This paper offers an understanding of the core drivers of the political economy of the ruling Communist Party in Vietnam. In the absence of political reform, the regime does not possess the powers required by the new conditions of a market economy and an increasingly open society. Designed for Soviet totalitarianism, and without popular support or authority, the formal political institutions are anachronistic and thus limit the range of powers available to the Party. As the regime is thus unable to reliably deploy policy unless it feels threatened, politics becomes a competition over spoils. Thus, if macroeconomic instability actually or potentially threatens the regime, the Politburo gains authority to act, and policy is deployed. Yet, as popular discontent mounts over corruption, favourable treatment of politically connected businesses, public education and health, and other areas not seen as regime‐threatening, the disequilibrium leads to use of the security forces and increasing violence against popular opposition.
