USD/JPY at highest level since July: Carry trade weighs on the Yen

Market impact: Moderately bullish USD/JPY in the near term, but increasingly vulnerable to sharp reversals.

The key market signal is that widening yield differentials and risk appetite for carry positions are currently outweighing the yen-positive effect of higher Japanese government-bond yields and expectations of a possible Bank of Japan hike. Japan’s 10-year yield reaching 3% raises the potential return on yen assets, but it also intensifies fiscal-sustainability concerns because higher borrowing costs increase the burden of servicing Japan’s large public debt. That combination can weaken, rather than strengthen, the yen if markets interpret rising yields as a fiscal-risk premium.

For USD/JPY, the immediate bias remains upward: dollar demand is being reinforced by safe-haven flows and expectations that higher oil prices could keep US inflation elevated, limiting expectations for easier Federal Reserve policy. The carry mechanism remains supportive because US rates are still materially above Japanese borrowing costs, encouraging investors to fund positions in yen and buy higher-yielding dollar assets.

However, the move is not one-directional. A Bank of Japan hike, stronger official guidance against yen weakness, or a reduction in US rate-hike expectations could trigger carry-trade unwinding. Because carry positions are often leveraged, even a modest fall in USD/JPY can generate accelerated yen buying. The article’s technical framework identifies a possible correction toward 158.97 before renewed tests of 160.27 and 160.67; these should be treated as market reference points rather than a standalone directional signal.

What could extend USD/JPY gains:

• Strong US employment data or higher wage/inflation readings.
• Further increases in oil prices that delay expectations of Fed easing.
• Continued geopolitical demand for the dollar.
• BoJ caution or fiscal concerns undermining confidence in the yen.

What could invalidate the bullish view:

• A clearly hawkish BoJ message or an earlier-than-expected rate increase.
• Evidence that Japan’s higher yields are attracting repatriation flows rather than signaling fiscal stress.
• A weak US payrolls report that sharply lowers US yield expectations.
• An abrupt deterioration in global risk sentiment, which could unwind carry trades despite safe-haven demand for the dollar.

The most important near-term catalyst is the US Nonfarm Payrolls report on Friday, September 4, 2026, because it could reset expectations for US rates and determine whether USD/JPY consolidates near its recent high or resumes its advance. Traders should also monitor US Treasury yields, Japanese fiscal announcements, BoJ communication, oil prices, and signs of intervention-related rhetoric from Japanese officials.
