	In economics, leakage is the non-consumption uses of income, including saving, taxes, and imports. In the Keynesian injection-leakage or ] model, leakages are combined with injections to identify equilibrium aggregate output. The model is best viewed as a circular flow between national income, output, consumption, and factor payments. Savings, taxes, and imports are "leaked" out of the main flow, reducing the money available in the rest of the economy.<ref></ref>

Therefore, in credit creation, cash leakage refers to the sums of money borrowed from banks but were not re-deposited. Cash leakage, in this case, lowers the ability of credit creation.<ref>Ngai, J. et al, ''Economics and You 5'', Manhattan, Hong Kong, 2005.</ref>
