The history of Nationale Borg

Nationale Borg was founded in Amsterdam in 1893 by J. Nienhuys, a successful businessman, who had been the first in Amsterdam to have his residence lit by electricity.
The company provided bonds that guaranteed the honesty of civil servants in the exercise of their duties and performance bonds issued to a railway company, the IJzeren Hollandsche Spoorweg Maatschappij, that was laying new track. This laid the foundation for Nationale Borg’s surety bond businesses.
Over the years Nationale Borg grew substantially. In 1923 it moved to its current premises on the Keizersgracht canal. Starting in 1946, Nationale Borg began its reinsurance business that was to amount for a steadily growing share of the total.
As from its incorporation Nationale Borg was quoted on the stock exchange. As time went by a substantial proportion of the shares fell into the hands of major banks and insurers.  In 1991 the company was acquired by Nationale-Nederlanden, as a result of which it soon became part of what is now ING Group.
The nineties saw further expansion of its leading position in the Dutch guarantees market leading to a balance between its reinsurance business and the company’s direct Dutch insurance activities. That success led to expansion into Belgium around the turn of the century where Nationale Borg has now become market leader as well.
In 2007 the company regained its independence when ING transferred its shares to two investment companies, HAL Investments and Egeria. The purpose is to further extend its leading position in the surety bond market.
