50% rule in sanctions screening and when a counterparty counts as listed
What the EM System and Inter Rao Lietuva judgments and OFSI's Citibank penalty mean for counterparty checks under EU, UK and US rules






Whether an unlisted company is caught by the asset freeze applicable to its shareholder was tested twice in 2026. In EM System, a case under the Belarus regime, the Court of Justice confirmed a rebuttable control presumption at exactly 50%. In Inter Rao Lietuva, it required objective and sufficiently solid evidence where control is alleged without a sufficient ownership basis. OFSI's £4.7 million Citibank penalty shows the operational cost of freezing too late. This article explains what those developments mean for counterparty screening, how the UK and US rules differ from the EU framework, and what the file should contain.
