Evaluating valuation discounts across London-listed financial institutions, CET1 buffers, return on tangible equity and rate-cut sensitivity.
Executive Overview
Major UK banking groups listed on the London Stock Exchange (LSE) entered 2026 with strong capital positions, improving profitability, and continued capacity for shareholder distributions. However, the valuation picture has changed materially from earlier periods when UK bank shares frequently traded at substantial discounts to tangible book value.
According to the Bank of England’s July 2026 Financial Stability Report, major UK banks generated an aggregate underlying Return on Tangible Equity (RoTE) of 15.3% in Q1 2026. Their average price-to-tangible-book ratio had recovered to around 1.7x, close to the highest levels observed since the Global Financial Crisis. Major banks also maintained an aggregate CET1 capital ratio of 14.2% in Q1.
These figures suggest that the sector can no longer be characterized simply as a deep-value trade below tangible book. Instead, the key analytical question is whether current valuations are supported by sustainable profitability, structural hedge income, credit quality, capital generation, and shareholder distributions.
This paper applies the Origin Core · UK Financial Value framework to examine those factors across major UK banking groups.
1. Tangible Book Valuation and Profitability
Bank valuations are closely connected to the relationship between profitability and the cost of equity.
When a bank sustainably generates a Return on Tangible Equity above the return investors require for bearing equity risk, it can reasonably trade above tangible book value. Conversely, banks expected to earn returns below their cost of equity tend to trade at discounts.
Price-to-Tangible Book (P/TBV) = Market Capitalization / Tangible Common Equity
The current UK market illustrates this relationship more clearly than the deep-discount environment seen during and after the pandemic.
The Bank of England reported that major UK banks’ average P/TBV ratio recovered to approximately 1.7x by mid-2026, after temporarily declining in March amid geopolitical uncertainty and concerns around private-credit exposures. This level was around the highest observed since the Global Financial Crisis.
At the same time, aggregate underlying RoTE reached 15.3% in Q1 2026, while consensus expectations cited by the Bank suggested returns could remain somewhat above that level over the coming years.
Company results illustrate the dispersion within the sector:
| Metric | Lloyds Banking Group H1 2026 | NatWest Group H1 2026 |
|---|---|---|
| RoTE | 17.1% | 19.7% |
| CET1 Ratio | 13.1% pro forma | 13.2% |
| Profit | £3.1bn statutory PAT | £3.0bn attributable profit |
Lloyds reported net income of £9.7 billion and statutory profit after tax of £3.1 billion during the first half of 2026, while NatWest reported £3.0 billion of attributable profit and a 19.7% RoTE.
These figures support a strong profitability picture, but higher market valuations also mean that investors must now place greater emphasis on earnings sustainability rather than relying on a simple re-rating from depressed book-value multiples.
2. Net Interest Income and the Structural Hedge
Interest-rate sensitivity remains a central issue in UK bank analysis.
As deposit rates, mortgage pricing and central-bank policy change, net interest margins can move materially. However, large UK retail banks use structural hedges to reduce the immediate effect of interest-rate movements on earnings.
A structural hedge generally involves investing portions of stable, low- or non-interest-bearing deposits and equity into fixed-rate assets or interest-rate swaps over multiple years. This can smooth changes in net interest income as interest rates rise or fall.
Lloyds provides a clear example. At the end of March 2026, its sterling structural hedge had a notional balance of approximately £246 billion, with an average life of around 3.75 years. The hedge generated approximately £1.6 billion of income in Q1 2026, compared with £1.2 billion in the same period a year earlier. Lloyds expected structural hedge income to exceed £7 billion for 2026 and £8 billion in 2027.
The impact is visible in margins. Lloyds reported a banking net interest margin of 3.17% in Q1 2026, with the structural hedge contributing positively even as competitive mortgage pricing created pressure elsewhere in the balance sheet.
NatWest shows a similar mechanism. Its structural hedge generated approximately £2.97 billion of total income in H1 2026, compared with £2.12 billion in H1 2025. The period-end hedge notional had increased to around £203 billion.
Structural hedges do not eliminate interest-rate risk. They delay and redistribute the transmission of rate changes through bank earnings. Their value therefore depends on hedge maturity profiles, reinvestment rates, deposit behavior, and the wider composition of each bank’s assets and liabilities.
3. Capital Strength, Credit Quality, and Stress Resilience
Capital remains one of the strongest features of the current UK banking system.
The Bank of England reported an aggregate 14.2% CET1 ratio for major UK banks in Q1 2026, alongside a liquidity coverage ratio of approximately 142% in May. The proportion of major-bank loans classified as IFRS 9 Stage 2 declined to 8.5%, while overall provision coverage remained broadly stable.
The Financial Policy Committee has stated that an appropriate benchmark for system-wide Tier 1 requirements is around 13% of risk-weighted assets, broadly equivalent to a CET1 ratio of around 11%.
The Bank of England’s 2025 Bank Capital Stress Test provides further context. Under a severe hypothetical macroeconomic shock, the aggregate CET1 ratio of participating banks declined from 14.5% to a low point of 11.0%, while remaining above aggregate regulatory minima and systemic buffers. No individual bank was required to strengthen its capital position as a result of the test.
This should not be interpreted to mean that dividends or buybacks would remain unchanged in a severe downturn. Stress resilience partly reflects banks’ ability to adjust distributions and take management actions when conditions deteriorate.
At individual-bank level, Lloyds reported a pro-forma CET1 ratio of 13.1% at June 2026, while NatWest reported 13.2%.
The relevant Origin Core question is therefore not simply whether a bank exceeds its regulatory minimum, but how much distributable capital remains after accounting for expected credit losses, regulatory buffers, growth requirements and potential conduct costs.
4. Shareholder Returns and Valuation Discipline
Strong capital generation has allowed major UK banks to continue returning capital through dividends and share repurchases.
The Bank of England reported that major UK banks returned approximately £7.7 billion to shareholders through dividends and buybacks in Q1 2026, broadly consistent with their recent average.
Lloyds provides a current example. Its H1 2026 results included approximately £1.9 billion of total capital returns, comprising a higher interim dividend and a newly announced £1 billion share-buyback programme. The group also stated that it expected to manage toward a CET1 ratio of approximately 13% by year-end 2026.
Share repurchases can increase earnings and tangible book value per remaining share when executed at suitable valuations, but the effect is not automatically value-accretive at every market price.
When banks trade materially above tangible book value, analysts must consider whether the expected return on repurchased shares remains attractive relative to alternative uses of capital, including business investment, lending growth, acquisitions, and dividends.
For this reason, the earlier assumption that UK banks automatically create substantial tangible-book accretion by repurchasing shares at deep discounts is no longer appropriate for the sector as a whole.
Under Origin Core Layer 3, relevant valuation indicators now include:
Price-to-tangible-book value
Sustainable RoTE relative to cost of equity
Net interest income durability
Structural hedge contribution
CET1 capital generation
Credit-loss trends
Dividend and buyback capacity
Regulatory and conduct-related liabilities
Research Implications
The investment case for major UK banks has evolved.
Earlier periods of deep tangible-book discounts have given way to considerably stronger valuations. By mid-2026, major UK banks were trading at an average price-to-tangible-book ratio of around 1.7x, supported by improving profitability, structural hedge income, capital strength and shareholder distributions.
This does not remove the sector’s analytical appeal, but it changes the nature of the valuation question.
Under the Origin Core · UK Financial Value framework, the focus should now be on whether banks can sustain RoTE in the mid-to-high teens, preserve asset quality, maintain capital generation, and continue shareholder distributions at valuations already reflecting a significant degree of improved performance.
For SMA’s research process, UK banking majors therefore remain useful examples of how profitability, interest-rate management, capital resilience and market valuation interact across changing monetary cycles.
