And back down USDJPY goes as N. Korea rejects diplomacy for now - CNN

Some of the run up remains

There is another report from CNN saying N. Korea has rejected diplomacy for now.

So the USDJPY has rotated back lower. Some of the run up remains though. The pair remains above the NY/London session highs (red line).

The pair had been in a 22 pip trading range in the NY/London session before the break higher. So perhaps the market is just tired of being in that rut. We will see, but momentum higher has been dealt a blow on the headline.
