Foreign exchange traders face their worst year since 2005, and the U.S. government shutdown only makes matters worse.

The record-long US government shutdown is leaving foreign exchange traders in their worst year in decades, as the lack of economic data shrouds the outlook for the US dollar. According to the BarclayHedge index, foreign exchange investors are expected to have their worst performance since 2005. Even before the data vacuum, Wall Street was feeling the pressure - companies like Goldman Sachs, Morgan Stanley, and Bank of New York Mellon have all reported a decline in foreign exchange trading revenue for the last quarter.
