Treasury Yield Implied Volatility and Real Activity
Abstract
The implied volatility from Treasury derivatives (Treasury ‘yield implied volatility’) predictsthe level and volatility of macroeconomic activity such as the growth rates of GDP, industrial
production, consumption, and employment. This predictability is robust to the inclusion of
popular forecasting variables used in the current literature. We study one potential explana-
tion for why interest rate uncertainty constitutes a useful forward-looking state variable that
characterizes risks and opportunities in the macroeconomy, namely a bank credit channel.
Consistent with this mechanism, an increase in Treasury yield implied volatility (interest rate
uncertainty) adversely impacts bank deposits, bank credit growth, and banks’ cost of capital,
as well as investments by bank dependent firms. Our study provides novel evidence that
interest rate risk impacts banks not only through levels, but also via uncertainty
