Final answer:
A decrease in the USD-CAD exchange rate means that the Canadian dollar is worth fewer American dollars, which can benefit Canadian exporters but increase costs for Canadian consumers. Historical fluctuations reveal that exchange rates affect trade significantly, with changes in currency values directly impacting the economic activities between Canada and the United States.
Step-by-step explanation:
A decrease in the USD-CAD exchange rate indicates that the Canadian dollar is worth less in terms of American dollars. This situation has varying impacts on the Canadian economy. On one hand, a weaker Canadian dollar can make Canadian exports more competitive on the international market, potentially leading to an increase in demand for Canadian goods abroad, which can boost the export sector of the economy.
On the other hand, Canadian consumers may face higher prices for imported goods, as a lower exchange rate means that more Canadian dollars are needed to buy the same amount of foreign products. This could lead to an increase in inflation and reduce the purchasing power of Canadian consumers.
The historical fluctuations of the exchange rate between the USD and CAD show that the relationship between the two currencies directly affects trade and economic activity. For instance, when the U.S. dollar appreciates, Canadian goods become less expensive for American consumers, which usually results in a boost for Canadian exporters. Conversely, when the Canadian dollar appreciates, Canadian goods become more expensive in the U.S., and America may import less from Canada, leading to a decline in Canadian exports.
The exchange rate movements since 1980 highlight the substantial and sometimes sharp changes that can occur, reflecting the dynamic nature of economic relationships between neighboring countries.
