The U.S. dollar is showing weakness amid tempered optimism about improving trade relations between the U.S. and China. Currency markets are reacting to the general uncertainty related to the further course of negotiations and possible economic consequences. As a result, the dollar has weakened against defensive currencies including the yen and Swiss franc, and has also lost ground to the euro and pound. The focus is on the upcoming data on inflation and labor market in the U.S. In addition, the growth of food prices in the UK reached the maximum for the year.All these factors contribute to the increase in quotations of the pair GBP/USD, which failed to consolidate under the mark 1.3200. The price is again testing the border of the resistance zone near the level of 1.3400. If it is overcome, the next resistance may be met closer to 1.3550.
