Value of the dollar

Hi, in an Aug. 8, 2007 article by Jessic Hupp of www.currencytrading.net She explains 50 factors that affect the value of the US. Dollar under these subheadings:  Balance of Trade and Investment, Politics, Other Countries, Entitlements, Economic Theories, Interest Rates, the American Consumers, Housing, Industrial and Economical Indicators, U.S. Capital Markets, The Economy, Weather, and Inflation.  An except from the article regarding the dollar in other countries is as follows: 

Other countries

Political impact on the dollar does not originate entirely from the US; it can come from all over the world. Trade, conflict, consumption, and other issues can affect the dollar from outside our country.

1. Turmoil in other countries: When other countries are in a state of conflict, their respective currencies may be perceived as unstable. In this case, investors may flock to the dollar because it is considered a safer bet.
2. Stability in other countries: On the other hand, if other countries are consistent in their policy-making as well as politically and economically stable, the dollar may weaken because investors have more confidence in these alternative currencies. They’ll see them as less risky and diversify into non-dollar denominated assets.
3. A change in foreign reserves: The USD benefits strongly from being the world’s reserve currency. Most central banks hold more dollars than any other currency, but the dollar faces problems when they decide to diversify their currency investments. This could mean that they sell dollars, or simply just stop buying more. This is especially damaging when a large purchaser like China decides to stop adding to its foreign reserves.
4. A strengthening Euro: The dollar faces competition from the rising Euro. It’s an attractive alternative to the dollar when investors choose to diversify or if the dollar becomes unstable.
5. Acceptance of oil in dollars: As long as the majority of world oil contracts are settled in USD, other countries have to use the currency. This increases demand for the dollar and therefore, its value. Additionally, most oil exporters hold a significant portion of their oil proceeds in dollars.
6. Strong foreign economies: If other countries’ economies are booming, the dollar may fall because it will become a relatively less attractive place to invest.
