Codes, convergence, and where real boards go beyond the rulebook

Corporate governance has evolved from a niche academic topic to a mainstream discipline that shapes how companies create value, manage risk, and earn investor trust. Behind every governance framework lie three practical questions: which philosophy of governance truly works, how national codes differ in practice, and whether companies today are merely complying with rules or actively using governance as a competitive advantage.
A quick survey of major governance codes shows both diversity and convergence. The UK Corporate Governance Code remains one of the clearest examples of a principle-based regime, using “comply or explain” to encourage thoughtful disclosure, strong board effectiveness, structured evaluations, and transparent remuneration practices. Germany’s Corporate Governance Code reflects its distinctive two-tier board structure, combining legally binding rules with recommendations and suggestions that emphasise supervisory oversight and codify the interaction between management, shareholders, and labour. Japan’s Corporate Governance Code focuses on improving board independence, board effectiveness, and investor dialogue, addressing historical challenges of insider-driven boards and cross-shareholding. Singapore’s Code blends principles and explicit provisions, with particular attention to technology risk and market integrity in its role as a global financial hub. Overarching all of these, the G20/OECD Principles continue to serve as the global reference point, defining the essential elements of transparency, accountability, equitable treatment of shareholders, and consideration for stakeholders.
These codes reveal much about the societies in which they are embedded. Differences reflect institutional architecture, such as whether countries use unitary or two-tier boards, as well as market structures, from bank-dominated systems to highly dispersed shareholder bases. Yet a common core runs through all of them: independent oversight, transparent reporting, robust risk management and internal controls, and an emphasis on board effectiveness. This shared foundation is the clearest sign of global governance convergence.
The debate between principles-based governance and prescriptive, rules-based governance remains central. Rules offer certainty, reduce ambiguity, and make enforcement easier. This is the logic behind the U.S. Sarbanes-Oxley Act, which articulates clear and mandatory requirements for internal controls, auditor attestation, audit committee independence, and financial expertise. Principles, on the other hand, allow companies to tailor governance to their strategies and contexts. They focus on outcomes rather than processes and rely on transparent disclosure and active market discipline. The UK and OECD approaches exemplify this model, encouraging boards to explain how they apply principles to create long-term value.
In practice, the world is moving toward a hybrid. Regulators increasingly codify a small number of non-negotiable rules, particularly around financial reporting, internal controls, and audit committee structure, while leaving broader aspects of board effectiveness, stakeholder engagement, sustainability oversight, and strategy formulation to principles. Investor stewardship bodies such as Federated Hermes amplify this hybrid by imposing expectations through voting policies and engagement, creating an informal enforcement layer that often exceeds regulatory requirements. For these reasons, it is unlikely that the world will converge on a single governance philosophy. Instead, we are witnessing convergence on a core set of enforceable rules, wrapped in a broader ecosystem of principles that allow national and cultural adaptation.
A review of governance disclosures from major global companies demonstrates that many organisations now go significantly beyond the minimum legal requirements. HSBC, Siemens, Toyota, DBS, and Apple all present governance not as compliance text but as part of their strategic narrative. Toyota and DBS explicitly link governance to long-term strategy, sustainability commitments, and technology oversight. DBS’s emphasis on cyber and technology risk oversight reflects the increasing importance of digital resilience, which sits beyond the scope of most traditional governance codes. HSBC and Siemens publish detailed explanations of shareholder engagement, board evaluations, succession planning, and how board discussions shape strategy, clearly exceeding statutory requirements. Apple discloses director skills matrices, independence assessments, and governance guidelines that align with investor expectations rather than minimum legal standards. Across regions, many companies now integrate climate governance into their board reports, connecting risk management, sustainability goals, and board oversight of transition planning.
These examples highlight three ways companies go beyond both law and code. First, they expand the scope of governance to cover emerging risks like technology, AI oversight, and climate, signalling that boards are treating these as strategic responsibilities. Second, they increase transparency, using narrative disclosures to explain not only what governance structures exist but why they exist and how they support long-term value creation. Third, they incorporate investor stewardship into their governance systems, recognising that active investor dialogue is itself a governance mechanism.
Governance today is no longer about ticking boxes but about using oversight, transparency, and board capability to strengthen strategic execution. Codes define expectations, but companies that treat governance as a strategic muscle — rather than a compliance burden — ultimately deliver better performance, build trust, and adapt faster to emerging challenges. As global standards continue to evolve, the most successful boards will be those that adopt the hybrid model: combining a disciplined foundation of rules for financial integrity with a flexible, principle-driven approach to strategy, technology oversight, culture, and sustainability.
