USD/JPY Exchange Rate Analysis: UBS Forecasts Gradual Decline to 138 by September 2025

After a significant drop in early July, the USD/JPY exchange rate has stabilized within a range recently. UBS analysts predict a gradual decline in the exchange rate, reaching 138 by September 2025.

The bank’s forecasts for USD/JPY include 147 for December 2024, 143 for March 2025, and 140 for June 2025, with a new target of 138 introduced for September 2025.

Several factors contribute to this anticipated downtrend, including speculative positioning in leveraged FX markets and US interest rate market trends. The USD/JPY has also converged with the US-Japan 10-year real yield differential, limiting further downside potential.

UBS highlights potential risks to their forecast, such as upcoming US economic data and the LDP leadership election in Japan. Despite near-term stability, the bank expects a medium-term downtrend for the USD/JPY.

With the Fed expected to continue cutting policy rates and gradual rate hikes from the BoJ, the narrowing of US-Japan yield differentials will likely drag the USD/JPY lower over the medium term.
