BOJ rate-hike expectations and AI-stock pullback jointly supported stronger performance of Japanese bank stocks

Overview

This report is Nomura's monthly tracking note on the Japanese bank sector, focusing on BOJ monetary policy, market rate movements, bank-stock relative performance, valuation, loan and deposit data, credit-demand surveys, and macro indicators. It notes that Japanese bank stocks rose in early June on BOJ rate hike expectations, temporarily weakened after the policy rate was raised to 1% on June 16, then rebounded after the June 24 hawkish policy summary and renewed expectations for further tightening.

Core views

The central view is to remain bullish on Japanese banks. Supporting factors include continued progress in BOJ policy normalization, rising expectations for additional rate hikes, higher Japanese government bond yields, a robust earnings base for banks, and some fund rotation into the banking sector after a pullback in AI-related stocks. Nomura's base case judges the next BOJ hike at end-2026, with a primary scenario of December 2026; however, if the BOJ becomes more concerned about lagging the market curve and wants to avoid a sudden tightening shock, the next hike could also come as early as autumn 2026.

Analysis framework

The report combines a top-down approach with industry data tracking: it first assesses policy and macro catalysts such as BOJ meetings, policy summaries, the government's basic policy draft, Japanese bond yields, and U.S. labor data, then integrates bank-sector relative performance versus TOPIX, valuation, performance of major banks and regional banks, loan balances, lending rates, credit demand, trust balances, syndicated loans, bankruptcies, CPI, and corporate goods price index data to determine sector direction.

Methodology notes

• Macroeconomic policy analysisBOJ rate-hiking cycle assessment

  Assess the timing of rate hikes using BOJ meetings, policy summaries, government policy statements, and inflation and interest-rate signals.

  Nomura uses end-2026, especially December 2026, as the base case for the next hike, while viewing an earlier hike in autumn 2026 as a risk scenario.

• Relative performance analysisBank stock relative performance versus TOPIX

  Use the excess performance of the banking sector relative to TOPIX to gauge market pricing of rate hikes and earnings improvement.

  The report highlights that Japanese bank stocks outperformed TOPIX by 6.2% over the past month, indicating clear support for the sector from policy expectations and fund rotation.

• Industry fundamental trackingLoan, deposit, credit demand, and rate data monitoring

  Use BOJ statistics, bank loan data, lending rates, and credit-demand surveys to judge the bank income environment.

  The report presents extensive charts tracking loan balances, lending rates, loan demand, investment trusts, syndicated loans, and commitment lines to evaluate the banking operating environment.

Asset mapping & comparison

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

• Japanese bank stocks

  Core beneficiary asset

  Strengths

  Benefit from BOJ rate-hike expectations, higher JGB yields, resilient bank earnings, and fund rotation from AI-related stocks.

  Weaknesses

  The sector has accumulated strong gains in the near term and has lacked sufficient profit-taking, so a pace adjustment could occur.

  Comparison

  Over the past month, bank stocks outperformed TOPIX by 6.2%, clearly beating the broad market.

  Risks

  If BOJ hikes are delayed, rates fall, or policy language shifts dovishly, the sector's catalysts may weaken.

• Major banks and major regional banks

  Main watchlist within the sector

  Strengths

  Rising rates typically improve loan yields and support net interest income expectations.

  Weaknesses

  Regional banks are more sensitive to regional loan-demand conditions, deposit-cost dynamics, and changes in credit quality.

  Comparison

  The report presents stock performance of major banks and major regional banks, along with relative performance against the banking sector.

  Risks

  If loan demand weakens, corporate bankruptcies rise, or credit costs worsen, earnings optionality could come under pressure.

• AI-related stocks

  Rotational peer asset for tracking flows

  Strengths

  Previously attracted high market attention and was one of the crowded areas of capital flows.

  Weaknesses

  They have shown a clearer pullback since late June.

  Comparison

  The pullback in AI-related stocks has diverted some capital to banks with more stable earnings.

  Risks

  If AI-related stocks recover strongly, relative fund flows into bank stocks may weaken.

Impact & implications

For investors, the implication is that Japanese bank stocks remain a beneficiary under a rising-rate environment and expectations of policy normalization. If BOJ's tightening path stays clear, net interest margin and earnings expectations may continue to support valuation; if AI-related stocks keep pulling back, fund rotation may further benefit bank stocks. However, the sector has already posted sustained strong performance, and with insufficient profit-taking after the June hike confirmation, there is near-term risk of a pace adjustment.

Risks

• The timing of the BOJ's next hike coming later than market expectations, weakening the rate-upside catalyst for bank stocks.
• Bank stocks may face a short-term pace adjustment because there has not yet been obvious profit-taking after June's hike confirmation.
• US long-term yields, US employment data, or changes in foreign central bank policies may affect Japanese rates and risk appetite for financial stocks.
• If Japanese CPI or corporate goods prices miss the upside, market confidence in further BOJ tightening may decline.
• If wording on monetary policy in the basic policy document raises concerns about policy intervention, the banking sector could face temporary headwinds.
• Weakening loan demand, rising corporate bankruptcies, or deterioration in credit costs could offset the earnings benefits from rising rates.

What to watch

• Subsequent BOJ meetings, policy summaries, and committee statements on the risk of falling behind the policy curve.
• Japanese CPI data for summer 2026 and transmission of corporate goods prices into consumer inflation.
• Whether Japanese government bond yields remain elevated, especially the impact of long-end rates on bank valuations.
• US monetary policy stance and statements by the Federal Reserve Chair on global rate expectations.
• Whether AI-related stocks continue to pull back and whether flows continue to move into the banking sector.
• Changes in major and regional bank loan growth, lending rates, deposit costs, and credit quality.
