The NSA monitors banks and credit card transactions

The NSA monitors banks and credit card transactions -- sometimes in apparent violation of national laws and global regulations. The European SWIFT financial transaction network is being tapped on different levels, internal documents from the US spy agency show.

In the summer of 2010, a Middle Eastern businessman wanted to transfer a large sum of money from one country in the region to another. He wanted to send at least $50,000 (€37,500), and he had a very clear idea of how it should be done. The transaction could not be conducted via the United States, and the name of his bank would have to be kept secret -- those were his conditions.

Though the transfer was carried out precisely according to his instructions, it did not go unobserved. The transaction is listed in classified documents compiled by the US intelligence agency NSA that SPIEGEL has seen and that deal with the activities of the United States in the international financial sector. The documents show how comprehensively and effectively the intelligence agency can track global flows of money and store the information in a powerful database developed for this purpose.

"Follow the Money" is the name of the NSA branch that handles these matters. The name is reminiscent of the famous catchphrase by former FBI Associate Director Mark Felt, the whistleblower known as "Deep Throat" who offered the information to Bob Woodward and Carl Bernstein, the Washington Post reporters investigating the Watergate scandal in 1972. Read more >>
