We develop a theory connecting leverage and volatility in almost the same way as private goods volumes are in dual interconnection with their prices. But the corresponding (substantially dynamical non-linear) theory is technically too complex both for operating and for results understanding, so here we develop a substantially simplified bi-linear isomorphic to general volatile equilibrium model but using only matrixes and 3-dimensional tensors instead of functional spaces and multidimensional phase diagrams. Regardless of the difficulties expected in the general case, this analytical system is appeared to be exactly solvable under some acceptable conditions.
