MasterCard Europe to Reduce
Debit-Card Fees Amid EU Probe

BRUSSELS -- MasterCard Europe said it would lower bank fees related to debit-card transactions by 60%, a cut that could ease pressure on the company from European Union regulators to reduce card costs to retailers.

The European Commission said in a statement that it would "examine in depth the new interchange-fee scheme."

MasterCard Europe said its new fee structure would take effect in January 2008. The new fee for a €50, or about $67, transaction paid with a Maestro debit card would be between nine European cents and 20 European cents (12 cents to 27 cents), down from the current 25 European cents to 59 European cents, it said.

The new fee structure doesn't apply to MasterCard credit cards.

The European Commission said in 2003 and again in June that MasterCard was restricting cross-border competition among banks by setting the fees. MasterCard benefits by setting them because it can use the tool to provide incentives to banks to promote the use of its cards.
