From Public-Private Partnerships to Sovereign-Private Partnerships: Why Infrastructure Should Become Statecraft

Introduction

By Mark Kennedy

Infrastructure is increasingly a domain of strategic competition. Ports, logistics corridors, digital networks, AI infrastructure, and energy systems now shape not only economic performance, but also resilience, sovereignty, and geopolitical alignment.

As strategic competition intensifies, governments and private actors alike are reassessing how capital is deployed, how infrastructure ecosystems are governed, and how trusted systems are built and sustained across allied and partner networks.

At the Wahba Initiative for Strategic Competition (WISC), we increasingly view these issues through the lens of systems competition—the ability of nations and coalitions to align and scale capital, technology, infrastructure, institutions, and operational capacity. This systems-oriented perspective builds on themes explored in my book, Shapeholders, which examines how leaders shape outcomes by influencing the broader systems in which institutions, markets, and societies operate.

In this context, Mark Choi’s concept of “Sovereign–Private Partnerships” (SPPs), below, offers a useful framework for understanding how infrastructure finance is evolving beyond traditional public-private models toward structures that integrate alignment with trusted supply chains, secure logistic networks, global dispersion of an allied AI stack, and other national strategic goals.

The Limits of Public-Private Partnerships

For decades, public–private partnerships (PPPs) reigned as the dominant framework for building and financing infrastructure. Born in an era of fiscal constraint and market efficiency, they were designed to stretch public budgets and transfer construction risk—not to secure chokepoints, achieve strategic objectives, or project national strategy. The formula worked up to a point. PPPs were effective for financing toll roads, waste management facilities, municipal water projects, and similar infrastructure—important, but strictly utilitarian. PPPs operate at the level of procurement, building and compliance—not at the level of strategic purpose.

In an age defined by strategic rivalry and the re-ordering of global power, seeking efficiency alone cannot safeguard sovereignty.

From Efficiency to Alignment

Infrastructure today is no longer neutral. It has become a strategic domain—where ports, grids, and data networks embody questions of power, trust, and legitimacy. The same fiber cables that connect markets also delineate spheres of influence. The same LNG terminals that fuel growth can also determine geopolitical leverage.

Under such conditions, the utilitarian logic of PPPs cannot meet the demands of statecraft in the twenty-first century. What today’s moment requires is a new framework: the sovereign-private partnership (SPP).

Defining the SPP

An SPP is a collaborative investment structure in which private capital is aligned with sovereign strategy from inception—co-designed, co-financed, and co-governed to advance national and allied resilience alongside long-term profitability. An SPP serves a dual function: achieving strategic sovereign objectives and delivering financial returns.

The SPP represents a reorientation of capital toward purpose—a model in which private execution is guided from the outset by sovereign intent, strategic resolve, and geopolitical alignment. It seeks to align efficiency with legitimacy and profit with resilience. In doing so, it reconnects capital to strategic purpose, resilience, and long-term societal outcomes—helping build national capability, strengthen trusted economic systems, and support durable prosperity and growth.

PPP vs. SPP

Capital as a Strategic Instrument

This synthesis is not without precedent. In the aftermath of World War II, the Marshall Plan mobilized sovereign-aligned capital to serve strategic ends. Through a blend of U.S. government funding and private execution, the plan rebuilt war-torn European infrastructure, secured alliances, and anchored the Western world under a dollar-based, U.S.-led financial architecture. The Bretton Woods institutions such as the IMF and World Bank extended this alignment—reinforcing convertibility, stabilizing currencies, and channeling capital flows in support of a rules-based international system.

If the Marshall Plan and Bretton Woods represented the high-water mark of U.S.-led sovereign capital deployment, similar alignments of strategic purpose and capital persist today, offering modern global demonstrations of what SPPs can achieve.

One example is Temasek, Singapore’s state-owned investment company. Founded in 1974 to steward national assets, Temasek has evolved into one of the world’s most respected investment institutions. It helped catalyze Singapore’s transformation from a resource-poor trading outpost into a global financial and innovation hub—demonstrating that sovereign objectives and long-term value can be aligned and mutually reinforced.

Though Singapore’s context is unique, Temasek illustrates a core SPP principle: sovereign aligned capital can be deployed through market mechanisms to advance national priorities, economic security, and broad-based opportunity for a nation’s citizens. It offers a real-world example of how statecraft and investment discipline can operate in concert and deliver long-term value in a competitive, global environment.

In each of these cases, capital functioned as a strategic instrument—a way to embed sovereign objectives and societal uplift into economic activity. The late twentieth century, shaped by the ascendancy of market liberalism and globalization, decoupled capital from national purpose. Efficiency replaced meaning as the greatest good. Yet in the current era of strategic competition, that detachment has become a vulnerability. The bifurcation of technological systems, the weaponization of supply chains, and the erosion of global trust all point to a need for reintegration, particularly the return of national and allied purpose to the deployment of capital.

SPPs can extend this lineage—using twenty-first century financial instruments to fulfill the same sovereign imperative that shaped postwar reconstruction, nation building, and shared prosperity. The next task is embedding sovereign intent into investment design, incentives, and governance.

Implementing the SPP Framework

SPPs must function not merely as project finance vehicles, but as strategic instruments of alignment in which private capital advances national and allied resilience. The central insight is that modern competition unfolds not only through defense or trade policy, but also through the connective tissue of infrastructure: energy corridors, undersea cables, logistics hubs, and digital networks.

Embedding sovereign intent from the outset requires deliberate coordination across finance, policy, and industry. Instruments such as first-loss capital, political-risk insurance, and long-term offtake agreements—deployed through entities such as the U.S. International Development Finance Corporation (DFC), U.S. Department of Defense’s Office of Strategic Capital, allied development banks, and sovereign wealth vehicles—can anchor that intent in structure. These tools can convert strategic purpose into investable form.

Such frameworks allow governments to project influence through credible investment partnerships. For private investors, these structures open mission-linked pipelines and unique opportunities supported by protections such as offtake agreements, price floors, credit enhancements, and public risk-sharing mechanisms that de-risk strategic projects (otherwise not possible in a purely market environment). Over time, this could create a network of trusted infrastructure ecosystems spanning the energy transition, digital connectivity, and critical mineral supply chains across allied partners. Capital becomes an instrument of trust-building, reinforcing the strategic architecture on which open societies depend.

Strategic Stewardship: Building What Endures

The ultimate test of infrastructure capital is not merely the efficiency of its projects, but the endurance of the systems it builds. Infrastructure conceived only for return can become brittle; infrastructure animated by purpose endures.

Markets alone cannot safeguard the commons, nor can states act effectively without private ingenuity. What binds them is stewardship: a recognition that capital, when directed with foresight and discipline, can achieve not just financial returns but the advancement and continued resilience of open civilization.

The shift from PPPs to SPPs therefore marks more than a financial innovation; it signals a restoration of intent—the fusion of private capability with sovereign purpose to secure resilience, legitimacy, and strength in an uncertain world.

The next generation of partnerships will not be measured by efficiency alone, but by alignment among what is built, whom it serves, and what it secures.
