Abstract:
We propose a novel explanation for the observed increase in the correlation of commodity prices over the past decade. In contrast to theories that rely on the increased influence of financial speculators, we show that price correlation can increase as a result of a decline in interest rates. More generally, we examine the effect of interest rates on the volatility and correlation of commodity prices, theoretically through the framework of Deaton and Laroque (1992) and empirically via a panel GARCH model. In theory, we show that lower interest rates decrease the volatility of prices, as lower inventory costs promote the smoothing of transient shocks, and can increase price correlation if common shocks are more persistent than idiosyncratic shocks. Empirically, as predicted by theory, we find that price volatility attributable to transitory shocks declines with interest rates, while, particularly for metals prices, price correlation increases as interest rates decline.

42. Evaluating the Forecasting Performance of Commodity Futures Prices

Abstract:
Commodity futures prices are frequently criticized as being uninformative for forecasting purposes because (1) they seem to do no better than a random walk or an extrapolation of recent trends and (2) futures prices for commodities often trace out a relatively flat trajectory even though global demand is steadily increasing. In this paper, we attempt to shed light on these concerns by discussing the theoretical relationship between spot and futures prices for commodities and by evaluating the empirical forecasting performance of futures prices relative to some alternative benchmarks. The key results of our analysis are that futures prices have generally outperformed a random walk forecast, but not by a large margin, while both futures and a random walk noticeably outperform a simple extrapolation of recent trends (a random walk with drift). Importantly, however, futures prices, on average, outperform a random walk by a considerable margin when there is a sizeable difference between spot and futures prices.

43. Did Easy Money in the Dollar Bloc Fuel the Global Commodity Boom?

Abstract:
Among the various explanations for the runup in oil and commodity prices of recent years, one story focuses on the role of monetary policy in the United States and in developing economies. In this view, developing countries that peg their currencies to the dollar were forced to ease their monetary policies after reductions in U.S. interest rates, leading to economic overheating, excess demand for oil and other commodities, and rising commodity prices. We assess that hypothesis using the Federal Reserve staff’s forward-looking, multi- country, dynamic general equilibrium model, SIGMA. We find that even if many developing country currencies were pegged to the dollar, an easing of U.S. monetary policy would lead to only a transitory runup in oil prices. Instead, strong economic growth in many developing economies, as well as shortfalls in oil production, better explain the sustained runup in oil prices observed until earlier this year. Moreover, a closer look at exchange rates and interest rates around the world suggests that the monetary policies of many developing economies, including in East Asia, are less closely influenced by U.S. policies than is frequently assumed.

Afghanistan Research and Evaluation Unit (AREU)
Abstract:
In 2004 and 2005, the Afghanistan Research and Evaluation Unit undertook a series of focused studies of commodity chains in six key sectors to gain an insight into the experience of Afghan businesses. Specifically, the studies investigated trade routes for the commodities, the number and types of market players, choice of products and the role of the state in setting regulations and standards. The final report synthesises the findings from this research.
