Euro repo market acts as shock absorber in stress periods
A new ECB working paper finds the euro-denominated repo market acts as a shock absorber during financial stress. Network analysis of transaction-level data reveals lower spreads and stable volumes in stress periods.
Core-periphery structure absorbs shocks
The euro-denominated repo market exhibits a core–periphery structure, where a small group of highly active institutions conducts most trading with a larger, less active periphery.
Analysis of transaction-level data from 2021 to mid-February 2025 reveals that connectivity within this institutional network intensifies during periods of financial stress.
Despite this, trading volumes and repo spreads at the sectoral level remain broadly stable.
Crucially, for the euro repo market as a whole, financial stress is associated with lower spreads, indicating its resilience and function as a shock absorber.
This adjustment primarily occurs through pricing, rather than significant changes in activity or contractual terms like haircuts and maturities, which remain stable.
The study utilized network metrics and regression techniques, defining financial stress via the Composite indicator of systemic stress (CISS), to map activity between counterparties and quantify effects on key market variables.
Liquidity lifeline under scrutiny
Repurchase agreements are vital for circulating liquidity and enabling short-term collateralised cash loans throughout the financial system.
The euro repo market has become the largest segment of the euro money market, growing significantly and accounting for 56 percent of daily transactions.
However, these markets have faced repeated episodes of stress, including disruptions during the 2007/08 financial crisis and recent episodes in 2020 and 2022.
Such events highlight how vulnerabilities can propagate systemic risk.
Non-bank financial institutions (NBFIs) play an increasingly prominent role, making their dynamics under stress a key concern for financial stability and monetary policy transmission.
A crucial shock absorber
This paper offers crucial empirical evidence on the euro repo market's resilience, confirming its role as a vital shock absorber during periods of stress.
The finding that spreads decline under stress is particularly noteworthy, highlighting effective pricing adjustments rather than market dysfunction.
For policymakers, this analysis is invaluable for refining financial stability frameworks, especially concerning non-bank financial institutions.
