U6 Underemployment Rate
The U6 or underemployment rate, released by the US Bureau of Labor Statistics, considers anyone who has looked for a job within a year and desires to work as unemployed. It adds those workers who are part-time purely for economic reasons. Its wider and more realistic criteria are considered by many economists. Many analysts consider it a more accurate measure of unemployment.
Usually, a higher rate is seen in recessionary economies, while on the contrary, a growing economy sees its underemployment rate decreasing. Therefore, a decrease of the figure is seen as positive (or bullish) for the USD, while an increase is seen as negative (or bearish). The number can't determinate just by itself how the markets move, as it depends on the headline reading, the Nonfarm Payrolls.
