From Aid Reliance to Resilient Financing

Debates on development finance have shifted from short-term aid disruptions to more fundamental questions about the future of assistance itself. What initially appeared as isolated shocks, such as the suspension of USAID funding, are increasingly understood as symptoms of a broader structural transition. While we may not yet be fully in a post-aid world, the underlying dynamics of such a shift are already becoming evident.

Aid Has Peaked, What This Means for Water

There is growing consensus that global aid has reached a high-water mark. Pandemic-era expansions have given way to fiscal tightening, geopolitical reprioritisation, and mounting domestic political constraints in donor countries. In this emerging “post-aid” narrative, development assistance is becoming more volatile, more politically conditioned, and less aligned with long-term sector strategies.

The closure of USAID-funded programmes was a critical moment for the water sector, exposing vulnerabilities created by reliance on a narrow set of donors. Yet this was not an isolated event. For some time, the development finance landscape has been shifting. Foreign direct investment and remittance flows now far exceed official development assistance in many countries, underscoring that aid is no longer the dominant source of external finance. Instead, it has become a subset of a much wider pool of capital that increasingly shapes development trajectories.

For water and sanitation, historically dependent on predictable, concessional funding for capital-intensive infrastructure and institutional reform, the implications are profound. Reduced grant and concessional finance is already constraining infrastructure investment, sanitation expansion, and institutional strengthening. Many countries now face widening gaps between what is required to meet universal access targets and what public budgets can support, weakening long-term planning and increasing the risk that critical projects are delayed, scaled back, or abandoned.

In last year’s blog following the ceasing of USAID funding, I argued that dependence on a single major donor created systemic vulnerability and highlighted the need for alternative financing pathways. That concern now appears structural rather than situational. The contraction of aid is not confined to one agency or one country; it reflects a broader realignment in how development is financed. The central question is therefore no longer how to manage the loss of a single donor, but how the water sector can adjust to declining commitments from traditional aid providers and position itself within a broader and more diversified development finance architecture.

A Changing Logic of Development Finance

The shift toward a post-aid world is not only about declining volumes of assistance, but also about changing motivations. Where aid once reflected long-term development commitments shaped by alliances and international solidarity, it is now increasingly influenced by domestic political pressures, strategic competition, and donor self-interest. Even if we are not yet beyond aid, these dynamics are already reshaping where, how, and why development finance is deployed.

At the same time, aid’s relative importance within the wider financing ecosystem has diminished. Private capital and cross-border financial flows now dominate many national financing landscapes. For the water sector, this means aid can no longer be treated as the default or central funding source, but must be situated within a broader mix of public, private, and market-based resources.

The consequences are significant. Infrastructure lifecycles extend over decades, but financing commitments increasingly do not. As funding becomes more fragmented and less predictable, water investments are exposed to political cycles, shifting priorities, and market volatility. Projects face greater risks of discontinuity, and institutions struggle to retain capacity when funding streams are interrupted. As highlighted in last year’s blog, the challenge is not only the loss of resources but the erosion of continuity.

Repositioning Water Finance in a Post-Aid Landscape

At the same time, declining aid budgets and rising demand for water and sanitation require more resilient financing models. Historically, the sector has relied heavily on concessional funding for capital-intensive investments. The emerging landscape instead calls for approaches that are more locally anchored and capable of mobilising a broader mix of resources, including commercial finance, institutional investors, and diaspora capital alongside public funds. Within this context, the financing approaches outlined in last year’s blog are no longer simply innovative; they are increasingly necessary.

Anchoring water investment within domestic financial systems can reduce exposure to external funding shocks, while blended finance and impact investment can crowd in private capital without sacrificing social and environmental objectives. As water security is increasingly recognised as integral to climate resilience, instruments such as green bonds and sustainability-linked finance are gaining relevance, with multilateral development banks likely to play an even more central role as bilateral aid contracts. Together, these shifts reflect a redefinition of aid from a primary funding source to a catalytic tool for policy reform, risk mitigation, institutional strengthening, and domestic resource mobilisation. If the sector is entering the early stages of a post-aid era, the challenge is not to replace aid, but to embed it strategically within a diversified financing ecosystem capable of sustaining services over the long term.

At the same time, expectations of large-scale private capital must be tempered by experience. Under the World Bank’s “Millions to Trillions” agenda and the so-called “Wall Street Consensus,” development institutions sought to mobilise unprecedented volumes of private investment into infrastructure and social sectors. In practice, this has not delivered the scale anticipated, particularly in water, where weak revenue models, regulatory uncertainty, currency risk, and political constraints continue to limit investor appetite. This does not imply that such approaches should be abandoned, but it does require a more critical assessment of why results have fallen short, whether due to insufficient effort, inappropriate financial structures, or the presence of more attractive opportunities for private capital elsewhere. Without confronting these constraints, ambitions for private financing in water will continue to outpace market realities. Taken together, these considerations point toward a financing ecosystem that is more diversified and resilient, but also grounded in an honest appraisal of risk, incentives, and sector fundamentals.

Financing Water Beyond Aid

The idea of a “post-aid world” raises a fundamental question: what comes after traditional development assistance? Even if we are not fully there, the forces reshaping development finance are already evident. The closure of USAID programmes was a significant inflection point, but it forms part of a longer-term transformation in which aid is only one component of a much broader financing landscape.

For the water sector, the response lies in building financing systems that are diversified, locally grounded, and resilient to donor withdrawal. As argued in last year’s blog following the ceasing of USAID funding, innovation in water finance is no longer optional. That message is now even more pressing. The future of water and sanitation will depend not on restoring past aid flows, but on how effectively the sector can harness a wider range of financial resources to deliver sustainable services in a fundamentally changing development finance environment.
