USD/JPY rebounds from session lows, but can it hold the recovery?

Earlier this morning, as US yields slipped back quite markedly, the USD/JPY took a hit. The dollar had closed in the US on Friday, at 154.78. It got crunched lower, to 153.55 and that slide helped the EUR/USD and GBP/USD to bounce. The US 10 year yield fell back to 4.34%. It had closed on Friday, at around 4.42%. That yield has not bounced much yet today, but the USD/JPY has managed to rebound off the lows, lifting back to 154.40 a moment ago. That is possibly quite surprising, but we shall have to see how the price action unfolds from here on today. The first support of note (which was taken out earlier of course) is the 21 day moving average. That is currently at 153.89, but owing to the volatile price action, it is chopping and changing all the time. On the topside, 155 looks like a level of note again today. The USD/JPY is currently trading at 154.25
