USD/JPY Drifts into 145-150 Range: Assessing Alarm Signals and Market Dynamics

JPY: Where is the alarm?

USD/JPY has quietly drifted into the 145-150 intervention zone without triggering many alarm bells in Tokyo. One difference between now and the intervention period last September and October is that FX conditions are much more orderly. For example, one month USD/JPY implied volatility is trading near 9% today versus levels in the 14-15% region during Japanese FX intervention last year.  At the same time, there is no sense of a 'sell Japan' mentality emerging, and Japanese authorities may actually tolerate a softer yen given the deflationary forces emerging from China and the weak export markets in Asia and Europe.

Unless we see some financial shock that triggers an unwind of the carry trade, it looks as though USD/JPY can hang around this 145/150 region longer than we had originally forecast. A decisive turn lower may have to wait until the late September and October period when more evidence of a US slowdown should have emerged and speculation will be growing over a Bank of Japan policy change at the meeting in late October.
