Saudi Arabia is building businesses outside oil. The harder transition is building businesses whose financing, customers and resilience can withstand a change in oil income. The Middle East’s current crisis is testing all three at once.

The answer, before the argument

Those numbers answer the observable fiscal question. They do not establish that 63.6% of the non-oil economy is caused by oil. A credible economy-wide causal percentage would require enterprise-level customer and financing data, a consolidated public-sector account, and a model of what would happen when oil-linked support changes. The reviewed public evidence does not provide that decomposition.

The defensible finding is more useful than a false precision: oil remains a major source of current public funding, an income-producing asset behind PIF, and a support to domestic demand. At the same time, tourism receipts, private employment and commercially maturing investments show that the new economy has substantive activity and earnings of its own. Its independence varies by business model.

Five findings organize this study:

1. The tax base is broader; the spending base remains much larger. Non-oil revenue reached SAR 505.3 billion in 2025, up from approximately SAR 166 billion in 2015. The improvement is substantial. It still financed only a little over one-third of central-government spending. MoF [1], long-term comparison [3].
2. An oil shock can strengthen one set of accounts while weakening another. In Q2 2026, government oil receipts rose 22.0% year on year, while real oil activity fell 24.8% and non-oil activity grew 0.9%. Price, volume, payment timing and real output are separate measures. Fiscal receipts [2], GDP [4].
3. PIF changes where oil-linked wealth is invested and received. Transfers have placed 16% of Aramco’s issued shares with PIF and its companies. Aramco also identifies HUMAIN among its AI investments. These are channels beyond the central budget; they do not mean that every supported business is permanently dependent on oil. Aramco ownership history [5], PIF transfer announcement [6], Aramco AI strategy [7].
4. The geography of resilience also creates exposure. Red Sea ports handled a much larger share of Saudi trade during March–June 2026 than in January–February. That provides an alternative to Gulf routes, while leaving Saudi commerce exposed to regional security, insurance and transport constraints. MoF trade-routing evidence [3].
5. The next test is commercial cash generation. PIF’s emphasis on returns and capital efficiency, Saudi AI partnerships, tourism growth and rising financing needs converge on one question: which assets can earn enough from customers to reduce their need for continuing public support?

A dashboard of measures that should not be confused

1. The region is testing the new economy’s business model

The economic significance extends beyond the immediate damage. An economy built around exporting a commodity can sometimes offset lower delivered quantities with a higher price. An economy seeking visitors, conventions, global employers and internationally connected digital businesses needs customers to believe they can arrive, operate and leave predictably.

Saudi Arabia’s transformation therefore faces two tests during the same regional crisis. Can the existing energy system keep generating revenue? Can the newer businesses keep attracting demand and investment? Passing the first does not guarantee passing the second.

The central proposition of this report is that a country can diversify its sector mix faster than it diversifies the sources of demand, capital and protection on which those sectors depend. Saudi Arabia’s progress is real; the financing transition remains incomplete.

Four meanings of “less dependent on oil”

Historical origin also needs separating from present dependence. A hotel initially built with oil wealth can later earn commercially sustainable income from foreign guests. An overseas financial asset bought with oil proceeds can deliver returns linked to other economies. Their origin does not make them permanently dependent on new oil receipts. The relevant test is continuing support and exposure, rather than the ancestry of the first investment.

2. The fiscal transformation is substantial—and unfinished

Collecting revenue from a broader base strengthens the budget. It does not automatically make the underlying demand independent of oil. A contractor can receive a publicly financed payment, pay employees, and generate taxable household spending. The final tax is classified as non-oil revenue even though part of the chain began with public expenditure. This is a transmission mechanism, not a measured estimate of how much tax revenue follows that route.

The accounts behind the headline

The contrast between 2024 and 2025 is particularly informative. Non-oil revenue increased only 0.6%, while oil revenue fell 19.8%. The non-oil share of total revenue consequently improved, even though non-oil spending coverage was approximately unchanged. A rising non-oil revenue share can reflect a smaller oil denominator as well as a stronger non-oil base.

This does not negate the decade’s reform. It identifies a better test: how much of a sustainable spending programme can non-oil revenue support over time? A share of receipts can improve while the state becomes more reliant on financing a shortfall.

The SAR 883.2 billion of 2025 expenditure not covered by non-oil revenue was met by SAR 606.5 billion of oil revenue and roughly SAR 276.6 billion of shortfall financing. Borrowing can bridge development and smooth shocks. It does not by itself demonstrate an independent revenue model, nor does its existence establish fiscal distress.

3. The 2026 shock exposes the difference between revenue and resilience

Inside the non-oil category, businesses performed differently:

This is the new economy’s central dilemma. Public spending can preserve businesses, employment and future capacity through a shock. At the same time, its stabilizing role makes it harder to infer autonomous commercial resilience from the fact that non-oil output stayed positive.

4. Aramco and PIF connect the old revenue engine to the new assets

The central budget captures only part of Saudi Arabia’s public investment system. PIF holds investments, deploys capital, recycles assets and raises financing through its own institutional structure. A study of oil dependence that examines only a ministry’s receipts misses an important transmission route.

This matters economically. A dividend paid on an oil-company share can support investment outside oil without first appearing as a new budget allocation to the fund. Moving ownership changes the recipient of future income; it does not change the business that produces it.

At a simple 16% proportional allocation, Aramco’s H1 2026 base dividends imply approximately USD 7.0 billion attributable to the PIF group’s transferred shareholding. This is an indicative calculation, not a separately disclosed PIF cash-flow line; treasury shares and distribution entitlements can affect an exact reconciliation. It should not be added to central-government oil revenue to produce a supposed total public revenue without consolidation.

A state can respond to a temporary distribution/cash mismatch using liquidity, borrowing, portfolio transactions and adjustments in investment or distributions. The analytical point is that the transition is financed by cash that must arrive when obligations fall due, rather than by an oil-price headline or net-income figure alone.

PIF is building a portfolio, not a second treasury cash balance

The critical distinction is between transforming wealth and needing recurring support. PIF can turn oil-linked assets into productive businesses whose future returns are less correlated with Saudi oil receipts. That is a plausible diversification mechanism. The question is whether investment returns and commercially earned revenue mature quickly enough to carry a larger share of ongoing funding needs.

5. Geography connects the financing problem to the Middle East’s security story

Selected Saudi economic nodes — approximate geographic references

An oil-export alternative is therefore an important buffer, but it does not make the country independent of regional conditions. Red Sea routes introduce different shipping exposures. Aviation, tourism and conferences depend on additional networks that a pipeline cannot substitute for.

The October airport incidents sharpen that distinction. The study cannot yet estimate their effect on fourth-quarter visitor receipts, investment or GDP; those data were not available at the cutoff. It can identify a credible mechanism: operational disruption and perceived risk can affect bookings, insurance, staff mobility and project execution. Establishing the size and duration of those effects requires subsequent observations.

For the new economy, regional stability is an economic input. It influences whether recently built assets can earn revenue, rather than merely how safely an existing commodity reaches market. This is the report’s inference from the financing structure and transport evidence, not an estimated security-risk coefficient.

6. Which new industries are moving towards independent earnings?

The answer varies within sectors as well as between them. A privately owned hotel with internationally diversified guests has a different exposure from a publicly anchored resort still building its customer base. Two AI facilities can look identical while one sells most capacity to outside customers and the other relies on an anchor public contract.

Tourism: a real export, with two distinct demand pools

The frequently cited 122.6 million combined 2025 trips should therefore not be read as 122.6 million foreign visitors. Nor should SAR 303.7 billion of spending be compared directly with the central budget’s non-oil revenue category as though they were substitute fiscal flows.

Inbound tourism demonstrates an earnings base outside direct oil sales. Its retained value depends on imports, wages, operating costs, debt service and the cost of maintaining facilities. Domestic travel can also save foreign exchange by replacing outbound travel, while remaining sensitive to resident incomes and public-demand conditions. International demand itself can be correlated with regional oil incomes if a large share of customers comes from neighbouring oil economies; this study does not estimate that share.

Saudi Arabia’s religious and cultural destinations provide differentiated reasons to visit. Access, capacity and security still matter. The commercial test is sustained visitor income and returns on invested capital across different oil and geopolitical conditions.

AI: oil-funded capital seeking an internationally saleable service

The announcement and authorization are different stages. Neither proves that all equipment has arrived, that the full announced capacity is operating, or that it has commercially profitable utilization. The counts should not be added together as separate installed fleets.

Saudi Arabia could convert financial resources and energy availability into an exportable computing service. That is a credible investment hypothesis. It also brings new dependencies: imported hardware, technology permissions, supplier support, connectivity, specialist labour and customer confidence. Local hosting does not remove these constraints.

The relevant economic unit is the return from useful computing sold or the productivity improvement delivered, after power, cooling, hardware replacement and financing costs. Announced megawatts alone cannot establish it. The regional competition is also visible in the same U.S. authorization covering both a Saudi and a UAE company: access to advanced technology is part of the Gulf’s economic diplomacy.

Construction, industry and clean energy: the customer matters as much as the sector

This table is an analytical framework, not a scored ranking or a measured allocation of oil dependence.

State support can be economically justified. Infrastructure, skills and new supply chains can require coordination that individual firms cannot provide. A premature withdrawal can destroy useful capacity before it matures. Equally, an attractive sector label does not establish additionality, productivity or a reasonable return. The transition succeeds when support produces capabilities and earnings that increasingly carry their own costs.

7. The budget and PIF strategy point towards a harder allocation problem

The underlying allocation challenge is straightforward. Saudi Arabia has to fund current services, security, infrastructure and new industries while preserving future wealth. It can raise taxes, borrow, use liquidity, recycle assets, sequence investment or seek partners. Each choice has a cost. Asset sales provide funding once; guarantees can make an investment financeable while leaving contingent exposure with the state; borrowing creates claims on future cash flows.

The question is therefore about the quality and timing of financial commitments, rather than a claim that the state is running out of all resources. More selective spending can improve the transition if it prioritizes assets with durable demand and achievable returns. It can also slow activity in firms whose orders depend on continued expansion.

8. A transparent stress test: how much can oil still change the arithmetic?

To make the exposure concrete, this study holds 2025 expenditure and non-oil revenue constant and applies hypothetical reductions to oil revenue. A second set of cases also reduces non-oil revenue. The exercise contains no forecast of oil prices, no estimated fiscal multiplier and no probability assigned to any outcome.

The formula and the calculation behind the scenario chart are:

# Lenz mechanical scenarios; SAR billion. Inputs: 2025 actuals, source S01.
# Fixed expenditure; no fiscal multiplier, policy response or probability.
expenditure = 1388.432
oil_revenue = 606.544
non_oil_revenue = 505.282

def revenue_shortfall(oil_decline, non_oil_decline=0.0):
    return (
        expenditure
        - oil_revenue * (1 - oil_decline)
        - non_oil_revenue * (1 - non_oil_decline)
    )

for oil_decline in (0.0, 0.10, 0.20, 0.30):
    print([
        round(revenue_shortfall(oil_decline, non_oil_decline), 3)
        for non_oil_decline in (0.0, 0.05, 0.10)
    ])

Lenz calculations. Holding expenditure constant isolates arithmetic exposure. Actual policy would adapt, and economic feedbacks could alter both receipts and spending.

A 20% reduction in oil receipts, with everything else fixed, adds approximately SAR 121.3 billion to the gap. Avoiding that increase entirely through expenditure adjustment would require spending approximately 8.7% below the baseline. This does not prescribe a spending cut; it quantifies the scale of the unchanged funding exposure.

The converse also matters. A temporary oil-price windfall can buy time to complete useful projects, protect employment and finance diversification. Spending an exceptional windfall on recurring obligations can increase exposure when prices normalize. Whether the shock helps the transition therefore depends partly on the commitments created with the additional income.

Price and volume should also be kept together. Gross sales value is price multiplied by delivered quantity. A higher price provides less protection when fewer barrels can be shipped, while public receipts also depend on costs, taxes, royalties, distributions and timing. This is why this study does not present a single oil-price “break-even” as the measure of Saudi economic independence.

9. Three regional paths—and the evidence that would distinguish them

The developing Middle Eastern story brings oil markets, transport security and technology access into the same investment decision. Saudi Arabia’s new assets need capital to be built, access to international inputs, and customers willing to use them. The regional environment can affect all three together.

These are analytical paths, not exhaustive or mutually exclusive forecasts. Their purpose is to identify observations that would support or weaken the thesis.

The second path contains the report’s central tension: a crisis can increase the importance of oil income precisely when it makes the non-oil investment model harder to operate. The first and third paths show why the conclusion is not predetermined. Commercially successful assets can become more independent; easier operating conditions can coexist with a tougher financing constraint.

The study would become more optimistic if non-oil receipts consistently covered a larger proportion of a sustainable spending base, if PIF’s mature investments generated more usable cash from diversified earnings, and if externally earned business income expanded without proportionate increases in recurring support. It would become more concerned if growth required steadily larger public commitments while returns, utilization and customer demand disappointed.

The next research dashboard should measure earnings and exposure

These are meaningful capabilities and financial relationships. They also explain why a simple binary judgement would miss the transition: the task is to convert a state-supported expansion into a more durable combination of productive assets, diversified income and commercially sustained demand.

10. The finding for Lenz

Saudi Arabia’s diversification should be assessed at the point where new activity becomes durable earnings. Counting a larger non-oil sector captures part of the transformation. Following who finances it, who buys from it and what keeps it operating captures the next part.

The directly measurable answer remains substantial: oil supplied 54.6% of central-government receipts in 2025, and non-oil revenue covered 36.4% of expenditure. The wider economy’s dependence cannot responsibly be reduced to that same percentage. It runs through contracts, ownership, credit, customer demand and exposure to regional conditions.

The Middle East’s current conflict makes those channels easier to see. Oil infrastructure can preserve income through alternative routes and higher prices. Newer industries often need predictable connections, international technology and confidence. Public capital can bridge the difference, but its success will be demonstrated by the returns and capabilities that remain after the bridge is needed less.

The decisive milestone is an expanding set of Saudi businesses that can thrive through a weaker oil cycle and a less accommodating public investment cycle. That is where diversification becomes resilience.

Research design, definitions and limitations

Type of study. This is a descriptive, document-based financial and political-economy study. It combines official fiscal accounts, national accounts, institutional disclosures and dated event reporting with explicitly labelled Lenz calculations and scenarios. It does not estimate a causal fiscal multiplier, conduct an enterprise survey or value individual projects.

Evidence hierarchy. Official statistical and fiscal tables take precedence over rounded secondary reports. For example, the primary Q4 fiscal report records 2025 non-oil revenue as SAR 505.282 billion. Some secondary summaries print different rounded figures; they are not used. GASTAT’s September detailed Q2 estimate takes precedence here over earlier flash values. Company statements are attributed to their issuers, and self-reported impact claims are distinguished from independently reconstructed measures.

Coverage. The main fiscal series is central government, on the MoF’s cash basis and classification. It is not a consolidated account of the budget, PIF, all state enterprises and the entire financial system. Investments, intra-public-sector payments, guarantees and liabilities would require consolidation before being aggregated. Gross issuance is also different from a deficit because refinancing and other financing needs can occur.

Periods and vintages. 2025 is the latest complete fiscal year used. H1 fiscal observations and Q2 national accounts are presented separately. The September 2026 pre-budget statement provides estimates and preliminary plans. The July IMF outlook has a different information set and assumptions. October airport events occurred after the latest quarterly GDP observations, so their realized macroeconomic consequences are not inferred from Q2 data.

GDP measurement. Real growth rates use the publication’s chain-linked measures. The MoF’s reported 57.3% real non-oil share is reproduced with attribution; it is not combined with fiscal ratios to construct an “independence index.” Chain-linked components and official activity groupings need care when forming shares or adding components. A rise in a non-oil share can also reflect a contraction in oil output rather than an equivalent increase in independent non-oil capability.

Currencies and rounding. Fiscal data are presented in SAR billion; Aramco and PIF figures are in USD where labelled. Illustrative conversions use SAR 3.75 per USD, the conversion basis in Aramco’s interim disclosure. Totals and percentages are calculated from the accompanying unrounded inputs where available. Small reported accounting differences from rounding are retained and documented rather than silently “corrected.”

Tourism and investment. Visitor spending is not GDP or government revenue. Trip counts can include repeat visits and the domestic and inbound components must be separated. FDI is a capital relationship, not a sales receipt; net FDI, gross inflows, asset acquisitions and greenfield investment cannot be substituted for one another. Announced AI capacity and licensed chips are not installed or utilized production.

Identification limits. Positive non-oil GDP during the shock demonstrates resilience in observed activity, but cannot isolate the contribution of government support or exclude other drivers. The reviewed sources do not identify the proportion of each firm’s revenue traceable to oil-funded demand. Public ownership does not establish permanent dependence, and private ownership does not establish autonomous demand.

Maps. The two map blocks follow Lenz’s country-map schema: YAML fields with inline CSV containing iso3,value,label. The first maps Saudi Arabia’s national fiscal oil share; it does not estimate subnational dependence. The second highlights six countries for geographic reference, with 1 meaning included rather than a measured risk score. Selected Saudi nodes retain approximate longitude and latitude in a table, and route relationships use editable Mermaid code blocks. Route diagrams are schematic, not surveyed alignments, navigation tracks, project boundaries or live conditions. The supporting GeoJSON files preserve the original reference coordinates.

Reproducibility. The file embeds all 29 bibliography entries as CSL references in YAML front matter and uses the native [@saudi-s01] citation convention throughout the narrative. Keys are specific to this Saudi study to avoid collisions with other reports. Ten chart blocks, one four-card stats block and two map blocks contain inline data; three Mermaid code blocks preserve conceptual and route relationships, and a Python block reproduces the fiscal scenarios. Percentage-formatted values are fractions: 0.364 represents 36.4%. Monetary units are stated in each subtitle. No images are embedded. Supporting observations, source metadata and original geographic coordinates accompany the research folder.

Source register

All sources were reviewed or their specified indexed official statements checked by 14 October 2026. Source-specific access notes, periods, locators and limitations are recorded in the accompanying register. “Actual” is the issuing authority’s reported result or estimate of an observed period, rather than a claim that data cannot later be revised.
