Macro-finance asset pricing models provide a rationale for connectedness dynamics between equity and Treasury risk-neutral volatilities. In this paper, we study the total and directional connectedness, in the sense of spillover effects, between risk-neutral volatilities from the equity and Treasurymarkets. In addition, we analyze the economic and monetary drivers of connectedness dynamics. Most of the time, but especially during bad economic times, we find significant net spillovers from Treasury to equity risk-neutral volatility. The spillover channel between risk-neutral volatilities arises mainly through the government fixed income market.

This paper studies the joint behavior of equity (VIX) and Treasury (MOVE) risk-neutral volatilities to understand the total and directional connectedness between both option-based implied volatilities, as well as their economic and monetary drivers. Moreover, we analyze whether risk aversion and financial, macroeconomic and policy uncertainty affect connectedness dynamics. Most of the time, but especially during bad economic times, we find significant net spillovers from Treasury to equity risk-neutral volatility. Future and contemporaneous good times increase the spillovers from VIX to MOVE, while bad economic times increase the directional connectedness from MOVE to VIX.
