It may not be moving all that much but USD/JPY is seeing significant turnover in the 84.60/90 range we’ve seen during NY trade. Japanese exporters remain the dominant sellers with some options-related selling mixed in as well.
If you bought USD/JPY for the excitement, let me suggest another line of work…It’s a marathon, not a sprint. Above 85.00 or so, the pace might pick up, though…
