This thesis started from the question asking who is the big player of the North Korean private banking system and how did they accumulate cash while it is virtually impossible for a common North Korean to accumulate huge sum of money through commerce due to the regime s constant control and oppression. This thesis has two purposes, namely: explaining the dynamics behind the North Korean private banking system structure based on concepts such as centrality of regime fund, inflow of outside cash and food chain relationship among power-based donjus(officers), market-based donjus and citizens; and analyzing the effect of private banking system development to the stability of North Korean regime. Currently, economic resources of North Korea are concentrated at the topmost portion of the power structure, and the function that brings down the resources to the bottom, I.e., the distribution carried out in the name of the Leader, has vecause continued economic crisis has made the WPK to set an economic objective that secures the survival of the executives instead of securing the livelihood of the citizens. The regime has untentionally formalized a group of parasitic rogues as acquiring power has become more difficult through this economic policy. The spread of the market mechanism has been expanded to the whole market beyond the regular consumption activity, from national economy to banks and regime fund of the top executive. This phenomenon has created the pyramidal structure of the North Korean private banking system. This was the result of disallowing and oppressing the accumulation of private property through monopolistic capitalism of the ruler, graft and corruption of regime officials and embracing market as a management area of the firm. Since the adhesion between the market and the power has transformed itself into a symbiosis, a coexistence and a close relationship between the two, it integrates the market economy mechanism and structure and flow of the private banking system. As the social relationship is reorganized based on the market logic, the officers and citizens build new moral sense followed by increase in material value, and they strengthen the food chain structure as they become colluded with each other. This process then promotes the flow of private banking system. In the perspective of the KJU regime, which considers regime survival as the foremost objective, the economic policy of WPK securing the regime fund will be continued and reinforced. In addition, the private fund will progressively become larger as national elites and officers plunder the regime fund, and as regime fund depletes the instability of the regime will be increased. The market activities of North Korean citizins under the banner of self-rehabilitation is expected to vitalize the private banking system with the learning effect regarding capitalistic market economy concepts such as demand and supply, competition, logistics, accumulation of wealth and liberty.
