Explanation Factor 1 is correct: The current account is the balance of trade between a country and its trading partners, reflecting all payments between countries for goods, services, interest, and dividends. A deficit in the current account shows the country is spending more on foreign trade than it is earning, and that it is borrowing capital from foreign sources to make up the deficit. In other words, the country requires more foreign currency than it receives through sales of exports, and it supplies more of its own currency than foreigners demand for its products. The excess demand for foreign currency lowers the country's exchange rate until domestic goods and services are cheap enough for foreigners, and foreign assets are too expensive to generate sales for domestic interests.
Factor 2 is correct: High levels of public debt make a country less attractive to foreign investors due to concerns about inflation and potential default. If the government resorts to printing money or borrowing from foreign sources, it increases inflationary pressure and lowers investor confidence. As a result, the value of the domestic currency may decline.
Factor 3 is correct: A country with a relatively low inflation rate usually experiences a higher currency value, as its purchasing power increases relative to other currencies. During the last half of the 20th century, the countries with low inflation included Japan, Germany, and Switzerland, while the U.S. and Canada achieved low inflation only later.
Countries experiencing higher inflation typically see depreciation in their currency versus the currencies of their trading partners. This is also usually accompanied by higher interest rates.
