Using a novel dataset, we study intraday trades of overnight general collateral repurchase agreements (repos) on Italian government bonds. We focus both on repos cleared by central counterparties (CCPs) and traded bilaterally. Intraday bond supply, liquidity and duration significantly affect the spread of repo rates over the European Central Bank (ECB) deposit rate, but after the ECB quantitative easing interventions this impact is much reduced. During the European sovereign debt crisis, the increase in margins further deteriorates repo costs, creating a negative procyclical effect. Once we control for the impact of margin costs, CCP-based repos do not appear to be significantly cheaper than bilateral repos. We also show that bonds with lower liquidity and specialness, greater supply and longer duration are more likely to be selected as collateral. However, during the crisis, CCP-repo borrowers choose collateral bonds with higher liquidity and lower duration to reduce margin and repo trading costs

We study the dynamics of specialness for 1-day repo contracts on Italian government bonds over a 10-year sample period. As predicted by Duffie's (1996) model, our results show that collateral supply is a significant factor for specialness. However, we enrich that finding by also showing a clear impact from repo liquidity, collateral riskiness, information uncertainty and short-selling proxies, revealing the importance of speculative bond demand for specialness. During crisis periods, bond fire sales and European Central Bank interventions also have a large impact on repo specialness. We identify recurrent patterns for specialness around bond auctions. Specialness increases steadily from the auction announcement date until a few days before the auction settlement date, which is consistent with overbidding behavior and a short selling of treasuries (via reverse repos) from primary dealers ahead of auctions.
