Japanese Yen bears have the upper hand; USD/JPY looks to reclaim 155.00 mark

The USD/JPY pair extends the overnight turnaround from over a one-week low. 

Fading safe-haven demand, along with the BoJ uncertainty, undermines the JPY. 

Bets for a less aggressive Fed easing lend some support to the USD and the pair.

The Japanese Yen (JPY) witnessed good two-way price moves on Tuesday and ended the day nearly unchanged against its American counterpart. Russia's announcement that it would lower its threshold for a nuclear strike drove some haven flows towards the JPY. The global flight to safety triggered a sharp fall in the US Treasury bond yields and further benefited the lower-yielding JPY, dragging the USD/JPY pair to over a one-week low, around the 153.30-153.25 region. The initial market reaction, however, faded rather quickly after comments from Russian and US officials helped ease market concerns about the onset of a full-blown nuclear war. 

Adding to this, the uncertainty over the timing of further monetary policy tightening by the Bank of Japan (BoJ) continued to undermine the JPY and, to a larger extent, overshadowed a modest US Dollar (USD) weakness. The JPY remains depressed following the release of Trade Balance data from Japan and assists the USD/JPY pair to build on the overnight solid intraday recovery of over 150 pips. That said, speculations that Japanese authorities might intervene in the FX market to prop up the domestic currency, coupled with geopolitical uncertainties, might hold back the JPY bears from placing aggressive bets and act as a headwind for the pair.
