Standby Letter of Credit in Paraguay: Securing Export Transactions
Partager
You sell five hundred thousand dollars worth of goods to a buyer on the other side of the world whom you've never met. Delivery is in sixty days, payment afterward. What happens if they don't pay? The goods are gone, they've reached their destination, and your recourse is to initiate legal proceedings in a country whose language you don't speak, under laws you don't understand.
The problem is symmetrical. If you pay in advance, what happens if the supplier never delivers?
International trade relies on trust between two distant parties that has no real basis. The stand-by letter of credit, often referred to by its English acronym SBLC, is the instrument that replaces this trust with a bank commitment. A bank promises to pay the beneficiary if its client defaults on their obligations. It is not intended to be used; it is a safety net, not a method of payment.
The Mechanism
A stand-by letter of credit is an irrevocable commitment by a bank to pay a specified sum to the beneficiary if the applicant fails to meet their obligations. It adheres to international rules published by the International Chamber of Commerce, primarily the ISP98 practices, sometimes the rules applicable to documentary credits.
The process involves four steps. The applicant requests their bank to issue the guarantee in favor of their counterparty. The bank assesses its credit risk, because in case of a call, it will have to pay first and then seek reimbursement. If it accepts, it issues the document and transmits it to the beneficiary's bank via the global interbank network, in a standardized format recognized everywhere. The beneficiary is then protected.
In the normal scenario, nothing happens: obligations are met, and the guarantee expires unused. Otherwise, the beneficiary presents the required documents, the bank pays, and then seeks reimbursement from its client.
Not to be Confused with Documentary Credit
The distinction is simple and often misunderstood. A documentary credit is a means of payment: the bank pays the seller as soon as conforming shipping documents are presented, and it is used for each transaction. A stand-by letter of credit is a guarantee: it only comes into play in case of default.
One is the method of settlement, the other is the insurance. The latter is lighter and less expensive; the former offers maximum security to the seller at the cost of formidable documentary formality, where the slightest irregularity blocks payment.
Main Uses
| Type | What it Guarantees |
|---|---|
| Payment Guarantee | Payment of an invoice. This is the most common use. The exporter is assured of being paid even if the buyer defaults. |
| Performance Guarantee | The completion of a service or delivery. The client receives compensation if the service provider fails to perform. Common in service contracts and supply agreements. |
| Advance Payment Guarantee | The reimbursement of an advance payment. If you pay 30% when ordering a machine, this guarantee protects you against non-delivery. |
| Rental Guarantee | Payment of rent. It replaces a cash security deposit, freeing up working capital. |
| Bid Bond/Tender Guarantee | The seriousness of an offer in a tender. Required in most public procurements, it is called if the successful bidder refuses to contract. |
Obtaining a Guarantee in Paraguay

Several local banks have foreign trade departments capable of issuing this type of instrument. They are mainly distinguished by two criteria that must be examined before choosing.
The first is the correspondent network. A guarantee is only as good as its issuer. Subsidiaries of regional or international groups have dense networks and readily recognized guarantees. Purely local institutions, less known abroad, sometimes require the beneficiary to request confirmation, which increases the cost of the operation.
The second is sectoral specialization. Some Paraguayan banks are intimately familiar with agricultural exports, their incoterms, deadlines, and quality disputes. If your activity falls within this domain, this familiarity is often more valuable than a broader network.
Consult two or three institutions and compare three elements: the commission rate, the level of collateral required, and the list of correspondent banks in your partners' countries.
The Process
The process begins with an application for issuance to the foreign trade department, specifying the type of guarantee, its amount, currency, beneficiary, duration, and especially the call conditions, i.e., the documents the beneficiary will need to produce.
Next comes the credit analysis, which is the decisive step. The bank examines your accounts for the past two or three fiscal years, your transaction history, your international trade experience, and determines the collateral it requires.
Then, the issuance and transmission to the correspondent, and finally the notification to the beneficiary by their own bank, which verifies its authenticity.
Allow one to three weeks in total, longer for a first application, less for an established client with up-to-date accounts.
What it Really Costs
Three items, only one of which is truly significant.
The issuance commission typically ranges from 1 to 3% per annum of the guaranteed amount, calculated pro rata for the duration. It decreases with the quality of your application and the importance of the sums involved.
Interbank transmission fees are fixed and negligible, on the order of a few tens to a few hundreds of dollars, plus similar fees for each subsequent modification.
The confirmation commission, if the beneficiary requires their own bank to also commit, adds half a point to two annual points. It is generally not necessary when the issuer is an internationally recognized bank.
The determining factor remains: the collateral. The bank may require between 10 and 100% of the guaranteed amount to be blocked, in cash or other forms of security. At 100%, the instrument loses all interest, since you tie up the entire sum. The real cost of a guarantee is therefore not its commission, but the return you forgo on the blocked funds.
As a rough estimate: for one hundred thousand dollars guaranteed for one year, expect about fifteen hundred dollars in commission and fees, plus the cost of immobilizing the collateral. The first amount is negligible compared to the risk covered; the second deserves negotiation.
Five Practical Situations

You are exporting. You ship three hundred thousand dollars worth of goods to a European importer, payable thirty days after receipt. Demand a payment guarantee from them issued by their bank. If they don't pay, you present the unpaid invoice and proof of delivery, and the bank pays. This is classic practice, and it should be systematic with a new client.
You are importing with an advance payment. A foreign supplier demands half the price upon order. In return, request an advance payment guarantee. If delivery does not occur, you recover your payment.
You are selling services abroad. An important client requires a performance guarantee representing about one-tenth of the contract value. This is restrictive, but it is also a commercial argument: for a small Paraguayan entity lacking international references, this guarantee replaces the reputation you don't yet have.
You are renting offices. The landlord requests six months' rent as a deposit. This money sits idle. A rental guarantee costs a few hundred dollars per year and only ties up a fraction of the amount, with the rest remaining available. This is a favorable trade-off as soon as the deposit represents a significant sum.
You are bidding on a public contract. Paraguayan tenders require a bid bond and then a performance guarantee, and accept bank guarantees in lieu of a deposit. For a small business, this makes access to public contracts materially possible, a topic covered in our MIPYME regime guide.
Other Instruments
| Instrument | When to Prefer It |
|---|---|
| Documentary Credit | For shipments of goods with a new partner, when the seller wants maximum payment security. More expensive and much more formal: a minor irregularity is enough to block payment. |
| Demand Guarantee | Functionally equivalent to a stand-by letter, derived from the continental legal tradition and preferred in Europe and the Middle East. More a difference in terminology and rules than in substance. |
| Export Credit Insurance | When you have many buyers rather than an exceptional transaction. A single policy covers the entire portfolio, without collateral, and also covers political risk. In return, compensation is partial, and the availability of these contracts in Paraguay requires verification. |
| Security Deposit | For small amounts, when simplicity is key. Two drawbacks: full immobilization of funds and counterparty risk if the depositary defaults. |
| Escrow | For intermediate transactions, from a few thousands to a few tens of thousands of dollars, where the fixed cost of a bank guarantee would be disproportionate. |
Tax Treatment
| Element | Treatment |
|---|---|
| Bank commission | Deductible expense from taxable income. Bank commissions are subject to the reduced 5% VAT rate, allowing for deduction, as detailed in our guide to Paraguayan VAT. |
| Blocked collateral | No tax implications: the funds remain your property. Any interest earned on this deposit is taxable as local source income. |
| Guaranteed receipts | The guarantee does not change the source of income. An export from Paraguay remains of Paraguayan source, taxable at 10%, whether the transaction is guaranteed or not. However, the export of goods and services is zero-rated for VAT. |
| Call of the guarantee | You must reimburse the bank. The treatment of the disbursement depends on the circumstances of the default and should be arbitrated with your accountant. Beyond taxation, a call constitutes a serious event: it signals a default to your bank and results in reduced credit lines and damage to your reputation. |
Six Mistakes to Avoid
- Accepting a guarantee from an unfamiliar bank. A guarantee is only as good as its issuer. Check its rating by an international agency, and demand confirmation by a top-tier institution if the issuer is obscure or located in a risky country. This is where hasty exporters often go wrong.
- Neglecting the drafting of call conditions. The document is a legal act where every term matters. Ambiguous conditions allow the bank to refuse payment for documentary non-compliance, even if the default is proven. Have the draft reviewed by a lawyer familiar with these instruments: a few hundred to a few thousand dollars to secure a guarantee worth a hundred times more.
- Using it for small amounts. The fixed fees make the instrument disproportionate below several tens of thousands of dollars. Escrow, card payment, or partial wire transfer are more suitable.
- Miscalculating the duration. A guarantee that expires before the default occurs is useless. Allow a margin of one to two months beyond the contractual due date, and consider an automatic renewal clause with a non-renewal notice.
- Mistaking it for general insurance. It covers contractual default, nothing else. Neither loss of goods in transit, which falls under transport insurance, nor political risk, nor currency risk, which requires forward cover. It is one tool among others in a coherent risk management strategy.
- Accepting the proposed collateral without discussion. This is the most expensive item, and it is negotiable. Four levers: build a banking history over one or two years, which automatically lowers the requirement; propose alternative security such as a mortgage; seek competitive bids from two or three institutions, whose policies differ significantly; and, if you have a securities portfolio, consider a loan against that portfolio to constitute the collateral without selling assets, carefully weighing the cost of this loan.
Conclusion

The stand-by letter of credit solves a simple problem: doing business with someone whose word you can't trust. It replaces unfounded trust with a bank's commitment, according to international rules that all institutions worldwide apply in the same way.
The calculation is rarely debatable beyond a few tens of thousands of dollars: a few thousand dollars in commission versus the risk of losing an entire cargo. What is negotiable is not this cost, but the collateral, and that's where the main issue lies.
One last point deserves emphasis, because it is counter-intuitive. For a small Paraguayan company entering foreign markets without references, a bank guarantee doesn't just protect them: it helps them to be taken seriously. It proves that a financial institution has examined their accounts and agreed to commit on their behalf. It is a certificate of solvency, and for a newcomer, it can sometimes secure the contract.
