Big break of the descending trendline from April. This is what the 30yr yield did just before they sold off. This is positive for USDJPY.
USDJPY 4hr chart, back in the wedge it broke from yesterday, if it keeps support at 81.00 this could be a good countertrend swing. If it stays positive this week then weekly will be a good hammer candle too. Obvious first resistance is at 83.00.
