AbstractWe show how the design of central bank provisions of collateralized liquidity to banks following a wholesale funding dry-up affects their transmission. Combining Italian banks’ security-level holdings with the national credit register, we analyze the role of maturity and collateral during the ECB’s three-year Long-Term Refinancing Operations. We find that (i) long-term liquidity helped banks hit by the dry-up support their credit supply to firms; (ii) a government guarantee, by allowing these banks to expand their eligible collateral, was necessary for the transmission to firms; and (iii) banks used most liquidity to buy government bonds.

Abstract: I develop a model where the sovereign debt capacity depends on the capitalization of domestic banks. Low-capital banks optimally tilt their government bond portfolio toward domestic securities, linking their destiny to that of the sovereign. If the sovereign risk is sufficiently high, low-capital banks reduce private lending to further increase their holdings of domestic government bonds, lowering sovereign yields and supporting the home sovereign debt capacity. The model rationalizes, in the context of the eurozone periphery, the increase in domestic government bond holdings, the reduction of bank credit supply, and the prolonged fragility of the financial sector.

Abstract: We analyze how regulatory constraints on household leverage—in the form of loan-to-income and loan-to-value limits—affect residential mortgage credit and house prices as well as other asset classes not directly targeted by the limits. Supervisory loan level data suggest that mortgage credit is reallocated from low- to high-income borrowers and from urban to rural counties. This reallocation weakens the feedback loop between credit and house prices and slows down house price growth in “hot” housing markets. Consistent with constrained lenders adjusting their portfolio choice, more-affected banks drive this reallocation and substitute their risk-taking into holdings of securities and corporate credit.

Abstract: We show that cheap credit to impaired firms has a disinflationary effect. By helping distressed firms to stay afloat, “zombie credit” can create excess production capacity, and in turn, put downward pressure on markups and prices. We test this mechanism exploiting granular inflation and firm-level data from twelve European countries. In the cross-section of industries and countries, we find that a rise of zombie credit is associated with a decrease in firm defaults and entries, firm markups and product prices; lower productivity; and, an increase in aggregate sales as well as material and labor cost. These results hold at the firm-level, where we document spillover effects to healthy firms in markets with high zombie credit. Our partial equilibrium estimates suggest that without a rise in zombie credit post-2012, annual inflation in Europe during 2012-2016 would have been 0.45 percentage points higher.
