Yen Weakness Extends Into New Week
USD/JPY is trading above 160 once again, with the yen heading into the new week under renewed pressure despite markets pricing in nearly two full Bank of Japan rate hikes by year-end.
The move raises a key question for traders: if Japanese authorities may intervene and the Bank of Japan is expected to tighten policy, why is the yen still struggling?
U.S. Yields Remain The Main Driver
The answer lies largely in U.S. rate expectations and Treasury yields.
Over the past week, USD/JPY has shown its strongest correlation with Federal Reserve pricing one year ahead, followed by U.S. two-year Treasury yields and U.S. 10-year Treasury yields.
Front-End Yield Differentials Matter
The strongest relationship has been with Fed pricing one year forward, at 0.80, followed by U.S. two-year yields at 0.73.
This highlights the importance of front-end yield differentials. As long as markets believe the Fed may keep policy tight or even raise rates again, the dollar remains well supported against the yen.
Yen’s Haven Role Remains Weak
USD/JPY has also maintained a positive correlation with VIX futures and the MOVE index.
That suggests the yen’s traditional role as a risk-aversion proxy remains muted. In the current environment, higher U.S. yields and strong dollar momentum are dominating the currency pair more than classic safe-haven flows.
U.S. Exceptionalism Still Supports The Dollar
Many investors have spent the past year waiting for clearer signs of a U.S. slowdown, but recent data are pointing in the opposite direction.
Citi’s U.S. Economic Surprise Index has climbed to its highest level in years, showing that economic releases have consistently beaten expectations.
Payrolls Reinforce Growth Momentum
The latest nonfarm payrolls report strengthened that message.
The U.S. economy added 172,000 jobs in May, more than double consensus forecasts. Revisions also added another 93,000 jobs to March and April payroll growth.
Labor Market Still Looks Resilient
The unemployment rate held at 4.3%, while the three-month average payroll gain reached 188,000.
Those numbers do not suggest an economy close to capitulation. Instead, they reinforce the view that U.S. growth momentum remains stronger than many had expected.
Markets Reprice Fed Risk
Investors are now waking up to the possibility that the Federal Reserve may be behind the curve in fighting inflation.
Futures are pricing in 41 basis points of tightening over the coming year, a major shift from earlier expectations that the next meaningful Fed move would be a rate cut.
Fed Easing Bias Looks Vulnerable
The Fed still formally retains an easing bias, based on the view that risks to its dual mandate are tilted more toward downside risks for employment than upside risks for inflation.
But with the labor market reaccelerating, that view is becoming harder to defend. Persistent inflation may now be the bigger risk.
Policy Error Concerns Return
The idea that policymakers can simply look through the latest inflation pulse is becoming less convincing.
Some traders see a risk that the Fed could repeat the mistake made after the pandemic, when officials were slow to respond to building price pressures.
What Could Stop The Dollar?
Given the macro backdrop, the prospects for sustained yen appreciation remain limited.
Japanese intervention since late April has not been enough to offset the combination of a reaccelerating U.S. economy and growing expectations that the Fed may need to tighten further.
U.S. Weakness Would Be Needed
The most obvious catalyst for yen strength would be a meaningful deterioration in U.S. economic data.
Because USD/JPY is closely tied to the front end of the U.S. yield curve, sustained yen appreciation would likely require a material repricing lower in Treasury yields and Fed expectations. For now, that outcome looks remote.
Risk-Off Shock Could Also Matter
A second possible catalyst would be a disorderly unwind in riskier assets that pressures carry trades.
However, with yen borrowing costs still low and stable, and with the currency continuing to weaken, pressure on leveraged carry positions remains limited. It would likely take a major fall in risk assets to change that dynamic.
Inflation Data Takes Center Stage
U.S. inflation data will be the key known risk event next week.
Another strong upside surprise would add pressure on the Fed to acknowledge that risks to its mandate have shifted toward inflation rather than employment.
PPI Could Be A Major Volatility Event
Although CPI is usually the larger market mover, upstream price pressures may now matter more when assessing whether the inflation surge is sustainable.
That means PPI could become the more important volatility event, while inflation expectations data will add further context around both releases.
Japan PPI Also In Focus
In Japan, the May producer price index will also be important after April’s large upside surprise.
A stronger reading could reinforce expectations for Bank of Japan tightening, although recent price action suggests Japanese data alone may not be enough to reverse USD/JPY’s upward trend.
SpaceX IPO Could Shape Risk Appetite
The likely SpaceX IPO is another event that may influence broader sentiment.
Given the scale of the offering, a strong debut could support risk appetite, carry trades and capital flows into higher-yielding assets. That would likely be another headwind for the yen.
Technical Picture Remains Bullish
The technical setup remains clearly supportive of USD/JPY bulls.
The pair is grinding higher within a gradual uptrend and is moving closer to testing the 2026 high of 160.73.
Key Levels To Watch
The 160.73 level is the immediate resistance to watch. A break above it could open the way toward the multi-decade high of 161.95 set in 2024.
On the downside, uptrend support sits around 159.50. Below that, the 50-day moving average and former breakout level near 157.92 become the next important areas.
Momentum Favours The Bulls
Momentum indicators also support the bullish case.
The RSI is trending higher without yet reaching overbought territory, while MACD has moved further into positive territory after crossing above the signal line nearly a month ago.
Long Setups Still Favoured
The overall message remains constructive for USD/JPY.
As long as U.S. data stay strong, Fed tightening risk remains alive and U.S. yields hold firm, the path of least resistance appears higher. Japanese intervention risk may slow the move, but it has not yet been enough to reverse the trend.
