EU cash controls
The EU Council of Ministers on 12 July 2005 adopted a Regulation which aims to introduce an EU-wide approach to controlling cash movements into and out of the EU. The Regulation is applicable in all Member States as of 15 June 2007. It obliges travellers entering or leaving the Community and carrying any sum equal or more than EUR 10,000 (or its equivalent in other currencies or easily convertible assets such as cheques drawn on a third party) to make a declaration to the customs authorities.
