The effect of bank capital on lending is a critical determinant of the linkage between financial conditions and real activity, and has received especial attention in the recent financial crisis. The authors use panel-regression techniques to study the lending of large bank holding companies (BHCs) and find small effects of capital on lending. They then consider the effect of capital ratios on lending using a variant of Lown and Morgan's VAR model, and again find modest effects of bank capital ratio changes on lending. The authors¿ estimated models are then used to understand recent developments in bank lending and, in particular, to consider the role of TARP-related capital injections in affecting these developments.
