• Federal Reserve sentiment has sent the Yen higher on US Dollar weakness.
• USD/JPY bears take control and eye the 127.50s. 
• A break of 129.50 opens the risk of a move to 130.00 and beyond. 

USD/JPY is offered by some 0.5% and has fallen from a high of 128.95 to a low of 128.17 in Asia so far. The bears are out in force following the Federal Reserve event. The central bank raised interest rates for the eighth time in a year but slowed its pace to a quarter of a point. As a consequence, the US Dollar fell and gathered pace on the downside due to the Federal Reserve's dovish tilt, despite inflation, ''running very hot''. 

Fed's chairman Jerome Powell threw in the towel with dovish comments such as, "We can now say for the first time that the disinflationary process has started".

This rhetoric will do the USD no favours and helps to provide a rather important floor underneath equity markets, supporting risk and propelling the Yen higher. ''The USD is stretched on a number of factors, but a catalyst to reverse it is more difficult to obtain than it was before this meeting,'' analysts at TD Securities argued.

''While re-acceleration risk (in growth/inflation) may be growing later this year in a soft landing outcome, the market is likely to push further USD weakness for the time being.''

Meanwhile, it is worth noting that the JPY net short positions dropped are at their lowest levels since March 202 as analysts at Rabobank acknowledged. ''Although speculators were disappointed that there was no tweak to the Bank of Japan’s Yield Curve Control policy at the January meeting, they are turning their attention to the next BoJ policy meeting in March.''

However, with US Dollar long positions having been off-loaded, speculators are more vulnerable to a positive outcome from this week's Nonfarm Payrolls
