Abstract
Any bank depends heavily on other banks to provide the liquidity it needs in addition to other financial transactions between banks and this represents an interbank market, but this may be a reason to facilitate the transmission of financial crises when they occur. The Greek sovereign debt crisis is a model. Therefore, it is through direct and indirect correlation between banks inside the state and between banks inside and outside the country that led to the crisis affecting other countries in the euro area, including (Italy, Spain, Ireland, Cyprus) which is the research sample that was studied. For the period 2010-2017, using the Pearson correlation model and the legal correlation model, and it was concluded that this correlation in the interbank market helped the spread of the Greek sovereign debt crisis, so it is necessary to set limits for the banks ’transactions among them in such a market.
