The widespread use of U.S. currency abroad, together with the outdated security features of the currency, makes it a particularly vulnerable target for international counterfeiters. According to the Federal Reserve, the proportion of U.S. currency in circulation abroad has increased from 40 percent in 1970 to over 60 percent today. High foreign inflation rates and the relative stability of the dollar have contributed to the increasing use of U.S. currency outside the United States. And, in fact, the United States benefits from this international use. When U.S. currency remains in circulation, it essentially represents an interest-free loan to the U.S. government. The Federal Reserve has estimated that the U.S. currency held abroad reduces the need for the government to borrow by approximately $10 billion a year. Despite this benefit, its increasing international use has made U.S. currency a target for counterfeiting. Furthermore, with the exception of two changes introduced in 1990, the security features of the currency have not substantially changed since 1929, which has resulted in the U.S. dollar’s becoming increasingly vulnerable to counterfeiting. (See fig. 1 for the existing security features of the currency.) Congressional groups and the media have continued to highlight their concerns that the counterfeiting of U.S. currency abroad is becoming an increasingly serious problem. Concerns about counterfeiting abroad were heightened in 1992 with the issuance of the first of two reports by the House Republican Research Committee’s Task Force on Terrorism and Unconventional Warfare. These reports charged that a foreign government was producing a very high-quality counterfeit note, commonly referred to as the Superdollar, to support terrorist activities. In 1993, the House Appropriation Committee’s Surveys and Investigations staff completed a report on the Secret Service’s counterfeiting deterrence efforts and briefed the House Appropriations Committee. In the same year, a bill—the International Counterfeiting Deterrence Act—was introduced to address international counterfeiting and economic terrorism; however, it was not passed. The Secretary of the Treasury is responsible for issuing and protecting U.S. currency. Treasury, including the Secret Service and the Bureau of Engraving and Printing, and the Federal Reserve have primary responsibilities for combating the counterfeiting of U.S. currency. The Secret Service conducts investigations of counterfeiting activities and provides counterfeit-detection training. The Bureau of Engraving and Printing designs and prints U.S. currency, which includes the incorporation of security features into the currency. The Federal Reserve’s role is to distribute and ensure the physical integrity of U.S. currency. It receives currency from financial institutions around the world and uses specialized counting and verification machines to substantiate the authenticity of all U.S. currency received. The various counterfeiting deterrence efforts are coordinated through the Advanced Counterfeit Deterrence Steering Committee, which was formed in 1982. The Secret Service is the U.S. agency responsible for anticounterfeiting efforts abroad. At the time of our work, the Secret Service primarily used its six overseas offices, three task forces, two temporary operations, and resources from six domestic offices to conduct this task. (See app. I for a description of Secret Service offices responsible for locations abroad.) Secret Service offices outside the United States typically are staffed by one to six agents. Agents working abroad are involved in the same issues as their domestic counterparts, such as detecting counterfeits, investigating financial crimes, and protecting dignitaries. However, the majority of a typical agent’s time abroad is spent on counterfeiting deterrence efforts. In pursuing these efforts, agents must rely on the cooperation of foreign law enforcement agencies and sometimes are allowed to provide only investigative support. This situation is different from that in the United States, where agents have direct investigative authority. The Secret Service also provides other staff to support international counterfeiting deterrence activities. For example, the Secret Service has assigned two Counterfeit Division staff to work with the Four Nations Group and three agents to work with Interpol—the International Criminal Police Organization. To obtain information on the nature and extent of counterfeiting of U.S. currency abroad, as well as U.S. efforts to combat this activity, we obtained views and material from (1) U.S. government agencies in the United States and abroad; (2) foreign law enforcement and financial organization officials in seven European countries, as referred to us by U.S. embassy officials; (3) Interpol officials in the United States and abroad; and (4) individuals researching the Superdollar case, including the author of the House Republican Task Force on Terrorism and Unconventional Warfare reports on the Superdollar. We performed our review in the United States, England, France, Italy, Germany, Hungary, Poland, and Switzerland. Interpol, State Department, and Secret Service officials recommended these countries for our review on the basis of their knowledge of counterfeiting abroad. To obtain U.S. government perspectives on the nature and extent of counterfeiting as well as on efforts to deter this activity, we interviewed and obtained documentation from senior Treasury officials in Washington, D.C.; Secret Service officials in Washington, D.C.; New York, New York; San Francisco, California; England; France; Italy; and Germany; and Bureau of Engraving and Printing officials in Washington, D.C. We also interviewed Federal Reserve Board officials in Washington, D.C.; Federal Reserve Bank officials in San Francisco and New York; and State Department officials in Washington, D.C., and abroad. To secure information on the extent of the problem of counterfeit U.S. currency abroad, we obtained Secret Service data on domestic and international counterfeit detections. We then reviewed the Secret Service’s counterfeit-detection data for fiscal year 1987 through fiscal year 1994. We also reviewed Interpol’s 1991 to 1993 annual reports on international counterfeiting activity. We did not independently verify the accuracy of the data that the Secret Service and Interpol provided. To gain perspective on both counterfeiting and deterrence efforts abroad, we obtained input from foreign law enforcement and financial organization officials in the countries we visited. (See app. II for a listing of foreign agencies and organizations we contacted while abroad.) In conducting our interviews, we did not pose the same questions to all officials. Thus, the responses we obtained cannot be generalized. The scope of our work was limited by a number of factors related to national security and investigative concerns. First, due to the criminal nature of counterfeiting, the actual extent of counterfeiting abroad cannot be determined. Second, since current known counterfeiting activities involved ongoing investigations, we were not able to fully explore and discuss these investigations with law enforcement and intelligence officials. Third, due to the sensitive nature of the ongoing investigation of the so-called Superdollar, we were unable to fully explore this extremely high-quality, allegedly foreign government-sponsored, counterfeiting operation. As a result of these limitations, this report is not evaluative, and it thus contains no conclusions or recommendations. This report was prepared using unclassified sources of information. The draft report underwent a security classification review by the appropriate agencies, including Treasury and the Secret Service, and was released as an unclassified report. Although they initially stated that some of the information was or should have been classified, Treasury and the Secret Service later rescinded this statement after they performed a full security classification review and we reached agreement with them on a minor revision to appendix VII. (See app. VIII, pages 66 and 67, for Treasury and Secret Service statements that the report is unclassified.) We conducted our review from September 1994 to May 1995 in accordance with generally accepted government auditing standards. In June and then again in November 1995, we updated our work on Secret Service staffing abroad. We obtained written agency comments on a draft of this report from the Departments of the Treasury and State and from the Federal Reserve. These comments are discussed at the end of this report and presented in appendixes VIII through X. The nature of counterfeiting of U.S. currency abroad is diverse, including various types of perpetrators, uses, and methods. The relative sophistication of the counterfeiter and method used results in counterfeit notes of differing quality. According to a National Research Council report requested by Treasury, the counterfeiting problem will increase as technologies improve and are made more accessible to the public. Already, the Secret Service has been troubled by some very high-quality counterfeits of U.S. currency identified as originating abroad. Perpetrators include both the casual and the professional counterfeiter. The casual counterfeiter is a person who commits the crime because it is convenient or easy to do. For example, an office worker may use a copying machine to counterfeit U.S. currency. The number of casual counterfeiters is expected to increase with the greater accessibility of and improvements to modern photographic and printing devices, according to the National Research Council report. Conversely, the professional counterfeiter may be a member of a gang, criminal organization, or terrorist group. Foreign law enforcement and Secret Service officials that we interviewed told us of suspected links between counterfeiting and organized crime. Counterfeit U.S. currency is used for economic gain and is sometimes linked to other crimes. According to foreign law enforcement and Secret Service officials, counterfeit U.S. currency is sometimes distributed in conjunction with drug trafficking, illicit arms deals, and other criminal and/or terrorist activities. Moreover, Secret Service and foreign law enforcement officials told us that counterfeit U.S. currency is now sometimes produced by counterfeiters in one country for export to another country. For example, in Milan, Italy, counterfeiting has become an industry in which counterfeit U.S. currency is produced for export, according to Italian law enforcement officials.
