Does Implied Volatility Imply Volatility—in Bonds?
The Journal of Fixed Income, 2001The authors investigate the relationship between the implied volatility derived from option contracts on U.S. Treasury bond futures and the actual volatility observed in these securities. Research has suggested that implied volatility in stock options correctly forecasts realized volatility in stock prices; the authors find the same is true in bonds ...

The pricing of corporate credit can be succinctly understood via the credit-implied volatility (CIV) surface. We invert it each month from the firm-by-maturity panel of CDS spreads via the Merton model, transforming CDS spreads into units of asset volatility. The CIV surface facilitates direct comparison of credit spreads at different "moneyness" (firm

AN EXPLICIT IMPLIED VOLATILITY FORMULA
International Journal of Theoretical and Applied Finance, 2017We show that an explicit approximate implied volatility formula can be obtained from a Black–Scholes formula approximation that is 2% accurate. The relative error of the approximate implied volatility is uniformly bounded for options with any moneyness and with arbitrary large or small option maturities and volatilities, including for long dated ...

THE ROLE OF IMPLIED VOLATILITY IN VOLATILITY COMBINING FORECASTS
International Journal of Economics and Business Research, 2023This study explores the role of implied volatility (IV) in volatility combining forecasts for S&P 500 and DAX markets. A range of GARCH models, ad hoc models and STES models were developed to identify the best performing model that served as a base model for subsequent combining process, of which GJRGARCH model appeared to be the superior model among ...

ASYMPTOTICS OF IMPLIED VOLATILITY IN LOCAL VOLATILITY MODELS
Mathematical Finance, 2010Using an expansion of the transition density function of a one‐dimensional time inhomogeneous diffusion, we obtain the first‐ and second‐order terms in the short time asymptotics of European call option prices. The method described can be generalized to any order.
