Founder Profile
NMB Postbank Groep
Last reviewed: September 2026 · By Swet Parvadiya
Background
NMB Postbank Groep held an incredibly deep, massively historic background in advanced consumer banking and national postal savings systems. Tracing its absolute origins back to the 1881 Rijkspostspaarbank, this intensely rigorous foundation in mass-market retail finance provided the exact institutional infrastructure required to successfully architect the massive banking arm of the ING Group.
Founding Story
NMB Postbank Groep was a highly powerful Dutch banking conglomerate and the incredibly strategic corporate co-founder fundamentally responsible for providing the massive retail banking infrastructure of the modern ING Group. Operating as a newly consolidated entity formed by the 1989 merger of NMB Bank and the massively historic national postal savings bank (Postbank), the institution aggressively dominated the Dutch consumer finance market. Recognizing the incredible strategic necessity for massive institutional scale, the conglomerate relentlessly negotiated an absolute blockbuster merger with the insurance titan Nationale-Nederlanden in 1991. By fiercely combining its incredibly vast retail deposit base with NN's massive insurance portfolio, the institution completely drove the foundation of ING, permanently cementing the new enterprise as an absolute global juggernaut in comprehensive financial services.
