The importance of this research stems from the fact that it tries to investigate the nature of relationship between banking activity and the performance of the financial market, in theory and in practice.

Shortly after exploring the existence of this relationship between the folds of the theory concerned in this regard, the research is actively seeking to clarify the truth on the existence of such a relationship in practice.

The research hypothesis confirms that when the spread rate (expands) decreases and the liquidity ratio decreases (increases) in circulation, the performance of the financial market increases (deteriorates).

The research aims to give a brief theoretical brush on the research variables, which are the spread rate, the ratio of bank liquidity, and the performance of the financial market, and then the research investigates the nature of the relationship between them.

As for the time frame of the research, it includes the period from 2000 to 2019, according to the data available from sober sources.

The research tended to adopt the theoretical and analytical approach to obtaining the research outputs.

The research structure revolves around several aspects, the first of which is a theoretical framework on the concepts of spread and liquidity ratio, and how they are calculated in specialized scientific literature, then the research attempts to access the concept of financial market performance, and the research considers the selection of the general index of the financial market, as an accurate indication of the performance of this market, as is being done in most scientific researches.
