31. Too Much of a Good Thing? Speculative Effects on Commodity Futures Curves

Abstract:
The increasing inflow of institutional investors replicating broad based indices into commodity futures markets has been linked to excessive calendar spreads and anomalies in futures curves. At the same time, these investors have been welcomed as liquidity providers. This paper hypothesises that this apparent dissent can be reconciled by considering the relative size of index positions to hedging positions, rather than the presence of index traders alone. The hypothesis is tested empirically for three soft commodity markets: cocoa, coffee, and cotton. By use of factor decomposition, the paper shows empirically that (a) index and hedging positions have inverse and offsetting effects on futures curves, and (b) index positions, net of hedging positions, are associated with upward sloping and peaked futures curves and occasionally wave-like shapes linked to roll-effects. The paper concludes that index traders are welcomed liquidity providers but can become ‘too much of a good thing’ if exceeding hedgers’ demand for counterparty.

32. Price Discovery in Commodity Futures and Cash Markets with Heterogenous Agents

Author:

Working Paper
Institution:
School of Oriental and African Studies - University of London
Abstract:
The paper develops a price discovery model for commodity futures markets that accounts for two forms of limits to arbitrage caused by transaction costs and noise trader risk. Four market regimes are identified: (1) effective arbitrage, (2) transaction costs but no noise trader risk, (3) no transaction costs but noise trader risk and (4) both transaction costs and noise trader risk. It is shown that commodity prices are driven by both market fundamentals and speculative trader positions under the latter two regimes. Further, speculative effects spill over to the cash market under regime (3) but are confined to the futures market under regime (4). The model is empirically tested using data from six grain and soft commodity markets. While regime (4) is rare and short lived, regime (3) with some noise trader risk and varying elasticity of arbitrage prevails

33. How to Cope with Volatile Commodity Export Prices: Four Proposals

Author:
Jeffrey Frankel

Content Type:
Working Paper
Institution:
The John F. Kennedy School of Government at Harvard University
Abstract:
Countries that specialize in commodities have in recent years been hit by high volatility in world prices for their exports. This paper suggests four ways that commodity-exporters can make themselves less vulnerable. (1) Option contracts can be used to hedge against short-term declines in the commodity price without giving up the upside, as Mexico has shown. (2) Commodity-linked bonds can hedge longer-term risk, and often have a natural ultimate counter-party in multinational corporations that depend on the commodity as an input. (3) The well-documented pro-cyclicality of fiscal policy among commodity exporters can be reduced by insulating official forecasters against an optimism bias, as Chile has shown. (4) Monetary policy can be made automatically more counter-cyclical, judged by the criterion of currency appreciation in reaction to positive terms-of-trade shocks, under either of two regimes: peggers can add the export commodity to a currency basket (CCB, for “Currency-plus-Commodity Basket”) and others can target Nominal Income instead of the CPI.

34. The Currency-Plus-Commodity Basket: A Proposal for Exchange Rates in Oil-Exporting Countries to Accommodate Trade Shocks Automatically

Author:

Content Type:
Working Paper
Institution:

Abstract:
The paper proposes an exchange rate regime for oil-exporting countries. The goal is to achieve the best of both flexible and fixed exchange rates. The arrangement is designed to deliver monetary policy that counteracts rather than exacerbates the effects of swings in the oil market, while yet offering the day-to-day transparency and predictability of a currency peg. The proposal is to peg the national currency to a basket, but a basket that includes not only the currencies of major trading partners (in particular, the dollar and the euro), but also the export commodity (oil). The plan is called Currency-plus-Commodity Basket (CCB). The paper begins by fleshing out the need for an innovative arrangement that allows accommodation to trade shocks. The analysis provides evidence from six Gulf countries that periods when their currencies were “undervalued”, in the sense that the actual foreign exchange value lay below what it would have been under the CCB proposal, were periods of overheating as reflected in high inflation and of external imbalance as reflected in high balance of payments surpluses. Conversely, periods when the currencies were “overvalued,” in the sense that their foreign exchange value lay above what it would have been under CCB, featured unusually low inflation and low balance of payments. These results are suggestive of the implication that the economy would have been more stable under CCB. The last section of the paper offers a practical blueprint for detailed implementation of the proposal.

Abstract:
India’s exports have declined for six consecutive monthssince December 2014 with an average decline of 13.85% yoy. The decline was broad-based. Even exports of Manufactured goods trended lower during this time and failed to compensate for the fall in nominal value of commodity exports, which declined due to a huge erosion of global commodity and oil prices. India’s exports seem to have become more reliant on global commodity prices in recent years. In line with global crude oil prices, India’s monthly petroleum exports that peaked in July’14 at $7 billion shrunk to mere $2.4 billion in May 2015, declining at an average of 52% since the start of the year. Iron ore exports having peaked at $509.5 million in December 2011 moved from $129.5 million in April 2014 to $10 million in May 2015. It is instructive to take a longer term perspective of export performance (Please see Chart I below). Average export growth hasremained almoststagnantsince January 2012 after a sharp bounce back from the collapse in the first and second quarters of 2009, induced by the global financial crisis. Export growth since October 2011 (50 months) is much lower than the robust 20% average clocked during the seven year period of April 2002- March 2009. (marginally lower than the 23% rate of growth assumed for the five year period of 2015-16 to 2020-21 in the Foreign Trade Policy announced in early 2015).

Abstract:
There is a link between primary commodity export prices and economic performance. Many African economies are primary commodities export biased, often in few primary commodities. Previous studies focus on the impact of commodity prices on growth in Africa with little attention paid to different primary commodities and level of diversification in primary commodities export. This study, investigates the effect of primary commodity prices on the long-run growth of 24 primary commodities-based African economies; by commodity types and level of diversification in primary commodities exports.

38. Moving to the Adjacent Possible: Discovering Paths for Export Diversification in Rwanda

Abstract:
How can Rwanda, which currently has one of the lowest levels of income and exports per capita in the world, grow and diversify its economy in presence of significant constraints? We analyze Rwanda's historical growth and trade performance and find that Rwanda's high transportation costs and limited productive knowledge have held back greater export development and have resulted in excessive rural density. Three basic commodities – coffee, tea, and tin – made up more than 80 percent of the country's exports through its history and still drive the bulk of export growth today. Given Rwanda’s high population density and associated land scarcity, these traditional exports cannot create enough jobs for its growing population, or sustainably drive future growth. Rwanda needs new, scalable activities in urban areas. In this report, we identify a strategy for greater diversification of exports in Rwanda that circumvents the key constraints and is separately tailored for regional and global export destinations. Our results identify more than 100 tradable products that lie at Rwanda's knowledge frontier, are not intensive in Rwanda's scarce resources, and economize on transportation costs. Our analysis produces a vision of a more diversified Rwanda, which can be used as a guide for investment promotion decisions. We illustrate an approach that can be applied to other settings in order to identify opportunities for export diversification that take seriously local constraints and external market opportunities.

39. Price Non-Convergence in Commodities: A Case Study of the Wheat Conundrum

Author:
Sophie van Huellen
Publication Date:

Content Type:
Working Paper
Institution:
School of Oriental and African Studies - University of London
Abstract:
The close relationship between commodity future and cash prices is critical for the effectiveness of risk management and the functioning of price discovery. However, in recent years, commodity futures prices, across the board, have appeared increasingly detached from prices on physical markets. This paper argues that while various factors, identified in previous literature, which introduced limits to arbitrage have facilitated non-convergence, the actual extent of non-convergence in these markets is caused by essential differences in the mechanisms of price formation on physical and derivative markets. With reference to the particular case of the CBOT wheat market, the paper shows that the size of the spread between futures and cash prices can be theoretically and empirically linked to the increasing inflow of financial investment into commodity futures markets.

40. Commodity Price Movements in a General Equilibrium Model of Storage

Abstract:
We embed the canonical rational expectations competitive storage model into a general equilibrium framework thereby allowing the non-linear commodity price dynamics implied by the competitive storage model to interact with the broader macroeconomy. Our main result is that the endogenous movement in interest rates implied under general equilibrium enhances the effects of competitive storage on commodity prices. Compared to a model in which the real interest rate is fixed, we find that storage in general equilibrium leads to more persistence in commodity prices and somewhat lower volatility. Moreover, the frequency of stockouts is lower in general equilibrium. A key mechanism driving this result is a link between the ability of the household to smooth consumption over time and the level of storage in the stochasic equilibrium. Finally, the model is used to examine the macroeconomic effects of both biofuel subsidies for ethanol producers and, separately, subsidies designed to insulate households from high food prices.
