A model of financialization of commodities

We analyze how institutional investors entering commodity futures markets, referred to as the financialization of commodities, affect commodity prices. Institutional investors care about their performance relative to a commodity index. We find that all commodity futures prices, volatilities, and correlations go up with financialization, but more so for index futures than for nonindex futures. The equity-commodity correlations also increase. We demonstrate how financial markets transmit shocks not only to futures prices but also to commodity spot prices and inventories. Spot prices go up with financialization, and shocks to any index commodity spill over to all storable commodity prices

Commodity prices, money and inflation

The influence of commodity prices on consumer prices is usually seen as originating in commodity markets. We argue, however, that long run and short run relationships should exist between commodity prices, consumer prices and money and that the influence of commodity prices on consumer prices occurs through a money-driven overshooting of commodity prices being corrected over time. Using a cointegrating VAR framework and US data, our empirical findings are supportive of these relationships, with both commodity and consumer prices proportional to the money supply in the long run, commodity prices initially overshooting their new equilibrium values in response to a money supply shock, and the deviation of commodity prices from their equilibrium values having explanatory power for subsequent consumer price inflation.

Primary commodity prices and macroeconomic variables : a long run relationship

In recent years, fluctuations in such macroeconomic variables as interest rates and exchange rates appear to have significantly affected primary commodity prices. This paper studies the relationship between commodity prices and various macroeconomic variables. It focuses particularly on interest rates because of the important role they play in the portfolio adjustment model, in which investors move between commodities, bonds and money as interest rates change. The paper concludes that there is a long run quantifiable relationship between real interest rates and real commodity prices, but not between real commodity prices and either consumer prices or the money supply. Commodity prices in nominal terms strongly affect consumer prices but not the reverse - and some groups of commodity prices can be reliable indicators of movements in consumerprices. Changes in the money supply affect commodity prices, but not the reverse, and the relationship is not quantifiable.Insurance&Risk Mitigation,Economic Theory&Research,Markets and Market Access,Access to Markets,Environmental Economics&Policies

Commodity Currencies and the Real Exchange Rate

This paper examines whether the real exchange rates of commodity-exporting countries and the real prices of their commodity exports move together over time. Using IMF data on the world prices of 44 commodities and national commodity export shares, we construct new monthly indices of national commodity export prices for 58 commodity-exporting countries over 1980-2002. Evidence of a longrun relationship between national real exchange rate and real commodity prices is found for about onethird of the commodity-exporting countries. The long-run real exchange rate of these ‘commodity currencies’ is not constant (as would be implied by purchasing power parity-based models) but is time-varying, being dependent on movements in the real price of commodity exports.

Global commodity cycles and linkages a FAVAR approach

In this paper we examine linkages across non-energy commodity price developments by means of a factor-augmented VAR model (FAVAR). From a set of non-energy commodity price series, we extract two factors, which we identify as common trends in metals and a food prices. These factors are included in a FAVAR model together with selected macroeconomic variables, which have been associated with developments in commodity prices. Impulse response functions confirm that exchange rates and of economic activity affect individual nonenergy commodity prices, but we fail to find strong spillovers from oil to non-oil commodity prices or an impact of the interest rate. In addition, we find that individual commodity prices are affected by common trends captured by the food and metals factors.

COMMODITY PRICES REVISITED

Empirical models of commodity prices are potentially important aids to decision-makers, especially as the economy has grown more complex. A typical time series of commodity prices exhibits positive autocorrelation, occasional spikes, and random variability, and conceptual models have been developed to explain this behavior. But, the leap from theory to empirical applications is large because of model specification and data quality problems. When modeling price expectations, for example, should a price series be deflated and if so, by what deflator? The choice can have a large effect on empirical results. Nonetheless, it is possible in some applications to obtain relatively stable-estimates of structural parameters that are useful for addressing specific problems. This may not happen often, however, because the incentives in academia do not encourage rigorous, in-depth appraisals of empirical results.Demand and Price Analysis,

Agricultural Policy: High Commodity and Input Prices

Because of high commodity prices, beginning in 2006, subsidies to farmers in the United States, the European Union, and Canada have been reduced significantly. However, significant losses have been experienced by the red meat sector, along with escalating food prices. Because of rising input costs, the “farm boom†may not be as great as first thought. Ethanol made from corn and country-of-origin labeling cloud the U.S. policy scene. Higher commodity prices have caused some countries to lower tariff and non-tariff barriers, resulting in freer commodity trade worldwide. Policymakers should attempt to make these trade-barrier cuts permanent and should rethink current policy legislation to deal with the possibility of a collapse of world commodity markets. Agricultural commodity prices have dropped significantly since early 2008.agricultural policy, high commodity prices, input prices, Agricultural and Food Policy,

Global Commodity Markets - Price Volatility and Financialisation

A significant increase in the level and volatility of many commodity prices over the past decade has led to a debate about what has driven these developments. A particular focus has been on the extent to which they have been driven by increased financial investment in commodity derivatives markets. This article examines the factors behind the increase in the level and volatility of commodity prices. The available evidence suggests that while financial investors can affect the short-run price dynamics for some commodities, the level and volatility of commodity prices appear to be primarily determined by fundamental factors.Commodity; Commodities; Commodity prices; Commodity price; volatility; Speculation; Oil prices; Financialisation; Financialization; G-20; G20; CRB; Derivatives

Linkages among precious metals commodity futures prices: evidence from Tokyo

We investigate whether long-term co-movements among the prices of precious metals commodity futures contracts can be observed. The past literature on agricultural commodity futures prices obtains the mixed results. We find that there is no long-term interdependence among the prices of the four non-agricultural commodity products traded at the Tokyo Commodity Exchange. The finding provides new evidence against interdependence of commodity futures prices.Commodity Futures, Futures Pricing, Futures Market, Natural Resources

COST PASS-THROUGH IN THE U.S. COFFEE INDUSTRY

A rich data set of coffee prices and costs was used to determine to what extent changes in commodity costs affect manufacturer and retail prices. On average, a 10-cent increase in the cost of a pound of green coffee beans in a given quarter results in a 2-cent increase in manufacturer and retail prices in that quarter. If a cost change persists for several quarters, it will be incorporated into manufacturer prices approximately cent-forcent with the commodity-cost change. Given the substantial fixed costs and markups involved in coffee manufacturing, this translates into about a 3-percent change in retail prices for a 10-percent change in commodity prices. We do not find robust evidence that coffee prices respond more to increases than to decreases in costs.cost pass-through, retail prices, manufacturer prices, commodity costs, coffee, Demand and Price Analysis,
