This essay will explore the power held by International Financial Institutions (IFIs) and study the policies of the two most important IFIs – the International Monetary Fund (IMF) and the World Bank. Specifically, this essay analyzes the motivation behind these institutions’ interventions in countries of the Global South, assessing to what extent their policies may influence the "most important things" among nations. These policies merit detailed investigation because the projects carried out are world-scale, because they have such a lasting impact upon our world, and because of these things, the controversial, critical discussion on it not just highlights the advantages of the project, but also provides an analysis of some aspects that are substandard in the economic policies of the institutions. The essay thus aims at injecting some insights into the connection between the rules of the international economic system and the difficulties of development. It is said that no one these days can afford to ignore International Financial Institutions (IFIs), which constitute the most influential centers in the international financial system, whose policies and proposals are largely determined by Paris Club officials. To ignore them is to forget, reject, or remain ignorant towards the equivalence of "the most important things that nations may at present under capitalism be involved in when they wish to speak with one another and show one another the ways in which they are, intend to be, and have been as citizens of the country. Just what are these projects? The point in listing them is not to say that everyone who has something to say at the international level should always be in accord, or even bother about what everyone else is doing, but to indicate the type of project which very often will be both permanent and world-scale."
