Sending Money Across Borders With Stablecoins: Is It Really Cheaper?

Stablecoins are often promoted as a cheaper way to send money across borders. Assets such as USDT and USDC can move through a blockchain around the clock without waiting for bank operating hours. On certain networks, the transaction fee can also be considerably lower than the cost of a conventional international transfer.

The process, however, does not necessarily end when the stablecoins arrive in the recipient’s wallet. A recipient in Indonesia will usually need rupiah that can be spent from a bank account or digital wallet. The stablecoins may still need to be sold, converted, and withdrawn.

The short answer is therefore: stablecoins can be cheaper, but they are not always cheaper.

A cost advantage is more likely when:

• the cost of buying stablecoins is low;

• the buy and sell spreads are narrow;

• the sender and recipient use the same supported network;

• the network is not congested;

• the asset withdrawal fee is reasonable;

• the recipient has an efficient way to convert the stablecoins into rupiah;

• the stablecoin remains close to its reference value;

• no unexpected charge appears when the rupiah is withdrawn.

A fair comparison should not stop at the blockchain gas fee. The more useful measure is the total amount paid by the sender compared with the net rupiah the recipient can actually use.

The Blockchain Fee Is Only One Part of the Transfer

A conventional remittance can include a transfer fee, foreign-exchange margin, intermediary charge, or payout fee. These costs are often presented together, allowing the sender to see the final amount expected to reach the recipient.

Stablecoin costs are distributed across several stages. Some may not appear as explicit fees because they are embedded in the difference between the buying and selling prices.

The main cost components include:

1. The cost of entering the crypto ecosystem

The sender must convert the original currency into a stablecoin. This may involve a trading fee, card charge, bank-transfer cost, payment-provider charge, or a difference between the stablecoin’s quoted price and its reference value.

2. The purchase spread

A stablecoin linked to US$1 may not always be available at exactly US$1. The available price depends on liquidity, the payment method, the size of the order, and current market conditions.

3. The platform’s asset withdrawal fee

Sending stablecoins to an external wallet may involve a withdrawal fee. The amount can differ by asset and network.

4. The network or gas fee

A blockchain requires a fee to process the transaction. The fee can be small on some networks but may increase when network activity is high.

5. The selling spread at the destination

The recipient must sell the stablecoins for rupiah. If liquidity is limited or demand is imbalanced, the selling price may fall below the reference value.

6. The rupiah payout fee

After conversion, the proceeds must still be withdrawn to a bank account or another supported payment channel. Withdrawal fees, minimum amounts, and additional processing time may apply.

This structure explains why a cheap blockchain transaction does not automatically create a cheap international transfer. The sender might save on the network fee but lose more through the purchase or cash-out spread.

The Relevant Benchmark Is the Full Cost of a Conventional Transfer

The World Bank’s Remittance Prices Worldwide database reported an average total cost of 5.71% for a surveyed amount equivalent to US$200 sent from the United States to Indonesia in the third quarter of 2025. For an amount equivalent to US$500, the average declined to 3.80%.

According to the Remittance Prices Worldwide methodology, total cost includes the fee paid by the sender and the foreign-exchange margin applied by the service provider. The World Bank surveys two standardized amounts, based on local-currency values broadly equivalent to US$200 and US$500.

The difference between 5.71% and 3.80% demonstrates an important point: the size of the transfer affects the percentage cost. A fixed US$5 fee represents 2.5% of a US$200 transfer, but only 1% of a US$500 transfer.

These figures are not current transaction quotes. The World Bank explains that Remittance Prices Worldwide data represents a snapshot during a particular collection period. Actual prices may differ depending on the provider, payment method, receiving method, exchange rate, and timing of the transfer.

An average does not mean every provider charges 5.71%. Prices within the same corridor can vary substantially. A stablecoin route should therefore be compared with a live quote available to the sender, rather than with the historical average alone.

How Does a Stablecoin Transfer Move From Sender to Recipient?

A cross-border stablecoin transfer can be divided into three main stages.

A. On-Ramp: Converting Ordinary Money Into Stablecoins

The sender first purchases stablecoins with the available currency. A sender in the United States might start with U.S. dollars. A sender in another country may need to convert the local currency before obtaining a dollar-denominated stablecoin.

Costs at this stage may include:

• trading fees;

• the purchase spread;

• bank-transfer charges;

• debit- or credit-card fees;

• payment-provider charges;

• a premium above the stablecoin’s reference value.

A platform may advertise a low trading fee while offering the stablecoin at a price above US$1. That price difference remains an economic cost even when it is not labelled as a fee.

B. Blockchain Transfer: Moving Stablecoins Through a Network

Once the stablecoins are available, the sender selects a network and enters the recipient’s address. The most visible costs at this stage are normally the withdrawal fee and network fee.

The cost and speed depend on:

• the selected network;

• current network congestion;

• the number of confirmations required;

• the platform’s withdrawal process;

• the minimum withdrawal amount;

• the operational status of deposits and withdrawals.

The sender and recipient must use the same asset and compatible network. USDT on Ethereum, Tron, Solana, and other networks uses different infrastructure. Sending an asset through a network that the recipient cannot support may result in the deposit not being credited or may require a recovery process that is not guaranteed to be available.

MEXC explains that withdrawal fees can vary by asset and network conditions. The amount displayed on the withdrawal page before confirmation is the relevant figure for an actual calculation. It represents the cost of withdrawing the crypto asset, not the total cost of delivering usable rupiah to the recipient.

C. Off-Ramp: Converting Stablecoins Into Rupiah

After receiving the stablecoins, the recipient must sell them and withdraw the proceeds. This is the stage most frequently excluded from claims about cheap blockchain transfers.

Off-ramp costs can be affected by:

• the stablecoin’s selling price against rupiah;

• available liquidity;

• the bid-ask spread;

• trading fees;

• slippage on a large order;

• the rupiah withdrawal fee;

• minimum and maximum payout limits;

• the time required for the money to reach a bank account.

The Bank for International Settlements, or BIS, recognizes that blockchain-based stablecoin transfers may be fast and carry low network fees. However, the BIS also states that a complete comparison must include on-ramp and off-ramp costs. In practice, these additional expenses can make stablecoin transfers as costly as, or more costly than, bank transfers, particularly for small amounts.

A US$200 Stablecoin Transfer Illustration

The following example shows how costs may accumulate across the transaction. The figures are hypothetical and do not represent current MEXC fees, a remittance provider’s rates, or a live transaction quote.

Lower-Cost Scenario

In this scenario, the recipient receives value equivalent to US$194.03. The difference from the starting amount is US$5.97, or approximately 2.99%.

A 2.99% effective cost is lower than the World Bank’s historical 5.71% average for the US$200-equivalent United States to Indonesia corridor in the third quarter of 2025. It only demonstrates that stablecoins can be cheaper if every assumption in the example is satisfied.

The calculation does not include:

• movement in the USD/IDR exchange rate;

• a premium when the stablecoin is purchased;

• deviation from the stablecoin’s peg;

• different fees across networks;

• account-verification delays;

• recovery costs if a transfer goes wrong;

• taxes or other obligations that may apply;

• price movement during the cash-out process.

The 2.99% result should therefore not be treated as an estimated cost for every user.

What Happens If the Off-Ramp Is More Expensive?

Now keep the same starting amount and transfer fee, but increase the stablecoin selling spread from 1% to 5%.

The calculation becomes:

• Starting amount: US$200

• After a 1% purchase spread: US$198

• After a US$1 transfer cost: US$197

• After a 5% selling spread: US$187.15

• After a US$1 payout fee: US$186.15

The recipient receives value equivalent to only US$186.15. The total difference rises to US$13.85, or approximately 6.93% of the original amount.

Under this scenario, the stablecoin route becomes more expensive than the World Bank’s historical average of 5.71% for the US$200-equivalent corridor. The main cause is not the blockchain fee. It is the destination’s cash-out price.

The two examples show how sensitive the final result is to off-ramp conditions:

• 1% off-ramp spread: effective cost of approximately 2.99%.

• 5% off-ramp spread: effective cost of approximately 6.93%.

• Difference between the outcomes: approximately US$7.88 on the same starting amount.

The sender should therefore examine conditions at the recipient’s end before initiating the transfer. The cheapest network does not necessarily produce the largest amount of rupiah.

Fixed Fees Affect Small Transfers More Heavily

Some blockchain and withdrawal charges are fixed nominal amounts. Their percentage impact therefore varies by transfer size.

If the combined withdrawal and network cost is US$2:

• it represents 4% of a US$50 transfer;

• it represents 1% of a US$200 transfer;

• it represents 0.4% of a US$500 transfer;

• it represents 0.2% of a US$1,000 transfer.

Stablecoins may be inefficient for very small amounts when fixed costs are high. For larger amounts, network costs may become relatively small, but slippage and cash-out limits can create new problems.

A large order may receive a worse average price if available liquidity is insufficient. The recipient may also need to convert the assets gradually because of transaction limits or risk controls. A larger transfer does not automatically make the entire route simpler.

Fast on the Blockchain Does Not Always Mean Fast to a Bank Account

Stablecoins can move between wallets within seconds or minutes, depending on the network. The relevant timeframe for the recipient, however, is how long it takes before the rupiah becomes usable.

The total process may include:

1. time required to purchase the stablecoins;

2. the platform’s withdrawal-processing time;

3. blockchain confirmation time;

4. the time required for the destination platform to credit the deposit;

5. time required to sell the stablecoins;

6. rupiah withdrawal processing;

7. processing by the bank or payment channel.

An on-chain transfer may finish quickly while the cash-out is delayed by verification, maintenance, transaction limits, or compliance checks. A conventional transfer service may sometimes provide the recipient’s expected rupiah amount and delivery time before the sender confirms the transaction.

Speed should therefore be measured from the moment the funds leave the sender until the recipient can use them, not only by the timestamp of the blockchain transaction.

Indonesian Rules Still Apply

Transferring stablecoins as digital assets is not the same as using them as a payment instrument in Indonesia. Bank Indonesia Regulation No. 17/3/PBI/2015, which remains marked as effective on Bank Indonesia’s website, requires rupiah to be used for cash and non-cash transactions conducted within Indonesia.

The regulation also provides several exceptions, including certain state-budget transactions, international grants, international trade, foreign-currency bank deposits, international financing, and other legally recognized transactions. The legal treatment of a transfer therefore cannot be determined solely by the involvement of a stablecoin.

The actual structure must be examined:

• whether the stablecoin is merely being transferred as an asset;

• whether it is being used to pay for goods or services in Indonesia;

• who performs the currency conversion;

• who handles the payout into rupiah;

• what permissions each service provider holds;

• how identity and source-of-funds checks are performed;

• which rules apply in the sender’s and recipient’s jurisdictions.

This article does not conclude that every cross-border stablecoin transfer is prohibited. Blockchain technology, however, does not remove legal obligations involving payments, money transfers, foreign exchange, consumer protection, taxation, or anti-money-laundering controls.

Risks That Do Not Appear in the Fee

Cost is not the only factor in choosing a transfer route. Stablecoins introduce operational and financial risks that differ from those of conventional transfers.

Peg Risk

A stablecoin aims to follow the value of a reference asset, but its price can deviate. If a stablecoin trades at US$0.98 when the recipient sells it, the 2% deviation becomes an additional cost outside the network fee.

Issuer and Reserve Risk

A stablecoin’s ability to maintain its value depends on the structure of its reserves, redemption rights, the issuer’s operations, custodians, and market liquidity. The term “stablecoin” does not guarantee that the price will remain stable under all conditions.

Wrong Address or Network Risk

A confirmed blockchain transfer generally cannot be reversed unilaterally. A mistyped address, unsupported network, or missing memo can prevent the funds from being credited.

When using a new address, users may consider sending a small test amount first. The address and network should also be verified through a separate communication channel, particularly when transfer instructions are received through a message that could be compromised.

Smart Contract and Bridge Risk

If the route requires a bridge to move assets between networks, the user adds exposure to smart contract, bridge liquidity, validator, relayer, and wrapped-asset risks. A network with low gas fees may not be the cheapest option if reaching it requires an additional bridge transaction.

Liquidity Risk

The price displayed on the screen may only apply to a small quantity. When an order is larger than the liquidity available, slippage can reduce the recipient’s average selling price.

Compliance and Freezing Risk

A service provider may request additional identity verification, source-of-funds evidence, or an explanation of the transaction’s purpose. Some stablecoin contracts also give issuers the technical ability to freeze addresses under their policies or legal processes. The consequences depend on the token and the parties involved.

Fraud Risk

Scammers may replace the destination address, send a fake wallet link, impersonate customer support, or request a transfer under the pretext of verification. The speed and finality of a blockchain transaction reduce the time available to stop an error after the assets have been sent.

When Can Stablecoins Be More Efficient?

A stablecoin route is more likely to provide an advantage when:

• the sender already owns the stablecoins and does not need another on-ramp;

• the recipient also needs stablecoins and does not have to convert them immediately;

• both parties use the same network;

• the withdrawal and network fees are low;

• liquidity is sufficient on both sides;

• the purchase and sale spreads are narrow;

• the cash-out route is permitted, transparent, and verifiable;

• the amount is large enough to absorb fixed fees;

• the sender and recipient understand wallet security.

The largest savings usually appear when unnecessary stages can be removed. If the sender already holds stablecoins and the recipient intends to use them within the digital-asset ecosystem, the purchase and cash-out costs may not appear immediately.

Those costs may not disappear entirely. They may simply be postponed until the recipient eventually needs rupiah.

When Can a Conventional Transfer Be More Practical?

A regulated conventional route may be more suitable when:

• the recipient needs rupiah directly in a bank account;

• the provider displays the exchange rate and expected payout clearly;

• the total cost is competitive;

• the sender or recipient is unfamiliar with wallets and networks;

• consumer protection and a complaint process are priorities;

• converting stablecoins at the destination is expensive or difficult;

• the transaction requires formal payment documentation;

• the parties cannot tolerate the risk of an irreversible address error.

A slightly higher fee can still provide value if the service offers exchange-rate certainty, a delivery estimate, customer support, and a way to trace or dispute a transaction. The comparison should include cost, time, risk, and certainty rather than isolating the smallest visible fee.

Checklist Before Sending Stablecoins Across Borders

Before making a transfer, record the following figures for both routes being compared:

• the total amount paid by the sender;

• the amount of stablecoins actually obtained;

• the purchase spread;

• the trading fee;

• the asset withdrawal fee;

• the network being used;

• the gas fee;

• the estimated total processing time;

• the stablecoin’s price against rupiah;

• the selling spread;

• the rupiah payout fee;

• the net rupiah received;

• the regulatory status of the parties handling conversion and payout;

• the procedure if the transaction is delayed or sent incorrectly.

A simple calculation can be used:

Effective total cost = Starting amount minus the final usable value received

Effective cost percentage = Effective total cost divided by the starting amount × 100%

If the recipient ultimately needs rupiah, the final value should be based on the net rupiah that is already available for use, not on stablecoins that remain in a wallet.

Are Stablecoins Really Cheaper for Cross-Border Transfers?

Stablecoins can reduce the time and expense associated with the blockchain portion of a transfer. That advantage is meaningful when the network is inexpensive, the assets are already available, liquidity is sufficient, and the recipient has an efficient cash-out route.

A low gas fee does not prove that the entire transfer is cheaper. The largest cost may appear before the assets enter the blockchain or after they reach the destination. Purchase spreads, withdrawal fees, off-ramp pricing, slippage, and payout charges can eliminate the savings generated by the network.

The practical method is to compare the same starting amount across both routes, record every cost, and check how much rupiah the recipient can use and when it becomes available. World Bank data can serve as a historical benchmark, while the stablecoin calculation must use the actual prices and fees displayed at the time of the transaction.

Stablecoins are not automatically cheaper or more expensive. The result depends on the entire route, particularly the on-ramp and off-ramp. Until both stages are included, a claim that stablecoins offer cheap international transfers remains incomplete.
