As noted last week, the break of 147.61 exposed 145.90 as the next target.
Another test just below 146.50 suggests this will be the pivotal level determining whether there will be a run at 145.90 and then 145.
As also noted (when USDJPY traded below 148), expect a limited USDJPY upside ahead of the March 18-19 BoJ meeting where there is a risk of the neverending story of a rate hike to bring Japan out of negative interest rates finally reaching a conclusion.
