The strongest and weakest currencies as NA traders enter for the trading day

The EUR is the strongest. The JPY is the weakest.
The EUR took a collective breathe on the back of Macron/LePen matchup for the 2nd round. That makes the EUR the runaway favorite.  Over on the weak side, the JPY is "flight out of the safety of the JPY" trade. Stocks are up, bond yields are up, and gold is down and that has been spelling lower JPY.  If you add up the % changes of the major currencies, the JPY sum is actually larger than the EUR’s sum.
