Petr Kellner no doubt knows his timing is awful. The Czech Republic’s richest man, who controls multiple telecom firms at home and a bank in Russia, Kellner has been feeding China’s consumption habit by giving out small-value unsecured loans for over a decade.

And of all possible IPO venues, Kellner has chosen Hong Kong.
