Saudi Fiscal Sustainability Under Stress
Saudi Arabia’s fiscal position presents a paradox of strength and vulnerability. On one hand, the Kingdom possesses assets that most nations would envy: approximately $400 billion in central bank reserves, a sovereign wealth fund approaching $1 trillion, the world’s lowest-cost oil production, strong credit ratings, and a debt-to-GDP ratio of approximately 26%. On the other hand, Saudi Arabia faces a rising fiscal breakeven oil price (approximately $90-96 per barrel), mounting expenditure commitments from giga-projects and social programmes, and an oil market facing structural uncertainty from the global energy transition.
The question is not whether Saudi Arabia faces an imminent fiscal crisis — it manifestly does not — but whether its current spending trajectory is sustainable over the medium to long term, and what adjustments may be necessary if oil prices fail to cooperate.
The Revenue Picture
Saudi government revenue remains dominated by oil, though non-oil revenue has grown substantially:
| Revenue Source | 2016 | 2020 | 2025 (est.) | Share of Total |
|---|---|---|---|---|
| Oil revenue | SAR 334B | SAR 413B | SAR 620B | ~62% |
| Non-oil revenue | SAR 186B | SAR 265B | SAR 380B | ~38% |
| Total revenue | SAR 520B | SAR 678B | SAR 1,000B | 100% |
Non-oil revenue growth has been driven primarily by VAT (introduced at 5% in 2018, raised to 15% in 2020), excise duties on tobacco and sugary drinks, government service fees, and returns on government investments. The VAT increase alone added approximately SAR 100 billion in annual revenue — a significant achievement that demonstrated the state’s capacity to implement new tax instruments.
However, non-oil revenue remains insufficient to cover government expenditure without oil revenue. Even at SAR 380 billion, non-oil revenue covers less than 35% of total government spending.
The Expenditure Trajectory
Government spending has grown substantially under Vision 2030, driven by several categories:
Current expenditure — public sector wages, subsidies, healthcare, education, defence — constitutes the majority of the budget and is relatively inflexible. Public sector wages alone account for approximately 45% of current spending. While subsidy reform has reduced energy and water subsidy costs, the government has simultaneously increased social support programmes (Citizen’s Account, housing subsidies) that partly offset these savings.
Capital expenditure — infrastructure, giga-projects, economic development — has grown sharply. Saudi Arabia’s capital spending as a share of GDP is among the highest in the world, reflecting the intensity of Vision 2030 investment.
Defence spending — historically 5-7% of GDP — remains a significant fiscal commitment, driven by regional security dynamics including the Yemen conflict aftermath and broader Gulf security concerns.
Social spending — including the Citizen’s Account programme, which provides direct cash transfers to offset VAT and subsidy reform impacts — has created new expenditure commitments that are politically difficult to reduce.
The Breakeven Oil Price
The fiscal breakeven oil price has become the single most important metric for assessing Saudi fiscal sustainability. This price — the oil price needed to balance the government budget — has risen from approximately $70 per barrel in 2019 to an estimated $90-96 per barrel in 2025-2026.
The rising breakeven reflects the combination of increased spending (giga-projects, social programmes, capital investment) and OPEC+ production cuts that reduce oil revenue volume. When Saudi Arabia cuts production to support prices, it reduces volume-based revenue even as it supports price-based revenue — a trade-off that raises the breakeven price.
At prevailing oil prices of $70-85 per barrel through much of 2024-2025, Saudi Arabia has been operating below its fiscal breakeven, resulting in budget deficits.
Deficit and Debt Trajectory
Saudi Arabia recorded budget deficits in both 2024 and 2025, with the 2025 deficit estimated at approximately 3-4% of GDP. These deficits have been funded through a combination of:
Debt issuance. Saudi Arabia has actively issued sovereign bonds in both domestic and international markets. Total government debt has risen from approximately 1.6% of GDP in 2014 to approximately 26% in 2025. While this level remains low by international standards, the trajectory is upward.
Reserve drawdowns. Central bank foreign reserves have declined modestly from peak levels, though they remain substantial at approximately $400 billion.
PIF transactions. Asset transfers between PIF and the government, including Aramco dividend flows, create fiscal flexibility that is not fully captured in conventional budget analysis.
The debt trajectory, while currently manageable, is the critical variable for long-term fiscal sustainability. Each year of deficit spending adds to the debt stock, increasing interest costs and reducing fiscal flexibility.
Stress Test Scenarios
A rigorous fiscal sustainability assessment requires stress-testing against different oil price scenarios:
Scenario 1: Oil at $85-95 (Near breakeven) Budget approximately balanced. Debt stabilises. Vision 2030 spending proceeds as planned. This is the baseline assumption underlying current fiscal plans.
Scenario 2: Oil at $70-80 (Moderate stress) Annual deficits of 3-5% of GDP. Debt rises to 35-40% of GDP by 2030. Some giga-project spending deferred. Non-critical capital expenditure reduced. Manageable with existing buffers but requires spending discipline.
Scenario 3: Oil at $55-65 (Significant stress) Annual deficits of 6-8% of GDP. Debt rises rapidly toward 50% of GDP. Material giga-project deferrals required. Social spending under pressure. Credit rating downgrades possible. Requires fundamental reprioritisation of Vision 2030 investment.
Scenario 4: Oil at $40-50 (Severe stress) Unsustainable deficits without drastic spending cuts. Giga-projects halted or dramatically scaled back. Social welfare programmes under threat. Reserve depletion accelerates. Structural fiscal adjustment required — potentially including personal income tax introduction, further VAT increase, or deep spending cuts.
| Scenario | Oil Price | Annual Deficit | Debt/GDP 2030 | Programme Impact |
|---|---|---|---|---|
| Baseline | $85-95 | ~Balanced | ~28% | Full programme |
| Moderate stress | $70-80 | 3-5% GDP | ~38% | Selective deferrals |
| Significant stress | $55-65 | 6-8% GDP | ~50% | Major reprioritisation |
| Severe stress | $40-50 | 10%+ GDP | ~65%+ | Programme at risk |
Fiscal Buffers and Their Limits
Saudi Arabia possesses substantial fiscal buffers that provide resilience against oil price shocks:
Central bank reserves (~$400B) could cover approximately 3-4 years of budget deficits at the moderate stress scenario level before reaching levels that would concern international markets.
PIF assets (~$941B) represent massive wealth, but a significant portion is illiquid (Aramco stake, giga-project investments, private equity) and cannot be readily monetised to cover budget deficits.
Debt capacity remains substantial. Saudi Arabia’s credit ratings (Fitch A+, Moody’s A1) support continued access to international capital markets at competitive rates. The Kingdom could theoretically sustain debt-to-GDP ratios of 40-50% before facing market pushback, providing a buffer of approximately 15-25 percentage points above current levels.
Non-oil revenue elasticity provides some automatic stabilisation — VAT revenue, for example, is less oil-dependent than headline revenue figures suggest, providing a floor under government income.
However, these buffers are finite and exhaustible. Using reserves to fund deficits is a drawdown of national wealth. Issuing debt creates future obligations. And PIF assets, while large, serve dual purposes (financial returns and development investment) that limit their availability as fiscal backstops.
The Non-Oil Revenue Imperative
Long-term fiscal sustainability ultimately depends on growing non-oil revenue to a level that covers a larger share of government expenditure. Several levers are available:
VAT adjustment. The current 15% rate could theoretically be increased further, though this would be politically sensitive and potentially contractionary. Regional comparison: the UAE introduced VAT at 5% and has not yet increased it.
Personal income tax. The introduction of personal income tax on Saudi nationals is the single most consequential potential fiscal reform and the most politically sensitive. No Gulf state has introduced personal income tax, and doing so would represent a fundamental shift in the social contract. However, as a long-term fiscal sustainability measure, it may become necessary.
Corporate tax reform. The current 20% corporate income tax rate applies to foreign-owned businesses, while Saudi-owned businesses pay Zakat at 2.5%. Harmonising these rates — potentially at a lower combined rate — could increase corporate tax revenue while reducing the distortion between domestic and foreign business treatment.
Government asset monetisation. Privatisation, IPOs of government entities, and land sales can generate one-time revenue while also improving economic efficiency. The Aramco IPO demonstrated this approach at scale.
Fee and service revenue. Continued expansion of government service fees, visa charges, and user fees can contribute incrementally to non-oil revenue.
Expenditure Adjustment Options
If revenue proves insufficient, expenditure adjustment becomes necessary. The options range from politically easy to politically painful:
Giga-project phasing — extending timelines and reducing near-term spending on NEOM, Qiddiya, and other mega-developments. This is the most likely first response to fiscal pressure and has arguably already begun.
Capital expenditure deferral — delaying non-essential infrastructure investment. Effective for short-term fiscal relief but reduces long-term economic capacity.
Defence spending reform — reducing military expenditure is theoretically possible but constrained by regional security dynamics and political considerations.
Public sector wage restraint — limiting wage growth for government employees. This has already been implemented to some degree but faces resistance from a workforce that constitutes a key political constituency.
Social programme reduction — cutting Citizen’s Account transfers or other social support. This is the most politically costly option and is likely a last resort.
The IMF Perspective
IMF Article IV consultations with Saudi Arabia have consistently flagged fiscal sustainability as a key risk. The Fund’s recommendations typically include:
- Continued non-oil revenue diversification
- Expenditure restraint, particularly on current spending
- A medium-term fiscal framework that targets budget balance at conservative oil price assumptions
- Greater transparency in fiscal reporting, including off-budget spending through PIF
These recommendations are sound in principle but politically challenging to implement fully. The tension between IMF-style fiscal discipline and the political imperative to deliver Vision 2030’s transformative investments is inherent and cannot be fully resolved — only managed.
Conclusion
Saudi Arabia’s fiscal position is strong by most conventional metrics but under emerging pressure from rising expenditure commitments, elevated breakeven oil prices, and structural uncertainty about future oil demand. The Kingdom is not facing a fiscal crisis, and its buffers provide years of resilience against adverse scenarios. But the current spending trajectory is sustainable only if oil prices remain near or above $85-90 per barrel — a condition that is plausible but not certain.
The prudent course — which Saudi fiscal policy appears to be partially but incompletely following — involves accelerating non-oil revenue growth, prioritising the highest-return Vision 2030 investments, accepting slower timelines for lower-priority giga-projects, and maintaining the debt discipline that preserves the Kingdom’s strong market access.
The fiscal test of Vision 2030 is not whether the programme can be funded at current oil prices — it can — but whether it can survive and adapt if oil prices fall materially and stay low. The answer to that question will determine whether Vision 2030’s investments become self-sustaining assets or stranded expenditures.
