USD/JPY has extended rally, presently at 89.90. As well as the aforementioned US investment bank buying interest, sources also note sovereign buying interest.

JPY will have been undermined a little by Fitch comment that they could downgrade Japan if government bond issuance rises rapidly. The ratings agency seems to be enjoying its moment in the limelight.

Psychological 90.00 level looms, while technical resistance next at 90.15/20. Probably stops above both levels.
