Zinc Concentrate Financing: When the Collateral Moved, the Line Disappeared
Quote from chief_editor on May 21, 2026, 3:30 pmCommodity trade finance lines backed by metal in transit become unsecured the moment the metal moves to a jurisdiction the bank can't control.
A mid-sized zinc concentrate trader had a revolving trade finance facility backed by the value of metal in transit. The bank would advance up to 75% of the invoice value of zinc concentrates from the moment of vessel departure from the load port through to the moment of payment receipt at the destination. The structure worked cleanly for 18 months.
Then the trader moved a cargo through a port in a jurisdiction the bank had recently added to its enhanced due diligence list. The bank's internal compliance review flagged the transit routing. The advance on that cargo was frozen. Two subsequent cargoes using the same routing were declined. The bank initiated a facility review. Over the next six weeks, the facility was not formally cancelled, but advances were not being made while the review was ongoing.
The trader had three cargoes on the water, a fourth at the load port ready to ship, and a payment due to their supplier in 14 days. The facility that was supposed to fund operations was functionally unavailable. The trader scrambled for alternative financing at significantly higher cost and found partial coverage. The fourth cargo delayed its departure while financing was arranged, which triggered demurrage on the chartered vessel.
The Collateral Exists But the Control Does Not
The fundamental challenge with using in-transit commodity inventory as loan collateral is that collateral control diminishes progressively as the cargo moves away from origin and toward a destination that may be in a different jurisdiction, under a different legal system, and physically inaccessible to the lender.
When a zinc concentrate cargo is at the load port in Peru, the bank can in theory direct its disposal — the cargo is in a stable location, in a jurisdiction with functioning commercial courts, and the bill of lading controls access to the goods. As the cargo moves onto a vessel crossing the Pacific, the cargo exists and is technically controlled by whoever holds the original bills of lading, but physical access is limited. When the cargo arrives at a Chinese port and is discharged into a bonded warehouse pending payment, the bank's practical ability to enforce against the collateral depends on Chinese law, Chinese court procedures, and relationships with the warehouse operator — none of which are within the bank's normal operational reach.
Industry estimates suggest that in commodity trade finance, the effective value of in-transit collateral from the lender's perspective decreases as the cargo moves toward a discharge destination in a jurisdiction with less developed commercial enforcement infrastructure. Banks that do not formally model this risk often discover it when they need to enforce — by which point the collateral is in a jurisdiction where enforcement is slow, expensive, and uncertain.
The trader in the example above did not change their operations to trigger the bank's compliance review — they were using a routing that had been unproblematic for 18 months. The bank's internal policy changed, and the change was not communicated in advance. This is a recurring pattern: facility structures that worked under one bank policy framework become problematic when the bank's internal risk or compliance parameters shift, without any change in the trader's operations.
Building for Facility Continuity
Traders who rely heavily on revolving trade finance facilities for working capital should understand that these facilities can be functionally unavailable even without being formally cancelled. Events that trigger this include: bank compliance reviews, jurisdiction additions to enhanced due diligence lists, commodity price drops that reduce advance rates, counterparty credit deterioration, and broad portfolio-level risk reduction decisions by the bank.
The practical question for a trader dependent on such a facility is: what is the backup plan when the facility is functionally unavailable for 30 to 60 days? Traders who have a credible answer to that question — a secondary banking relationship, a factoring line, equity reserves — can manage the gap. Traders whose entire working capital structure depends on a single facility discovering it is unavailable are in a structurally fragile position that the profitability of the preceding 18 months of smooth operation does not resolve.
