Core Trade Finance Structures Explained

In physical commodities, lenders rarely finance a company. They finance a controlled transaction or a controlled pool of assets. That is the difference between generic lending and trade finance.

The four structures below show up repeatedly because they map cleanly to how commodities move: purchase, storage, production, export, and collection. The structures are not interchangeable. Each one has a different collateral base, a different control stack, and a different failure mode.

Covered In This Guide

  • Borrowing Base Facilities
  • Inventory Financing
  • Pre-Export Finance
  • Offtake Prepayment Financing

Why This Matters

  • These structures drive advance rates and pricing
  • They determine which lenders can participate
  • They define reporting and monitoring burden
  • They decide whether funding is repeatable or one-off

The Control Stack That Makes Trade Finance Work

Trade finance is mostly controls. Collateral is necessary but not sufficient. Lenders want legal rights plus operational control points that prevent cash leakage.

Common Controls

  • Title control and pledge mechanics
  • Independent inspections and quantity/quality verification
  • Controlled accounts and assignment of proceeds
  • Release mechanisms linked to repayment conditions
  • Insurance, loss payee clauses, and sanctioned counterparties screening

The CMA Is Often The Backbone

A collateral manager and a Collateral Management Agreement are frequently used to make inventory and borrowing base facilities financeable. If you want the detailed mechanics, see our guide on Collateral Management Agreements in Trade Finance.

1) Borrowing Base Facilities

A borrowing base facility is a revolving credit line where availability is formula-driven. The lender does not lend against your “plan”. The lender lends against eligible collateral pools at defined advance rates, less reserves.

Component What It Means Why Lenders Care
Eligible Inventory Goods that meet eligibility rules (location, title, quality, insured, verified) Inventory is financeable only when it is controllable
Eligible Receivables Invoices owed by approved buyers within defined tenor limits Collection predictability drives pricing and leverage
Advance Rates Percentages applied to eligible collateral to determine availability Advance rates reflect volatility, liquidity, and control quality
Reserves Deductions for concentration, disputes, slow pay, seasonality, or jurisdiction risk Reserves protect the lender from data errors and stress cases
Borrowing Base Certificate Recurring report showing calculations and collateral schedule It is the trigger for draws, holds, and margin calls

What Usually Breaks Borrowing Base Facilities

  • Weak title chain or unclear ownership in transit
  • No independent verification of stock and movements
  • Buyer concentrations that blow through eligibility caps
  • Poor reporting cadence or inconsistent data tapes
  • Commodities stored in facilities the lender cannot control

Borrowing base design is technical. Eligibility rules, reserves, triggers, and monitoring should be written like a control manual, not like marketing copy. Our structuring approach is outlined on Trade Finance Structuring and Borrowing Base Design.

2) Inventory Financing

Inventory financing is asset-backed funding secured specifically by physical goods. This is the structure that funds stock on the ground, in tanks, or in bonded storage.

Collateral Package

  • Pledge over inventory and proceeds
  • Warehouse receipts or tank receipts
  • Insurance assignment and loss payee endorsements
  • Inspection regimes and release protocols
  • Collateral manager oversight in many cases

Lender Comfort Comes From Control

Inventory is not “safe” because it exists. It is financeable when the lender can enforce title, verify quantity and quality, and block release unless repayment conditions are satisfied.

Inventory Financing vs Borrowing Base

Inventory financing is often transactional and tightly linked to a defined stock parcel. Borrowing base facilities are programmatic, revolving, and cover larger pools across time. In practice, inventory financing frequently sits inside a broader borrowing base structure.

Common Failure Modes

  • Storage sites that do not allow enforceable access or control
  • Commingled goods without segregation and clear identification
  • Inadequate insurance or exclusions that matter in real claims
  • Operational leakage: releases not aligned to controlled accounts

3) Pre-Export Finance

Pre-export finance funds production ahead of export and sale. It is common in mining, agriculture, energy, and industrial supply chains where the producer has predictable output and credible buyers.

Typical Repayment Logic

  • Facility funds working capital or production costs
  • Production is sold under export/offtake contracts
  • Export proceeds are assigned to controlled accounts
  • Debt amortizes from each shipment on a predefined schedule

What Lenders Actually Underwrite

  • Production capacity and ramp profile
  • Cost curve and margin under downside pricing
  • Operational risk and track record
  • Buyer enforceability and payment certainty
  • Jurisdiction and export logistics reliability

What Usually Breaks Pre-Export Finance

  • Overstated production assumptions and weak contingency planning
  • Contracts that look strong but do not bind cash flows
  • Export bottlenecks and logistics gaps that delay shipments
  • Proceeds not fully captured due to account control failures

4) Offtake Prepayment Financing

Offtake prepayment financing is when a buyer prepays for future deliveries. In many cases the buyer is the conduit and a bank or private credit lender funds the prepayment behind the scenes because the buyer’s credit is stronger than the producer’s.

Why Offtake Prepayment Is Powerful

  • It ties funding to a contracted sales channel
  • Amortization can be matched to deliveries
  • Buyer involvement reduces some performance risk
  • It can fund capex or working capital depending on terms

What Lenders Still Require

  • Delivery controls and performance remedies
  • Pricing mechanics that survive volatility
  • Clear events of default and step-in rights
  • Account control and proceeds capture
  • Sanctions, compliance, and counterparty diligence

Common Failure Modes

  • Prepayment used for unrelated purposes without monitoring
  • Contracts lacking enforceable delivery and repayment mechanisms
  • Insufficient security package when performance deteriorates

How These Four Structures Combine Into Senior, Mezzanine, and Junior Tranches

Many commodity financings are layered. Senior lenders fund the most controlled, most liquid part of the collateral base. Mezzanine and junior tranches bridge gaps created by volatility, concentration limits, or weaker counterparties.

Senior Tranche

Typically supported by controlled inventory, eligible receivables, tight covenants, and strong account control. Lowest pricing. Highest control burden.

Mezzanine and Junior Tranches

Used to increase leverage, fund timing gaps, or support growth. Pricing rises as control weakens or volatility increases.

The practical point: the better your collateral and controls, the more of your capital stack can sit in the senior tranche. That is where cost of capital improves.
