Understanding Interchange Fees: How Stablecoins and OTC Desks Help Payment Processors Lower Costs

Interchange fees represent one of the most significant expenses for payment processors, cutting into their margins and increasing transaction costs for merchants. These fees, charged by credit card companies and issuing banks, are applied to every card transaction, including credit and debit card payments, and are determined by credit card payment networks. Payment processors must find ways to optimize costs while maintaining efficiency, especially when dealing with cross-border transactions and large transaction volumes.

One solution gaining traction is the use of stablecoins and OTC desks to reduce dependence on traditional payment networks and bypass costly interchange fees. By leveraging crypto liquidity and blockchain-based payment solutions, payment processors can offer more cost-effective alternatives to traditional card-based payment models.

This article explores how stablecoins and OTC trading desks can help payment processors lower interchange fees, improve liquidity, and streamline cross-border payment processing.

Understanding Interchange Fees and Their Impact on Payment Processors and Credit Card Companies

What Are Interchange Fees?

Interchange fees are charges that a merchant pays to issuing banks whenever a credit card or debit card transaction is processed. These fees cover the risk, processing, and fraud prevention costs associated with electronic payments. The card networks (such as Visa, Mastercard, and American Express) set interchange rates, which vary depending on factors such as:

• Card type: Debit cards generally have lower interchange fees than credit cards.

• Transaction type: Card-present transactions have lower fees compared to card-not-present transactions (e.g., online payments).

• Merchant category: Different industries have different merchant category codes (MCCs), which influence the fees merchants pay.

• Transaction size: Larger transactions often come with higher interchange fees.

Breakdown of Interchange Fees and Debit Card Interchange Fees

Interchange fees typically consist of:

1. A fixed rate per transaction – For example, a flat fee of $0.10 per transaction.

2. A percentage of the transaction amount – Usually between 1% and 3%, depending on the issuing bank, credit card payment network, and merchant risk profile.

The average interchange fee varies based on transaction types and the influence of credit card networks and merchant categories.

For payment processors, interchange fees represent a major cost, affecting profitability and pricing for merchants. The challenge is how to reduce these costs while maintaining smooth transaction flows.

Types of Interchange Fees

Interchange fees can be categorized into two main types: credit card interchange fees and debit card interchange fees. Understanding the differences between these fees is crucial for payment processors looking to optimize costs.

Credit Card Interchange Fees

Credit card interchange fees are charged to merchants for processing credit card transactions. These fees are typically higher than debit card interchange fees, ranging from 1.5% to 3.5% of the transaction amount, plus a flat fee. Credit card interchange fees help fund rewards programs, such as cashback, points, and travel miles, offered by credit card companies. These programs incentivize card usage but also contribute to the higher costs merchants pay per transaction.

Debit Card Interchange Fees

Debit card interchange fees, on the other hand, are charged to merchants for processing debit card transactions. These fees are generally lower than credit card interchange fees and are capped at $0.21 plus 5 basis points times the value of the transaction for issuers with consolidated assets of $10 billion or more. Debit card interchange fees cover the costs of processing debit card transactions, including maintaining the debit card network and providing customer service. This makes debit card transactions a more cost-effective option for merchants compared to credit card transactions.

Factors Affecting Interchange Fees

Interchange fees are influenced by various factors, including the type of transaction, the merchant category code, and the card issuing bank. Understanding these factors can help merchants and payment processors better manage and potentially reduce their interchange costs.

Card Not Present Transactions

Card not present transactions, such as online or phone orders, typically incur higher interchange fees than card present transactions. This is because card not present transactions are considered higher risk, as the merchant cannot verify the cardholder’s identity directly. The increased risk of fraud and chargebacks in these transactions justifies the higher interchange fees charged by credit card companies.

Card Present Transactions

Card present transactions, where the cardholder is physically present and the card can be swiped or inserted into a terminal, generally have lower interchange fees. These transactions are considered lower risk because the merchant can verify the cardholder’s identity, reducing the likelihood of fraud.

In addition to the type of transaction, interchange fees are also affected by the merchant category code (MCC). Merchants in higher risk categories, such as travel or entertainment, may face higher interchange fees compared to those in lower risk categories like grocery or retail. The MCC helps card networks assess the risk associated with different types of businesses and adjust fees accordingly.

The card issuing bank also plays a role in determining interchange fees. Different banks may charge varying fees for the same type of transaction. For instance, a credit card issued by a bank with a high rewards program may have a higher interchange fee than one issued by a bank with a lower rewards program. This variability underscores the importance of merchants reviewing their interchange fees to ensure they are being charged appropriately for each transaction.

By understanding these factors, merchants and payment processors can better navigate the complexities of interchange fees and work towards reducing their overall transaction costs.

How Stablecoins Can Lower Interchange Fees

What Are Stablecoins?

Stablecoins are digital assets pegged to fiat currencies, such as USDT, USDC, and DAI. Unlike volatile cryptocurrencies like Bitcoin, stablecoins maintain a stable value, making them ideal for transactions and settlements.

By adopting stablecoins, payment processors can reduce reliance on traditional card networks and lower transaction costs associated with credit and debit card interchange fees. Unlike transactions processed through a credit card company, stablecoin transactions do not incur high interchange fees.

Benefits of Stablecoins for Payment Processors

1. Lower Processing Fees

• • Traditional interchange fees range between 1% and 3%, while stablecoin transactions cost a fraction of that (often less than 0.1% in blockchain network fees). The cost savings are even more significant when considering the volume of transactions processed by payment processors.

2. Eliminating Card Network Fees

• • Payments processed via stablecoins bypass Visa, Mastercard, and traditional acquiring banks, avoiding interchange fees altogether.

3. Faster Settlement Times

• • Traditional card transactions take days to settle, while stablecoin transactions settle in minutes, reducing liquidity constraints.

4. Lower Risk of Chargebacks and Fraud

• • Stablecoin transactions are irreversible, eliminating issues like fraudulent transactions and chargebacks, which cost businesses billions annually.

By leveraging stablecoins for settlements, payment processors can significantly cut costs, improve efficiency, and reduce reliance on expensive credit card processing networks.

The Role of OTC Desks in Crypto Liquidity for Payment Processors

What Is an OTC Desk?

An OTC (Over-the-Counter) trading desk is a platform that allows institutions to trade large amounts of crypto assets, including stablecoins, without using public exchanges. Unlike traditional exchange order books, OTC desks provide:

• Deep liquidity for large transactions

• Better pricing with minimized slippage

• Fast settlements with lower transaction fees

For payment processors, an OTC desk like FinchTrade ensures efficient conversion between stablecoins and fiat currencies, enabling seamless crypto-based transactions.

Why Payment Processors Need OTC Liquidity

1. Lower FX and Conversion Costs

   • OTC desks offer better exchange rates compared to retail exchanges, reducing currency conversion fees for payment processors handling cross-border payments.

2. Scalability for High-Volume Transactions

   • Traditional card payment systems have volume-based fees, while OTC trading allows for bulk transactions at competitive rates.

3. Reduced Counterparty Risk

   • OTC desks provide secure settlement services, mitigating risk exposure compared to traditional banking institutions.

By integrating OTC liquidity solutions, payment processors can optimize stablecoin transactions and reduce costs while maintaining efficient global payment processing.

Comparing Traditional Payment Processing with Stablecoin Transactions and Credit Card Payment Networks

The cost savings and efficiency gains provided by stablecoin payments make them an attractive alternative to traditional payment networks.

Regulatory Considerations for Stablecoin Transactions and Merchant Service Fees

Despite the benefits, regulatory challenges remain when adopting stablecoins for payment processing. Key considerations include:

1. KYC/AML Compliance

• Payment processors must ensure that all transactions comply with KYC (Know Your Customer) and AML (Anti-Money Laundering) regulations. Regulatory changes aimed at lowering merchant service fees can further enhance the benefits of adopting stablecoins.

2. Stablecoin Reserves & Issuers

• Choosing regulated stablecoin issuers (such as USDC from Circle or BUSD from Binance) ensures transparency and financial security.

3. Tax Implications

• Stablecoin transactions may be subject to tax reporting, requiring compliance with local tax authorities.

Partnering with a compliant OTC liquidity provider like FinchTrade helps navigate regulatory challenges while benefiting from the advantages of stablecoin transactions.

How Payment Processors Can Implement Stablecoin Solutions

1. Partner with a Crypto OTC Desk

Payment processors should work with a trusted OTC desk to access deep liquidity for stablecoin transactions. An OTC partner provides:

• Institutional-grade liquidity

• Faster execution with lower fees

• Regulatory compliance support

Unlike credit card payment networks, OTC desks provide direct access to crypto liquidity.

2. Enable Stablecoin Payment Options

Integrating stablecoins into merchant services allows businesses to accept crypto payments while reducing card processing fees.

3. Use Smart Contracts for Automated Settlements

Smart contracts can automate transactions, reducing the need for manual reconciliation and improving operational efficiency.

Automating transactions processed through smart contracts can further reduce operational costs.

4. Educate Merchants and Businesses

Payment processors should educate merchants on the benefits of stablecoins, helping them adopt crypto payments with confidence.
