It describes the calculation and salient features of the CBOE/CBOT 1-Year U.S. Treasury Note Volatility Index (TYVIX SM ). The second module, called TYVIX Futures Primer, describes TYVIX futures and their basic empirical properties, and the third module, called Compendium of Empirical Findings presents additional empirical facts about the index and the futures. The TYVIX Index in a Nutshell The TYVIX is the first exchange-traded volatility benchmark for U.S. Treasuries. Similar to the CBOE Volatility Index (VIX Index), TYVIX measures expected percentage changes in its underlying over a one-month period. The underlying is CBOT futures on 1-year Treasury Notes (ticker TY). TY futures are the most actively traded U.S. Treasury futures, and their volatility is aligned with the volatility of a variety of fixed income assets, such as spot Treasuries, interest rate swaps, mortgage-backed securities, and corporate bonds. TYVIX is calculated every 15 seconds from 7: am to 3:15 pm Central time and is disseminated to data vendors under the ticker TYVIX. Figure 1.

3 The historical series of TYVIX from 23 to 214 (Figure 1) shows that the index reacts strongly to sudden and extreme variations in the 1-year constant maturity Treasury yield. II. Index Calculation TYVIX is an estimate of the expected 3-day volatility of CBOT Ten-Year Treasury futures (TY), and, by extension, of the volatility of Ten-Year Treasury Notes. Like the VIX, TYVIX is model independent. It applies the VIX methodology to the market prices of OZN options on TY futures 1. The times series of daily TYVIX values as well as the TYVIX term structure may be found at www.cboe.com/tyvix. The VIX formula which forms the basis of the TYVIX calculation is: TYVIX 1* 365 1 [2e 3 r { K i K K i j F Price Pr } ( 1) 2 K ice i 2 K j K K K i K j j ATM 2 ] summarized as TYVIX 1 * expressed in percentage points. 365 VAR, the square root of annualized variance 3 This formula has its roots in theoretical results of Neuberger (199) and Carr and Madan (22) that show that the N-day variance of an asset (VAR) is approximated by the forward value of a portfolio of at- and out-of the-money N-day options on the asset. 1 The formula is consistent with a random spot rate of interest. Jamshidian (1989) has shown that when the spot rate of interest is random, the prices of related bond futures and options can be interpreted as the discounted expected value of their final payoff, with the nuance that the expectation for each expiration is now taken under a different probability measure called the forward measure for that expiration. The forward measure is a transformation of the risk-neutral measure. Following Jamshidian, Mele and Obayashi (212) have expressed the price of bond variance in terms of bond option prices. This is the basis of the formula. There are two other nuances that don t affect the essential information conveyed by XTYN. First, the formula strictly holds for European-style options and CBOT Treasury options have American-style exercise. The effect of ignoring the early exercise premium on volatility is likely to be small because the Treasury options used to calculate the index are out-of-themoney and short-dated. Second, is interpolated from adjacent futures to arrive at a 3 day measure, and each futures expiration is associated with its own forward measure.
4 In Equation (1): The variable Price Ki denotes mid-quotes of out-of-the-money puts and calls with strikes K i and K j respectively,and the average of the mid-quotes of the at-the-money put and call. K 2 K 2, where K is the strike interval associated with K, is the number of options at strike K included in the portfolio. e rτ is the interest rate factor that converts the price of each option to a forward value. F 2 The term ( 1) under the square root compensates for the error K ATM introduced by the substitution of K ATM, the strike deemed at-the-money, for the forward price. The substitution is necessary because there is usually no listed strike equal to the forward price. 365 The factor converts the 3-day variance into an annualized variance, 3 and TYVIX is defined as the square root of this annualized variance multiplied by 1 to express it in percentage points. Looking at the TYVIX formula, an immediate question arises: what should one do if there are no OZN options expiring in 3 days? This question is answered in the following numerical example which describes how the TYVIX formula is implemented step by step. Numerical Example of TYVIX Calculation Step1: Find OZN Contract Months At 3:15 p.m. CT on 11/1/214, the closest to 3-day options listed were CME OZN options expiring at 4: p.m. on 11/21/214 and on 12/26/214. Note that the CME calls these December 214 and January 215 options. They settle to December 214 TY and March 215 TY futures respectively. A 3-day variance will be interpolated from at-and-out-of-the money OZN December 214 and January 215 options.

Sources: Bloomberg, CBOE Options that are zero-bid are deemed illiquid and are excluded from the calculation. Strikes with bids of.1 correspond to cabinet trades and are also excluded. Excluded strikes are grayed out in Table 1, leaving a range of 124.5 to 129 for December 214 OZN options and 12.5 to 133.5 for January 215 OZN options. Note that as volatility rises and falls, the strike price range of options with positive bids tends to expand and contract. As a result, the number of options

Sources: Bloomberg, CBOE The theoretical at-the-money strike is the forward price, and the difference between call and put prices at this strike is equal to zero. In Table 2, we see there is no strike at which this difference is zero. The forward price must therefore be estimated by applying put call parity: F = Strike Price + e rtau * (Call Price - Put Price)
7 Put call parity holds at any strike but a more robust estimate of the forward price results if one uses the strike where the absolute difference between the call and put price is smallest. The Dec 214 strike with the closest put and call is 126.5 (difference =-.2344), highlighted in yellow, and for Jan 215 options it is 125.5 (.5469), highlighted in orange. To apply put-call parity, find r, the rate of interest to the expiration of the option, and tau, the time to expiration in year units. The rate of interest r is found by cubic spline interpolation of Treasury bill rates published at http://www.treasury.gov/resource-center/data-chart-center/interestrates/pages/textview.aspx?data=yield On 11/1/214, the rates applied to Dec 214 and Nov 215 OZN options were.444 and.35 respectively. The number of minutes in a year is 525,6. Hence tau, or time to expiration in year units was: December 214 OZN:.32263 = 15,885 / 525,6 January 215 OZN:.1261131 = 66,285 / 525,6 Substitute these values in the put-call parity formula to obtain: F1 = 126.5 + exp(.444 x.32263) *(-.234375) = 126.2656219 F2 = 125.5 + exp(.35 x.12611314) x (.546875) = 125.546899 The resulting OZN option strikes to use in the calculation are OTM Puts ATM Call & Put OTM Calls Dec 214 OZN 124.5-125.5 126 126.5-129 Jan 215 OZN 12.5-125 125.5 126-133.5 All puts with strikes smaller than the at-the-money strike are included in the calculation, as well as all calls with strikes greater than the at-the-money strike. Both at-the-money put and call are included.

9 From left to right, Table 3 columns contain: 1. The strike of the put and call K 2. 2 K 2, the number of options included at each strike, where the strike interval K is set as half the distance between adjacent strikes, or the distance from the next strike for end strikes. The strike interval is usually equal to.5 at all OZN strikes. The number of options at the 124.5 strike is 2*.5/124.5 2 = 6.4515E-5 OZN Dec 14 OZN puts 3.The mid-quotes at each strike. The mid-quote at the ATM strike is the average of the put and call mid-quotes. Thus, for Dec 214 OZN options:.4625 = average (.54688,. 265625) 4.The forward value of the option at each strike. For example, the forward value of the price of the 124.5 OZN Dec 214 call is 1.5129E-6 = exp(.444 x.32263)* 6.4515E-5*.234375. 5.The portfolio weight of the forward value of the option at each strike. For each OZN expiration,the sum of the forward values across strikes is in the bottom row labeled sum. The variance is found by substracting the adjustment factor epsilon = (F/K ATM - 1) 2 from this sum: Epsilon 1 = (126.2656219/126-1) 2 = 4.44413E-6 Epsilon 2 = (125.546899 /125.5 1)2 =1.8991E-7 Variance from December 214 OZN Options VAR 1 = 7.62767E-5-4.44413E-6 = 7.18326E-5 Variance from January 215 OZN Options VAR 2 =.167853 1.8991E-7=.167663
1 Step 5: Interpolation of a 3-Day Variance and Determination of TYVIX The last step to TYVIX is to interpolate a 3-day variance from December 214 and January 215 OZN variances, annualize the variance, take the square root and multiply by 1 to express it in percentage points: TYVIX 365 1 * ( wvar 1 (1 w) VAR 2 ) 3 VAR1 is the variance of December 214 futures from 11/1/214 to 11/21/214 and VAR2 is the variance of January 215 TY futures from 11/1/214 to 12/26/214. The weights are w and 1-w. For the purpose of the calculation, time is recorded in minutes. Thirty days = 3*24 *6 mn = 43,2 mn variance. The December 214 OZN options have 15,885 mn to expiration (525+ 14,4 + 96 = 15,885) and the January 214 OZN options have 66,285 mn to expiration (525+ 96 + 64,8=66,285). Hence, 66,285 43,2 w.458 66,285 15,885 1 w.542 Substitute the weights and variances in the formula : TYVIX 1* 365 (.458*7.18326E 5.542*.167663) 3 TYVIX 5.11 Conversion of TYVIX to TYVOL, a Yield Volatility In the fixed income market, there are two conventions for calculating and quoting volatility. The first expresses volatility as the variation of a rate of interest or yield and quotes it in basis points. The second expresses volatility as the variation of
12/19/26 5/19/27 1/19/27 3/19/28 8/19/28 1/19/29 6/19/29 11/19/29 4/19/21 9/19/21 2/19/211 7/19/211 12/19/211 5/19/212 1/19/212 3/19/213 8/19/213 1/19/214 6/19/214 11/19/214 12/19/26 5/19/27 1/19/27 3/19/28 8/19/28 1/19/29 6/19/29 11/19/29 4/19/21 9/19/21 2/19/211 7/19/211 12/19/211 5/19/212 1/19/212 3/19/213 8/19/213 1/19/214 6/19/214 11/19/214 11 the rate of return of the asset and quotes it in percentage points. VIX belongs to this second category, as does TYVIX. To facilitate the comparison between TYVIX and yield volatilities, CBOE converts the TYVIX Index to a yield volatility index called Ten-Year Treasury Yield Volatility Index (TYVOL SM ). Figure 2 shows TYVOL, TYVIX and the Merrill Option Volatility Expectations Index (MOVE index). The MOVE index is a measure of the average yield volatility of 2, 5, 1, and 2 year Treasury bonds. The derivation of TYVOL is described in a separate note titled Conversion of the TYVIX Index SM to the Ten-Year Treasury Yield Volatility Index (TYVOL SM Index).

Descriptive Statistics, TYVIX and VIX Treasuries are reputed to be less volatile than stocks. To confirm, the frequency distributions and standard statistics for TYVIX and VIX are reported in Figure 4. In the histogram on the left, the distribution of TYVIX is located to the left of the distribution of VIX. It is also more compact, less skewed and less kurtotic than VIX. Standard descriptive statistics in the top right panel of the table tell the same story in numbers.

Historical Range & Behavior of TYVIX and VIX Values Source: CBOE Futures traders are especially interested in the volatility of the underlying asset. The bottom of the right panel of Figure 4 shows statistics for the absolute daily log-return of the index. By this measure, the volatility of TYVIX is comparable to that of VIX. Figure 5.

Since these two asset classes are impacted by different factors, one would not expect their volatilities to behave in the same way. And as shown in Figure 5, they do not. There are marked differences even during the financial crisis of 28. TYVIX and VIX both peak during the third quarter, but TYVIX starts its ascent

The upper and lower bounds of the range act as reflecting barriers which lend the index the appearance of reverting to a mean. To explore the mean-reverting tendencies of TYVIX, we follow the six-month path of TYVIX conditional on its initial value. Each panel of Figure 6 shows future ranges of TYVIX from one week to six months out, starting from a different range of initial values. For example, in the first panel, initial values range from 4 to 7. The blue lines represent the initial and future ranges of TYVIX, from one week to 6 months later. The black rectangles mark the average and median values of TYVIX from one week to six months later. Figure 6.

On average, and this is also borne out by the evolution of the range of TYVIX; mean-reversion appears stronger when TYVIX is at a historically high level and less so when TYVIX is at a historically low level. b. TYVIX Volatility Premium A key attraction of volatility as an asset is its explosive behavior during tail events that impact the rate of return of the underlying asset. Investors pay a risk

The risk premium is embedded in the spread between expected and realized volatility, but is sometimes overshadowed by large forecasting errors. If forecasting errors are unbiased, the average spread should be positive. In Figure 7, we see that TYVIX indeed tends to be greater than the realized volatility of futures on 1-year Treasury notes. Exceptions occur more frequently in the period surrounding the 28 credit crisis when the market significantly underestimated future volatility. Figure 7.

TYVIX is highly sensitive to announced changes in monetary policy and to macroeconomic events that affect interest rates. The broad impact of monetary policy is captured in Figure 8, where TYVIX is overlaid on the Federal Fund Target rate. TYVIX steadily decreases during the slow ramp up of the Federal Fund Target rate from 24 to 26, but it increases more rapidly when the Federal Fund Target rate starts to cascade down in late 27. Once the rate hits bottom, TYVIX reacts to different events and news such as talk about tapering that may lift the rate.

TYVIX has followed suit and has become more sensitive to rate fluctuations. Figure 9.
