The dollar plummeted at the start of September! Federal Reserve Governor Waller adopted a dovish stance, while rising expectations of interest rate hikes by the Bank of Japan triggered a surge in the yen.

Noticing that as traders reduced their bets on a Fed rate hike this month, combined with the soaring yen impacting global forex markets, the dollar has weakened as September approaches. After hitting its lowest level since May on Thursday, the Bloomberg Dollar Spot Index is expected to close down 0.7% this week. Following comments from Fed Governor Christopher Waller noting progress on inflation, investors currently place about a 50% chance on a rate hike at the Fed's decision on September 16; meanwhile, ongoing concerns about the U.S. fiscal outlook have further increased the pressure on the Fed. In Japan, the yen is poised to record its best performance since July, rising 2.7% against the dollar. This trend has been driven by market expectations that the Bank of Japan may raise its benchmark interest rate by 25 basis points this month, while also leaving the door open for faster hikes thereafter. Noah Baafum, a strategist at Canadian Imperial Bank of Commerce, stated, "The dollar has pulled back this week as Fed officials have leaned dovish and the surge of the yen has impacted a broader array of dollar assets." Traders question the likelihood of a Fed rate hike, causing the dollar to drop to its lowest level since May. Traders are turning their focus to Friday's non-farm payroll data (with the unemployment rate expected to hold steady at 4.1% in August), followed by next week's critically important Consumer Price Index (CPI) report. The release of this data may shape market expectations regarding the Fed's next moves, thereby determining the direction of the dollar. Jayati Baladwaj, head of forex strategy at TD Securities, noted, "If the inflation data meets expectations, it will help the Fed avoid a rate hike in September, keeping the overall macro environment unfavorable for the dollar." Before this week's decline, speculators had already started trimming their bullish positions on the dollar. According to the Commodity Futures Trading Commission (CFTC), as of the week ending August 25, hedge funds, asset managers, and other traders reduced their dollar long positions to about $27.6 billion. This is down from nearly $50 billion at the end of July, when bullish positions reached their largest size since 2014. Wall Street strategists are also preparing for further weakness. Bank of America recommends selling dollars to buy yen, forecasting that the yen will appreciate to 149 per dollar by the end of the year. Meanwhile, TD Securities maintains a "moderately bearish" outlook on the dollar for the remainder of the year.
