PEG

The term peg describes a permanent exchange rate between two different assets. In cryptocurrency markets, the term is most commonly used to describe stablecoins that are designed to maintain a constant value relative to a fiat currency, usually the US dollar. A token that uses a peg system will attempt to maintain its value at one dollar per coin.

The projects use different methods to maintain their peg. Some stablecoins use central issuers to back their currency with reserves that include cash and short term government bonds. The reserves that these entities hold exist to enable customers to redeem their assets at predetermined values. The other model uses crypto assets that are secured in smart contracts to combat price changes through overcollateralization. A smaller group of projects has experimented with algorithmic systems that adjust supply automatically to keep prices stable.

Market confidence and liquidity levels between two assets determine the success of maintaining a peg. Users who perceive strong backing combined with dependable redemption processes will maintain their buying at the target price. When confidence weakens or large redemptions occur, the asset can trade above or below its intended level. The market experiences temporary price changes that occur during times of market pressure.

The relationship between pegs and stablecoins establishes their fundamental importance for cryptocurrency markets because stablecoins serve as the main currency for trading and lending activities and all decentralized financial operations. The digital currencies use pegs to link their unstable value to stable traditional currency rates. The peg maintains market stability until it breaks, which leads to major market upheaval.
