The dollar slid to start September as mixed signals on the Federal Reserve’s next move kept traders on edge ahead of a pivotal inflation report, while a surging yen reverberated across global currency markets, according to market data. The Bloomberg Dollar Spot Index closed the week 0.7% lower, even after paring the loss on Friday following a stronger-than-expected jobs report that revived bets on a Fed rate hike later this month.
Federal Reserve Rate Hike Expectations Shift After Jobs Data
Traders priced in about a 60% chance of a quarter-point rate hike following the latest employment data, up from around even odds before the report, according to Noah Buffam, strategist at CIBC Capital Markets. “The next trend move in the dollar likely depends on inflation next week and its read through to the September Fed,” Buffam said. Friday’s data showed that job growth surged in August, while the unemployment rate held steady at 4.1%.
Earlier in the week, the greenback touched its weakest level since May after Fed Gov. Christopher Waller pointed to progress on inflation, which damped expectations for an imminent increase in borrowing costs. Waller’s speech “was a little more dovish than most were expecting,” according to Chris Turner, ING Groep NV’s head of global markets.
Did you know? Options investors are overall turning more negative regarding the outlook for the greenback, as evidenced by a widely monitored indicator of market sentiment—one-month risk reversals—shifting back to a bearish stance on the trade-weighted dollar during the week.
Japanese Yen Rallies Amid Bank of Japan Policy Expectations
Adding to the dollar’s weekly decline was a sharp rally in the yen. The Japanese currency posted its best week since July, gaining about 2.4% against the dollar. Market analysts indicate that this surge was driven by anticipations that the Bank of Japan could implement a quarter-point benchmark rate increase this month while keeping the possibility open for additional rapid hikes down the road.
Wall Street strategists are actively positioning for further weakness on the back of these developments. Bank of America recommends selling the dollar against the yen, forecasting that the Japanese currency will strengthen to ¥149 per dollar by year-end. Meanwhile, TD Securities maintains a “moderately bearish dollar view” for the rest of the year.
Inflation Data Crucial for Upcoming Central Bank Decisions
An upcoming consumer-price release slated for next week carries the weight to lock in forecasts regarding the central bank’s subsequent action and, consequently, the trajectory of the dollar. Buffam pointed out that there remains a danger of the figures coming in “too hot,” a scenario that could create space for the greenback to mount a near-term bounce.

Conversely, an in-line inflation print “would likely help the Fed avoid a September hike, keeping the broader backdrop biased against the dollar,” according to Jayati Bharadwaj, head of FX strategy at TD Securities.
Pro Tip for Currency Traders
Monitor upcoming consumer price index (CPI) releases closely. As noted by CIBC Capital Markets and TD Securities, market positioning is highly sensitive to inflation prints, which directly dictate whether central banks will pause or accelerate interest rate adjustments.
