Stockholms Banco joutui setelirahoituksen vuoksi talousvaikeuksiin, ja Johan Palmstruch tuomittiin holtittomasta talouden- ja kirjanpidosta vankeuteen ja maanpakoon 1668. Samalla hän menetti liiketoimintaoikeutensa ja arvonimensä.

[...] His guilt lay in two matters: Irresponsible book-keeping and control, and some shortage of cash on account of miscalculation and book-keeping omissions."
