The King still can bestow hereditary noble titles but these are seldom given.
Let us review the year 2014:
2014 Baron Paul Buysse (enterpreneur) - bestowed the title of Graaf / Comte, hereditary for his descendants
2014 Willem, Liduine and Monique de Westerholt Gysenberg - incorporation of foreign nobility with the hereditary title of Graaf / Comté
2014 Jonkheer / Écuyer Marc du Bois - bestowed the title of Baron, hereditary for his descendants
2014 Ridder / Chévalier Ernst de Laminne de Bex - bestowed the personal title of Baron
These four examples were not real new elevations as all already belonged to the nobility anyway. A real elevation in 2014:
2014 Herman Daems (Chair of BNP Paribas) - elevated into the nobility with the title of Baron, hereditary for his descendants
What often happens: "elevation into the Belgian hereditary nobility with a personal title". That means that the person him/herself is a Count, Viscount, Baron, whatever but his descendants are without title but belonging to the aristocracy (they can use the predicate Jonkheer/Écuyer if they want). Some examples:
2014 Johan Swinnen (Ambassador) - elevated into the hereditary nobility, the title of Baron is for his person only
2014 Serge Brammertz (Chief Prosecutor at the International Court of Justice in The Hague) - elevated into the hereditary nobility, the title of Baron is for his person only
