Despite cross-inspired rally to 87.54 in early Asian session yesterday (following Bank of Japan's announcement of an emergency meeting), dollar's subsequent retreat from there suggests the erratic rise from 84.82 has possibly formed a top and consolidation with downside bias is seen for weakness towards support at 85.86.  
Above aforesaid resistance at 87.54 would abort this near term bearish scenario and risk another corrective rise towards 88.01 (previous support).
