Abstract: We 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 the effect of regulatory limits on household leverage on residential mortgage credit, house prices, and banks’ portfolio choice. Combining supervisory loan level and house price data, we examine the introduction of loan-to-income and loan-to-value limits on residential mortgages in Ireland. Mortgage credit is reallocated from low- to high-income borrowers and from high- to low-house price appreciation areas, cooling down, in turn, “hot” housing markets. Consistent with a bank portfolio choice channel, banks more affected by the limits drive this reallocation and increase their risk-taking in their securities holdings and corporate credit, two asset classes not targeted by the policy.

Abstract: We show that cheap credit to impaired firms has a disinflationary effect. By helping distressed firms to stay afloat, this “zombie credit” creates excess production capacity that, in turn, puts downward pressure on markups and product prices. We test this mechanism by exploiting granular inflation and firm-level data from eleven 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, average firm markups and product prices, lower investment and productivity, and an increase in aggregate sales as well as material and labor cost. Our results are stronger for prices of non-tradable products, which are more affected by local credit markets, and hold at the firm level, where we document spillover effects to healthy firms in markets with high zombie credit.
