Item Open Access Dynamic risk spillovers between gold, oil prices and conventional, sustainability and Islamic equity aggregates and sectors with portfolio implications(Elsevier B.V., 2017) Mensi, W.; Hammoudeh, S.; Al-Jarrah, I. M. W.; Sensoy A.; Kang, S. H.This paper investigates the time-varying equicorrelations and risk spillovers between crude oil, gold and the Dow Jones conventional, sustainability and Islamic stock index aggregates and 10 associated disaggregated Islamic sector stock indexes (basic materials, consumer services, consumer goods, energy, financials, health care, technology, industrials, telecommunications and utilities), using the multivariate DECO-FIAPARCH model and the spillover index of Diebold and Yilmaz (2012). We also conduct a risk management analysis at the sector level for commodity-Islamic stock sector index portfolios, using different risk exposure measures. For comparison purposes, we add the aggregate conventional Dow Jones global index and the Dow Jones sustainability world index. The results show evidence of time-varying risk spillovers between these markets. Moreover, there are increases in the correlations among the markets in the aftermath of the 2008–2009 GFC. Further, the oil, gold, energy, financial, technology and telecommunications sectors are net receivers of risk spillovers, while the sustainability and conventional aggregate DJIM indexes as well as the remaining Islamic stock sectors are net contributors of risk spillovers. Finally, we provide evidence that gold offers better portfolio diversification benefits and downside risk reductions than oil. © 2017 Elsevier B.V.Item Embargo Three channels of monetary policy international transmission: Identifying spillover effects from the US to China(Elsevier Inc., 2022-05-02) Zhang, M.; Şensoy, Ahmet; Cheng, F.; Zhao, X.We identify and compare three channels through which the adjustment of US monetary policy spills over into China, including trade, exchange rate, and financial channels. A proxy vector autoregression model, with a high-frequency identification strategy, is applied to measure the causal effect of monetary policy shocks to the fundamentals of China’s economy. The analysis reveals that tightness in US monetary policy increases inflation in China by 0.2% and drives down output by 1%. We also find that the spillover effect from the US to China is immediate and significant through each of the three channels. Furthermore, the financial channel is significant in terms of its effect on interest rate expectations and long-term financing premia for Chinese companies. Our results support the notion of the financial channel as a key transmission mechanism for cross-country spillovers of monetary policy, which should be of much interest to participants in financial markets.
