String Trades and Trade Credit Insurance After the Litigation Wave

What a string trade is, and why it exists

A string trade (also called a flash trade, a structured trade or a back-to-back chain) is a sequence of sales of the same cargo between intermediaries while the goods are in transit. A trader buys a cargo and sells it on almost immediately, typically on deferred terms such as 90 days. The next trader does the same. Eventually the physical cargo reaches the end buyer, while each intermediary holds a receivable it can finance in the meantime.

The commercial logic is liquidity. Each participant discounts or borrows against its receivable and puts the cash to work for the deferral period. In some variants the chain is circular, with the cargo returning to the party that started it, or goods pass between group entities to extend credit to a buyer. All of these structures share one exposure. If the buyer at any link defaults inside that 90 day window, the seller holds an unpaid receivable, and frequently a lender holds a claim against that seller.

Trade credit insurance was the tool most mid-sized traders used to manage that exposure, either through a whole-turnover policy or single-buyer cover. It also underpinned financing, because receivables lenders often required the policy to be assigned to them or to name them as loss payee.

Why the claims ended up in court

When the pandemic liquidity squeeze pushed a cluster of smaller traders into insolvency, some of the failures exposed large-scale fraud, including duplicated or fabricated documents. Insurers facing claims on string trades began questioning whether those transactions were ever within the scope of what they underwrote.

The insurer position, broadly, was that their policies assumed a trader would take actual or constructive control of the goods, and that some policyholders could not link themselves to a real shipment, relying instead on copy documents or, in the worst cases, forged ones. Traders responded that back-to-back chains are standard market practice, that any underwriter familiar with commodities knows intermediaries rarely hold the cargo, and that if the policy wording did not fit the business, the broker should have placed different cover.

Outcomes differed by jurisdiction and by facts. What emerged across the cases is a clearer picture of what underwriters now demand before they will cover string business, and what a claim file must contain for it to be paid.

How the underwriting market has repositioned

The credit insurance market has followed the same path as commodity banks after 2020. Some smaller insurers have stepped back from commodity trading entirely, particularly for counterparties booked out of Singapore, Hong Kong and Dubai. Larger carriers have concentrated on the major trading houses, whose earnings come from physical margin as well as financing. Lawyers in the space describe a market that still accepts string business in principle but views it as higher risk and prices it accordingly.

Insurers that remain active have rewritten their wordings. One approach discussed by ICISA is to require the policyholder to show an intention to take possession of the goods from the outset. Proving the absence of intent is hard for an insurer, but indicators of no intent are measurable, such as a cargo changing hands many times within days, or a policyholder with no logistical capacity to receive the goods.

Disclosure is now the pricing lever, not the risk

The single most consistent lesson from the disputes is that disclosure at placement protects the trader. Where cargoes change hands instantly and participants use a document bypass system, so that originals go directly to the end of the chain, lawyers advise telling the underwriter so at the outset. That removes the argument, raised in several cases, that the policyholder misrepresented its business or that the transactions were fictitious.

Full disclosure raises premium. Some traders have historically understated their string activity to secure cheaper cover, then discovered at claim stage that the policy did not respond. A higher premium on an accurate wording is a cost of doing business. A cheaper premium on a misdescribed wording is closer to no cover at all.

Rhodium v FCIA and the shift from possession to evidence

One less publicised US case shows where the argument is moving. The liquidator of Rhodium International Trading USA, the US arm of Singapore-based Rhodium Resources (since renamed Antanium Resources), sued FCIA, the credit and political risk division of Great American Insurance Company, in an Atlanta court in early 2023. Rhodium had run into difficulty in August 2020 after buyer defaults, loss of insurance cover and creditor demands.

Rhodium had lodged eight claims of roughly USD 20 million in mid-2021 after non-payment by several trading house buyers. Four were later withdrawn, leaving just under USD 12 million in dispute, with the remaining trades funded by White Oak Trade Finance. FCIA denied the claims and argued in a 2024 filing that the trades were paper-only financial activity outside policy scope. Rhodium maintained it had always disclosed its back-to-back model and its use of copy bills of lading.

The notable development came in December 2025. FCIA accepted in a filing that goods can legitimately be traded back-to-back in a string or circle, and that a document bypass arrangement can mean no participant ever holds an original bill of lading. Its objection narrowed to a different point. In its view, nothing in the record tied the shipments to Rhodium, for example no evidence that the upstream seller in one soybean trade had any right to the cargo it sold. The parties settled confidentially in July 2026, so the court never ruled on any of these issues, and nothing here suggests a finding against either side.

The significance for the market is the direction of travel. The debate is moving away from whether a string trader must hold the goods or the originals, and toward whether the trader can prove its link in the chain to a real, identified cargo. Courts have treated structured trades as genuine trades. A chain with no vessel and no goods, only documents and money, is not.

Practical structuring for traders running string business

What this means for lenders and receivables financiers

Funders that advance against insured receivables have absorbed part of the fallout. A policy assigned to a lender is only as good as the policyholder's disclosure and evidence. Lenders active in commodity receivables now test wordings line by line, require sight of the proposal form, verify cargo independently through vessel tracking and inspection data, and set limits on how many times a cargo may change hands before it becomes ineligible. Some pair credit insurance with other forms of credit enhancement or require the end buyer to pay under a documentary letter of credit, which shifts the payment risk to a bank rather than relying on indemnity after default.

For traders, this tightening means that a well-documented, honestly insured string book is now a competitive advantage. It is easier to finance, cheaper to finance once the lender is comfortable, and far more likely to recover value when a buyer defaults.

How Financely approaches commodity trade finance

Financely is a debt advisory and arranging firm. On structured commodity finance mandates, we review the trade flow, the documentary chain, the insurance wording and the counterparty profile before approaching funders from our network of more than 12,700 verified lenders. Where back-to-back or string trades are part of the model, we position the disclosure and the evidence file so that lenders and insurers price the real risk, rather than discovering it later.

Frequently asked questions

Are string trades legal?

Yes. Nothing in the law prevents a sequence of sales between parties that never take physical possession of the goods, and courts have recognised structured trades as genuine trades. The problem arises when there is no real cargo, or when a participant cannot show its link to one.

Will trade credit insurance cover a string trade?

It can, if the policy wording covers the model and the business was accurately disclosed at placement. Policies written on the assumption of physical control, or placed on an incomplete description of the business, are the ones that have produced disputes.

What is a document bypass arrangement?

It is an agreement among participants in a chain that the original bills of lading travel directly to the final buyer, rather than passing through each intermediary. It is used in limited circumstances for certain commodities and should be disclosed to the insurer and the lender.

Does disclosing string activity make insurance more expensive?

Usually yes, because underwriters view structured trading as higher risk. The alternative, cheaper cover on an inaccurate description, risks a declined claim and allegations of misrepresentation.

Can a receivables lender rely on the insurance alone?

Lenders increasingly do not. Claims take time to assess and pay, and cover depends on the policyholder's disclosure. Most lenders now combine insurance with independent cargo verification, eligibility limits and, where possible, bank payment instruments.
