Theodor Weimer, outlining a series of reforms he was pondering in the aftermath of the country's biggest post-war corporate fraud, said other exchanges around the world are vocal when a company is late in publishing its earnings.
"We will certainly go in the direction of naming and shaming," Weimer told a banking conference.
Weimer said that he urged parliamentarians this week, at a closed-door hearing about the collapsed payment company, to change laws to allow him to be public in stating where he sees problems.
He also said that they would look at increasing sanctions and improving corporate governance rules for membership of Germany's blue-chip DAX index.
