BIS Finds Inventories Cushion Chokepoint Shocks but Raise Input Costs
A BIS Bulletin says substitution and inventory buffers can reduce output losses from geopolitical disruptions at critical transport and trade chokepoints, often at the cost of higher input prices.
What the BIS published
Source publication date: October 15, 2026. BIS Bulletin 138 examines how geopolitical tensions, trade restrictions, and conflicts disrupt global supply chains at critical chokepoints. Its key takeaways are that substitution and inventories have helped mitigate adverse output effects, frequently with higher input prices, and that effective responses depend on the cause and centrality of the disruption and the private sector's ability to use substitutes and buffers. The authors' views do not necessarily represent the BIS or its member central banks.

Physical continuity and financial resilience are different
A company may keep producing by rerouting freight, changing suppliers, expediting shipments, or carrying more inventory, yet each response can require earlier cash outlays, larger deposits, longer in-transit periods, higher insurance and storage costs, or lower margins. Output may therefore appear stable while liquidity tightens. Aggregate research cannot determine whether a specific substitute meets technical, regulatory, customer, quality, or contractual requirements.
Chokepoint exposure extends beyond direct importers
Manufacturers, wholesalers, retailers, contractors, fleets, equipment operators, and commercial-property tenants may depend on components, fuel, packaging, maintenance parts, or customer flows that pass through concentrated routes. An indirect supplier can create as much operational risk as a direct shipment. Borrowing-base availability may also lag the cash need if in-transit, foreign, consigned, slow-moving, or customer-specific inventory is ineligible or subject to reserves.
Practical borrower takeaway
Map tier-one and critical upstream suppliers, countries, routes, ports, lead times, Incoterms, deposits, currency, duties, insurance, and alternative specifications. Quantify minimum and maximum buffer stock, storage capacity, obsolescence, and financing eligibility. Build a 13-week cash case for delay, rerouting, expedited freight, higher purchase cost, and slower customer pass-through. Support any revolver or term-loan request with documented purchase commitments, inventory controls, margin protection, and a credible normalization path.
Importers, manufacturers, distributors, and transport borrowers should map critical routes and suppliers, quantify buffer-stock cash needs, and test margin and liquidity under delayed shipments and costlier substitutes.
