We empirically reinvestigate the issue of excess comovement of commodity prices initially raised in Pindyck and Rotemberg (1990) and show that excess comovement, when it exists, can be related to hedging and speculative pressure in commodity futures markets. Excess comovement appears when...

To improve risk management in the European Union Emissions Trading Scheme (EU ETS), the European Climate Exchange (ECX) has introduced option instruments in October 2006 after regulatory authorization. The central question we address is: can we identify a potential destabilizing effect of the...

As both speculative and hedging financial flows into commodity futures are expected to link commodity price formation more strongly to equity indices, we investigate whether these processes also create increased correlation amongst the commodities themselves. Considering U.S. oil and gas...

We proceed to an impulse-response analysis on the conditional correlations between three stock indices returns: the S&P 500, the ftse 100 and the Nikkei 225. As a first step, a general asymmetric dynamic conditional correlation (ga-dcc) model proposed by Cappiello, Engle and Sheppard [2006] is...
