- Abstract
- The change in macroeconomic conditions since the ECB’s strategy review in 2021 towards an environment characterised by above-target inflation, high interest rates, and renewed concerns about elevated government debt has been a vocal reminder of the intricate interdependencies between monetary and fiscal policies. Against this background, our paper reviews the literature on how central banks’ ability to maintain price stability is shaped by their interactions with fiscal policy and the state of the economy. According to standard models, a policy framework aimed at price stability requires suitable commitments from both monetary and fiscal authorities. When public debt burdens become too high, price stability may be at risk. The paper also draws lessons on how to mitigate such risks.

- Abstract
- European banks often borrow in repo markets, pledging domestic government bonds as collateral. As there tends to be a positive relation between the default risk of a bank and the default risk of its home country, using domestic collateral comes at a cost. Using transaction-level data on short-term repurchase agreements (repo) and taking into account the direct effect of collateral and borrower risk, we show that borrowers pay a premium of 1.1 to 2.6 basis points when they use domestic collateral. Additionally, we show that borrowers internalize this premium when making their collateral choices.

- Abstract
- We study how banks manage their liquidity among the various assets at their disposal. We exploit the introduction of the ECB’s two-tier system which heterogeneously reduced the cost of additional reserves holdings. We find that the treated banks increase reserve holdings by borrowing on the interbank market, decreasing lending to affiliates of the same group, and selling marketable securities. We also find that banks have a preference for a stable portfolio composition of liquid assets over time. Our results imply that frictions in one market for liquidity can spill over to several markets.

- Abstract
- This paper shows that the liquidation value of collateral depends on the interdependency between borrower and collateral risk. Using transaction-level data on short-term repurchase agreements (repo), we show that borrowers pay a 1.1 to 2.6 basis points premium when their default risk is positively correlated with the risk of the collateral that they pledge. Moreover, we show that borrowers internalize this premium when making their collateral choices. Loan-level credit registry data suggest that the results extend to the corporate loan market as well.

- Abstract
- This paper analyses money market developments since 2005, and examines factors that have affected money market functioning. We consider several metrics of activity in both secured and unsecured euro area money markets, and study interactions with new Basel III regulations and with central bank policies (liquidity provision, asset purchases and the Securities Lending Programme). Using aggregate data, we document that, prior to 2015, heightened financial market volatility coincided with worsening money market conditions, while higher central bank liquidity provision was associated with reduced money market stress. After 2015, the evidence is consistent with central bank asset purchases inducing scarcity effects in some money market segments, and with active securities lending supporting money market functioning. Using transactions-level money market data combined with supervisory data, we further document that the leverage ratio regulation impacts money markets at quarter-ends due to “window-dressing” effects, reducing money market volumes and rates. We also consider the macroeconomic impact of changing money market conditions, finding that the impact depends on whether frictions originate in secured or unsecured markets and on central bank policies in place.

- Abstract
- I develop and test a model explaining the gradual price decrease observed in the days leading up to anticipated asset sales such as Treasury auctions. In the model, risk-averse investors expect an uncertain increase in the net supply of a risky asset. They face a trade-off between hedging the supply uncertainty with long positions, and speculating with short positions. As a result of hedging, the equilibrium price is above the expected price. As the supply shock approaches, uncertainty decreases due to the arrival of information, investors hedge less and speculate more, and the price decreases. In line with these predictions, meetings between the Treasury and primary dealers, as well as auction announcements, explain a 2.4 bps yield increase in Italian Treasuries.
