Although the greenback extended last Friday's rebound to as high as 90.47 on active cross unwinding in jpy, price retreated strongly to 89.62 in Asian morning, suggesting the corrective upmove from last week's 8-1/2 month low of 88.01 has possibly made a temporary top there and consolidation with mild downside bias would be seen for a drop to 89.24/30, however, pivotal support at 88.65 should remain intact.  
On the upside, a breach of 90.47 would bring stronger retracement of recent decline to 90.82 but renewed selling should emerge well below 91.59/63 resistance area.
