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. Collateral prices and haircuts are pro-cyclical, which means that collateralized transactions flourish when assets values rise and slump when asset values decline. This creates links between leverage, asset prices, hedging costs and liquidity across many markets. Trends are mutually reinforcing and can escalate into fire sales and market paralysis. Central clearing cannot eliminate this escalation risk. The collateral policies of central banks have become more important.
