UBS has adjusted its USD/JPY forecasts, predicting rates of 143 by the end of 2025 and 140 by the end of 2026. The changes are attributed to Japanese political uncertainty and a cautious stance from the Bank of Japan, in addition to strong equity market performance affecting the yen.
Despite the anticipation of another interest rate hike by the Bank of Japan before January 2026, the yen has not yet seen advantages from these expectations. Japan’s robust equity market and reduced volatility are further factors impacting the currency’s performance.
Yen Performance Factors
No coordinated action, like a new Plaza Accord, is evident to promote a stronger yen. UBS expects the USD/JPY pair to remain mainly within the 140–150 range rather than dropping below this range.
In the U.S., the dollar faces challenges due to a weakening labour market, which is influencing short-term Treasury yields. This economic environment keeps the dollar under pressure.
We see the dollar-yen pair settling into a 140-150 range for the foreseeable future. Headwinds for the yen, such as political uncertainty in Japan and a cautious Bank of Japan, are being met by growing weakness in the U.S. dollar. As a result, we do not expect a major breakout in either direction in the coming weeks.
Political instability in Japan continues to be a key factor, as recent polls this month show the current administration’s approval rating has fallen below 20%, limiting the Bank of Japan’s ability to act aggressively. Furthermore, the Nikkei 225 index remains strong, having gained over 20% so far in 2025, which discourages safe-haven flows into the yen. This environment suggests that any significant yen strength is unlikely for now.
US Labor Market Weakness
On the other side of the pair, the U.S. labor market is showing clear signs of cooling. For instance, the August 2025 non-farm payrolls report we saw earlier this month came in at just 95,000, missing expectations and marking the third straight month of weak job growth. This softness is putting downward pressure on short-term Treasury yields, capping any potential dollar upside.
Given this outlook for low volatility and a defined range, selling options appears to be a sensible strategy. We believe traders should consider strategies like an iron condor with strikes set outside the 140-150 channel to collect premium from the expected sideways movement. This approach profits from the passage of time and the pair’s failure to make a decisive move.
Looking back at history, there is little to suggest a coordinated intervention to strengthen the yen, similar to what we saw with the Plaza Accord in 1985, is being considered. Therefore, the 140 level should act as a strong floor for the pair. Any rallies toward the upper end of the range near 150 will likely face resistance due to the weakening U.S. economic picture.
