The USDJPY reversed strongly from the 137 round number resistance level, trading lower through the session on Friday, ending the week at the 135.80 price area.
This move lower, as we know was due to the weakness in the DXY, hence, if the weakness continues, the USDJPY could continue trading lower, down to retest the 135.35 key support level.
The USDJPY could see significant volatility this week, given that the JGB 10yr yield had recently breached the 0.5% ceiling and the BoJ monetary policy statement is due to be released (and it is Kuroda's last meeting as Governor).
If the price breaks below the immediate support level, the USDJPY could see significant downside potential, with the next key support level at the round number level of 134.
