Introduction to the CBOE/CBOT 10-year U.S. Treasury Note Volatility Index®
Note: TYVIX is the NEW ticker symbol for the CBOE/CBOT 10-year U.S. Treasury Note Volatility Index (Formerly ticker VXTYN).
The CBOE/CBOT 10-year U.S. Treasury Note Volatility IndexSM (ticker symbol: TYVIX®) measures the expected volatility of the price of 10-year Treasury Note futures. The price of these futures is tied by arbitrage to the price of 10-year U.S. Treasury notes, which are a core instrument of the U.S. fixed income market. Futures on 10-year Treasury Notes are the most actively traded futures on U.S. Treasuries. CFE launched VXTY futures for trading in November 2014 and offers backcast historical data back to 2003 at Historical TYVIX Daily Prices.
TYVIX provides a measure of expected volatility specific to the fixed income market. This is important because, historically, the volatilities of equities and Treasuries have often followed distinct paths. The index is calculated from CBOT's options on 10-year Treasury futures using the same methodology as VIX®. Consequently, TYVIX represents the variability of percentage changes in the price, as opposed to the yield of 10-year Treasury notes. Price and yield volatility are related to each other through duration, and yield volatility is typically higher than bond price volatility.
