Japanese bank stocks refocus on medium-term ROE targets, with attention on upside in P/B valuations
Goldman Sachs believes that major and mid-sized Japanese banks raising ROE targets in their new medium-term plans, combined with BOJ rate hike expectations and expanding demand for financial services, could further lift bank stock P/B multiples.
- Medium-term plan targets for multiple banks for FY3/29 indicate net profit CAGR of about 8%-25% over the next three years, and most plans assume only policy rates of about 0.75%-1.25% or an additional 0-2 rate hikes.
- Large banks' ROE targets have shifted up from the previously common 10%-12% range to above 12%, and some banks have further disclosed medium- to long-term targets, aiming for the ROE levels of top global banks.
- Among major regional banks, Resona HD targets 12% ROE under a 1.0% policy rate assumption and 14% ROE under a 1.5% policy rate assumption; Shizuoka FG also proposed a mid-teens ROE target for FY2030.
- The report links ROE with P/B, arguing that if ROE rises toward medium-term and medium- to long-term targets, higher P/B multiples for bank stocks could be unlocked if the external environment remains unchanged.
Report interpretation
Overview
This report focuses on the medium-term plans updated by the Japanese banking sector in the latest earnings season, especially ROE targets, profit growth paths, and the resulting potential upside in P/B valuations. The report points out that as the market pays more attention to the BOJ rate hike outlook, bank stock investors are reexamining the profitability targets in each bank’s medium-term plan. FY3/29 plans from major and mid-sized banks generally point to strong profit growth even though their interest rate assumptions are relatively conservative.
Core views
The core view is that earnings growth in Japan’s banking sector depends not only on widening loan-deposit spreads driven by higher domestic interest rates, but also benefits from broader demand for financial functions, including domestic financing demand, active capital markets, corporate restructuring and business succession, growth in cashless payments, and asset management product demand arising from the shift from savings to investment. ROE is an important factor affecting bank stock valuations, and if banks can deliver on their medium-term and medium- to long-term ROE targets, P/B multiples may continue to rise.
Analysis framework
Based on new medium-term plans or KPI updates disclosed by major Japanese banks and major regional banks, the report compares each bank’s medium-term ROE targets, medium- to long-term ROE targets, policy rate assumptions, and profit growth drivers, and assesses potential valuation upside through the relationship between ROE and P/B. The report also uses current P/E and company-disclosed ROE targets to estimate P/B levels under different target ROEs.
Methodology notes
P/B can be decomposed as a function of ROE and cost of equity
The report uses ROE targets and current P/E to infer potential P/B levels, emphasizing that, all else equal, higher ROE usually corresponds to higher P/B multiples.
Comparison across four attributes: Growth, Financial Returns, Multiple, and Integrated
Goldman Sachs’ factor profile compares a stock’s position versus the market and industry peers through growth, financial returns, valuation multiples, and integrated indicators; for financial stocks, financial returns mainly use ROE, while valuation multiples mainly use P/E, P/B, and P/D.

Asset mapping & comparison
Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).
- Major Japanese banksCore beneficiary assets in the sector
- Strengths

- Weaknesses
- It needs to prove that a resilient business mix can translate into sustained valuation improvement.
- Comparison
- The target has been revised up from above 10% to above 12%, with a clearer valuation ambition.

Impact & implications
If Japanese banks can raise ROE as planned, and if the external environment, cost of equity, and valuation parameters do not materially worsen, bank stock P/B multiples may continue to be re-rated. For investors, the key going forward is to distinguish which banks’ ROE improvements come from sustainable business expansion and which mainly rely on rising interest rates; it is also necessary to track each bank’s strategic execution, portfolio adjustments, capital markets business growth, and changes in interest rate scenarios.
Risks
- The number of BOJ rate hikes or the policy rate level may fall short of assumptions in banks’ medium-term plans, causing loan-deposit spread expansion to underperform expectations.
- A rising cost of equity, falling global bank valuations, or increasing macro risks may weaken the boost from higher ROE to P/B.
- Capital markets, investment banking, S&T, and asset management businesses are cyclical and may cause earnings volatility.
- Regional banks face regional economic, loan demand, deposit competition, and asset quality risks.
- Some banks’ medium- to long-term ROE targets are relatively high, and there is uncertainty around execution paths, capital allocation, and business mix adjustments.
What to watch
- Quarterly progress of each bank’s medium-term plan ROE targets and management updates.
- The BOJ policy rate path, changes in short-end and long-end interest rates, and pass-through to deposit costs.
- Evidence of large banks such as MUFG, SMFG, and Mizuho progressing toward ROE targets above 12% or in the mid-teens.
- The ability of major regional banks such as Resona HD and Shizuoka FG to deliver ROE under different interest rate assumptions.
- Japan Post Bank’s Japanese government bond portfolio restructuring, PE, and foreign bond investment trust performance.
- Whether higher ROE translates into higher P/B, and whether P/E, cost of equity, and the external market environment remain stable.
