    What Is a Peg?

    A “peg” is a specified price for the rate of exchange between two assets. This is in direct contrast to “floating” currencies which have no hard price target and follow looser monetary policy.

    In the usual global context of currencies, a peg allows foreign currencies to be traded for the chosen base currency at a fixed exchange rate. Some of the most common benefits of establishing a peg are to encourage trade between nations, to reduce the risks associated with expanding into broader markets and to stabilize macro-economic activity.

    In the context of cryptocurrency, a peg refers to the specific price that a token is aiming to stay at. The majority-case use of a peg is for stablecoins; stablecoins are cryptocurrency assets that maintain their value over a long period of time. Notable examples include USDT, DAI and FRAX, all of which are pegged to $1. The dollar itself is “soft-pegged” to the consumer price index (CPI) which tracks a basket of goods.

    Stablecoins maintain their peg through contraction or dilution of the total supply. The changes in the token supply will change the relative price of each token, until it reaches the desired peg. Collateralized stablecoins such as USDT and DAI are minted and burned as appropriate, with the newly minted tokens receiving collateral backing in the form of other digital assets. 

    Algorithmic stablecoins maintain their peg through a combination of collateralization and utilising complex smart contract algorithms that contract and expand the supply based on various market factors.
