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.
The currency exchange rate is the rate at which one currency can be exchanged for another. It is always quoted in pairs like the EUR/USD (the Euro and the US Dollar). Exchange rates fluctuate based on economic factors like inflation, industrial production and geopolitical events.
