Budget Space: The Leading Variable of the Investment Cycle

In any investment spending cycle, a gap emerges between commitment and payment. Orders are signed, envelopes are announced, then disbursements follow with a more or less lengthy delay. This lag depends on technical factors, such as suppliers' production capacity, authorization timelines or labor availability, but also on a more structural constraint: the financial solidity of the state that subsidizes, guarantees or directly orders.

In the absence of homogeneous and comparable series on industrial order books at the international level, the analysis must rely on an indirect but robust indicator: the trajectory of public debt. IMF projections for 2031 offer a forward-looking snapshot of the budget space of major economies. They do not measure investments themselves, but they delineate the perimeter within which those investments can actually be paid.

The working hypothesis is simple: the higher the projected net debt, the greater the risk that public or subsidized investment commitments will be revised, spread out or partially abandoned along the way. The divergence between order books and actual disbursements would then be less an industrial phenomenon than a budgetary one.

Three Blocks of Trajectories

Economies with Limited Margin

Four major economies exceed the 110% of GDP threshold in projected net debt by 2031. Italy leads with 126.7%, for a gross debt of 136.1%. Japan follows with net debt of 122.8%, but gross debt peaking at 192.8% of GDP, the highest level in the panel. The United States stands at 115.4% net and 142.1% gross, while France reaches 112.6% net debt.

For these countries, every industrial investment program competes directly with debt servicing. Announcements may remain ambitious, but execution is exposed to annual arbitrations. It is typically in this configuration that the gap between commitments and payments tends to widen: multi-year envelopes are voted, then payment credits are trimmed to meet deficit targets.

The Intermediate Zone

A second group sits between 55% and 95% net debt. The United Kingdom shows 94.5% net and 102.6% gross, at the edge of the first block. South Africa, at 81.5% net debt for 82.6% gross, and Brazil, at 81.1% net, present comparable levels but in a financing environment generally more costly for emerging economies. Germany, at 60.7%, and Mexico, at 55.6% net and 63.6% gross, have more comfortable latitude.

The German case deserves particular attention: among the major European economies in the panel, it has the lowest projected net debt, far ahead of France and Italy. This position theoretically gives it a superior capacity to convert its industrial commitments into actual spending, without facing the same adjustment pressure.

Economies with High Disbursement Capacity

The third group brings together countries whose projected net debt remains below 45% of GDP. Canada stands out with only 10.4%, followed by South Korea at 12.9%. Turkey sits at 23.0% net and 27.5% gross, Australia at 30.7%, Saudi Arabia at 34.6% net and 42.2% gross, and Indonesia at 40.7%. Russia, for which only gross debt is available, shows 29.1%.

These economies have, on paper, the strongest budget capacity to support long Capex cycles. But low indebtedness does not guarantee smooth execution: exchange rate constraints, access to imported equipment or administrative capacity can also widen the gap between orders and disbursements.

The Gap Between Gross and Net Debt: A Revealer of Mobilizable Assets

The difference between gross and net debt provides information on the financial assets held by public administrations. It constitutes a valuable indicator of the capacity to finance investments without resorting massively to new borrowing.

Two cases stand out clearly. Japan shows a gap of about 70 percentage points of GDP between its gross and net debt, and South Korea a gap of about 50 points: its projected gross debt of 63.1% contrasts sharply with net debt of only 12.9%. The United States follows with a gap of nearly 27 points.

Conversely, South Africa shows a gap of only about 1 point, Turkey about 4.5 points. For these countries, gross and net debt are almost indistinguishable: there are few public financial reserves available to absorb a shock or accelerate an investment program. Disbursements there depend more on the capacity to borrow on markets at the right time.

The United Kingdom and Mexico share an identical gap of about 8 points, Italy a gap of about 9.4 points and Saudi Arabia about 7.7 points, modest cushions relative to their respective debt levels.

What This Implies for the Divergence Between Orders and Payments

Cross-referenced with the logic of investment cycles, these trajectories suggest a differentiated reading. In the economies of the first block, the main risk is that of spreading out: order books may remain full, but the pace of public payments slows under budget pressure. For supplier manufacturers, this translates into inflated order books but slower conversion into revenue.

In the intermediate block, the decisive variable is the cost of financing. A comparable debt level does not have the same consequences in South Africa or Brazil as in the United Kingdom, and programs there are more sensitive to monetary conditions.

In the third block, the budget constraint fades in favor of physical and operational constraints. This is where the gap between orders and disbursements most faithfully reflects industrial bottlenecks themselves.

Signals to Watch

To anticipate the effective materialization of Capex cycles, three signals merit regular monitoring. First, successive revisions of debt projections: a rise in anticipated net debt in first-block countries generally precedes cuts in payment credits. Second, the evolution of the gap between gross and net debt, which indicates whether states are drawing on their reserves to finance their commitments. Finally, the comparison between investment announcements and the budget calendar actually voted.

The geography of industrial investment over the next decade will not be read only in order books. It will also be read, and perhaps above all, in public balance sheets.
