Japanese Yen Outlook: USD/JPY tethered to Fed cut bets after Jackson Hole shift

• Fed cut pricing driving USD/JPY more than yields or spreads
• Powell’s Jackson Hole remarks tilt risks lower for the dollar
• Key support under 147.00 continues to attract buying
• Breakout needs fresh catalyst from data or Fedspeak

USD/JPY Weekly Outlook Summary

Market pricing for rate cuts from the Federal Reserve continues to drive USD/JPY movements, putting Fedspeak, economic data and the future composition of the FOMC on the radar for traders this week. Directionally, risks are skewing lower for USD/JPY following Jerome Powell’s dovish speech at Jackson Hole last Friday, both from a fundamental and technical perspective. The onus is now on the data to prevent a rate cut in September, rather than the other way around.

Fed Rate Cut Pricing Dictates Direction

The first graphic reveals that over both the past week (left-hand pane) and month (right-hand pane), market expectations for Fed rate cuts have been highly correlated with USD/JPY movements, showing a far stronger relationship than other known drivers such as US short and longer-dated Treasury yields, yield spreads between the US and Japan, and the outlook for US equity market volatility.

The yellow line tracks market pricing for Fed rate cuts out to the middle of 2026, as proxied by the shape of the Fed funds futures curve between June this year and next. At -0.97 and -0.92 respectively, it shows that as rate cut pricing has grown, USD/JPY has almost always fallen, and vice versa when the opposite has occurred. Even though correlations with short and longer-dated Treasury yields and yield spreads have strengthened recently, they remain far less influential than the linkage between USD/JPY and the Fed funds outlook.

Powell Pivot Sparks Dovish Repricing  

Looking at the next graphic tracking shifts across the US interest rate curve over the past month, the largest moves occurred immediately after the July payrolls report on August 1 and Jerome Powell’s speech last Friday. They just happen to be the biggest one-day moves in USD/JPY over the same period.

The strength of the relationship between USD/JPY and Fed rate cut pricing suggests anything that can materially alter the latter is likely to be influential in the former this week.

Data Risk Limited

Looking at the US and Japanese calendars, while both are busy, there few releases with the potential to spark major market volatility, including the Fed’s preferred underlying inflation measure—the core PCE deflator released on Friday.

So good have data scientists become in mapping information from CPI and PPI reports released earlier in the month that rarely does the PCE deliver a meaningful surprise, seeing it slip down the rankings of known risk events. If anything, given questions about the underlying health of the US labour market, it’s the incomes and consumption data released alongside the PCE measure that screen as more important for the Fed rate outlook. After all, we’re talking about the largest part of the US economy and the fuel that powers it—incomes growth.

Those figures, along with jobless claims and the second read of Q2 GDP released on Thursday, loom as the most likely US data catalysts to spark volatility. While there are Treasury auctions of two, five and seven-year debt, they may find solid support from the dovish shift in Fed expectations, potentially limiting their ability to weaken the dollar on signs of waning demand.

While Japan’s calendar remains a distant secondary consideration for traders, Friday’s Tokyo CPI report could spark volatility if it meaningfully shifts pricing for a Bank of Japan rate hike by year-end. Other Japanese releases are unlikely to move the dial for USD/JPY direction. A speech from BoJ board member Nakagawa mid-week may also provide some insight into the likelihood of a rate hike before year-end.

FOMC Composition in Focus

On the Fed speakers’ calendar, attention will be on FOMC members Collins, Williams and Waller given they all vote on policy this year.

Although not listed in any calendar, perhaps the most important catalyst for US rates this week will come from Donald Trump’s continued attacks on FOMC governor Lisa Cook over allegations of mortgage fraud. With three governors already aligned with Trump’s push for rapid rate cuts, Cook’s potential departure would hand him a majority on the Board, not only greatly improving the likelihood of large-scale cuts this year but also giving him influence over the composition of the broader FOMC through appointments of regional Fed presidents. If Cook is replaced, it’s highly likely the USD will weaken in response.

USD/JPY Remains Rangebound

USD/JPY remains rangebound despite printing a bearish key reversal candle on Friday, attracting bids once again beneath 147.00 on Monday. We’ve now seen ten dips under this level during August, all of which have been reversed. That suggests that until we see a close beneath it, along with the influential 50-day moving average sitting just below, this zone remains a solid area for traders to consider establishing long positions.

On the topside, 148.80, 150 and the 200-day moving average are the levels to watch, offering either potential targets for longs or possible entry points for shorts given the rangy August price action. Beyond the two big-figure range the pair has been stuck over much of the month, support sits at 146.00 and 144.42, while resistance is found at 151.00 and 152.40. These levels appear out of reach this week unless a major catalyst shifts Fed pricing.

From a momentum perspective, both RSI (14) and MACD are neutral, putting more emphasis on price action and fundamental catalysts to guide decision-making.
