Resource-Based Lending Explained: RBL, PXF and Resource-Backed Loans
How resource-based lending works, from reserve-based lending and pre-export finance to resource-backed sovereign loans, with borrowing base sizing and key risks.
Resource-Based Lending: How Natural Resources Secure and Repay Debt
Resource-based lending is financing where the lender looks to natural resources, rather than the borrower's balance sheet, for security and repayment. The resource might be oil and gas reserves in the ground, metal concentrate leaving a mine, a crop under an export contract or a government's future commodity revenues. What the structures share is that the debt is sized against the value and cash flow of the resource.
For producers, it can raise far more capital than a corporate balance sheet supports. For lenders, it ties repayment to an asset that can be valued, monitored and, if needed, sold. This guide explains the main forms, how a reserve-based facility is sized, what lenders assess and where the risks lie.
What resource-based lending covers
The term is used in two ways. In corporate and project finance, it describes facilities where the borrower's natural resource assets, production or export contracts are the primary source of repayment. In development finance, it often refers to loans made to governments or state-owned companies that are repaid with, or secured on, future resource revenues.
In both cases the credit question is the same. Lenders want confidence in the volume of the resource, the price it will fetch, the cost of producing it, and their ability to capture the proceeds before anyone else.
The main forms of resource-based lending
| Structure | How it works | Typical borrowers |
|---|---|---|
| Reserve-based lending (RBL) | Revolving facility sized against the discounted value of oil and gas reserves, redetermined periodically | Upstream oil and gas producers |
| Pre-export finance (PXF) | Loan repaid from export contracts, with proceeds assigned to lenders through collection accounts | Producers of oil, metals, agricultural commodities |
| Prepayment finance | A trader or offtaker advances funds against future deliveries, often refinanced by banks | Miners, refiners, agricultural exporters |
| Offtake-backed project finance | Non-recourse debt for new capacity, repaid from long-term offtake contracts | Mine and processing developments |
| Sovereign resource-backed loans | Loans to governments or national companies repaid in, or secured on, resource revenues | Resource-rich states and state-owned enterprises |
| Streaming and royalties | Upfront payment for a share of future production or revenue, without conventional debt | Miners and developers |
Our guides to pre-export finance for commodity producers, prepayment finance in commodity trading and offtake agreement financing cover these structures in more depth.
How reserve-based lending is sized
RBL is the most established form of resource-based lending. The facility is a revolving credit line whose size, the borrowing base, follows the value of the borrower's reserves rather than a fixed commitment.
Reserves
Independent reserve report on proved and probable volumes and production profile
Bank price deck
Lenders apply their own conservative forward prices and cost assumptions
Net present value
Projected cash flows discounted, usually at around 10%, by reserve category
Advance rate
Lenders lend a percentage of NPV, tested against coverage ratios
Borrowing base
The maximum the borrower can draw, recalculated at each redetermination
Redetermination usually happens twice a year, with an updated reserve report and price deck. A lower result can require prepayment or additional collateral.
Reserve categories. Proved developed producing reserves carry the most weight. Undeveloped and probable reserves are discounted more heavily or excluded.
Coverage tests. Facilities typically test that the value of reserves over the life of the loan, and over the life of the field, covers outstanding debt by a set margin.
Hedging. Lenders often require a portion of production to be hedged, supporting the cash flows in the borrowing base. For background, see how upstream oil and gas companies finance drilling.
Resource-backed loans to governments
At sovereign level, resource-backed lending has financed infrastructure and budgets across Africa and Latin America. The Natural Resource Governance Institute identified 52 resource-backed loans worth USD 164 billion to 14 countries between 2004 and 2018, most of them oil-backed and the majority provided by Chinese policy banks, with commodity traders the next largest group of lenders. These loans can provide finance where markets are closed, but their terms are often opaque and they can constrain future fiscal flexibility when commodity prices fall.
What lenders assess
Resource quality
Independent reserve or resource reports prepared under recognised standards, such as SPE-PRMS for oil and gas or JORC and NI 43-101 for minerals.
Production and cost
Operating track record, production forecasts, lifting or mining costs, capital expenditure plans and decline rates.
Offtake and proceeds control
Offtake contracts, buyer credit quality, assignment of receivables and collection accounts under lender control.
Jurisdiction and licences
Title to licences, fiscal terms, export rules, currency convertibility and, where relevant, political risk insurance.
Lenders will also complete KYC and sanctions checks on the borrower, its owners and its offtakers, and review environmental and social performance against the standards their institutions apply.
Key risks
Price cycles. Falling commodity prices reduce borrowing bases and coverage at the same time, which can force repayments when borrowers are least able to make them.
Reserve and production risk. Reserves can be revised downward, and production can fall short of forecasts.
Concentration. Single-asset or single-buyer structures leave little room if one element fails.
Jurisdictional change. Changes to fiscal terms, export rules or state participation can alter the economics of the resource.
Transparency. For sovereign borrowers in particular, undisclosed terms and collateral arrangements can create fiscal risk and reputational exposure for lenders.
How Financely helps
Financely is an advisor and arranger, not a lender. We help oil and gas, mining and agricultural producers structure resource-based financing, from reserve-based and pre-export facilities to prepayment and offtake-backed debt. We prepare the credit package and data room and approach banks, trading houses and funds whose appetite fits the resource, jurisdiction and size. See our overview of oil and gas pre-export and borrowing base facilities, or what a project finance advisory engagement delivers.

Frequently asked questions
What is resource-based lending?
Resource-based lending is financing secured on, or repaid from, natural resources such as oil, gas, minerals or agricultural output, rather than primarily on the borrower's balance sheet. It includes reserve-based lending, pre-export and prepayment finance, offtake-backed loans and resource-backed loans to governments.
Is resource-based lending the same as reserve-based lending?
Reserve-based lending is the most common form in oil and gas, where a revolving facility is sized against the value of proved and probable reserves. Resource-based lending is the wider term and also covers export-linked, prepayment and sovereign resource-backed structures.
How is a reserve-based lending facility sized?
Lenders value the reserves using an independent reserve report and their own price deck, discount the cash flows, and lend a percentage of that value. The resulting borrowing base is redetermined, usually twice a year, and can move up or down with prices and production.
Can mining companies use resource-based lending?
Yes, though structures differ from oil and gas. Producing mines more often use pre-export finance, offtake-linked prepayments, streaming or royalty finance and project finance, with reserves reported under codes such as JORC or NI 43-101.
Does Financely lend against resources?
No. Financely is an advisor and arranger, not a lender. It structures resource-based financings, prepares the credit package and approaches banks, trading houses, funds and other lenders on behalf of producers.
