Zur Wirksamkeit von Finanzsanktionen als Instrument im Kampf gegen den Terrorismus

Listed author(s):
  • Michael Brzoska

Already before September 11, 2001, financial measures were used as instruments of counterterrorism. After that, they were seen, at least for some time, as particularly effective in limiting the activities of transnational terrorist groups. Unfortunately, there is little well-grounded research on the effectiveness of financial sanctions, including the freezing of financial assets and the increase on transparency of international financial transactions. A main reason is the lack of reliable data, another are the fundamental problems of investigating the causal links of limited policy measures. This contribution begins with a brief assessment of the implementation of major common measures against terrorist financing (freezing of assets, increased transparency over financial transactions, worldwide acceptance of measures). In the following sections, the available information and data of terrorist incidences is analyzed. Effect of financial sanctions can be demonstrated. However, the data also indicates substitution effects. Furthermore, the efficiency of demonstrable direct effects of financial sanctions is called into question by high indirect costs of unintentional effects. Bereits vor dem 11. September 2001 wurde damit begonnen, Finanzmittel als Instrument im Kampf gegen den Terrorismus einzusetzen. Danach wurden sie zumindest zeitweilig als besonders effektiv angesehen, um den Aktionsradius transnationaler terroristischer Gruppen einzuschränken. Allerdings gibt es wenig fundierte Untersuchungen der Wirksamkeit der gegen den Terrorismus eingesetzten Instrumente wie das Einfrieren von Aktiva und die Erhöhung der Transparenz internationaler Finanztransaktionen. Ein wesentlicher Grund dafür sind der Mangel an belastbaren Daten, ein anderer die grundsätzlichen Probleme der Untersuchung der kausalen Wirkung von begrenzten Politikmaßnahmen. In diesem Beitrag wird zunächst, als Grundlage für intendierte Wirkungen, die Umsetzung von Maßnahmen gegen Terrorfinanzierung (Einfrieren von Finanzaktiva, Erhöhung der Transparenz, weltweite Umsetzung der Maßnahmen) betrachtet. Danach werden vorliegende Informationen und Daten über terroristische Anschläge auf Hinweise auf die Wirkung von Finanzsanktionen, einschließlich von Substitutionseffekten, untersucht. Die belegbare Effektivität von Finanzsanktionen wird allerdings durch hohe indirekte Kosten nichtintendierter Nebenwirkungen hingegen relativiert.
