The paper identifies the essence of credit rationing through the prism of its most important endogenous and exogenous prerequisites, assuming the lack of adequate instruments that could be used by banks to individually select borrowers (the so-called screening devices) in conditions of their heterogeneous risk-related breakdown. The paper points out the scope of idiosyncratic attributes of the credit market which prevent it from achieving a state of Walrasian equilibrium, which leads to petrification of credit market imperfections (credit market failure).
