SKN | Bank of London Losses Near £190 Million: What the Numbers Reveal About Banking Counterparty Risk

Key Takeaways

• The Bank of London’s continuing losses highlight why HNWI should assess the sustainability of a banking institution, not simply its regulatory capital ratio.
• The bank reported a £27 million loss before tax for 2025, while cumulative losses at group level have approached £190 million, increasing the importance of shareholder funding and execution.
• For internationally mobile families, operational resilience, governance and uninterrupted access to liquidity should be treated as core components of wealth preservation.
• A diversified banking architecture can reduce dependence on any single institution without creating unnecessary complexity across jurisdictions.

The Bank of London’s financial position provides a useful reminder that banking risk is rarely captured by a single balance-sheet statistic. The UK clearing bank reported a £27 million loss before tax for 2025, compared with a £46.5 million loss in 2024. At group level, accumulated losses have moved toward £190 million. At the same time, the institution has secured additional shareholder funding and continues to invest in its banking infrastructure, governance and risk controls.

Why Profitability Matters Even When Capital Ratios Look Strong

Bank of London reported a Common Equity Tier 1 ratio of 173.23% at the end of 2025, up from 96.07% a year earlier. On the surface, that appears exceptionally strong. The more relevant question for sophisticated clients, however, is what sits behind that ratio and how long the institution can sustain its operating model.

The bank’s total income increased 77% to approximately £6.4 million in 2025, while operating expenses declined by 33%. Yet the business remained materially loss-making. Management attributes the deficit to investment in infrastructure and expertise, remediation of legacy issues and the withdrawal from unprofitable operations.

For an HNWI, this distinction is important. A strong regulatory ratio can demonstrate substantial capital relative to risk-weighted assets without proving that a banking business has reached sustainable profitability. The quality and durability of the institution’s funding model therefore deserve separate scrutiny.

Governance Is Part of Counterparty Due Diligence

The Bank of London case is particularly relevant because financial performance is only one part of the story. In March 2026, the UK’s Prudential Regulation Authority fined the bank and its parent company £2 million after finding failures involving regulatory capital reporting, transparency and financial resources. The regulator said the underlying breaches warranted a £12 million penalty but reduced the amount because payment at that level would have caused serious financial hardship.

The episode reinforces a principle familiar to experienced private bankers: governance quality can become a financial variable. For wealthy families, the question is not merely whether an institution is licensed. It is whether management information, compliance infrastructure, regulatory reporting and internal controls are sufficiently robust to protect the institution during periods of stress.

Build Banking Redundancy Before It Becomes Necessary

The practical response for globally mobile families is not to avoid smaller or newer financial institutions automatically. It is to determine which functions can safely be concentrated and which require redundancy.

A Swiss private bank in Zurich or Geneva may provide custody, discretionary wealth management, succession planning and consolidated reporting. A separate institution can handle operating liquidity, payments or jurisdiction-specific requirements. This creates functional diversification without forcing the family to maintain numerous overlapping relationships.

The objective is controlled redundancy. If one institution experiences regulatory restrictions, technology disruption, funding pressure or an unexpected change in strategy, essential liquidity and custody arrangements should remain accessible elsewhere.

Stress-Test the Structure, Not Just the Portfolio

HNWI should periodically test the practical mechanics of their banking structure. Can essential payments continue if one bank temporarily restricts an account? Can liquidity be accessed in another currency? Are custody assets clearly separated from operating cash? Would a change in tax residence create additional documentation or onboarding requirements? Who has authority to move assets if a principal is unavailable?

These questions are particularly important for entrepreneurs and families operating across several jurisdictions. Wealth preservation depends not only on investment performance, but also on reliable access, governance and operational continuity.

The Bank of London experience therefore offers a broader lesson: the strongest private banking structure is not necessarily the one with the largest institution or the highest headline capital ratio. It is the structure designed so that no single banking relationship becomes indispensable.
