VXTYN Measures Volatility in U.S. Treasuries and Potential Spillover Effect

by Bill Luby

Recently I have been highlighting some non-traditional measures of volatility and risk in the financial markets, including VXEEM (CBOE Emerging Markets ETF Volatility Index); DXJ (WisdomTree Japan Hedged Equity Fund); and DBV (PowerShares DB G10 Currency Harvest Fund). Part of my intent in focusing some attention on these largely under-the-radar indices and ETPs is to get more investors to think about risk more broadly across geographies and asset classes.

One asset class that should absolutely be watching closely by even those stubbornly equity-centric investors (and I know you are out there in larger numbers than you care to admit) is U.S. Treasuries. Of course U.S. Treasuries come in quite a few flavors, but the most important is probably the U.S. 10-Year Treasury Note. In a display of impeccable timing, last month the CBOE and the CFE teamed up to launch a new volatility index based on this security: CBOE/CBOT 10-year U.S. Treasury Note Volatility Index (VXTYN).

In the chart below, I show the path of VXTYN and the SPX going back to January 10, 2013, which is the beginning of the historical data for VXTYN provided by the CBOE. Note that VXTYN only began rising in May and when hit has made a substantial move up, that has preceded a decline in stocks.

Just for fun, I am also including a chart that shows a 21-day rolling average of the correlation between VXTYN and the SPX. Here the relationship between the swings in correlation and subsequent moves in stocks may be easier to visualize. With less than months of historical data to draw on, I would caution against jumping to conclusions regarding correlation and causation, but at the very least I thought this graphic might provide some food for thought.

Last but not least: did you know there are ETPs for placing bets on whether the Treasury yield curve will get steeper or flatter? I highlighted these products back in 2010 in Treasury Yield Curve ETNs and Volatility; they are known formally as the iPath US Treasury Steepener ETN (STPP) and the iPath US Treasury Flattener ETN (FLAT).
