In this paper, we show that large inflows into commodity investments, a recent phenomenon known as financialization, has changed the behavior and dependence structure between commodities and the general stock market. The common perception is that the increase in comovements is the result of...

This paper studies comovements in commodity futures markets. We compare factor models with respect to their fit of commodity return comovements. A model based on traded long-short portfolio returns outperforms a macroeconomic model, and explains 96% of the realised comovement. Dissecting the...

The paper studies the return-volatility relationship in a range of commodities. We develop a commodity price model and show that the volatility of price changes can be positively or negatively related to demand shocks. An “inverse leverage effect” – the volatility is higher following...

Commodity is one of the most volatile markets and forecasting its volatility is an issue of paramount importance. We study the dynamics of the commodity markets volatility by employing fractional stochastic volatility and heterogeneous autoregressive (HAR) models. Based on a high-frequency...

This paper studies the effects of financial speculation on commodity futures returns, using publicly available data from the US Commodity Futures Trading Commission, aggregated by trader groups. We exploit the heteroskedasticity in the weekly data to identify exogenous variation in speculators'...

This paper investigates price jumps in commodity markets. We find that jumps are rare and extreme events but occur less frequently than in stock markets. Nonetheless, jump correlations across commodities can be high depending on the commodity sectors. Energy, metal and grains commodities show...

Negative policy spillovers can undermine the social effectiveness of well-intentioned regulations. We evaluate whether environmental regulations that shifted electricity generation from coal to natural gas, reducing emissions, had an effect on electricity price volatility. We use emergency...

This paper studies commodity spot, forward, and futures prices under a continuous-time setting. Our model considers a representative firm, which uses an input commodity to produce an output commodity, stores the commodity, and trades forward or futures commodities to hedge. Through the...

We uncover stylized facts of commodity futures price and volatility dynamics in the post-financialization period and find a factor structure in daily commodity volatility that is much stronger than the factor structure in returns. The common factor in commodity volatility relates to stock market...

The aim of this paper is to investigate the impact of the financialization of commodity markets on the profitability of strategies based on momentum and term structure. The performance of an array of portfolios from double-sorts on non-commercial traders' participation, historical returns and...
