The consequences of increased financial collateralization

There has been a strong upward trend in collateralization since the great financial crisis. Suitable collateral, such as government bonds, is essential for financial transactions, particularly repurchase agreements and derivative contracts. Increased collateralization poses new risks.

It is designed to contain derivatives-related credit and contagion risk through standardization, multilateral netting, and adequate collateralization. However, new risks may arise, due to the enhanced importance of a small group of global banks, institutional weaknesses of central counterparties, limited collateral availability, and cyclicality of margins,
