A hard peg is an exchange rate policy, where a currency is set at a fixed rate against another currency.
Hard Peg is an exchange rate policy, where a currency is set at a fixed rate against another currency.
For example, the Chinese Yuan was pegged to the U.S. dollar at a fixed rate of 8.28 per dollar.
The fact that a currency's value is pegged to another currency or basket of currencies means that it will fluctuate against other currencies with the same ratio. A hard peg only allows for a certain amount of movement in relation to the pegged currency, creating what's called a band.
Currencies often start out with a fixed exchange rate, but in time they're allowed to float freely as market conditions dictate. That typically happens because the government no longer wants to maintain the peg due to economic or political reasons—or simply because it can't continue supporting it.
An advantage of hard pegs is that they are simple and transparent: the supply of the cryptocurrency is fixed and known. This may make them easier to implement without breaking the anonymity of transactions.
A disadvantage of a hard peg is that it can be challenging to maintain a peg if people want to use their holdings as an actual currency rather than a commodity. For example, if too many people buy the currency, there won't be enough dollars held in reserve to back all issued Tethers.
If too many people sell their holdings for dollars, maintaining the peg would also become difficult.
Currency pegging is a practice in which countries fix the value of their currency to that of another country. Pegging generally happens where a lot of trade occurs, like in East Asia. It can also happen at the global level when a group of countries, such as the European Union, agree to peg their currencies with each other.
Tying a currency to the value of another country's currency can be advantageous in several ways:
