The Magyar Postatakarékpénztár was pressed into currency issuance during the chaotic interregnum of 1919, when Hungary was cycling through governments — the collapse of the Habsburg state, Mihály Károlyi's short-lived republic, and then Béla Kun's Hungarian Soviet Republic in quick succession. These postal savings notes were emergency instruments, produced domestically in Budapest rather than through the established Austro-Hungarian note-printing apparatus in Vienna, which had ceased to function as a unified institution.

The series circulated under more than one political authority, which complicates any clean attribution to a single issuing regime. Overprinting and revalidation stamps appear on some examples as successive governments attempted to control which paper remained legal tender.
