Does Speculation Drive Commodity Prices? Evidence from the Market for Corn


Book Description

Seminar paper from the year 2020 in the subject Economics - Finance, grade: 1,0, University of Münster, language: English, abstract: This seminar paper reviews the literature on futures markets as well as the recent food crisis and presents an empirical investigation of the influence of (index) speculation on the corn price. My findings are in line with most of the other empirical conclusions that, rather than speculation, factors from the real and monetary economy played a role in the spike of commodity prices. For centuries, corn has been one of the most produced crops in the world, used to feed people, livestock and machines. During the last quarter of the twentieth-century, world food prices declined by more than 50 percent, thereby improving the nourishment of people all over the world. However, this extensive decline also raised calls for protectionist policies, aimed at defending the welfare of commodity producers. Starting in the early 2000s, all classes of commodities have experienced hefty price increases. The price for corn increased by more than 250 percent in roughly three years (2005-2008). The resulting food crisis devastated low-income communities around the globe, with the already large part of their income they spent on food becoming even more substantial, causing hunger and malnutrition. While a variety of explanations for this crisis have been offered, some were quick to blame excessive (index) speculation.







The Art Of Speculation


Book Description

Philip L. Carret (1896-1998) was a famed investor and founder of The Pioneer Fund (Fidelity Mutual Trust), one of the first Mutual Funds in the United States. A former Barron’s reporter and WWI aviator, Carret launched the Mutual Trust in 1928 after managing money for his friends and family. The initial effort evolved into Pioneer Investments. He ran the fund for 55 years, during which an investment of $10,000 became $8 million. Warren Buffett said of him that he had “the best long term investment record of anyone I know” He is most famous for the long successful track record he achieved investing in Common Stocks and for being one of Warren Buffett’s role models. This book comprises a series of articles written for Barron’s and published in book form in 1930.—Print Ed.










The Impact of Speculation on Commodity Futures - A Review of the Findings of 100 Empirical Studies


Book Description

There are numerous empirical studies on the impact of speculation on commodity futures prices. The papers strongly differ in terms of the focus variable (e.g. price, volatility, spillover effects) of speculative effects, the speculation measure used, and their methodological sophistication and quality. We review and evaluate the methodology and results of 100 papers which have been published (or are at least frequently quoted) on this subject over the past decade. While the overall picture indicates that the number of studies which report reinforcing and weakening effects is about the same, the results shift in favor of finding (clear or mixed) weakening effects if studies use direct measures of speculation.




Oil Price Volatility and the Role of Speculation


Book Description

How much does speculation contribute to oil price volatility? We revisit this contentious question by estimating a sign-restricted structural vector autoregression (SVAR). First, using a simple storage model, we show that revisions to expectations regarding oil market fundamentals and the effect of mispricing in oil derivative markets can be observationally equivalent in a SVAR model of the world oil market à la Kilian and Murphy (2013), since both imply a positive co-movement of oil prices and inventories. Second, we impose additional restrictions on the set of admissible models embodying the assumption that the impact from noise trading shocks in oil derivative markets is temporary. Our additional restrictions effectively put a bound on the contribution of speculation to short-term oil price volatility (lying between 3 and 22 percent). This estimated short-run impact is smaller than that of flow demand shocks but possibly larger than that of flow supply shocks.




Does Futures Speculation Destabilize Commodity Markets?


Book Description

This paper examines how speculative futures trading affects commodity markets in terms of price impacts, volatility, and market quality. Contrary to the popular belief that speculators are responsible for the recent commodity price fluctuation, my analysis finds no evidence that speculators destabilize the spot market. Instead, speculators contribute to lower volatility and enhanced market quality. More importantly, the empirical results provide strong evidence that speculators either have no effect or dampen prices during periods of large price movement. My findings suggest speculators have had a significant, and in fact positive, influence on the commodity market during the recent "financialization" period, implying that restricting speculative trading in the futures market is not an efficient way to stabilize the commodity market.
