USD/JPY Price Forecast - USD to JPY Stabilizes at 156.70 as Japan’s Fiscal Stimulus Collides with BoJ Caution

Fiscal Pressure and Policy Contradictions Weigh on the Yen

USD/JPY is trading near 156.70 after touching a weekly high of 157.70 before retreating on renewed intervention warnings from Tokyo. Japan’s ¥21.3 trillion economic stimulus, including ¥17.7 trillion in direct spending and ¥2.7 trillion in tax cuts, is expanding fiscal stress and fueling speculation of further yen weakness. The yield on 10-year Japanese government bonds remains elevated near 1.08%, reflecting growing investor concern over rising debt issuance.

BoJ Delay and Market Expectations for Rate Normalization

Governor Kazuo Ueda’s recent remarks reinforced market doubts about near-term tightening. Despite inflation staying above the BoJ’s 2% target, the central bank appears unwilling to raise rates amid political resistance from Prime Minister Sanae Takaichi’s pro-stimulus administration. Surveys indicate over 55% of economists now expect a 0.75% policy rate by December, but the consensus sees the decision postponed until Q1 2026.

U.S. Dollar Momentum and Yield Divergence

The U.S. Dollar Index (DXY) remains firm above 100.30, buoyed by resilient Treasury yields and stronger-than-expected U.S. labor data. The delayed Nonfarm Payrolls report showed consistent job growth, while FOMC minutes revealed caution about premature rate cuts. The 10-year Treasury yield hovers at 4.38%, widening the interest rate gap versus Japan’s near-zero policy rate — a key driver sustaining USD/JPY above 156.

Technical Structure and Price Action Levels for USD/JPY

The pair maintains a constructive structure above the 156.00 pivot. Immediate resistance stands at 157.70, coinciding with the 2025 high-day close, followed by 158.88 — the yearly high and next bullish objective. On the downside, strong support sits between 156.20 and 155.40, aligning with the lower trendline from November. Momentum indicators show the RSI near 58, signaling modest bullish energy but limited extension beyond 158.00 without new catalysts. A close below 155.60 would trigger corrective downside toward 154.45, where intervention support is anticipated.

Intervention Threats and Policy Signaling from Tokyo

Finance Minister Satsuki Katayama issued the strongest warning yet, stating that Japan “will take appropriate action against disorderly moves,” signaling preparedness to utilize excess foreign reserves for intervention. The Ministry of Finance holds over $1.2 trillion in reserves, giving ample capacity to stabilize the yen if USD/JPY breaches 158. However, recent comments suggest Tokyo’s tolerance band remains flexible between 155.00–160.00, making intervention likely only after a decisive break above 158.50.

Fiscal-Monetary Divergence: The Core Structural Driver

The policy divide between Japan’s fiscal expansion and the BoJ’s slow exit from ultra-loose conditions continues to erode yen confidence. Fiscal deficits are projected to exceed 6.1% of GDP in FY2025, while debt-to-GDP stands above 260%. This imbalance has pushed real yields deeper into negative territory, encouraging Japanese investors to chase overseas assets and weakening the currency further.

Market Positioning and Institutional Sentiment

CFTC data shows net yen shorts rising for the fourth consecutive week to 90,000 contracts — the highest since May 2024. Hedge funds remain positioned for continued yen depreciation, though intervention risk has reduced leverage exposure. Options markets price a 1.1% implied volatility spike for December expiries, indicating anticipation of BoJ or MoF action within weeks.

Global Macro Impact and Risk Appetite

The broader risk-on environment — with the S&P 500 up 3% this month and the Nasdaq surpassing 17,000 — limits safe-haven demand for the yen. However, renewed geopolitical tensions or a U.S. data miss could rapidly unwind USD/JPY longs. Traders remain cautious ahead of upcoming U.S. Retail Sales data and the BoJ’s December meeting minutes.

Analytical Outlook and Directional View

USD/JPY retains a bullish bias while trading above 156.00, supported by yield divergence and structural yen weakness. The short-term ceiling remains 158.00, where intervention fears intensify. A confirmed break above this threshold would target 158.88–159.20. Conversely, a decline below 155.40 could shift sentiment toward a deeper retracement to 154.00. With fiscal stimulus fueling liquidity and the BoJ still lagging global peers, upward bias remains dominant — though the risk of policy intervention caps further appreciation.

Verdict: Hold with Upward Bias

The technical and fundamental balance suggests USD/JPY (156.70) is a Hold, leaning bullish toward 158.00 in the near term. The risk of verbal or direct intervention limits upside beyond that zone, but sustained yield divergence keeps downside contained unless BoJ signals an imminent rate shift.
