In Paris, the Banque de France was created in 1800, just 14 years after the creation of Banque Hottinguer. With a Board of 20 members, Jean-Conrad was appointed Regent in 1803 and for the next 133 years there was a Hottinger family member on the Board of this de facto Central Bank.
As he also held the position of President of the Paris Chamber of Commerce and Industry, Jean-Conrad held a supremely powerful position within the local economy.
