Does being designated by OFAC automatically trigger EU or UK sanctions?

No. OFAC, EU, and UK sanctions are legally independent regimes. However, significant overlap exists in practice — particularly under coordinated programmes targeting Russia, Belarus, and human rights violators. EU and UK authorities monitor OFAC designations and may impose parallel listings based on shared intelligence or policy alignment. The legal criteria differ: EU sanctions require Council decisions with specific evidentiary standards, while UK designations follow the Sanctions and Anti-Money Laundering Act 2018. A successful OFAC delisting does not automatically result in EU or UK removal. Each jurisdiction requires separate challenge proceedings before its competent authority or court.
