No significant option expiries were reported in USD/CAD at the 10 am ET cut but the pair spiked higher at the cut and then sold

In any case, USD/CAD bulls weren't quite ready to take a crack at the crisis high of 1.3065. Oil prices bounced from $50.13 and it looks like oil breaking below $50 and USD/CAD above 1.3065 is the same trade.
Last at 1.2969 -- the lowest in US trading.
