(2/23/2015) A rare issue on which the two parties in the US Congress agree is the problem of “currency manipulation,” especially on the part of China. Perhaps spurred by the 2014 appreciation of the dollar and the first signs of a resulting loss of American net exports, Congress is once again considering legislation to attack currencies that are seen as unfairly undervalued. The proposed measures include the threat of countervailing duties against imports from offending countries, although that would be inconsistent with international trading rules.
