We're seeing a strong surge in AUDUSD and NZDJPY 26 July 2015
Looks like traders may have been short and caught on these two ccys. Ordinarily the yen demand/Aso comments would have knocked them lower through the JPY crosses but lack of further downside momentum appears to have triggered a run for cover.
AUDUSD currently 0.7518 after 0.7536 from 0.7490 in a rush while NZDUSD has jumped from 0.7015 to 0.7058. USDJPY 104.38 from lows of 104.27
No related news out that I can see to trigger the move so short-covering my guess at this point with a bit of USD supply generally.
