We show that negative interest rate policy (NIRP) has expansionary effects on bank credit supply-and the real economy-through a portfolio rebalancing channel, and that, by shifting down and flattening the yield curve, NIRP differs from rate cuts just above the zero lower bound. For identification, we exploit ECB's NIRP and matched administrative datasets-including the credit register-from Italy, severely hit by the Eurozone crisis. NIRP affects banks with higher ex-ante net short-term interbank positions or, more broadly, more liquid balance-sheets. NIRP-affected banks rebalance their portfolios from liquid assets to lending, especially to ex-ante riskier and smaller firms-without
higher ex-post delinquencies-and cut loan rates (even to the same firm), inducing sizable firm-level real effects. By contrast, there is no evidence of a retail deposits channel associated with NIRP.
