Institutional Investor Stewardship in Corporate Governance

Summary

Institutional investors have increasingly embraced stewardship as a central pillar of corporate governance, recognising that their role extends beyond capital allocation to active engagement with investee companies. This stewardship paradigm encompasses dialogue with boards, voting on shareholder resolutions and public advocacy to foster long-term value creation. Underpinning this shift are stewardship codes and regulatory reforms—most notably in the UK and EU—that encourage transparent policies on engagement and accountability. The stewardship function intersects with environmental, social and governance (ESG) integration, as investors seek to mitigate systemic risks and align corporate strategy with broader societal objectives. Drawing on agency and stewardship theories, research reveals that effective investor stewardship can strengthen board oversight, reduce short-termism and enhance corporate resilience. Yet the practice varies globally, shaped by national legal frameworks, market expectations and the prevalence of soft-law instruments. Against a backdrop of rising passive investment and growing scrutiny of fiduciary duties, the evolving stewardship landscape holds profound implications for corporate behaviour, financial stability and sustainable development.
