On 20 August 2025, the US Treasury's Office of Foreign Assets Control imposed sanctions on Guillou as a member of the pre-trial panel that approved and issued arrest warrants against Israeli Prime Minister Netanyahu and former defense minister Gallant.^[8] Guillou’s name was listed among 15,000 people, including Al-Qaeda terrorists, drug cartel members, and Vladimir Putin.^[9] The effect of the sanctions means that Guillou is banned from US territory. Under US law, the sanctions also prohibit any American individual or legal entity, as well as any person or company, including their overseas subsidiaries, from providing services to him. This has had the effect of blacklisting him from the world's banking system.^[10]
