The 2007-9 .financial crisis began with increased uncertainty over funding conditions in money markets. We show that funding uncertainty can explain diverse elements of commercial banks behaviour during the crisis, including:(i) reductions in lending volumes, balance sheets, and profitability;(ii) more intense competition for retail deposits (including deposits turning into a .loss leader.);(iii) stronger lending cuts by more highly extended banks with a smaller deposit base;(iv) weaker pass-through from changes in the central bank.s policy rate to market interest rates; and(v) a binding .zero lower bound.as well as a rationale for unconventional monetary policy.
