Repo-based interventions, including a DFA tap in October 2022 that restored repo specialness for tapped ISINs, eased market stress without altering debt levels. However, 2022 repo rates rose due to high demand against dealer-segmented supply priced at market-clearing levels. The repo market functions as a liquidity redistribution channel during Eurosystem balance-sheet normalization, with rates reflecting central-bank liquidity scarcity. Hedge funds, constrained by limited dealer relationships, may have exerted downward pressure on rates. Central banks must account for segmented dealer markets in policy design, while active DMO participation can enhance collateral availability, stabilize rates, and improve trading conditions. A regression analysis shows Eurosystem cash market purchases reduced daily repo rates by 0.304%, with stronger impacts on longer maturities. DFA’s net repo position, expressed as a percentage of holdings, indicates net lending (positive) or borrowing (negative), with all trades conducted via central counterparty. The study underscores coordination between monetary and debt-management policies, particularly through securities-lending facilities.
