  • The level of implied credit volatility

    The level of implied volatility is a widely used indicator for risk appetite, and, on the individual company level, for the uncertainty related to future earnings. It is also considered a good measure of equity-market risk, because the higher the implied volatility the higher the price of equity options, and thus the higher the cost of insuring against equity-market downturns. Corporate bond spreads reflect the compensation that the investors demand for taking on credit risk. While the debt and equity markets’ estimates of risk, as explained by the Merton model, tend to move together, temporary disconnections do occur. The combination of low levels of implied equity volatility and wide credit spreads suggests the potential for the credit spreads to tighten, as the divergence in the equity and credit market eventually gets corrected. Conversely, when implied equity volatility appears high relative to credit spreads, credit markets are more optimistic about business risks in the corporate sector. The decoupling in the second half of 2003, however, was not an indication that credit spreads were rich relative to implied equity volatility. Rather credit markets were faster to cash in on the reduced risks in the corporate sector because of the massive balance sheet deleveraging, especially in the telecom sector.

    Corporate managers were selling off assets, issuing equity and keeping cash for the debtholders, as opposed to using the cash to buy back stock for the first time in 10 years. By the end of the year, equity volatility came down significantly, closing the gap in the assessment of risk.
