Abstract: We study the effectiveness of central bank liquidity injections in restoring bank credit supply following a wholesale funding dry-up. We combine the Italian credit registry with bank security-level holdings and analyze the transmission of the European Central Bank 3-year Long Term Refinancing Operation. Exploiting a regulatory change that expands the pool of eligible collateral, we show that banks more affected by the dry-up use the central bank liquidity to restore credit supply, while less affected banks to increase their holdings of high-yield government bonds. Unable to completely switch from affected banks during the dry-up, firms benefit from the intervention.

Abstract: We study the design of lender of last resort interventions and show that the provision of long-term liquidity incentivizes purchases of high-yield short-term securities by banks. Using a unique security-level dataset, we find that the European Central Bank’s three-year Long-Term Refinancing Operation incentivized Portuguese banks to purchase short-term domestic government bonds that could be pledged to obtain central bank liquidity. This “collateral trade” effect is large, as banks purchased short-term bonds equivalent to 8.4% of amounts outstanding. The steepening yield curve and the resumption of public debt issuance are consistent with the equilibrium effects of the collateral trade.

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.
