What Is Over-Collateralization (OC)?

Over-collateralization (OC) is the provision of collateral that is worth more than enough to cover potential losses in cases of default. It is used to effectively manage risk and involves placing an asset as collateral on a loan where the value of the asset exceeds the value of the loan. 

An over-collateralized stablecoins has a large number of cryptocurrency tokens maintained as a reserve for issuing a lower number of stablecoins. This offers a buffer against price fluctuations. 

DAI, for example, has a loan and repayment process utilizing a collateralized debt position via MakerDAO to secure assets as collateral on-chain. Users can deposit Ether or other accepted cryptocurrencies and can borrow against the value of their deposits to receive newly generated DAI. 

Collateralizing stablecoins, as they grow in demand and adoption, is not always efficient as it means collateral sitting idle could be used more productively elsewhere. Today we are seeing new innovations where stablecoins, with algorithmic controllers, can issue more coins when the price increases and buy them off the market when the price calls. This algorithmic manipulation of supply to change the price removes the requirement of collateral backing.
