This article explores the link between the history of small-firm associations and the development of Dutch financial infrastructure geared toward small firms. In particular, it tests Verdier’s thesis about the origins of state banking using an in-depth case study of the Dutch small-firm movement. This article shows that Dutch small-firm associations did not simply became politically relevant and use their power to lobby for state banking, but rather used the topic of insufficient access to credit to rally support, mobilize members, and obtain subsidies from the government. During this associational process, they had to navigate local contexts and power structures that, in turn, also shaped the financial system. State banking was initially not demanded by small firms, but arose as the result of failed experiments with subsidized banking infrastructure and a changing position of the government on how to intervene in the economy.
