The debit card interchange rule, formally known as Regulation II and often referred to as the Durbin Amendment, is a federal regulation designed to cap the fees banks (issuers) can charge merchants for processing electronic debit card transactions. Its primary purpose is to lower transaction costs for merchants and promote competition in the payment processing industry.
Understanding Regulation II (The Durbin Amendment)
Enacted as part of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, Regulation II establishes a maximum interchange fee that can be received by financial institutions (known as "covered issuers") for debit card transactions. This rule aims to bring down the cost of accepting debit cards, which was a significant expense for many businesses.
Components of the Interchange Fee Cap
For any electronic debit transaction, a covered issuer may not receive an interchange fee that exceeds a specific formula. This formula consists of three main parts:
- Base Fee: A fixed amount per transaction.
- Ad Valorem Fee: A percentage of the transaction's value.
- Fraud-Prevention Adjustment: An additional amount allowed if the issuer meets specific fraud prevention standards.
Here's a breakdown of the current cap as stipulated by the rule:
| Component | Amount/Calculation | Notes |
|---|---|---|
| Base Fee | $0.21 | A flat fee per transaction. |
| Ad Valorem Fee | 0.05% (0.0005) multiplied by transaction value | A percentage of the total transaction amount. |
| Fraud-Prevention Adjustment | Up to $0.01 | Eligible if the issuer implements specific fraud prevention measures. |
Example:
For a $100 electronic debit card transaction, an eligible covered issuer's maximum interchange fee would be calculated as:
- $0.21 (Base Fee)
-
- $0.05 (0.05% of $100)
-
- $0.01 (Fraud-Prevention Adjustment, if eligible)
- Total Maximum Fee: $0.27
This means that for a $100 debit transaction, the issuer can receive no more than 27 cents in interchange fees from the merchant's bank.
Who is Subject to the Rule? (Covered Issuers)
The debit card interchange fee cap specifically applies to "covered issuers." These are financial institutions with assets of $10 billion or more.
- Covered Issuers: Banks and credit unions with assets equal to or exceeding $10 billion must comply with the interchange fee cap. They receive the capped rates.
- Non-Covered Issuers: Smaller financial institutions (those with less than $10 billion in assets) are exempt from the fee cap. This allows them to receive higher interchange fees, which can help support their debit card programs and other services.
Why Was This Rule Implemented?
The primary motivations behind the Durbin Amendment were:
- Reduce Merchant Costs: Merchants argued that interchange fees, especially on debit cards, were excessive and added significantly to their operating expenses. The rule aimed to lower these costs.
- Promote Competition: By capping fees, the regulation intended to create a more level playing field among payment networks and financial institutions.
- Transparency: It sought to bring more transparency to the complex world of payment processing fees.

Impact and Implications
The implementation of the debit card interchange rule has had significant impacts across the payment ecosystem:
- For Merchants:
- Lower Processing Costs: Many merchants, especially larger ones, have seen a reduction in the fees they pay for debit card transactions. This can lead to increased profit margins or the ability to offer more competitive pricing.
- For Issuers (Banks):
- Reduced Revenue: Covered issuers experienced a substantial decrease in interchange fee revenue from debit card transactions.
- Changes in Debit Card Programs: Some banks adjusted their debit card programs by:
- Reducing or eliminating debit card reward programs.
- Introducing new fees for certain debit card services or accounts.
- Focusing more on fee income from other sources.
- For Consumers:
- Indirect Benefits: Consumers may indirectly benefit from lower merchant costs if businesses pass on savings through lower prices.
- Fewer Debit Card Perks: Some consumers have experienced a reduction in debit card rewards or benefits previously offered by larger banks.
- Increased Use of Debit: Lower merchant costs can make it more attractive for businesses to accept debit cards.
The debit card interchange rule remains a critical piece of regulation shaping the dynamics of electronic payments in the United States.
