In general we can conclude that mature and well established commodity futures markets exhibit co-movement with crude oil.

Biofuel policy has buffered the price relationship between corn and crude oil futures, be it until crude oil prices surpass a certain threshold level of 75$/barrel or higher.
Strong relationship between crude oil and corn markets on one side, and crude oil and ethanol on the other.

Ethanol and corn market prices – contrary to common belief – are not strongly bound by a long-run cointegrating relationship.

Ethanol mandated production --> corn markets more prone to volatility

Findings support the hypothesis that fluctuations in stock prices respond to movements of crude oil prices.

The degree and dimension of interaction varies substantially among countries, due to the country specific factors such as:
China’s remarkable economic growth; India’s regulated oil sector;
Russia’s oil reserves; and Brazil’s steady growth.
Crises, Crude oil and BRIC stock markets
Is there Co-Movement of Agricultural Commodities Futures Prices and Crude Oil?
Crude oil – corn – ethanol – nexus: a contextual approach
Indian sugar & Agricultural index futures are mainly affected by external (international) information-flows.

Agricultural futures linkages to global prices and crude oil: the case of India
Policy price interventions generate unintended outcomes such as the impaired functioning of the futures markets.

Traditional raw agricultural commodities are influenced by information related to energy and adjacent markets.

World commodity markets are responsive more than ever to information and experience price and volatility spillover effects among themselves.

Co-movement of commodity prices is a temporal (dynamic) concept and should be treated accordingly.

The complete process must be understood as the joining of the parts into a systematic chain and at every stage the whole process has to be kept in mind.
• Physical causes

• Macro-economic causes

• Intangible - behavioral causes

Information Flow Theory
Policy recommendations
Main priority: subsidizing education to improve and spread the knowledge around commodities futures markets outside the financial industry

Easily accessible quality information is required to facilitate the cooperatives and producer organizations in their price risk management strategies.

Next to price risk management --> Ameliorate current issues of market power asymmetry in agro-food sector, and unclear price transmission issues.
Initial concept of commodity futures:
--> need of farmers (or producers in general) and processors to protect themselves (i.e. hedge) against price risk

The reality: most market participants are from the financial sector
--> relatively little affinity with the physical side
99% Market Participants = Speculators
Decision = Buy - Sell - Hold (!?!)
No scarcity in futures markets
