Since, 1971, the US Dollar has been through cycles, rather long cycles, 10, 7, 10 year cycles where it went down steadily and two long cycles were it rose steadily 7, 9 years.
1968-78, 1985-92, 2001-2011 down cycle
1978-1985, 1992-2001 up cycle
I believe we are entering another 7 - 10 year uptrend, because the Yen and the Euro are tired of being so strong for so long, they need to devalue their currency to get their economies going, too many people out of work and they need to create real jobs and investment, not bubbles.
The FED needs to unwind monetary distortions that they did to save the big banks at the expense of the people who save and invest in CD's and bank account.
Look for a strong and steady US Dollar and capital flows should swing wildly, rising inflation and interest rates and forced tightening by the FED. A strong dollar will lead to lower commodity prices (gold, copper, oil, etc) and higher interest rates.
VIVA HIGH INTEREST RATES, lets get the capital flows moving.
