As noted earlier, a change in the exchange rate can, in the short run, affect the demand for and supply of commodities, and the competitiveness of US agriculture. When the US dollar strengthens or gains in value, it causes importers to pay more for the US dollar to buy US commodities.
This article will examine these questions. While the question of the effects of the devaluation of the dollar against other currencies is important, that topic is beyond the scope of this article. The exchange rate between the dollar and the euro is set by supply and demand. That is, the exchange rate âfloatsâ or adjusts to the demand for (and supply of) dollars versus euros.
