A distributor of industrial components has one primary supplier — a manufacturer in Southeast Asia. In March, new tariffs take effect that raise the cost of the supplier’s components by 28% overnight. The distributor cannot pass the full increase to customers without losing its largest contract. In April, a typhoon causes a three-week production shutdown at the supplier’s facility. The distributor’s domestic inventory runs out in week two. Orders go unfulfilled. Revenue stops. In May, a new geopolitical development triggers port delays that extend the production shutdown’s ripple effect by another two weeks.
The distributor’s business interruption coverage does not respond to any of this. Standard BI requires direct physical damage to the insured’s own property as a prerequisite for coverage. No damage occurred at the distributor’s location. The supply chain disruption — the tariff increase, the supplier’s production shutdown, the port delay — falls entirely outside the coverage grant. Five weeks of lost revenue, accumulated inventory write-downs, and a damaged customer relationship: none of it insured.
This is not an edge case. It is the normal operating environment for mid-market companies in 2026, and the gap between what standard business interruption covers and what supply chain disruption actually costs is one of the most significant uninsured exposures in commercial insurance.
What Standard Business Interruption Was Designed For
Business interruption insurance was designed for a specific scenario: a covered peril — fire, windstorm, explosion — damages the insured’s property and prevents operations. The BI coverage replaces lost income and covers ongoing fixed expenses during the period of restoration. It is essentially a loss-of-revenue coverage attached to a property claim, which is why it requires direct physical damage as a trigger.
That design made sense when supply chains were local, when most businesses depended on their own facilities for their productive capacity, and when the primary business interruption risk was a fire at the factory rather than a disruption at a facility twelve time zones away. The world changed. The coverage structure did not.
The Three Macro Forces Creating Uninsured Supply Chain Exposure
Geopolitical conflict and trade policy volatility are the first force. The combination of active conflicts affecting shipping lanes, shifting tariff regimes, and export control restrictions has made supply chain disruption an expected operating condition rather than an exceptional event for many mid-market manufacturers, distributors, and importers. A business whose supply chain runs through Eastern Europe, the Taiwan Strait, or key chokepoints in global shipping routes is exposed to interruption from causes that standard commercial property and BI policies were never designed to address.
The tariff environment specifically creates a cost-volatility exposure that overlaps awkwardly with business interruption. When a tariff spike makes a previously viable supply chain economically non-viable, the business faces an interruption of its cost model without any interruption of its physical operations. That exposure does not fit cleanly into any standard commercial insurance product.
Secondary weather perils are the second force. Inland flooding, severe convective storms, and extreme heat events are disrupting supply chains at locations that are not the insured’s own facilities. A cold storage facility loses inventory because a power grid serving the region fails during an extreme heat event. A distribution center cannot receive inbound shipments because a secondary road network was damaged by flooding that did not touch the distribution center itself. These are supply chain interruption losses with weather origins — but because they do not involve physical damage to the insured’s own property, standard BI does not respond.
Concentration risk is the third force. Mid-market companies that have optimized their supply chains for cost efficiency have frequently concentrated sourcing in single suppliers or single geographic regions. That concentration delivers cost savings in stable conditions and catastrophic vulnerability in disrupted ones. The pandemic demonstrated this at scale. The current geopolitical and weather environment is demonstrating it again, in slower motion, across a wider range of industries.

The Coverage Structures That Address Supply Chain Risk
Businesses with material supply chain exposure should consider three different coverage structures. Each responds to a different kind of loss, and the policy wording determines what is covered.
Contingent business interruption (CBI) may protect lost income when physical damage at a covered supplier’s or customer’s location interrupts your operations. A typhoon that damages a supplier’s factory is the type of event to examine under CBI. A tariff increase, on its own, generally is not. The supplier or customer, covered cause of loss, waiting period and applicable limit all matter.
Supply chain insurance may address selected interruptions that do not involve physical damage. Depending on the policy, these could include logistics disruption, supplier insolvency or certain political events. Coverage is less standardized than CBI, so businesses should compare the named triggers, exclusions, method of calculating losses and sublimits against their actual suppliers and shipping routes.
Trade credit insurance addresses receivables risk. If a customer cannot pay because of insolvency or prolonged default, a trade credit policy may protect the seller’s unpaid invoices, subject to its terms. It serves a different purpose from coverage for the seller’s own interruption. Allianz Trade

Frequently Asked Questions
What is contingent business interruption coverage and how does it differ from standard BI?
Standard business interruption requires physical damage to the insured’s own property as a trigger. Contingent business interruption extends coverage to income losses caused by physical damage at a supplier’s or customer’s location — a covered loss at a vendor facility that prevents the insured from operating. CBI does not cover non-physical interruptions such as tariff changes, geopolitical disruption, or supplier insolvency.
Does business interruption insurance cover supply chain disruption caused by tariffs?
Standard business interruption and contingent business interruption policies do not cover supply chain disruption caused by tariff changes, trade policy volatility, or geopolitical events because these are not physical loss triggers. Supply chain insurance, a distinct product class, can be structured to cover non-physical interruption triggers, but coverage terms, triggers, and availability vary significantly by carrier.
What is trade credit insurance and when does a business need it?
Trade credit insurance protects a business against non-payment by customers — specifically, losses arising from customer insolvency, protracted default, or in some policies, political risk affecting the customer’s ability to pay. It is relevant for businesses that extend meaningful credit terms to customers, particularly in industries or geographies where customer financial distress or supply chain disruption could impair payment capacity.
