Overview
The ERS data set contains annual and monthly data for exchange rates
important to U.S. agriculture. It includes both nominal and real
exchange rates for 80 countries (plus the
European Union) as well as real trade-weighted exchange rate indexes
for many commodities and aggregations.
All series are updated every other month. Data series start at the
beginning of 1970 and run to the last available current monthly
information, which is typically 2 months behind the current date.
Feature
The Agriculture Baseline Briefing Room
provides analysis of USDA's long-term projections for U.S. and global
agriculture.

agricultural exchange rate data set.
Data Files
The data set is divided into country and commodity spreadsheets.
Each component of the data set is available as an Excel spreadsheet.
Exchange rates are expressed in foreign currency per U.S. dollar.

Commodity Spreadsheets
The commodity trade-weighted exchange rates are divided into three component
sets of weights based on: U.S. exports, other countries' agricultural exports
to
the world, and countries which export agricultural products to the
United States.
Exchange Rate Weights
Weights are average dollar shares
of U.S. exports, other countries' exports to the world, and U.S.
imports for the relevant commodity or commodity aggregation between
1998-2000.
- Exchange Rate Weights includes
annual average trade-weighted exchange rate indexes for the 54 monthly
commodity indexes.
Release Date
The data are updated every other month around the middle of the
month.
Data Set Revision
The Agricultural Exchange Rate Data Set was revised in June 2000.
The revision involved two major components. First, the country list
was expanded from 63 to 80 countries. Some countries (e.g. the Leeward
and Windward Islands) were dropped because they were not considered
to be serious trading partners. Many Central and South American
countries were added because it was felt that these regions were
underrepresented in the previous country set. Some European and
African countries were also added. The countries were also reorganized
by region instead of alphabetically.
Many new exchange rates were also added under the existing markets
and competitors areas, and a new area was added for suppliers. All
exchange rates were recalculated back to January 1970. Finally,
the weights were revised from a 1990 base to a 1994-96 base. In
December 2002, the base was further revised to 1998-2000. The composition
of trade has changed significantly since the 1990s, and different
countries are weighted more or less significantly in the revised
weighting scheme. For example, the relative importance of Canada
and Mexico has increased while that of Europe has decreased.

upland cotton), and livestock (beef, pork, poultry and eggs,
and
dairy).
