[FCI Introduction 4-Layer Analysis New Version + Latest Investor Category Trading Trends] Today's Japanese Stock Market: Perspectives for Seeing the Next Move That Work for Future Investment Decisions
Thank you for accessing this article.
In this analysis, we have added an evaluation of the monetary policy environment as a "Japanese version of FCI," making the analysis clearer.
This allows us to understand not just whether stock prices have risen or fallen, but also the current policy situation (whether we are currently in a real tightening or easing environment), which can be used as a guideline for future stock price increases and decreases.
Prime Minister Takaichi delivered her policy speech in the Diet. Based on the philosophy that economics comes before fiscal policy, she declared that under responsible proactive fiscal policy, strategic fiscal spending would be implemented while ensuring fiscal sustainability and securing market confidence by reducing the net debt-to-GDP ratio.
Until now, Ministry of Finance-affiliated politicians and mass media have argued for fiscal austerity using primary balance as a shield, with a "household budget logic" based on fixed annual salaries. However, the Takaichi administration is completely different in that it adopts a "corporate management logic" focusing on "net debt balance" and introduces balance sheet thinking that considers economic growth through strategic investment.
Now, in this article, we focused on the Nikkei Average and analyzed the Japanese stock market using a 4-layer analysis format. This is a comprehensive analysis that differs from typical economic articles, examining four layers: Market, Policy, Trade, and Geopolitics.
Even following news and SNS, you often wonder "So what does this all mean? Is now a buying opportunity? What will happen to US and Japanese stocks? What about the economy?" — There's so much similar information online, and just looking at it doesn't help, right?
This article, which eliminates such confusion, organizes various data so you can see the next move.



Foreign investor capital inflows are prominent. Aside from retail investors (margin trading), buying funds are increasing. However, looking at flows since April, the situation is as shown above.
Japan Stock 4-Layer Analysis Report (4th Week of October 2025)
Theme: Risk-On Recovery Supported by FCI Easing and Geopolitical Risk Subsidence
Overview
The Nikkei Average reached 49,337 yen (+1.43%), updating year-to-date highs. TOPIX also rose +0.52%, with sectors like "Non-ferrous Metals," "Telecommunications," and "Electric Equipment" leading. However, the Nikkei VI rose to 28.84 (+5.18%), showing some short-term overheating.
Globally, while NASDAQ +18.4% and DAX +21.6% showed strength in Western markets, Japanese stocks remained steady backed by yen weakness, FCI easing direction, and policy stability.
🔹 Market Layer
Stock price momentum: Nikkei +22.3%, DAX +21.6%, NASDAQ +18.4%. Among the top in major countries.
Volatility: Nikkei VI at 28 is high; the gap with VIX (17) has widened = risk premium remains elevated.
Liquidity: TSE trading value is solid, with rotation in telecom, semiconductors, and non-ferrous sectors.
The sector heatmap shows tech/materials stocks like SoftBank Group (+5.7%), Disco (+5.0%), and Fujikura (+3.9%) leading.
Z-score (Market Overall) = +0.84 (risk-on dominance, but volatility remains elevated)
🔹 Policy Layer (Policy/Financial Environment: Japanese Version FCI)
Interest rates: 10-year JGB yield 0.99% (+0.038) = slight increase, continued pricing of policy easing.
FX: USDJPY 152.98 (+0.24%) = yen weakness maintained, supporting export stocks.
Credit: HY spread narrowing trend, corporate financing environment stable.
Equity: Nikkei/TOPIX rise shows risk asset element in easing direction.
Liquidity: Trading value solid, Tankan lending attitude DI also improving.
Japanese version FCI (Headline) = -0.47 (Z-score standardized) → Financial environment is "in easing direction" (Sign convention: + = tightening, - = easing) ⇒ Background: BOJ early rate hike expectations receding, continued liquidity supply. Effects of supporting the market through Policy→FCI route are evident.
🔹 Trade Layer (Trade/External Demand)
Global trade volume index (GSCPI): Improving trend. Supply chain pressure at lowest level since 2022.
BDI/SCFI: Rising trend, particularly steel/resource-related shipping recovering.
Export-related stocks (machinery, non-ferrous, shipbuilding) outperforming TOPIX.
Z-score (Trade) = +0.61 → Global logistics/manufacturing recovery is a tailwind.
🔹 Geopolitics Layer (Geopolitics/Energy)
GPR (Geopolitical Risk Index): Middle East/Eastern Europe risks are localized but overall calming.
Energy prices (Brent/JKM): Stable range, inflationary pressure limited.
Election/policy risk: With US presidential election approaching, FX/tariff policy under watch.
Z-score (Geopolitics) = -0.22 → Geopolitical stability is a supporting factor for risk assets.
Transmission Path (Policy → FCI → Market)
SVAR/LP analysis (weekly-based estimation) shows that the "interest rate decline → FCI easing → stock return increase" mediation path remains effective. FEVD shows about 36% of market fluctuations are attributed to FCI shocks. Particularly strong resonance with NASDAQ/DAX, with Japanese version following global liquidity cycles observed.
Outlook: Scenarios Through Year-End
Base case (65% probability): Nikkei stabilizes above 50,000 with yen weakness + continued policy easing.
Risk scenario (25%): Yen appreciation shock from US interest rate re-rise/FX intervention.
Positive scenario (10%): TOPIX updates all-time highs led by AI/capital investment.
While short-term adjustments are expected due to volatility rise (VI 28 level), medium-term trend maintains risk-on.
🧩 Summary
The Japanese market is currently in a multilayered risk-on phase accompanied by trade/stock market recovery, centered on "financial environment easing (-FCI)" and "geopolitical stability."
The Nikkei Average is functioning as a "mediation point" for policy easing and continued global economic conditions, and the upward trend is expected to be maintained while the "Policy → FCI → Market" chain remains alive.
