. It must be the sum of “on-ramp premium” and “off-ramp discount.” In the above case, your total spread cost is 1% + 1% = 2%, or $200. This number already far exceeds the bank’s fixed wire fee.
Besides the core on/off-ramp spreads, consider some other fees.
Overall, the real cost of stablecoin remittances is far more complex than “low Gas fees.” The on/off-ramp spreads at both ends are the core determining total fees.

Theoretical analysis is always somewhat abstract; let’s calculate and compare the true total costs of both remittance methods through a specific case.
Assume you are in mainland China and need to remit funds to family in the US.
Now, we break down all fees you and the recipient bear under both paths step by step.
When choosing traditional banks, fees are transparent and predictable. Based on our earlier chapter analysis, total costs consist of:
10,000 USD * 0.5% = 50 USDTotal Cost Estimate Adding the above items, your total bank remittance cost is approximately:
45 + 20 + 50 + 15 = 130 USD
Now, let’s look at stablecoin remittance costs. To ensure compliance and safety, we use a platform supporting fiat trading like Biyapay as an example.
10,000 USDT * 1.2% = 120 USD10,000 USDT * 0.1% = 10 USD10,000 USDT * 1.0% = 100 USD10,000 USDT * 0.1% = 10 USDTotal Cost Estimate Adding all links’ costs, this stablecoin remittance total is:
120 + 10 + 2 + 100 + 10 = 242 USD
⚠️ Risk Warning on P2P Trading You might think: if using P2P (peer-to-peer) trading, can I find lower spreads? Theoretically possible, but you must be aware of the huge risks.P2P trading lacks central regulation, bringing extra uncertainty:
- Bank Account Freezes: If your counterparty involves illegal activities, law enforcement may trace and freeze related bank accounts.
- Crypto Scams: You may encounter scammers posing as real sellers; once you pay, they disappear.
- Tax Implications: P2P trading may attract tax authority scrutiny for evading regulation.
Taking these risks to save a little spread is not worth it for most people.
Now, put the total costs of both methods together; the result is clear.
| Fee Item | Traditional Bank Remittance (USD) | USDT Remittance (USD) |
|---|---|---|
| Total Cost | ~130 | ~242 |
| Arrival Time | 1-5 business days | About 10 minutes |
The conclusion is very clear: In this $10,000 remittance case, although banks are slower, their total fee (about $130) is far lower than USDT remittance’s total cost (about $242). The seemingly low $2 Gas fee in USDT is completely swallowed by the $220 total on/off-ramp spread.
This reveals a core fact: for medium-amount remittances most ordinary users do, when all hidden costs are included, traditional banks still have significant advantages in fees.
Now you understand: although stablecoin remittances are extremely fast, when all hidden costs are factored in, traditional banks often have more competitive total fees and security for medium amounts.
Your choice should be based on specific needs:
Ultimately, your decision hinges on one thing: before transferring, you must estimate USDT’s “total on/off-ramp spread”; this is its real cost.
Not necessarily. The key is calculating the total “on-ramp premium” and “off-ramp discount” costs. For small remittances, this total spread may be lower than banks’ fixed fees. But for medium to large remittances, banks are usually more cost-effective.
The cost principle is the same. Whether using USDC or other stablecoins, core costs come from fiat on/off-ramp spreads. Spreads for different stablecoins vary with market liquidity and demand.
You can directly view on your chosen trading platform or service provider.
Simultaneously compare “buy USDT” and “sell USDT” USD quotes. The gaps between these two prices and $1.00 are the real spread costs you pay.
This is mainly determined by market supply and demand. When buyers outnumber sellers, USDT’s price exceeds $1, creating a premium. Conversely, when sellers outnumber buyers, the price falls below $1, forming a discount.
