Investment Analysis of the Japanese Market Amid the IMF's Upward Revision of Global Growth Projections

Based on the above analysis, I will provide you with a systematic and comprehensive investment analysis report.

The International Monetary Fund (IMF) released an update to its World Economic Outlook report on January 19, 2026, projecting that the global economy will grow by 3.3% in 2026, a 0.2 percentage point upward revision from its October 2025 forecast; growth in 2027 is projected to be 3.2%, unchanged from the previous forecast[1]. The World Bank followed suit, releasing a report on the same day that raised its 2026 global economic growth forecast to 2.6%, a 0.2 percentage point increase from its prior projection[2].

For the Japanese economy, the World Bank forecasts that Japan’s GDP growth will slow to 0.8% in 2026, a projection that reflects the structural challenges facing Japan’s economy in the process of reflation[2]. Nevertheless, the IMF’s optimistic outlook for the global economy provides a relatively favorable external environment for Japan’s export-oriented economy.

: Japan’s core CPI has remained above the 2% target consistently since April 2022, indicating the initial effectiveness of the Bank of Japan’s reflation strategy. However, the latest data shows that inflationary pressures are gradually easing, which aligns with the IMF’s forecast of slowing global inflation. The World Bank projects that global inflation will fall to 2.6% in 2026, 0.3 percentage points lower than its previous estimate[2].

: Japan’s largest trade union confederation (Rengo) is pushing for wage hikes of 5% or more in 2026. Although real wages are still in negative territory, the rate of decline narrowed in the second half of 2025. Sustained wage growth is expected to drive a wage-led consumption recovery[3].

: Japanese Prime Minister Sanae Takaichi has rolled out a ¥21.3 trillion economic stimulus package, which includes measures such as cash handouts, rice coupons, and electricity subsidies, and will strongly support growth in household spending[3].

The Tokyo Stock Price Index (TOPIX), as a broad-based index reflecting the overall performance of Japan’s main board market, is of great significance for assessing the overall trend of the Japanese stock market. Although complete real-time TOPIX data was not available for this analysis, an overview of the market structure shows:

• As of December 22, 2025, the proportion of Nikkei 225 constituent stocks with a price-to-book (P/B) ratio greater than 1 has risen sharply from 45% in 2022 to 75%, with a weighted average P/B ratio of 2.2x[3].
• Return on equity (ROE) has improved to 10.8%, higher than the average level of 8.9% before 2023[3].
• Japan’s three major banks have all raised their fiscal 2026 earnings guidance; Mitsubishi UFJ Financial Group and Sumitomo Mitsui Financial Group have raised their profit targets by approximately 5% and 15%, respectively[3].

The USD/JPY exchange rate closed at 157.93 yen per US dollar on January 19, 2026, falling 0.12% on the day[2]. From a technical analysis perspective:

Indicator	Value
Current Exchange Rate	157.93
5-Day Moving Average	158.03
Period Price Change	+0.27%
Annualized Volatility	4.18%
6-Day RSI	31.33

1. Potential Oversold Signal
   : The RSI indicator is 31.33, below the 30 oversold threshold, suggesting that the Japanese yen may have a short-term rebound opportunity[0].

2. Moving Average Support
   : The current exchange rate is slightly below the 5-day moving average, indicating that the Japanese yen has some short-term support.

3. Low Volatility
   : The annualized volatility is only 4.18%, indicating that the Japanese yen’s trend is relatively stable[0].

Based on recent data calculations, the correlation coefficient between the Japanese yen and the Nikkei 225 index is only 0.0697, indicating an extremely weak correlation between the two[0]. This means that the traditional carry trade logic of “yen depreciation → Nikkei rally” may no longer apply in the current market environment, and investors need to re-examine the mechanism by which exchange rate fluctuations affect the stock market.

:

1. Corporate Reform Dividends
   : The corporate governance reforms promoted by the Tokyo Stock Exchange have achieved remarkable results; the continuous improvement of P/B ratios and ROE has enhanced the investment appeal of Japanese enterprises[3].

2. Wage-Led Consumption Recovery
   : Improved expectations for real wage growth are expected to drive consumption recovery, benefiting the consumer staples sector. Brands such as Sapporo Holdings and Japan Tobacco have raised their full-year profit forecasts due to strong domestic sales[3].

3. Semiconductor Industry Investment
   : Japan’s efforts to revitalize its domestic semiconductor manufacturing industry (including Rapidus’ 2-nanometer chip project) will continue to support supply chain companies such as Tokyo Electron and Advantest[3].

4. Advantages of the Financial Sector
   : A sustained interest rate hike environment supports the financial sector, allowing banks to capture wider interest margins. The profit upgrades and share repurchase plans of Japan’s three major banks provide support for their stock prices[3].

:

1. Valuation Pressure
   : The Nikkei 225 index’s RSI indicates an overbought state, which may lead to short-term adjustment pressure.

2. Economic Growth Slowdown
   : The World Bank forecasts that Japan’s economic growth will only be 0.8% in 2026, limiting the room for corporate profit growth.

3. External Uncertainties
   : Global trade tensions may impact Japan’s export-oriented economy.

Sector	Rating	Rationale
Financial	Overweight	Widening interest margins in a rate hike cycle, bank profit upgrades
Semiconductor/Technology	Overweight	Government support policies, growing demand from AI and data centers
Consumer Staples	Overweight	Wage growth and fiscal stimulus drive consumption recovery
Industrial/Defense	Moderate Overweight	Global defense expenditure is in an upward cycle
Consumer Discretionary	Neutral	Automakers heavily reliant on the US market may face pressure
Utilities	Underweight	Rising interest rates are unfavorable for highly indebted enterprises

:

• The Bank of Japan’s ongoing interest rate hike cycle (raised to 0.75% in December 2025)[3]
• Inflation expectations support the yen’s purchasing power
• Fiscal stimulus measures boost economic confidence

:

• The market has fully priced in interest rate hikes
• Large-scale budget spending by the new prime minister has raised fiscal concerns
• Carry trade unwinding may have already been completed

: The Japanese yen is expected to fluctuate within the 155-162 range, with a moderate strengthening trend in the medium term[3].

1. Diversify Exchange Rate Risk
   : Given the weakened correlation between the Japanese yen and the Nikkei 225, it is recommended to manage exchange rate exposure through ETFs or hedging tools.

2. Focus on Corporate Quality
   : Prioritize allocation to enterprises with a P/B ratio greater than 1 and continuously improving ROE to avoid value traps.

3. Timing Entry Points
   : Wait for the Nikkei 225 index’s RSI to fall below 50 before increasing positions.

4. Monitor Policy Milestones
   : Bank of Japan monetary policy meetings, US inflation data, and the results of the Japanese general election (announcement expected on January 27, voting on February 8)[2].

The IMF’s upward revision of global economic growth forecasts provides a favorable external environment for the Japanese economy. Supported by corporate reforms, wage growth, and fiscal stimulus, the Japanese stock market is expected to continue its structural bull market. However, the short-term overbought condition of the Nikkei 225 index, slowing economic growth, and uncertainties in the yen’s trend require investors to maintain a cautiously optimistic attitude.

From an investment strategy perspective, it is recommended to focus on the financial, semiconductor, and consumer staples sectors, while managing risks through diversified allocation. The Japanese yen exchange rate may stage a short-term rebound against the backdrop of oversold technical indicators, but its medium-term trend will still depend on the normalization process of the Bank of Japan’s monetary policy.
