Japan equities move into the 3% yield era, with financials favored but the AI rally not necessarily over

Overview

This report discusses the impact of the rapid rise in Japan's long-term yields on Japanese equities, fiscal sustainability, the regional financial system, the corporate sector, and the AI semiconductor and financial sectors. The report notes that high oil prices, rising corporate price indices, supplementary budgets, and tax-cut discussions together have pushed Japan's 10-year government bond yields sharply higher and have at times pressured AI semiconductor stocks. However, the authors argue that a 3% yield is not an abnormal level in light of Japan's 2030 potential growth and inflation target context, and the key issue is the speed of the rise and the eventual terminal level.

Core views

The core view is that the Japanese equity market does not have to collapse even if the 10-year JGB yield enters the roughly 3% range. Reasons include: the risk of a sharp yen appreciation has declined, and yen depreciation can partly offset the negative impact of higher rates on corporate earnings; the regional financial system is more resilient thanks to consolidation and M&A; foreign investors still have room to add positions, and Japanese households' roughly ¥2,200 trillion in assets are also increasing their equity allocation. At the sector level, financials benefit from higher rates. AI semiconductors may face short-term pressure from yield shocks, but their growth logic is embedded in global supply chains and depends mainly on U.S. yields and AI industry risks rather than Japanese yields themselves.

Analysis framework

The report uses a combination of macro interest rate analysis, fiscal policy analysis, exchange rate analysis, sector balance sheet analysis, and staged comparisons of historical market performance. At the macro level, it compares Japan and U.S. 10-year yield trends, oil prices, and inflation pressure; on the fiscal side, it estimates the impact of a supplementary budget, food consumption tax relief, and cash handouts on the primary balance-to-GDP ratio; at the sector level, it uses the ratio of interest-bearing debt to total assets to measure rate sensitivity and reviews sector performance since 2023 during periods of rising yields and yen depreciation.

Methodology notes

• macro_strategyyield_regime_analysis

  Yield regime analysis

  Treats a roughly 3% 10-year JGB yield as the core scenario for Japan equities entering a new rate environment, and distinguishes between the yield level itself and the speed of the move when assessing the impact on asset prices.

• fiscal_analysisprimary_balance_impact

  Primary balance impact assessment

  Estimates the impact of the supplementary budget, consumption tax relief, and cash handouts on the primary balance-to-GDP ratio to judge whether fiscal policy could trigger a systemic sell-off in Japanese assets.

• sector_strategybalance_sheet_rate_sensitivity

  Balance sheet rate sensitivity

  Measures the impact of rising rates on corporate interest burdens by looking at the ratio of interest-bearing debt to total assets, and uses that to distinguish rate-sensitive sectors such as real estate and electric power & gas from lower-sensitivity sectors such as electronics & precision instruments, pharmaceuticals, and telecommunications & services.

• market_historysector_performance_during_rising_yields_and_yen_depreciation

  Sector performance review during rising yields and yen depreciation

  Reviews several phases since 2023 in which Japanese yields rose rapidly and the yen depreciated, and examines the relative performance versus TOPIX of banks, financials, energy resources, electric power & gas, machinery, and AI semiconductors.

Asset mapping & comparison

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

• Japanese equities

  core allocation target

  Strengths

  The risk of yen appreciation is lower, overseas investors still have room to buy, retail equity allocation is increasing, and the two large weight sectors of financials and AI semiconductors provide support.

  Weaknesses

  A rapid rise in long-term yields raises discount rates and intensifies pressure on fiscal and financial systems.

  Comparison

  Compared with bonds and the yen, the report believes a supplementary budget alone is unlikely to cause a triple sell-off in stocks, bonds, and the yen.

  Risks

  Persistently high oil prices, larger fiscal spending, and yields rising too quickly into the 3.0%-3.5% warning range.

• financial stocks

  beneficiary of rising rates

  Strengths

  Rising yields usually improve the relative performance of financials, and banks and non-bank financials have shown strength during periods of rising yields and yen depreciation.

  Weaknesses

  Regional financial institutions may come under pressure in the 3.0%-3.5% yield range if capital levels are affected by bond valuations or holdings.

  Comparison

  Compared with AI semiconductors, financials benefit more directly from rising domestic Japanese yields.

  Risks

  Capital pressure at regional banks, deteriorating fiscal confidence, and yields rising too quickly.

• AI semiconductors

  growth theme and important market weight

  Strengths

  Lower debt ratios reduce the direct negative impact of higher Japanese yields, and global AI supply-chain demand still supports earnings.

  Weaknesses

  Valuations are more sensitive to U.S. long-term yields and U.S. hyperscaler valuations.

  Comparison

  Historically, AI semiconductors have outperformed TOPIX during most of the rapid yield increase phases in Japan since 2023, and even in weaker periods they have roughly matched it.

  Risks

  A sharp rise in U.S. yields, AI power constraints, regulation, pricing pressure, and external shocks such as Middle East conflict.

• 10-year JGB

  key macro variable

  Strengths

  A 3% level is not inconsistent with Japan's 2030 potential growth and 2% inflation target.

  Weaknesses

  The recent pace of the rise has been too fast, and fiscal news and oil shocks have amplified market concerns.

  Comparison

  The report notes that Japanese yields may have moved before U.S. yields and could spill over into global markets.

  Risks

  Breaking above the 3.0%-3.5% warning range, fiscal expansion exceeding expectations, and oil prices remaining elevated.

• yen

  earnings offset variable

  Strengths

  Yen depreciation improves Japanese corporate earnings and partly offsets the negative impact of higher yields.

  Weaknesses

  Yen depreciation also reflects imported inflation pressure, which may push up import prices and long-term rates.

  Comparison

  Compared with past scenarios in which rising yields were accompanied by yen appreciation, this round of yen depreciation makes the pressure on equities relatively manageable.

  Risks

  An exchange-rate reversal weakening earnings support, or further depreciation aggravating imported inflation.

• highly leveraged sectors such as real estate, electric power & gas, and transportation & logistics

  rate-sensitive pressure sectors

  Strengths

  Some electric power & gas companies have historically performed well during periods of rising yields and yen depreciation.

  Weaknesses

  A high share of interest-bearing debt means rising rates increase interest expense burdens.

  Comparison

  Compared with electronics & precision instruments, telecommunications & services, pharmaceuticals, and machinery, highly leveraged sectors are more sensitive to rising yields.

  Risks

  Higher financing costs, weaker demand due to high oil prices, and deteriorating consumer confidence.

Key data

• Warning range for 10-year JGB yields3.0%-3.5%The report sees this range as the warning level at which the regional financial system may come under pressure on capital levels.
• J.P. Morgan year-end 10-year JGB yield forecast2.95%The report believes a medium-term move into the 3% yield range is not surprising, but the recent pace of the rise has been too fast.
• J.P. Morgan year-end 10-year UST yield forecast4.55%AI semiconductor valuations are more sensitive to U.S. long-term yields, and the report expects U.S. long-term yields to be roughly flat by year-end.
• Impact of the supplementary budget on the primary balance/GDPabout -0.5 percentage pointsAssuming an increase of ¥2-3 trillion in contingency funds, this could delay the achievement of a primary surplus from FY2026 to FY2027-28.
• Impact of the supplementary budget plus food consumption tax reliefabout -1 percentage pointThe drag on fiscal balance would be more pronounced, but the report still emphasizes the need to confirm the exact size of fiscal spending.
• Potential cash handout plan¥50,000 per personIf implemented, this could further lower the primary balance/GDP ratio by more than 1 percentage point; the report says the market is not seriously pricing in this scenario at present.
• Household assets in Japanabout ¥2,200 trillionThe report sees retail investors increasing equity exposure as one source of support for Japanese equities.
• Weights of financials and AI semiconductors in TOPIX market capabout 20% eachThe report sees financials and AI semiconductors together as an important support for the Japanese market's upside.
• Brent oil price forecastcurrently above $110/bbl, around $95/bbl at year-endIf Middle East tensions ease and oil prices fall, Japanese yields may stabilize in the short term.

Impact & implications

In investment terms, an environment of rising yields and yen depreciation is more favorable for sectors such as banks, financials, energy resources, electric power & gas, and machinery; real estate, electric power & gas, air transportation, and other highly leveraged industries face greater pressure. Although AI semiconductors fell early on during Japan's recent rapid yield increases, historically they have still outperformed or at least matched TOPIX during most periods of rapid yield increases in Japan, so the report does not believe rising Japanese yields will directly end the AI rally. The more important risk variables are whether higher U.S. yields will compress U.S. hyperscaler valuations and the AI sector's own power, regulatory, and pricing issues.

Risks

• If the 10-year JGB yield rises quickly to or above 3.0%-3.5%, the regional financial system may face capital pressure.
• If the supplementary budget, food consumption tax relief, or the ¥50,000 per person cash handout exceeds expectations in scale, it could significantly drag on the primary balance and raise concerns about fiscal sustainability.
• Persistently high oil prices will intensify Japan's imported inflation, suppress final demand, and push long-term yields higher.
• If U.S. long-term yields rise sharply, they could compress U.S. hyperscaler valuations and transmit to the P/E multiples of Japanese AI semiconductor stocks.
• The AI industry faces power supply constraints, regulatory risks, and pricing pressure, which could weaken earnings expectations for companies linked to the global AI supply chain.
• Highly leveraged sectors face rising interest burdens and valuation compression risk in a higher-rate environment.

What to watch

• Whether the 10-year JGB stabilizes around 3% or moves closer to the 3.0%-3.5% warning level for the regional financial system.
• The final size of Japan's supplementary budget, the FY2027 budget, food consumption tax relief, and any cash handout plan.
• Whether Brent crude falls from above $110/bbl to around $95/bbl by year-end, easing imported inflation and yield pressure.
• The USD/JPY trend and the dual impact of yen depreciation on corporate earnings and import inflation.
• Whether capital inflows from overseas investors and Japanese retail investors into Japanese equities continue.
• Changes in the U.S. 10-year Treasury yield and valuations of major U.S. tech companies tied to AI.
• Progress on consolidation and M&A among regional financial institutions and their ability to withstand a high-yield environment.
