UBS raises USD/JPY forecast to 143 for end-2025 amid Japan political uncertainty

UBS has revised its USD/JPY forecast upward to 143 for end-2025 and 140 for end-2026, driven by heightened political uncertainty in Japan, including upcoming LDP leadership elections and concerns over fiscal discipline. This instability is fostering market caution and contributing to perceptions of a dovish Bank of Japan stance despite inflationary pressures. Markets have already priced in a BoJ rate hike by January 2026, creating potential downside risk for JPY bulls if the central bank delays rate increases while the Federal Reserve implements cuts.

Analysis

UBS has raised its USD/JPY forecast to 143 for the end of 2025 and 140 for the end of 2026, citing heightened political uncertainty in Japan that has surpassed previous expectations. The upcoming Liberal Democratic Party (LDP) leadership election, coupled with its current minority government status, is fostering market caution regarding potential fiscal indiscipline and a possible Diet election. This political instability is contributing to a market perception of a persistently dovish Bank of Japan (BoJ), despite domestic inflationary pressures, and has impacted the long end of the Japanese Government Bond curve. A key risk for yen bulls stems from the market having already priced in a BoJ rate hike by the January 2026 meeting; a delay in this hike, especially if the U.S. Federal Reserve begins cutting rates, could lead to significant JPY downside.

Key Decisions for Investors

• Investors should reconsider or hedge long-yen positions given the revised UBS forecast and the underlying political drivers suggesting a weaker currency outlook.
• Monitor the outcome of the upcoming LDP leadership elections, as the new leadership's stance on fiscal policy and a potential Diet election will be a primary catalyst for the USD/JPY exchange rate.
• Be cautious of the asymmetric risk in the yen, as a failure by the Bank of Japan to deliver its priced-in rate hike by early 2026 could trigger a sharp depreciation against the dollar, particularly if the Federal Reserve is in an easing cycle.
