Stablecoins have gained significant popularity in the cryptoasset ecosystem due to their promise to maintain a peg relative to a fiat currency, a commodity or a basket of assets, ensuring stability over time. However, the maintenance of this peg is not always guaranteed and stablecoins can experience significant price deviations from their intended value. In this section, we introduce indicators that can be used to get a better understanding of some of the risks associated with stablecoins. Some of these indicators are related to historical peg stability.
The Peg stability chart (below) tracks the deviation of stablecoin prices from their promised peg, demonstrating the historical ability of stablecoins to maintain stable prices over the past one, two and three years and for all the available price data since 2019. Please interact with the chart to see how often the price was above or below the peg and how often it fell in specific price ranges, and to get summary statistics for the cases when the price deviated from its peg by more than a certain threshold.
Please note that this and other peg stability charts below are based on the prices on exchanges (secondary market) and do not consider the possibility of issuing or redeeming stablecoins directly from a stablecoin issuer (primary market). The User agreements table at the end of this section gives an overview of stablecoin issuance and redemption terms. Subject to data availability, future iterations of the dashboard may also cover the primary market and its importance for price stability in more detail.
Notes: 1. The bars (shaded areas) to the right and left of the chart represent the cumulative count of outliers and should not be mistaken for standard histogram bar representations. 2. The density curve is included for illustrative purposes only and should not be used to draw predictive inferences about the underlying price distribution. 3. ‘Occurred on x hours’ means that the price of one unit was at least the dollar price shown within x hours which may or may not have been consecutive. 4. The chart is based on the pricing data from 14 centralised exchanges (see Methodology for details) and does not consider direct redemption or issuance prices from stablecoin issuers.
Depeg statistics
The ‘Breaking the band’ calculator highlights the cases when the price of a stablecoin has moved outside the specific range of its target value. Please select a desired threshold to find out how often and for how long a stablecoin depegged during specific time periods. The calculator also provides insights into the maximum and median continuous times of the depegs.
Notes: 1. The calculator displays the number of instances when the price of the stablecoin has moved above, below or both above and below the selected threshold. The term ‘Instances’ refers to the total number of occurrences when a stablecoin deviated from its peg, regardless of the duration of each occurrence. ‘Overall time’ indicates the total duration of all observations that fall outside the specified interval. ‘Continuous time’ characterises an instance by detailing the consecutive number of hours during which the stablecoin’s price remained above, below or around (above and below simultaneously) the designated threshold, such as two consecutive hours, three consecutive hours and so forth. ‘Max’ represents the highest number of hours recorded for a single instance, while ‘Median’ signifies the typical duration (measured in hours) of an instance. 2. The calculator is based on the pricing data from 14 centralised exchanges (see Methodology for details) and does not consider direct redemption or issuance prices from stablecoin issuers.
