Papua New Guinea’s Budget Reset: Can Smarter Spending Controls Unlock Public Investment Growth?

Papua New Guinea’s monthly cash-rationing system is delaying capital projects, increasing payment risks and weakening budget credibility, prompting the IMF to recommend a shift toward quarterly, commitment-based expenditure controls. The reforms could reduce arrears, improve public investment delivery and give government agencies, development partners and private suppliers greater certainty over contracts and payments.

Papua New Guinea's difficulty in turning approved budgets into actual projects and public services is becoming a wider economic and development concern. A May 2026 assessment by the International Monetary Fund's Fiscal Affairs Department (IMF FAD), supported by the Global Public Finance Partnership (GPFP), finds that the country's expenditure-warranting system helps prevent spending beyond available cash, but also creates uncertainty, delays capital projects and contributes to unpaid government obligations. The central challenge is to preserve fiscal discipline while giving ministries, contractors and development partners greater certainty about when approved money will actually become available.

When an Approved Budget Does Not Mean Money Is Available

Papua New Guinea currently relies heavily on monthly expenditure warrants based on available cash. The problem begins when expected government resources do not match spending approved in the national budget. Revenue can be volatile, external financing uncertain and dividends from state-owned enterprises lower than projected. Expenditure pressures can also emerge during the year, including political demands for additional projects.

Treasury consequently has to ration available cash. This creates a gap between what Parliament approves and what government agencies can actually spend.

The Department of Education illustrates the problem. Warrants released represented only 63% of its development budget in 2024 and 59% in 2025. Yet the department spent more than 90% of the development expenditure that was actually warranted in both years. This suggests that low capital spending can reflect unpredictable financing releases as well as weaknesses in implementation capacity.

Capital projects suffer in particular because infrastructure cannot be managed efficiently month by month. Contractors need predictable schedules for materials, labour and subcontractors, while government agencies need to know when resources will be available. Late warrants can delay procurement, postpone projects and push financial obligations into the following budget year.

Payment Delays Are Becoming an Economic Cost

Cash rationing protects the government from exhausting its available resources, but it can transfer financial pressure to businesses.

When government invoices remain unpaid, suppliers must finance the delay themselves. Companies may respond by increasing prices to cover payment risks or demanding payment before supplying goods and services. The report says authorities have observed suppliers increasingly seeking advance payment.

That can make public procurement more expensive and discourage businesses from competing for government contracts. Smaller domestic companies may be particularly exposed because they generally have less working capital to absorb long payment periods.

For policymakers, this means expenditure management has consequences beyond government accounting. Persistent payment uncertainty can weaken private-sector confidence, reduce competition for public contracts and increase the ultimate cost of infrastructure and public services.

Another concern is that government commitments are not systematically registered in the Integrated Financial Management System (IFMS) when contracts are created. Controls therefore often become effective relatively late, when invoices are approaching payment. By that stage, the government may already have incurred obligations without having sufficient cash available.

Although expenditure exceeding K1 million requires an Authority to Pre-Commit certification, the IMF finds that this mechanism is not currently effective enough in controlling major longer-term commitments.

From Monthly Cash Rationing to Quarterly Planning

The IMF proposes a fundamental change: Papua New Guinea should gradually move from monthly warrants based on immediate cash availability to quarterly warrants based on planned commitments.

Instead of controlling expenditure mainly when an invoice needs to be paid, the government would determine whether it can afford an obligation before a contract or major purchase order is signed.

The IFMS would become central to this system. Significant commitments would be registered in advance and checked against both approved budget appropriations and available warrant authority. Approved commitments could then receive a unique system-generated authorization code.

Suppliers would know that qualifying government contracts should contain this authorization. This could protect businesses from entering agreements that have not been properly approved while helping government identify future liabilities before they become payment problems.

But technology alone cannot solve the problem. Papua New Guinea needs a more credible annual budget and better cash-flow forecasts. Ministries implementing multi-year projects must estimate future payments more accurately, while projected dividends from state-owned enterprises should reflect realistic expectations.

New spending priorities introduced during the year also need identified financing. Otherwise, politically attractive new projects can squeeze resources already allocated to existing programmes, causing delays, arrears or abandoned investments.

What Policymakers, Development Partners and Businesses Should Watch

Institutional responsibility will be critical. The IMF recommends keeping warrant authority with the Department of Treasury while cash rationing continues because warrants effectively determine which government priorities receive scarce resources. The Department of Finance should continue managing banking, payments, accounting and reporting.

For development partners, stronger commitment control could improve the reliability of government counterpart funding and reduce delays in infrastructure and development programmes. International financial institutions and donors could support capacity building in cash forecasting, public investment management, financial systems and procurement.

Private companies could benefit from more predictable contracts and payments. Greater certainty could attract additional suppliers, strengthen competition and potentially reduce the risk premiums businesses include in government bids. However, poorly designed reforms could create additional bureaucracy, particularly for smaller suppliers, making training and clear communication essential.

The proposed transition begins with clarifying institutional responsibilities in 2026. From 2027, the government should strengthen commitment registration, introduce authorization mechanisms, improve medium-term cash forecasting and make state-owned enterprise dividend projections more reliable. The report envisages movement toward quarterly commitment warrants by late 2027, alongside efforts to reduce off-budget activities.

The larger policy message is simple: fiscal discipline should mean more than stopping payments when government runs short of cash. Papua New Guinea needs to prevent unaffordable commitments from being created in the first place. If implemented effectively, the reforms could reduce arrears, improve capital-project delivery, lower procurement risks and give government agencies, businesses and development partners greater confidence that approved budgets can actually be delivered.
