Saudi Fiscal Strain: What Is War-Driven and What Is Structural

Saudi Arabia’s 2026 budget deficit is now forecast at 4.9% of GDP. That is smaller than the 5.8% gap recorded in 2025, yet larger than the government’s own 2026 budget allowed for. Both statements are true, and that is why a simple “deficit widening” headline misreads the kingdom’s fiscal strain.

The numbers come from the Ministry of Finance’s 2027 pre-budget statement, released on 30 September 2026. On Monday, 5 October, Fitch Ratings commented that the war between the US and Iran is putting pressure on public finances, as Riyadh plans to spend more and run bigger gaps between revenue and outlays.

Oil investors need to know whether that pressure is temporary or built in. A war-driven spike should fade once the conflict ends. A deficit rooted in oil dependence and debt-funded megaprojects will not.

Here is how to tell which parts of this deficit come from the war and which are structural. It also covers what each means for oil markets and your energy exposure.

Why the 2026 deficit is both better and worse than it looks

Start with the comparison most readers will make. Against 2025, the 2026 deficit ratio has improved, falling from 5.8% to 4.9% of GDP.

Now set it against the plan. The original 2026 budget targeted a shortfall of SAR 165 billion (about US$44 billion). Reuters, via Zawya, reports that the pre-budget statement revises that figure to SAR 245 billion, roughly 48% above target.

One outlet differs. AGBI’s reporting implies a 2026 estimate of about SAR 164 billion, which would sit below the original target and contradicts the overshoot the ministry described. This analysis uses the Reuters figure.

The cause is oil. The ministry projects a 21.8% contraction in oil activities in 2026 as regional conflict hits output, which pulls real GDP into decline. The 12.8% growth projected for 2027 is mostly a rebound from that low base, so it should not be read as a new growth trend.

The 2027 deficit of about SAR 191 billion (roughly US$50.9 billion) eases the pressure but does not end it. Riyadh has said plainly how the gap will be filled:

The Ministry of Finance pre-budget statement puts the 2027 deficit at SAR 191 billion, or 3.6% of GDP, with spending of SAR 1,392 billion against revenue of SAR 1,202 billion and borrowing under a medium-term debt framework.

The 2027 deficit “will be funded through borrowing in accordance with a medium-term debt strategy framework,” according to the pre-budget statement.

The takeaway for you is that a falling deficit ratio does not mean the plan is on track. The government is still missing its own targets and relying on debt, and details of the borrowing plan are due by the end of 2026.

What is driving the strain: war spending, lost barrels and a high breakeven

Oil prices have been firm, so why are deficits wider than planned? Four forces explain it.

1. Front-loaded war spending. According to Fitch, much of the jump in spending in Q1 2026 was precautionary spending brought forward.
2. Lost barrels. A 3 June 2026 report put Saudi output at about 7.25 million barrels per day, against an OPEC+ quota of 10.291 million. It blamed Strait of Hormuz constraints and estimated a revenue gap of US$80-101 million a day, a figure that has not been independently verified.
3. A partial price offset. Brent near US$91 in late May softened the volume loss but did not cancel it.
4. Vision 2030 and Public Investment Fund (PIF) commitments. The kingdom’s megaproject programme keeps spending high regardless of oil prices.

The best way to measure this pressure is the fiscal breakeven: the oil price at which government revenue covers spending. The difficulty is that each forecaster defines it differently. The biggest difference is whether spending by the PIF, the sovereign wealth fund, is included.

These are analyst estimates, not official figures. Even so, the spread matters. At US$91, Saudi finances look close to balanced on the narrowest measure and more than US$15 short on the broadest. When you see a claim about Saudi fiscal health, check which definition it uses.

Cyclical pressures that should fade

War spending and front-loading should reverse. Fitch said in July that it expects spending to fall in 2027 as war pressures ease and capital expenditure declines. The 2026 price windfall is also temporary.

Structural pressures that will not

Vision 2030 and PIF commitments keep the effective breakeven high. That leaves the budget dependent on high oil prices and on borrowing to fund megaprojects, and neither problem goes away when the war does.

The kingdom’s renewables pipeline is one example of the megaproject spending that continues regardless of oil prices, with large announced capacity but a much smaller operational base so far.

How worried should credit markets be? Fitch’s A+ view in context

Credit markets have good reason to stay calm. Fitch rates Saudi Arabia A+ with a Stable Outlook, citing strong fiscal buffers, low government debt and large financial assets. Those strengths are weighed against oil dependence and growing deficits.

Sovereign credit rating frameworks weigh buffers such as low debt and large reserves against geopolitical risk, which is why an A+ rating can coexist with a deficit that overshoots its own budget target.

One source dates the latest affirmation to 10 July 2026. Fitch’s comments on the pre-budget statement are dated 5 October.

In Fitch’s reading, the war with Iran is straining the public finances, and Riyadh is budgeting for larger outlays and bigger gaps between income and spending.

The more telling detail is what changed between July and October. According to Asharq Al-Awsat, Fitch said in July that the 2026 deficit would narrow because higher prices would offset lower volumes. It expected about 4.7% of GDP in 2027 and further narrowing in 2028. Instead, the 2026 shortfall came in above target, and that gap between expectation and outcome is the real signal.

What supports the rating:

• Low government debt and large reserves
• A strong net external asset position
• No reported pressure on the riyal’s peg to the US dollar

What could weaken it:

• Breakevens staying above sustainable oil prices, which would steadily raise debt and interest costs
• Spending that fails to adjust after the war
• An IMF scenario, not independently verified, in which a Hormuz reopening lowers prices and widens deficits again

The Saudi government has cut back before. The 2015-16 oil downturn and the 2020 austerity programme both brought spending cuts, subsidy reform and project reprioritisation. No recent Moody’s, S&P or JPMorgan commentary was found that links the current strain to the war.

Read the A+ rating as a measure of how well the kingdom can absorb shocks today. It is not a guarantee about the medium term if prices fall and spending stays high.

What it means for oil markets and energy investors

Saudi Arabia is producing fewer barrels and needs a high price to balance its books. For now, that combination helps hold prices up. Goldman Sachs, Wood Mackenzie and Bloomberg Economics have described this as a “double squeeze” of low volumes and high breakevens, though these views have not been independently verified.

The risk comes if peace removes the war premium faster than output recovers. Riyadh would then face lower prices before its revenue from higher volumes catches up.

Scenario: the war premium fades

Wood Mackenzie’s “Quick Peace” case, which has not been independently verified, has Brent at US$80, falling to US$65 by 2027. On a PIF-inclusive breakeven of US$108-113, the gap would exceed US$40 a barrel.

In that case, the likely responses are more borrowing, slower capital spending and a rethink of some Vision 2030 projects. Past downturns suggest the direction is clear, though current consolidation looks more targeted than broad austerity. OPEC+ may also manage supply more tightly once the Hormuz constraints ease.

OPEC+ quota decisions will determine how quickly Saudi output climbs back toward its 10.291 million barrel target once Hormuz constraints ease, and competing supply-demand forecasts show how wide the range of outcomes remains.

For energy investors, this cuts both ways. Fiscal pressure supports prices today, but it also raises the chance of project delays, more volatile Saudi bond issuance and more cautious long-term commitments from international partners. Watch these signposts:

1. The borrowing plan, due by the end of 2026
2. The Hormuz reopening and how quickly output recovers
3. OPEC+ quota decisions
4. Any phasing or delay of Vision 2030 projects

Past performance does not guarantee future results. Financial projections are subject to market conditions and various risk factors, and the scenarios above are speculative.

Reading the next Saudi budget signal: what is settled and what is not

The overall picture holds together. The 2026 deficit is smaller than in 2025 but larger than planned. The strain is partly caused by the war and partly structural, and credit buffers are strong but finite.

Some things are settled: the A+ rating, the reliance on borrowing in 2027 and the pre-budget figures. Others remain open, including the details of the borrowing plan, the timeline for reopening Hormuz and where prices settle after the war.

Before changing your view on Saudi exposure, track three releases: the end-2026 borrowing plan, monthly output data showing whether production is returning to quota, and the final 2027 budget’s capital spending figures. All figures reflect public reporting as of early October 2026.
