Nya Banken, a bank founded in Stockholm in 1912 by financier Olof Aschberg.
Marketed as a workers' bank, it discreetly moved shipments and payments that converted revolutionary assets into ordinary currency.
It acted as a transit point for gold, quietly handling the shipments and payouts that turned seized wealth into usable funds.
It shows the plumbing that lets illicit wealth flow into the normal financial system without leaving obvious fingerprints.
