Investment in tangible goods
Companies that invest in stamps, works of art, antiques, etc., are not registered financial institutions (like banks, securities or insurance firms). They are therefore not on the official registers of the corresponding Spanish supervisory authorities (the Banco de España, National Securities Market Commission (CNMV) or the Directorate-General for Insurance and Pension Funds (DGS), nor are they subject to the oversight or the sanctioning power of these authorities. This also means they are not subject to any type of supervision over their solvency and operational transparency. You may be interested in consulting Law 43/2007 of 13 December 2007 on consumer protection when purchasing assets with a price-reimbursement offer (in Spanish)Abre en ventana nueva, in relation to consumer protection when purchasing items when a guaranteed repurchase price has been offered.
Additionally, any funds or goods entrusted to such companies by private individuals are not protected by any compensation system, in contrast to the situation of funds or securities entrusted to banking, security and insurance institutions.
