The Data Center as the New Vault: Infrastructure Considerations for Modern Trust Administration
Trustees today navigate fiduciary responsibilities originally conceived when custody meant physical control and privacy was defined by jurisdictional boundaries. The digital transformation of trust administration has fundamentally altered this landscape, creating new considerations for data governance that merit careful examination.
The infrastructure supporting modern trust operations—data processing, decision-making systems, and record keeping—increasingly relies on third-party platforms operating across multiple jurisdictions under varying regulatory frameworks. This evolution raises important questions about control, oversight, and fiduciary responsibility that trustees must address thoughtfully.
In July 2025, the World Economic Forum highlighted a critical shift in the geopolitical landscape: "Data centres are now critical infrastructure in the global digital economy... Once viewed as back-end infrastructure, data centres have evolved into strategic assets – the digital age's equivalent of power plants or ports." The implication for trustees is direct: where trust data resides—and under whose regulatory framework—increasingly defines the capacity to fulfill fiduciary duties with certainty and transparency.
Infrastructure as a Fiduciary Instrument
The relationship between infrastructure control and fiduciary oversight has grown more complex as trust administration becomes increasingly digitized. Modern trustees must evaluate infrastructure choices not merely as operational decisions, but as fundamental components of their fiduciary framework.
The WEF analysis notes that "Governments from the European Union to China are implementing laws to keep sensitive data within their borders, fragmenting the once-borderless cloud into national silos. In this environment, countries fear that allowing data to be processed abroad could expose them to surveillance or foreign leverage, entwining technology with national security."
For trustees, this fragmentation creates both challenges and opportunities. The choice of infrastructure architecture must align with legal obligations, regulatory expectations, and the specific requirements of client relationships across multiple jurisdictions.
Operational Realities in Modern Trust Administration
Trust companies increasingly encounter situations where infrastructure choices directly impact their ability to meet regulatory and fiduciary obligations:
Regulatory Compliance Pressures:
FCA PS21/3 requires demonstrable operational resilience over critical services, including clear visibility into third-party dependencies
The Trustee Act 2000 Section 11 imposes duties to properly oversee all delegated functions, extending to infrastructure providers
GDPR Article 28 mandates specific contractual arrangements and oversight mechanisms for data processors
Cross-border legal proceedings increasingly require rapid access to complete audit trails and data processing records
Practical Manifestations:
Audit Response Delays: Trust companies experiencing delayed responses to regulatory queries due to vendor-controlled logging systems and data access procedures
Jurisdictional Uncertainty: Legal ambiguity over data location and applicable law in cross-border disputes or regulatory investigations
AI Explainability Gaps: Automated decision-making systems generating fiduciary recommendations without sufficient transparency for regulatory scrutiny
Compliance Breach Risk: Unintentional violations of data protection regulations due to insufficient visibility into international data flows
These challenges reflect not failures of technology, but misalignments between infrastructure architecture and fiduciary requirements. The solution lies in more thoughtful architectural design that prioritizes transparency, control, and regulatory alignment alongside operational efficiency.

Final Thoughts
Infrastructure decisions in modern trust administration represent fundamental choices about risk, control, and strategic positioning rather than merely operational considerations. The digitization of fiduciary services demands that trustees approach infrastructure architecture with the same rigor applied to investment policy and regulatory compliance frameworks.
The choice between cloud, sovereign, or hybrid infrastructure models must align with each institution's regulatory environment, risk appetite, operational capabilities, and strategic objectives. There is no universal solution—only architectures that are more or less aligned with specific fiduciary requirements and institutional contexts.
As the World Economic Forum notes, "The age of technological rivalry is here, but whether data centres become targets of conflict or backbones of a connected global economy will depend on choices made now by policy-makers and industry leaders." For trustees, these choices extend beyond technology to encompass fundamental questions of fiduciary stewardship in an increasingly complex global environment.
Successful trustees will be those who recognize infrastructure not merely as operational support, but as fiduciary infrastructure—a critical component of their ability to fulfill duties of care, loyalty, and prudence in an increasingly digital world. The institutions that thoughtfully align their technological architecture with their fiduciary responsibilities will be best positioned to serve clients effectively while maintaining regulatory confidence and competitive advantage.
The path forward requires neither defaulting to convenience nor pursuing control for its own sake, but rather designing infrastructure architectures that serve the deepest principles of fiduciary duty while embracing the operational advantages that modern technology can provide.
