The paper aims to develop a methodology for the exploitation of commercial banks'
portfolio behaviour models in the implementation of macroeconomic policy. As it has been
shown, for the attainment of a chosen set of macroeconomic targets, it can be determined a
sufficient, reconstruction of the consolidated commercial banks' portfolio, which, in its turn, can
be succeeded in via a large number of alternative government intervention packages. The four
successive stages of the methodology comprise: estimation of alternative bank portfolio
behaviour models and selection of the prevailing specification; distinction of strategic central
government targets that are better explained by the endogenous variables of the prevailing
specification; determination of the desired reconstruction in the consolidated banking sectors'
portfolio, given the desired changes in the macroeconomic targets, and finally; calculation of
the alternative central government intervention packages. The empirical demonstration,
regarding the Greek case, reveals that such a methodology would be of primary importance for
both the policy makers and the monetary authorities of any country.
