Eurosystem's Asset Purchases and Money Market Rates

Some Euro area money market rates have been standing below the deposit facility rate since 2015, which coincided with the start of the Eurosystem’s public sector purchase program (PSPP). In this paper, we explore empirically the interactions between the PSPP and short term secured money market rates (repo rates). We document different channels through which asset purchases may affect the various segments of the Euro area repo market. Using proprietary data from the PSPP purchases and transactions made on the repo market for specific securities (“special”), our results show that the PSPP has contributed to push down repo rate, in particular prior to January 2017. On average, purchasing 1% of a bond outstanding is associated with a decline in its repo rate of -0.78 bps.
