Summary
- Short term (1M and 3M) implieds are expensive to realised for GBP/USD while they are fairly valued to realised for EUR/USD, USD/JPY and AUD/USD.
- We find the volatility curves for EUR/USD, USD/JPY, GBP/USD and AUD/USD suggests buying 1Y implieds and selling 1W implieds.
Implied vs Realised Volatility – What’s Cheap/Expensive?
We use a range of realised volatility measures and look at realised with and without major events (FOMC, ECB, BoJ, US CPI and NFP days). Our latest update finds the following:
- EUR/USD: 3M implieds sit within the range of all measures of realised vol with and without key events (Tables 1 and 2, Charts 1 and 2).
- USD/JPY: 3M implieds are fairly valued to realised vol with and without key events (Tables 3 and 4, Charts 1 and 3).
- GBP/USD: 3M implieds are expensive to realised vol (Chart 1 and Table 5).
- AUD/USD: 3M implieds are fairly valued to realised vol (Chart 1 and Table 7).
Implied Volatility Slope
We analyse the slope of the ATM implied vol curve across tenors ranging from 1-week to 1-year to establish its steepness/flatness.
We also consider Z-scores of the slope values over the past year to establish how extreme the latest values are. We show the ATM volatility slope on a heatmap where the values correspond to the latest slope value, and the shading corresponds to the z-score of that slope value over the past year.
Our latest data finds the following:
- EUR/USD: The 1Y/1W slope (1Y minus 1W) is over one standard deviation below its mean value over the past year (Charts 4 and 6). This suggests buying 1Y EUR/USD implieds and selling 1W implieds.
- USD/JPY: The 1Y/1W slope (1Y minus 1W) is over one standard deviation below its mean value over the past year (Charts 5 and 7). This suggests buying 1Y USD/JPY implieds and selling 1W implieds.
- GBP/USD: The 1Y/1W slope (1Y minus 1W) is over one standard deviation below its mean value over the past year (Charts 8 and 10). This suggests buying 1Y GBP/USD implieds and selling 1W implieds.
- AUD/USD: The 1M/1W slope (1M minus 1W) is over one and a half standard deviations below its mean value over the past year (Charts 9 and 11). This suggests buying 1M AUD/USD implieds and selling 1W implieds.
Different Measures of Volatility
Tables 1-8 show the realised volatility (with and without big events) for each currency we track using each of the different estimators along with the corresponding implied volatilities.
Volatility Risk Premium
Tables 9-12 show the volatility risk premium (implied volatility minus realised volatility) for each currency across each of the different estimators.
Volatility Risk Premium Percentiles
Tables 13-16 show the 5-year percentiles of the volatility risk premium across each currency, estimator, and period (1 month to 1 year).
Appendix
We recently published a note comparing different measures of realised volatility. This includes the most common measure of realised volatility – close-to-close volatility (also referred to as historical volatility), which is just the standard deviation of (logarithmic) returns over a historical period.
We also consider range-based volatility estimators that make use of intraday price data (e.g., open, high, low, and close) to derive an estimator of realised volatility that may be more precise and efficient than the standard close-to-close measure.
Notably, we implemented five different measures of realised volatility – Table 13 provides a summary of each.
In this report, we update the estimators with the latest data and look at the volatility risk premium across several currencies we track.
