Following the fall of the authoritarian president Zine el-Abidine Ben Ali, the poor health of the three major state banks has come to light. Because the three big state banks (Société Tunisienne de Banque, Banque de l'Habitat, and Banque Nationale Agricole) make up about 40% of total banking assets in the country, they are structurally important for the economy. As Tunisia's tourism sector has suffered following the 2011 revolution and the 2015 terrorist attack in Sousse, the state banks' financial health has deteriorated, since approximately 40% of their bad debts come from the tourism industry.
