Morgan Stanley predicts a near 10% appreciation of the Japanese yen against the US dollar due to potential Federal Reserve rate cuts and market mispricing, forecasting a decline to 140 by Q1 2026 before stabilizing at 147 by year-end 2026, depending on economic conditions.

Abstract generation in progress

According to market analysis from Morgan Stanley, a significant shift in monetary policy could trigger substantial currency realignment in the coming quarters. The investment bank’s strategists project that the Japanese yen could strengthen by nearly 10% against the US dollar if the Federal Reserve embarks on consecutive interest rate cuts as economic indicators signal potential slowdown.

The Case for Yen Appreciation

Analysts including Matthew Hornbach highlight a critical technical divergence: the USD/JPY pair currently trades above its fundamental fair value level. This mispricing creates vulnerability for the dollar should broader conditions shift. As US Treasury yields compress in response to rate cuts, the equilibrium level for USD/JPY would logically decline, creating downward pressure on the exchange rate.

The interest rates in Japan present an additional variable in this equation. While Japanese fiscal policy remains relatively restrained, the structural interest rate differential between the two nations will narrow significantly if the Federal Reserve moves toward lower rates. This compression of yield spreads removes one of the primary supports for dollar strength.

Timeline and Market Expectations

Morgan Stanley’s forecast includes specific targets mapped to distinct periods:

First Quarter 2026: USD/JPY anticipated to decline toward the 140 level, reflecting the initial impact of Fed rate reductions and fair value normalization
Year-End 2026: The exchange rate projected to rebound toward 147 as the US economy stabilizes and carry trade demand resurfaces

The Counterbalancing Factors

The strategists note an important inflection point. Once US economic momentum returns in the second half of 2026, appetite for yen-funded carry trades would likely revive. This renewed speculative positioning could reverse the appreciation trend, pushing USD/JPY back toward higher levels despite the interest rate environment.

The key uncertainty remains whether Fed interest rate cuts materialize as decisively as current market expectations suggest, and whether Japanese interest rates in Japan will remain accommodative to support this scenario.
