USD/JPY faces downside risk as Wells Fargo flags BoJ September rate hike

The Japanese yen is in focus after Wells Fargo Chief Asia-Pacific Strategist Chidu Narayanan said on August 26 that the Bank of Japan may raise interest rates as soon as its September meeting. A hike would extend the BoJ's gradual policy normalization and narrow the still-wide US-Japan rate differential that has underpinned USD/JPY strength and carry-trade positioning. With the Federal Reserve seen at or near the end of its tightening cycle, a September BoJ move would shift the yield gap in the yen's favor, creating downside pressure on USD/JPY and on yen crosses such as EUR/JPY and GBP/JPY. Traders should monitor Tokyo CPI, wage growth data and BoJ official commentary for confirmation, as pricing for a September move remains incomplete and positioning is still net-short yen. A hawkish confirmation could trigger an accelerated unwind of short-yen trades and a sharp yen rally, while a BoJ hold would likely see USD/JPY stabilize as carry demand reasserts itself. Elevated two-way volatility around the September decision is likely.
