On Friday of last week, the USDJPY was trending downward until around GMT 07:00, but it rebounded and continued to rise as the market waited for the U.S. employment statistics.
Those figures were announced at GMT 12:30. The unemployment rate in August improved as expected to 4.2% from 4.3% in July, but August nonfarm payrolls were weak, coming in at 142,000 versus a forecast of 165,000. The figure for the previous month was also revised down significantly from an increase of 114,000 to an increase of 89,000.
