The Fonds de Garantie des Dépôts et de Résolution (FGDR), created by law in 1999, protects clients when a banking institution fails. The Deposit Guarantee compensates depositors for an amount up to €100,000 per person, per institution. The Investors Guarantee compensates up to €70 000 per person, per institution, for securities (stocks, bonds, ). The FGDR can also intervene on a Resolution basis, before the institution fails.
