The purpose of this study is to design a model based on game theory involving three economic actors: the government, the central bank, and the speculator. In this paper, we aim to minimize the influence of the speculator on the economy. The government aims to achieve maximum economic growth by implementing financial policies. Meanwhile, the central bank focuses on maintaining price stability through its monetary policies. Additionally, speculators look to generate the highest profits by actively intervening in the currency market. To achieve this, we will analyze the Nash equilibrium and the unilateral support equilibria in the game using a modified logistic function. In the Nash equilibrium, each player individually trying to maximize their own benefit. In contrast, in the unilateral support equilibria, each player seeks to maximize the profit (or minimize the loss) of the player they are supporting. The design of this game has been analyzed in six scenarios. The results indicate that in the first and fifth scenarios—specifically, the main game and the scenario where the government supports the central bank while the central bank also supports the government—the intervention of the speculator in the economy reaches its lowest possible level. In this case, unilateral support equilibria involve the government and the central bank adopting contractionary fiscal and monetary policies to achieve their lowest losses.
