Food commodity price volatility
and food insecurity
Alexandros Sarris
Professor of economics, University of Athens,
Greece
Presentation at the International Conference on
Applied Biotechnology Research (ICABR) at
Ravello, Italy, on June 19, 2013
Plan of presentation
• Food commodity market volatility and why it matters
• Volatility risks faced by developing country food
importers
• Policies to manage price volatility
• Priorities for action by the international community
to assist developing countries to deal with continuing
food market volatility?
Global food commodity price volatility has been
unusually high in last five years.
World food commodity price index 1990-2011 (FAO)
Recent year wheat prices
Recent year maize prices
Oilseed prices 2005-2012

perspective (current prices)

Volatility matters for developing countries because of increasing
exposure.

Conceptual issues
• What matters for market participants is
uncertainty, namely ex-ante unpredictability and
not ex-post variability
• Risk is determined by exposure to uncertainty or
unpredictability
• Unpredictability not easily measured, while expost variability readily measured
• Impacts of volatility on DCs large at both micro
and macro levels because of large dependence on
primary food commodities and credit constraints
at both micro and macro levels
Has volatility increased? Annualized real historic volatility of
selected food commodities 1957-2010 (Source. Prakash 2011)

Has volatility increased? Implied price volatilities 1987-2010.
Proxies for unpredictability (Source: Prakash, 2011)
Volatility increases with high prices and low stocks

Volatility is positively correlated with open interest and volume of
trading in futures markets

Volatility estimates can vary widely. Estimates of
implied volatilities of wheat returns in CME versus
estimates using GARCH (correlation -0.03)
Today’s implied volatility can predict future actual volatility:
Dependent variable is actual price variance of maize futures in
Chicago in the two months after a given date

Staple food import risks in developing countries.
Macro issues
Transitory versus permanent external shocks
Uncertainty about external and internal factors
affecting food imports
Overall exposure to external food shocks and
degree of self sufficiency in staples (related to
biotechnology policies)
Possible impact of external and internal shocks
on domestic economy (rural versus urban)
Price transmission to domestic economy
Uncertainty of policy objectives and applied
policies
Structure of import trade (public versus private)
Staple food import risks in developing countries.
Micro issues
• Determining import requirements in any given year
• How to fulfil import requirements, namely through imports,
or by reductions in publicly or privately held stocks
• How to minimize overall cost of fulfilling import requirements,
given uncertainties in international prices and international
freight rates
• How to manage the risks of unanticipated cost overruns
• How to finance the transaction
• Counterparty risk of non-delivery of the agreed supplies
• Major factor in contract defaults is adverse price movements
that have not been hedged adequately by supplier
Policy options for food importing developing countries
to deal with external unpredictable food prices
• Trade policies (tariff changes, export taxes, restrictions)
not very effective
• Domestic taxation policies: not very effective
• Stock policies. Not effective unless there is control of
domestic market, and expensive
• Short term input and other production subsidies (may
work in some cases)
• Combine small scale market operations with effectively
targeted safety nets
• Import hedging to cover price risks
• Regional free trade may help diffuse impacts of external
and internal food shocks
• Coordination and information between private and
public sectors
Policies to assist developing food importing
countries to manage food market volatility and price
spikes
• Hedge food import risks with futures and
options
• Assure import financing
• Global safety nets
A system to ensure food imports in low income
countries net grain importing countries through a
dedicated Food Import Financing Facility
•The major problem faced by LDCs and NFIDCs during periods of
food import needs in excess of normal commercial imports, is
import financing for both private as well as parastatal entities
•Major reason for this is exposure limits of exporting country
private trade financing banks to various developing countries
•Need system that can provide guarantees to trade financing
banks to increase temporarily their exposure limits to grain
importing countries
Basic rationale and concept of a FIFF
• Purpose: To allow LDCs and NFIDCs to finance commercial food
imports in periods of excess import bills
• Problem to be dealt with: Credit and financing exposure ceilings
from developed country financing institutions to LDCs and NFIDCs
• Concept: Provide additional finance for commercial food imports in
excess of normal commercial food imports. In other words increase
risk bearing capacity of financial institutions financing food imports
• How: By inducing increases in credit ceilings and country exposures
under specific conditions, via a credible mechanism of
intermediation. This can be effected by sovereign loan guarantees
for the additional financing (only) by developed countries. Amounts
of guarantees would not surpass 10-15 percent of food import bills
of LIFDCs and would constitute a very small fraction of total debt
levels of major donors (less than 0.05 percent)

Global safety net. Proposal for a Global Financial
Food Reserve (GFFR)
Aim not to prevent spikes but to have some resources to assist quickly countries
most affected by price spike
Idea to establish a fund that would maintain a long position in basic commodities
in organized exchanges (much like existing financial commodity funds). This would
constitute a “virtual commodity reserve” to act as a dormant physical commodity
reserve.
When markets would go into a spike, as signaled by high probabilities of crossing
appropriate price bands, the GFFR could either take delivery or take monetary
profits. Such physical or financial resources could be utilized to assist, according to
pre-specified rules, highly affected countries to lessen the extra cost of food
commodity imports
Would act as part of a global safety net for low income net food importing
countries
Cost modest. Between 2006 and 2008 the total cereal import bill of LDCs increased
by roughly 20 percent or about 4 billion US$. If 10 percent of that could have been
considered as extraordinary cost of vulnerable poor countries that would be
compensated by developed countries as extraordinary aid under some global
safety net, then this would amount to 400 million US$.
If the fund before the crisis was of a size of 100 million US$, and it was all invested
in cereal stocks via long future positions, then at 5 percent margin it would have
commanded physical amounts, worth about 2 billion US$. The profits from a 20
percent increase in prices during the spike (and the actual increase during a spike
would have been much larger than this) would then have been around 400 million
US$
Measures to help needy food importing countries to manage
adverse impacts of price spikes
• Provide technical assistance to vulnerable food dependent developing
countries to analyze the food risks they face in the global food market
system, and assess country specific options to deal with them.
• Create a fund for the establishment of an internationally coordinated
“Global Financial Food Reserve” (or GFFR) of basic food commodities
• Create a dedicated Food Import Financing Facility (FIFF) to increase trade
finance for low income countries in times of food price spikes
• Support the establishment of a physical emergency reserve of about
300,000 to 500,000 tons of basic grains
• Assist food importing developing countries to develop market based
strategies to manage the risks of their food imports.
• Promote the organization of appropriate commodity exchanges in both
developed and developing countries
• Promote the establishment of international standardized commodity
contracts in basic food commodities
• Promote the creation of permanent global safety nets relating to food
price spikes
