Morgan Stanley maintains a neutral stance on USD/JPY, waiting for a buy-on-dips opportunity after intervention or a pullback

Overview

This is a Morgan Stanley strategy research report on Japan and G10 foreign exchange. The report focuses on the drivers of USD/JPY as it approaches its 2024 high, the risk of MoF intervention, and the yen's relative performance. The core conclusion is that the exchange rate's rise has been dominated by broad USD strength, USD/JPY is currently close to fair value, the short-term stance remains neutral, and it is waiting for a better buy-on-dips entry point.

Core views

The report's core views include: first, the recent rise in USD/JPY differs from the earlier yen-selling phase and is more a reflection of broad USD strength; second, the risk of MoF intervention is rising but not yet imminent, because official wording has not yet explicitly pointed to "speculative" moves; third, the three-factor model shows USD/JPY is close to fair value, and the room for a significant break above fair value may be constrained by intervention expectations; fourth, for fair value to move meaningfully lower, aggressive Fed rate-cut pricing and a significant deterioration in global risk sentiment would need to occur simultaneously.

Analysis framework

The report uses a macro FX framework, decomposing USD/JPY into three factors: US terminal rate pricing, global risk sentiment, and Japan's terms of trade, while also using a USD regime framework to explain the shift from a Carry Regime to a USD Bullish Regime. At the same time, the report uses MoF officials' language, CFTC yen shorts, and nonresident yen funding demand to assess the probability of intervention.

Methodology notes

• FX fair valueThree-factor USD/JPY framework

  US terminal rate pricing, global risk sentiment, and Japan's terms of trade jointly explain USD/JPY.

  The report believes the current USD/JPY level is broadly close to the fair value implied by these three factors, so it is not advisable to chase the rally at current levels and instead wait for a clearer pullback or intervention trigger point.

• USD macro regimeCarry Regime, USD Bullish Regime, and Defense Regime

  The performance of the USD and JPY is characterized by combined changes in US real rates and inflation compensation.

  The earlier phase was closer to a Carry Regime, in which JPY performed weakly as a funding currency; after mid-May it shifted to a USD Bullish Regime, with US real rates rising and inflation compensation falling, leaving JPY relatively weak versus USD but potentially outperforming risk-sensitive currencies.

• Policy risk assessmentMoF intervention trigger watch

  Intervention risk depends not only on the exchange rate level, but also on whether officials judge the move to be speculative.

  Although USD/JPY is near high levels and MoF verbal warnings have intensified, the report believes officials have not yet clearly defined this round of volatility as speculative, so the probability of immediate intervention remains limited; if subsequent upside is driven by renewed JPY weakness, the probability of intervention would increase.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• USD/JPY

  Core trading instrument

  Strengths

  Broad USD strength, a hawkish FOMC, and market pricing for the Fed to keep rates high or even hike again support the exchange rate.

  Weaknesses

  It is currently close to the three-factor fair value, and expectations of MoF intervention may limit the room for a clear breakout higher.

  Comparison

  The report emphasizes that this round of gains has come more from USD strength, rather than the earlier phase that was mainly driven by JPY weakness.

  Risks

  If subsequent upside is again driven by rapid JPY weakness, the MoF is more likely to judge it as speculative moves and increase the probability of intervention.

• JPY

  Primary currency under analysis

  Strengths

  Falling oil prices improve Japan's terms of trade, and weak risk sentiment may also support JPY performance in non-USD crosses.

  Weaknesses

  In a Carry Regime, JPY usually performs the weakest as a funding currency; when facing a USD Bullish Regime, it may still underperform USD.

  Comparison

  The report says JPY has recently outperformed other G10 currencies except USD, indicating that the move is not simply broad-based yen weakness.

  Risks

  Continued accumulation of speculative yen shorts or strong funding demand may intensify volatility and increase the risk of policy intervention.

• USD

  Main driver of the USD/JPY rise

  Strengths

  The US economy and labor market remain resilient, while a hawkish FOMC stance and weaker risk sentiment support the dollar.

  Weaknesses

  If the market shifts to aggressive Fed rate-cut pricing and bonds significantly outperform equities, support for the USD may weaken.

  Comparison

  The report describes the post-mid-May environment as a USD Bullish Regime rather than simply a phase of JPY weakness.

  Risks

  If US demand slows sharply, inflation pressure declines, and a Defense Regime is triggered, the fair value of USD/JPY may move lower.

• Oil prices and Japan's terms of trade

  JPY fundamental variable

  Strengths

  Easing tensions in the Middle East, expectations of the reopening of the Strait of Hormuz, and falling oil prices improve Japan's terms of trade.

  Weaknesses

  This support is mainly reflected in JPY's relative performance against non-USD currencies, with limited ability to offset a strong USD.

  Comparison

  Compared with the 2022 commodity shock, the report believes the deterioration in Japan's terms of trade is smaller.

  Risks

  If Middle East tensions or energy supply risks flare up again, a renewed rise in oil prices could weaken fundamental support for JPY.

• Current strategy stanceNeutralMorgan Stanley maintains a neutral view on USD/JPY and JPY, waiting for a clearer buy-on-dips opportunity.
• Fair value assessmentClose to fair valueThe three-factor framework shows the current USD/JPY level is broadly reasonable, and the room to move significantly above fair value may be limited by the risk of MoF intervention.
• Intervention assessmentRisk rising but not yet imminentMoF verbal warnings have intensified, but recent wording has not yet clearly defined the FX moves as speculative.

Impact & implications

For trading, the report does not support chasing USD/JPY higher near the highs, but instead recommends waiting for a pullback, potential MoF intervention, or a clearer entry point. For macro allocation, JPY still has relative resilience in non-USD crosses, as falling oil prices improve Japan's terms of trade and weaker risk sentiment typically benefits JPY relative to risk-sensitive currencies.

Risks

• If USD/JPY continues to rise rapidly due to renewed JPY weakness, the probability of MoF intervention could increase significantly.
• A further hawkish shift by the FOMC or renewed market repricing toward rate hikes could continue to support the USD and push USD/JPY higher.
• A clear weakening in AI-related stocks and capital expenditure could weigh on risk assets and alter global risk sentiment.
• If US growth slows sharply and triggers aggressive Fed rate-cut pricing, the fair value of USD/JPY could move meaningfully lower.
• Developments in the Middle East, the Strait of Hormuz, and oil prices could affect Japan's terms of trade and JPY performance.
• Morgan Stanley discloses that its business may have conflicts of interest with companies or instruments covered by its research, and investors should not rely solely on this report for decision-making.

What to watch

• Whether MoF officials explicitly describe recent FX moves as "speculative."
• Whether USD/JPY breaks above and remains sustainably above the 2024 high near 161.95.
• Whether CFTC speculative yen shorts and overseas nonresident yen funding demand continue to rise.
• Repricing of US terminal rates and expectations for Fed cuts or hikes.
• Global risk sentiment, especially equities versus bonds performance and trends in AI-related stocks.
• Oil prices, developments in the Strait of Hormuz, and changes in Japan's terms of trade.
