"We have no indications that the TFTP Agreement has been violated, but we are still waiting for additional written assurances that the commission has requested from the U.S.," EU Home Affairs Commissioner Cecilia Malmstrom said.
But EU lawmakers from the center-left parties argued the agreement must be suspended until the U.S. brings credible proof to rebut the allegations.
"The reports of the NSA tapping into the SWIFT data mean that there are now serious doubts that this agreement offers any real legal guarantees and safeguards for EU citizens' personal data," European Socialists and Democrats lawmaker Claude Moraes said. "After several weeks, the U.S. has still not denied these reports or provided sound and irrefutable evidence."
A precursor to the current TFTP agreement was launched by the U.S. Treasury shortly after the Sept. 11 attacks.
In 2010, the European Parliament initially rejected a permanent agreement, but eventually backed it after obtaining a stronger protection of EU citizens' data.
Under the agreement, a European security authority, Europol, assesses whether the data requested by the U.S. are necessary for the fight against terrorism, according to the European Commission. Europol also verifies that each request be tailored as narrowly as possible.
Reports based on material leaked by Snowden, however, alleged that U.S. intelligence services hacked SWIFT's computers to soak up even more data without having to seek prior consent of EU authorities.
The Society for Worldwide Interbank Financial Telecommunication, a private entity, declined to comment specifically on the resolution.
"The TFTP agreement is a piece of EU and U.S. legislation; it is for legislators to make legislative determinations, not private actors. As a private actor operating globally, we need legal certainty and should not be caught between conflicting requirements," it said in an email to the AP.
