In the post below I look at the arguments for JPY weakness in the weeks and months ahead.
A combination of elevated risk aversion and a narrowing US / Japan yield differential have been the major contributors to the strengthening in the JPY over January resulting in safe haven JPY demand and repatriation flows. The sensitivity of the JPY to both factors has been especially strong and it will require a reversal of one if not both of these to spur another wave of JPY selling.
Improving risk appetite required
If there is not a metamorphosis of the current bout of pressure into a full blown crisis as seems likely, risk appetite will improve and the upward pressure on the JPY will abate. Any improvement in risk appetite will however, be gradual and prone to volatility, especially in an environment of Fed tapering. It may therefore require more than simply improving risk appetite to weaken the JPY anew.
Japanese equity performance will be eyed
Of course associated with any improvement in risk appetite has to be a reversal of the recent negative performance of Japanese equities. Although Japanese equities will continue to be hostage to the fortunes of global risk sentiment, assuming that “Abenomics” continues to deliver results and growth in Japan continues to pick up (our forecast this year is 2% YoY GDP growth) further fallout in the Japanese equity market may be limited.
Flows will need to reverse
Over the past several weeks Japan has registered net inflows of capital in large part due to repatriation by Japanese investors. JPY has faced upward pressure from such inflows over recent weeks. Looking ahead assuming that risk appetite improves and US yields increase net capital outflows are expected to resume, which will put further downward pressure on the JPY.
Yield differentials will be particularly important
The extra dose of JPY pressure and important determinant of renewed weakness will be a re-widening of the US / Japan real yield differential. Eventually US bond yields will resume their ascent, driving the yield differential with Japan wider, and putting upward pressure on USD/JPY. The same argument will apply for EUR/JPY, albeit to a lesser degree.
Speculation positioning more balanced
The recent short covering rally has likely resulted in a market more evenly balanced in terms of positioning, providing a solid footing for the next leg lower in JPY. Indeed, compared to the three month average, JPY positioning has bounced back and is susceptible to a rebuilding of JPY shorts over coming weeks, driving the JPY lower.
Model points to renewed JPY weakness
Combining the factors above (except positioning) and adding in forecasts for US bond yields, risk aversion and conservative estimates for a recovery in Japanese equity markets over coming months, my quantitative model for USD/JPY highlights the prospects of a major rebound in the currency pair.
