The reuse of collateral can support the efficient allocation of safe assets in the financial system. Exploiting a novel dataset, we show that banks substantially increase their reuse of sovereign bonds in response to scarcity induced by Eurosystem asset purchases. While repo rates react little to purchase-induced scarcity when reuse is low, they become increasingly sensitive at high levels of reuse. An elevated reuse rate is also associated with more failures to deliver and a higher volatility of repo rates in the cross-section of bonds. Our results highlight the trade-off between shock absorption and shock amplification effects of collateral reuse.
IFRS 9 introduces new impairment rules responding to the G20 critique that IAS 39 results in the delayed and insufficient recognition of credit losses. In a case study of a Greek government bond for the period 2009 to 2011 when Greece’s credit rating declined sharply, this study highlights the discretion that preparers have when estimating impairments. IFRS 9 relies more on management expectations and will lead to earlier impairments. However, these appear still delayed and low if compared to the fair value losses.
