A structural read of trade fragility — why the volume dial reassures while the system stretches
Illustrative research draft · directional structural read · built on public data · not a dated forecast
When people ask whether global trade is fragmenting, they watch volume — and volume looks fine. Our reading is that volume is the wrong first dial. Fragmentation does not arrive as less cargo carried; it arrives first as rising variance in whether, when and by which route cargo moves, and as distance quietly substituting for trust. This report reads the shape and mechanism of that change — not a dated prediction of decline. The question throughout is shock-readiness: what the trade system would absorb, and what would find its exposed flank. Every figure is public and sourced; nothing here is a validated forecast.
Solvency: sound
fleet, ports, order books are immense
Coherence: watch ↓
variance up; distance replacing trust
Exposed flank: the trust layer
sanctions/insurance/payments, not physics

How to read: this is a directional read of fragility’s shape — where variance concentrates and which buffers it consumes — not a forecast of trade volume or of any single disruption. We do not date anyone’s decline.

Read this first

What this is. A worked example of the TGH health lens applied to the world trade system. Read the lens first; weigh the reading second. It is a structural, directional read — the shape and mechanism of what is changing — not a dated prediction and not an out-of-sample validated result. Two technical terms are used and each is given a plain meaning where it appears.

A system is healthy not when its output holds, but when it still works as one purposeful whole — when effort is not rising faster than what that effort delivers. Global trade’s output is holding. Its effort is rising. That gap is the whole story.

The dial everyone watches, and the dial that moves first

The natural dial is volume: total goods moved, year over year. On that dial the story is reassuring — world merchandise-trade volume grew about 4.6% in 2025, well above the ~2.4% the WTO had forecast, lifted by demand for AI-related goods. Nothing resembling collapse.

Our reading is that volume is the wrong first dial. Fragmentation does not arrive as a steady decline in how much is carried. It arrives first as rising variance in whether, when, and by which route it is carried. A system losing its integration does not ship less at first — it ships the same amount with more drama: wider swings in transit times, sharper insurance repricing, more re-routings, longer and less predictable queues. The mean holds while the spread around the mean widens.

The recent record reads this way exactly. Within a few years the system absorbed a pandemic whiplash in container demand, a war reshaping energy cargoes, attacks that emptied a primary chokepoint, and drought constraining another. In the first two months of 2024, traffic through the Suez Canal fell roughly 50% year-on-year and the Panama Canal about 32%; both ran more than 40% below their recent peaks, and Panama’s drought cut daily transits from a normal ~38 to about 24 by late 2023. Each event was absorbed; volume recovered each time. But the shape changed — and the clearest measure of it is reliability. Container schedule reliability (the share of ships arriving when promised) ran near 78% before the pandemic, fell to roughly 50–55% across 2024 (53.8% in December 2024), recovered to 65–68% through 2025, and opened 2026 at 62.4%. The width of that swing, not its level, is the signal.

The honest limit of that signal, stated plainly: schedule reliability swings hardest during shocks and recovers between them, so a wide swing alone is consistent with ordinary shock-and-recovery, not only with secular decline. The decisive test — the one this report has not yet run on itself — is whether the baseline variance between shocks is creeping up, not merely whether the spikes are large. We flag that as the first thing to check, and as a falsifier below.

Why variance matters: it consumes buffers quietly. Every re-routing, every congestion episode, every insurance spike draws down slack — financial, physical, human — that does not show on the volume dial until the slack is gone.

What reorganisation looks like at sea

The second reading concerns what the responses themselves mean. Re-routing around the Cape, friend-shoring of supply chains, “de-risking”, near-shoring, the duplication of supplier networks across political blocs — usually reported as separate cost stories, these are structurally one story: this is what it looks like when an integrated system reorganises into something less integrated, while staying busy throughout.

Integration was never just infrastructure. The efficient trade web of recent decades rested on an assumption so reliable it became invisible: that any cargo could move between almost any two points, and the political layer would not interfere. What is being withdrawn now is not capacity — ships and ports still exist — but that assumption. And the data shows trade redrawing itself around trust lines rather than cost lines: over 2017–23, trade volumes grew about 2.5% more slowly each quarter between geopolitically distant countries than between close ones, and at the peak in late 2022 trade between non-aligned blocs had fallen about 15%. Friend-shoring is not a policy fashion; it is the visible surface of a network deciding anew who is inside and who is outside — a process that can run for years while every actor behaves rationally and every quarterly report looks ordinary.

The tonne-mile paradox

Here the reading turns uncomfortable, because the industry’s best year can be the system’s worst signal. A tonne-mile — one tonne of cargo carried one mile — is shipping’s basic unit of demand. When routes lengthen, tonne-miles rise even if not one extra tonne is traded. In 2024, vessel re-routing pushed ton-mile demand to a record +6% — almost three times the growth in trade volume — as ships diverted around the Cape of Good Hope (arrivals there surged 89%); Clarksons logged the strongest tonne-mile growth in over a decade.

The paradox: tonne-mile demand can boom precisely because the system is becoming less coherent. Distance is substituting for trust. Every extra mile on these routings is a mile the world is paying to avoid a counterparty, a strait, or a jurisdiction it no longer relies on. The freight earnings are real — but structurally they are the fee the system pays for its own disintegration, booked as growth.

Two mechanisms, not one — and they reverse differently. Honesty requires splitting that phrase. Some of the extra distance is reversible security-shock re-routing — ships going around the Cape because the Red Sea is dangerous — and it snaps back the day the strait is safe. The rest is persistent trust-withdrawal — trade redrawing itself along bloc lines, cargoes detouring around whole jurisdictions, the shadow fleet leaving the shared system — and it does not reverse when one shock ends. Only the second is genuine disintegration; the first is absorption, at cost. This report’s directional claim rests on the second, and a careful reader weighs the two apart rather than reading all the extra distance as decay.

This is why volume-watchers and coherence-watchers look at the same ocean and disagree. Volumes stable, tonne-miles up, fleets busy: by the stores, the system is sound. The same numbers read the other way say the system is working harder, over longer distances, at higher insurance cost, with more variance, to deliver the same underlying trade. Effort is rising faster than output — and that ratio, not the output line, is where erosion shows first.

Two clocks on the trade system

We read any system on two clocks: a solvency clock (the stores — what has been built and earned) and a coherence clock (whether the system still works as one purposeful whole). They can run decades apart, and the gap between them is where masked decline hides.

Solvency: sound

Fleet capacity, ports, shipbuilding order books, the institutional architecture of trade — these stores are immense and not in question. The world fleet reached about 112,500 vessels and 2.44 billion deadweight tonnes by January 2025 (up from 2.35 billion a year earlier), and the container order book hit a historic high, with 4.4 million TEU contracted in 2024. Nothing here would trouble anyone — which is exactly why it proves little: stores measure what was earned, including what was earned under conditions that no longer hold.

Coherence: watch, trending toward concern

Four lines, the same four we read in any institution:

Purpose vs behaviour
The stated frame is still open, rules-based trade; the allocation record — tariffs, export controls, subsidy races, bloc-aligned investment — increasingly says otherwise. New trade barriers introduced each year have roughly tripled since 2019, to almost 3,000 in 2022. The gap between the system’s language and its behaviour is itself a measurable burden: every actor must now hedge against the difference.
Does the system learn from its shocks, or pay them off?
After recent chokepoint and pandemic shocks the pattern is the same — congestion clears, surcharges fade, concentration quietly resumes. The signals are being paid off rather than heard.
Are durable relationships renewed, or consumed?
Long-term contracts, alliance structures and trusted-counterparty relationships are the trade system’s durable bonds. Where chartering and procurement shift toward shorter commitments and spot opportunism, those bonds are being consumed, not renewed — and consumed bonds pay out until they are suddenly gone. (The precise contract-vs-spot mix is the one input here still to be hard-sourced — see the open questions below.)
Where does effort evaporate?
Resilience spending that buys real optionality is investment; resilience spending that duplicates capacity without reducing exposure is evaporation. The test for any programme is whether it lowers the variance above — much announced “de-risking” has yet to show that it does.

Shock-readiness, by shock type

The two clocks combine into the reading that matters operationally — not when something breaks, but what kind of shock this system absorbs and what kind finds the flank:

Capacity & weather shockslikely absorbed
Storms, droughts, congestion, even canal closures: the stores are built for physics, and the record shows repeated absorption, at cost.
Single-chokepoint geopolitical shocksabsorbed at rising cost
Re-routing works — that is what the tonne-mile data shows. But each absorption spends buffer and lengthens the system’s average distance: absorption that leaves the system more stretched than before the shock.
Trust-layer shocksthe exposed flank
A shock that requires the network to be believed at speed — a sanctions cascade fragmenting the insurance and payments layer, a flag-state or classification credibility failure, a forced sudden choice of bloc by major intermediaries — draws on exactly the bonds this reading marks as thinning. The physical fleet would be untouched; the agreements that let it move would not. Distance cannot substitute for trust when it is trust itself that is called. A visible down-payment on this risk is already afloat: the “shadow” tanker fleet moving sanctioned oil outside the mainstream insurance-and-flag system grew from about 787 tankers (8.5% of the world fleet) in May 2024 to roughly 978 tankers by September 2025 — that share of the system has already left the shared trust layer.

What an operator should monitor

The principle in each case is the same: track variance and renewal, with thresholds agreed in advance. A threshold crossed is a fact; a mood is not.

A shipping company: the spread, not just the level — variance of transit times and schedule reliability on your trades against a fixed baseline; your own contract-versus-spot mix as a relationship-renewal indicator (are counterparties re-choosing you, or are you both just riding switching costs?); the share of revenue earned from deviation (re-routing, compliance premiums) versus carriage — the tonne-mile paradox on your own income statement.

A port: dependency concentration — share of throughput tied to a single chokepoint, lane or transshipment partner; hinterland diversity; call-pattern variance. A port can gain volume from re-routing and simultaneously become a more exposed node in a thinner network.

An insurer: the dispersion of war-risk and chokepoint premiums across routes as a live map of where the market prices withdrawn trust; the growth of the uninsured or alternatively-insured fleet as a measure of how much of the system has already left the shared trust layer; and the correlation of exposures that were priced as independent when the network was more integrated.

How this reading was produced

Be clear about the evidence. This is a structural, directional read — the same lens used on institutions and states, applied to the trade system, built entirely from public data (the figures above and their sources below). The canvas modelled is deliberately bounded: the economic, trade and geopolitical layers of the system — flows, routes, chokepoints, contracts, blocs — not the whole of world politics. Within that canvas the method’s natural mode is to run the system forward and back over time to read the trajectory — whether variance, the tonne-mile gap, the bloc divergence and the trust-layer exposure are widening or narrowing — rather than to score a single snapshot. That trajectory reading is the directional claim; it is not a dated forecast, and it has not been validated against held-out outcomes. Be clear about what stands behind it: this report is a hand read on public data — an analyst applying the lens, not the output of a model run. The forward-and-back trajectory described above is how the method would read this canvas in the engine; that engine reading has not been done for trade, so nothing here rests on a simulation and we make no engine claim for it. Treat the directional shape as the claim, not any single number.

What this reading is, and is not — with its falsifiers

This is a directional, structural read: fragmentation arriving as variance before volume, reorganisation visible as re-routing and friend-shoring, distance substituting for trust, the trust layer as the exposed flank. It is not a dated prediction, and it carries its own falsifiers, stated so they can be checked later:

The reading is wrong if: disruption variance subsides toward its pre-2020 baseline while volumes hold; tonne-mile growth reconverges with tonne growth without new political-risk premiums; cross-bloc trade re-accelerates relative to within-bloc trade; or the shadow-fleet share stops growing and re-enters the mainstream trust layer. If the variance measures do not in fact widen while volume holds, the central claim of this report fails — and that is the line to test first. One caution on our own evidence: the 2017–24 window we draw on (pandemic, Ukraine, Red Sea and Panama stacked together) is the most fragmentation-flattering stretch in two decades; if the structural signal is real it should persist as those specific shocks fade — and if it does not, it was shock-stacking, not disintegration.

Misses and open questions

A standing section of every report: what we looked for and did not fully find, and what this method cannot read. It is not a disclaimer; it is where the reading earns its trust.

#Open item
1This is fragility shape, not a volume forecast. It reads where variance concentrates and which buffers it consumes — not a dated prediction of trade volume or of any single disruption.
2One figure not yet hard-sourced. The contract-versus-spot mix (the bond-renewal indicator) is argued directionally here; the specific series is the next data point to fill before this section is final.
3Framework-derived, not engine-run. The mechanism (shock-readiness governed by internal condition, not shock size) is derived from the project’s framework; it has not been run in the engine for this trade canvas and has beaten no out-of-sample baseline. (Consistent with the method note above: a hand read on public data, not a model output.)
4Conduct over words. Where the report reads institutional or operator intent, it is anchored in observed routing, pricing and capacity behaviour — not in stated policy.
5Two mechanisms under one phrase. “Distance substituting for trust” fuses reversible security-shock re-routing (Red Sea→Cape, which snaps back when the strait is safe) with persistent trust-withdrawal (bloc divergence, the shadow fleet). Only the second is structural decline; the report’s claim rests on it, and the two should be weighed apart.
6The “trust layer” is several mechanisms, not one — insurance, sanctions compliance, payments, flag-states, classification — bundled here for brevity, with the shadow fleet as the cleanest single proxy. And that fleet may be a new parallel trust system forming, not only the old one being left.
7“Effort evaporating” may be purpose changing. Duplicated supply chains read as waste only if efficiency is the system’s purpose; an order deliberately buying resilience or sovereignty is purchasing a different purposeful whole. The lens reads coherence against an assumed purpose and cannot yet adjudicate between competing valid purposes.
8Bloc divergence may understate connector economies. Trade rerouted through third countries (Mexico, Vietnam, India) keeps the underlying relationship alive while changing its recorded path — so some “decoupling” is re-labelling, not severance.
