    Spillover dynamics effects between risk-neutral equity and treasury volatilities
    (Springer, 2022) González Urteaga, Ana; Nieto, Belén; Rubio, Gonzalo; Enpresen Kudeaketa; Institute for Advanced Research in Business and Economics - INARBE; Gestión de Empresas; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
    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 Treasury markets. 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.

    Guarantee requirements by European central counterparties and international volatility spillovers
    (JAI Press, 2022) González Urteaga, Ana; Rubio Irigoyen, Gonzalo; Enpresen Kudeaketa; Institute for Advanced Research in Business and Economics - INARBE; Gestión de Empresas
    This analysis addressed the potential systemic effects of guarantee requirements by central counterparties. Using data from the Spanish BME and German Eurex central clearing counterparties and controlling for tail risk and monetary and real activity variables, we found a significant, positive, and robust relationship between the guarantees required and the spillover or total connectedness effects among nine financial assets in the Spanish, United States, and German capital markets. Bad economic times also had a significant incremental effect on the relationship between guarantees and connectedness. These findings are robust across central clearing corporations and futures contracts in the IBEX 35, DAX 30, and EURO STOXX 50. In addition, an event study indicated that global spillover effects tend to increase before central counterparty institutions raise their guarantees. The implication of the findings is that European clearing institutions react to rather than cause bad economic times.
