The short-end of the US Treasury yield curve is very influential on USD/JPY. Higher yields help bolster the dollar, generally speaking. Yields have firmed toward the top of their recent range arounf the 0.95% level and a break to the topside should help support the greenback.
Offers are seen in the 91.00 from Japanese exporters. We topped out yesterday at 90.83. We trade now at 90.60.
