Interdependence among agricultural commodity markets, macroeconomic factors, crude oil and commodity index

Cross-correlations between crude oil and agricultural commodity markets

In this paper, we investigate cross-correlations between crude oil and agricultural commodity markets. Based on a popular statistical test proposed by Podobnik et al. (2009), we find that the linear return cross-correlations are significant at larger lag lengths and the volatility cross-correlations are highly significant at all of the lag lengths under consideration. Using a detrended cross-co...

Speculative bubbles in agricultural commodity markets

Numerous factors have been proposed in the literature as explaining the recent commodity price movements. In this paper we focus on one of the most widely discussed factors, the impact of speculative bubbles. We investigate whether commodity prices during the spike of 2007–2008 might have deviated from their intrinsic values based on market fundamentals. To do this, we use a bootstrap methodolo...

Mean and Variance Dynamics between Agricultural Commodity Prices and Crude Oil Prices

Global oil prices, macroeconomic fundamentals and China's commodity sector comovements

This paper investigates the common movements of commodity sectors in China as well as the economic underpinnings of the comovements. We employ a Bayesian dynamic latent factor model to disentangle the common and idiosyncratic sector-specific factors of the prices of a group of China's commodity sectors: petrochemicals, grains, energy, non-ferrous metals, oils & fats, and softs. The results indi...

Correlation in Volatility Among Related Commodity Markets

Related commodity markets have two characteristics: (i) they may follow similar volatility processes; and (ii) such markets are frequently represented by a market aggregate or index. Indices are used to represent the performance and time series properties of a group of markets. An important issue regarding the time series properties of an index is how it reflects the time series properties of i...
