Dollar's breach of 88.57 yesterday in part due to cross selling in yen signals recent erratic decline from 92.33 has resumed and a re-test of last month's low at 88.01 is seen, however, anticipated loss of downward momentum should keep price well above 87.40/50 and yield a corrective rebound later.  
On the upside, only a breach of resistance at 89.20 (this Monday's high) would signal temporary low has been formed and bring retracement to 89.50/60.
