when the term leakage is used in the retail sector it usually refers to consumers who spend money outside their local market this presents a challenge for businesses within this kind of economy in general they must search for other sources of revenue 
another scenario where leakage is relevant is in a model of credit creation that assumes that all loans borrowed from a bank re deposited into the system of course this would never happen in reality but it allows for a simple calculation of the amount of credit that is created in reality cash leakages occur when amounts of money are borrowed from banks but not re deposited leakages also occur in the form of funds deposited in banks but not lent out in this system cash leakage lowers the ability of credit creation in the case of transnational corporations tncs leakage can also occur large companies sometimes have factories or production facilities in other countries and these factories create wealth for the company which is then not transferred to the economy of the host country and instead to that of the corporation involved the economic value of goods and profits lost here is leakage tourism can cause leakage through funds transitioning between those who live in a particular area and chosen tourist destinations additionally tourism based businesses that have facilities in one area but hold headquarters in another can create leakage as funds are shifted to the headquarters location information or data leakage occurs when internal information that should be held private or confidential is released to the public this release of information can include the accidental or intentional disclosure of information or a failure to secure the information which leads to exposure
