The dollar has long been strong. In mid-2015 the situation began to change when the global economy to realize all the negative aspects of superstrong USD - Materials AMarkets.
Then the "big twenty" decided to bring down the dollar in March 2016, to rescue China from the consequences of a stronger currency and commodity markets (as well as lenders to extend loans to producers of raw materials).Since then, the dollar regained its footing, which led to the logical problems in the risky asset markets, raw materials, as well as segments that are dependent on Chinese exports. The global forex market is no absolute winners or losers. All sides of the process are constantly changing places, looking at what angle to look at the situation. Europe and Japan is beneficial the strong USD, the euro and the yen weakened. However, a strong dollar is unpleasant to China, which carries a legitimate loss. Commodities lose if the dollar rises, however, the American consumer can no longer buy at a strong USD. As a reserve currency, the dollar plays local and international role. Each role of its priorities. They may interfere with each other on certain items.
Global Strategy for the US Federal Reserve - is still weakening and USD interest rates for export stimulation.But here, once there is a negative point - investors are beginning to withdraw capital from the economy with a weak dollar. Since the main purpose of investment capital - to get to the high interest rates and a strong currency terms, to preserve its value and get a good return over time. The outflow of capital reduces the value of the dollar, reducing the purchasing power of Americans and all those who have assets in dollars. As a result of capital flight from dollar assets is enhanced - it becomes an avalanche. As can be seen, each of the global process is the reverse side. The gain on the one hand - it is losing the other.
