NEW YORK (

TheStreet

) --

Federal Reserve

Chairman Ben Bernanke said that new rules clamping down on interchange fees will not be in place by an April 21 deadline, according to a

Reuters

report that cites a letter sent to Congress Tuesday.

Shares of

Visa

(V) - Get Report

were up 4% in early trading to $74.95.

MasterCard

(MA) - Get Report

was also up 4%, changing hands at $261.09.

The new rules will implement the Durbin Amendment of the Dodd-Frank Wall Street Reform and Consumer Protection Act, signed into law by President Obama last July.

Since the Fed in December first proposed a maximum interchange fee of 12 cents per transaction, there has been a groundswell of negative reaction, including a lawsuit by

TCF Financial

(TCB)

, which is supported by industry groups including America's Community Bankers, and over 11,000 comment letters received by the Fed.

Bernanke said the Federal Reserve needs the extra time to study the comment letters, but is committed to having a finalized rule by July 21.

TCF Financial said in its annual report that the "reduction in TCF's average interchange rate after July 21, 2011 could approach 85%," if the new rules as originally proposed by the Federal Reserve became permanent.

Bank of America

(BAC) - Get Report

has said the limit on interchange fees could cost the company $2.3 billion in annual revenue.

The Durbin Amendment's fee limitation applies to banks with over $10 billion in total assets. According to a March 25 report from Mat O'Connor of

Deutsche Bank

(DB) - Get Report

, large banks with interchange fees contributing a large percentage estimated of earnings per share for 2011 include TCF Financial, with 25% of estimated EPS coming from interchange fees;

Regions Financial

(RF) - Get Report

with interchange fees contributing 23% of estimated earnings;

SunTrust

(STI) - Get Report

, with 13% of estimated earnings derived from interchange fees; and Bank of America and

M&T Bank Corp.

(MTB) - Get Report

, with 11% apiece.
