Digital public infrastructure: public rails or private platforms?

Advocates foundational, interoperable, publicly governed digital ID and open systems, conditioned on legal/institutional safeguards and strategic private-sector engagement—not wholesale privatization.

The World Bank Group's 2016 World Development Report advocates for digital public infrastructure—particularly foundational digital ID and open, interoperable systems—as essential for inclusion, transparency, and service delivery, but explicitly conditions its success on strong analog complements (legal frameworks, institutional coordination, privacy safeguards) and strategic engagement with the private sector. It warns against fragmented, vendor-locked, or functionally siloed systems and emphasizes that interoperability, open standards, and public governance are critical to prevent exclusion and ensure scalability—while acknowledging that private-sector-built networks (e.g., mobile) often fill gaps where public backbone infrastructure is weak, necessitating well-structured public-private partnerships.

Advocates public-rail DPI grounded in open standards and interoperable government platforms, permitting private platforms only under strict regulatory guardrails to ensure inclusion and sovereignty.

The World Bank Group's 2021 World Development Report advocates for digital public infrastructure (DPI) built on open, interoperable, and publicly governed systems—especially open standards, open licensing of public data, and government-led interoperability platforms—to ensure inclusion, trust, and the 'once-only' principle for citizens. It emphasizes that while private platforms and public-private data partnerships (e.g., Waze’s Connected Citizens Program or data philanthropy) can play complementary roles, they must be carefully governed to mitigate risks of market asymmetry, conflicts of interest, liability uncertainty, and erosion of public control. Crucially, the WBG stresses that foundational elements like digital ID must be anchored in strong legal frameworks, independent oversight (e.g., data protection authorities), and technical safeguards—never outsourced in ways that compromise sovereignty, security, or equity. Private involvement is conditionally acceptable only when aligned with public interest goals and subject to robust regulation, transparency, and accountability.

Advocates open, interoperable public rails for core DPI functions, permitting proprietary solutions only if they preserve openness, competition, and inclusion.

The World Bank Group advocates for digital public infrastructure (DPI) to be built on open, interoperable 'public rails'—especially in the 'thin waist' (core interfaces like identification, payments, and data exchange)—to ensure inclusivity, competition, and replaceability. While it supports using proprietary technologies where justified by public interest (e.g., advanced patented solutions), it insists such components must not compromise overall system openness or create silos. Success depends on hybrid, principles-based governance: mandating open standards for core connectivity while allowing competitive, innovative private platforms above and below the waist—provided they adhere to national interoperability standards and are subject to complementary policies (competition regulation, data governance, consumer protection).

IMF 2018 reports do not take a position on public rails vs. private platforms for digital public infrastructure.

The IMF's 2018 reports do not explicitly address the question of whether digital public infrastructure (DPI) should be built on public rails versus private platforms, nor do they take a position on interoperability, open systems, or the role of digital ID and payments in that context. While the reports highlight risks of locking into 'proprietary and inflexible technologies' through poor vendor selection and emphasize the importance of government capacity, political commitment, and institutional reform for successful digitalization—including electronic payments and biometric systems—they stop short of advocating for public ownership, open standards, or interoperability mandates as policy principles. The focus remains on fiscal management outcomes and risk mitigation (e.g., cybersecurity, privacy), without prescribing governance models for underlying digital infrastructure.

AIIB 2022 advocates open, publicly governed digital infrastructure rails over private platforms—using innovative public finance and regulation to ensure interoperability, inclusion, and market correction.

In 2022, the AIIB advocated for digital public infrastructure (DPI) to be built on open, interoperable, publicly governed 'rails'—such as wholesale networks, common payment gateways, and regulatory enablers—rather than relying on proprietary private platforms. It emphasized that public instruments (e.g., lowest-subsidy auctions, universal service funds, open-access wholesale networks, regulatory exemptions for community networks) are driving innovation and inclusion where private-sector tools remain static and insufficient to address market failures like the digital divide. The Bank stressed that public financing and regulation must be carefully calibrated—not to displace private investment, but to de-risk and structure markets so that private actors can participate sustainably on open, interoperable foundations. Synergies with other public infrastructure (e.g., energy grids, health/education facilities) were highlighted as essential to cost-effective, inclusive DPI deployment.

ADB 2021 advocates publicly governed, interoperable digital infrastructure with open standards to ensure inclusion and competition, regulating private platforms to prevent monopolistic lock-in.

In 2021, the ADB advocated for digital public infrastructure (DPI) — including digital ID, interoperable payment systems, and shared government platforms — to be built on open, standards-based, publicly governed 'rails' rather than proprietary private platforms. It emphasized that interoperability, adherence to international technical standards (e.g., HL7 FHIR, SNOMED), and avoidance of vendor lock-in are essential to ensure inclusion, competition, and scalability—especially in health and financial services. While acknowledging the convenience of private 'super apps', the ADB warned that unregulated consolidation risks excessive market power and recommended regulatory interventions—including mandated interoperability and data portability—to preserve contestability and consumer welfare. Public investment and regional cooperation were seen as critical to establishing foundational, inclusive DPI where private actors innovate *on top* of shared, sovereign infrastructure.

BIS endorses publicly governed, interoperable digital infrastructure (e.g., CBDCs, FPS) as essential rails—conditioned on real-name ID, central bank stewardship, and regulatory embedding of private providers.

The BIS advocates for digital public infrastructure—such as retail fast payment systems (FPS) and central bank digital currencies (CBDCs)—to serve as foundational, interoperable, and publicly governed 'rails' that enable inclusive, accountable, and privacy-preserving financial services. It emphasizes that such infrastructure must be built on real-name identification, robust data governance, and central bank stewardship to ensure integrity, regulatory oversight, and public accountability—while still allowing private service providers to operate within a sound supervisory framework. Interoperability across domestic and cross-border systems is prioritized, with permissioned distributed ledger technology (DLT) seen as a viable tool when anchored in public governance and legal mandates—not as a replacement for public infrastructure, but as an enabler of it. The BIS explicitly contrasts this approach with private, permissionless crypto platforms, which it deems incompatible with privacy, accountability, and financial integrity.

Favors open, interoperable public digital infrastructure to ensure inclusion and competition, conditioned on regulatory harmonisation, private-sector incentives, and safeguards against data concentration.

The BIS advocates for digital public infrastructure that enables interoperability and inclusion through open, harmonised systems—but stresses that public authorities must design platforms and regulations to ensure a level playing field, prevent data concentration, and incentivise broad participation by private actors. It highlights the importance of cross-jurisdictional coordination, especially for cross-border applications, and supports mandating participation in foundational systems (e.g., fast payments) while preserving space for private-sector innovation. Public rails are preferred where seamless interoperability, regulatory compliance, and financial inclusion are paramount—yet their feasibility depends on technical harmonisation and automation of legacy systems.

BIS supports interoperable, publicly governed digital infrastructure as foundational 'rails'—not private platforms—to ensure inclusion, integrity, and responsible private innovation.

The BIS advocates for digital public infrastructure (DPI) — including digital ID, fast payments, and data-sharing frameworks — to serve as foundational, interoperable, and inclusive 'public rails' that enable responsible private-sector innovation on top. It emphasizes that such DPI must be publicly governed, designed with strong consumer protection and inclusive features, and aligned with financial health outcomes; private platforms alone are insufficient and risk fragmentation, exclusion, or instability without these shared, regulated rails. The BIS cautions against both unregulated public permissionless systems (which suffer from congestion, privacy issues, and inadequate safeguards) and closed private permissioned networks (which risk creating walled gardens), instead favoring interoperable, permissioned public rails settled in central bank reserves.
