Political decisions over economic growth policies influence the degree of bureaucratic autonomy and regulatory governance dynamics. Yet, our understanding of these processes in the Global South is somewhat limited. The article studies the post‐Global Financial Crisis period and relies on elite interviews and secondary sources from Turkey. It problematizes how an economic growth model dependent on foreign capital inflows, which are contingent on global financial cycles, influences the trajectory of bureaucratic autonomy. Specifically, we argue that dependence on foreign capital flows for economic growth creates an unstable macroeconomic policy environment: while the expansionary episode of the global financial cycle masks conflicts between the incumbent and bureaucracy, the contractionary episode threatens the political survival of the incumbent. In the case of Turkey, this has incentivized the ruling coalition to resort to executive aggrandizement to control monetary policy and banking regulation, which resulted in a dramatic decay of the autonomy of the regulatory agencies since 2013.
