The USD/JPY pair extended its intraday downfall and tumbled to fresh daily lows, around the 108.65 region during the early North American session. The pair failed to capitalize on its recent strong momentum to the highest level since March 26 and witnessed a sharp turnaround on the first day of a new trading week. The downfall, marking the USD/JPY pair's first day of a negative move in the previous five, lacked any obvious fundamental catalyst and could be solely attributed to some aggressive long-unwinding trade. As investors looked past Friday's blockbuster US monthly jobs report, the US dollar came under some renewed selling pressure and was seen as one of the key factors exerting some pressure on the USD/JPY pair. Meanwhile, the latest leg of a sudden drop over the past hour or so could further be attributed to a sharp intraday slide in the US Treasury bond yields.
