The secondary circuit of capital is the sphere of commodity circulation, exchange, and consumption. It is a major theme in urban studies because it highlights the structural economic dynamics of capitalist urbanization, especially the role of real estate bubbles and financial crises. The primary/secondary circuit distinction between productive and unproductive labor has also meant this framing is highly relevant to Marxist feminist debates. Recently, there has been a resurgence of interest in the secondary circuit of capital as scholars use it as a framework to cast insight on the role of distributional struggles in contemporary political economic issues.
