Stablecoins were designed—in part—to maintain parity with fiat currencies. Typically, this is the United States Dollar (USD). However, several stablecoins have been unable to do this.
In this analysis, we look at three stablecoins to examine which has been able to best maintain an equal exchange-rate with the dollar. We examine Tether (USDT), True USD (TUSD), and Paxos Standard (PAX).
Tether
The price of Tether (USDT) on Bittrex is analyzed at one-hour intervals from Jun 2018 to Apr 2019.
Tether is the largest stablecoin, having a market capitalization value of $2,191,261,067. We are going to analyze the price movement from Jun 2018 to Apr 2019 to see if it has significantly deviated from the dollar.

The standard deviation is a measure that is used to quantify the amount of variation or dispersion of a set of data values. A low standard deviation indicates that the data points tend to be close to the mean of the set, while a high standard deviation indicates that the data points are spread out over a wider range of values.
This is shown below the USDT/USD price chart:

Summary of Analysis
To determine which stablecoin has maintained closest parity to USD, let’s compare the result above:TrueUSD
TrueUSD has long periods in which maintains relative parity to the dollar. However, it also has extremes values which skew the data significantly, as evidenced by the fact that it traded 0.0201 SD away from the mean for a short period of time.Tether
Conversely, the highest that Tether has traded away from the mean was 0.015. While Tether fluctuates more than TrueUSD, the limits are smaller and the price reverts back in a short period of time. As mentioned above, it never traded more than 0.015 standard deviations away from the mean.Paxos Standard
Paxos Standard has the least amount of fluctuations. While the time in which it traded more than 0.006 standard deviations away from the mean is the same as Tether and True USD, the fluctuations were much smaller. This was evidenced by the maximum value reached of 0.01, compared to 0.015 and 0.02 for tether and True USD respectively. This has occurred in part due to the fact that PAX has never traded below $1. To summarize, our analysis found that the stablecoin PAX has achieved the closest parity to the dollar, followed by Tether and True USD.
