Chart Of The Day: Trading The Yen's Surprising Decline

 | Jul 16, 2018 10:01AM ET

The yen slipped 1.75 percent last week, its worst decline in 10 months. Why would Japan's currency be edging lower, even against a weaker dollar? While no obvious fundamentals appear to be the significant driver, perhaps a bit of underlying market psychology explains the transition in the supply-demand balance.

Could the USD/JPY slide underscore a shift in investor sentiment, away from global trade worries, back into risk assets? Conceivably the growing interest rate differential, favoring the dollar versus the yen, might be seen as a catalyst for the yen's downward move, whose non-existent yield risks now overshadow its haven status.

However, the fact that the widening rate gap between the US and Japan didn't just take shape last week seems to point to the fact that there isn't a single key fundamental trigger that can independently explain the price move. Perhaps there's a perfect storm of political and economic events now weighing on the Japanese currency.
