Banker's Acceptance: a Worked Example

The bank signs the bill, and a promise to pay later becomes cash.

BY MICHAEL SHANG · SIXTEEN YEARS IN COMMERCIAL BANKING · UPDATED

// THE SHORT ANSWER

For an exporter selling on credit terms, a banker's acceptance is the point at which a promise to pay in four months becomes something it can sell today. The exporter draws a bill of exchange; a bank signs it as acceptor and so takes the debt on in its own name, payable on a fixed date. Because the debtor is now a bank, the bill can be discounted at a price set by the bank's credit rather than the buyer's. For the accepting bank it is a debt it must meet at maturity, recovered from whoever it accepted for: its customer, or the issuing bank that asked it to.

// 01 — WHAT A BANK TAKES ON WHEN IT SIGNS

A bill of exchange is an unconditional written order from one party, the drawer, telling another, the drawee, to pay a sum on demand or at a fixed or determinable future date. Until the drawee agrees, the drawee is not bound by it; the drawer, and anyone who has indorsed the bill, are. Acceptance is that agreement, written on the bill and signed by the drawee. The three markets share one code for it, the UK's Bills of Exchange Act 1882, followed closely by New Zealand's Bills of Exchange Act 1908 and Australia's Bills of Exchange Act 1909. Each defines acceptance and makes the acceptor liable to pay the bill on the terms it accepted.

When the drawee is a bank, the bill carries the bank's credit, and that is the purpose. A buyer the exporter barely knows has been replaced by a bank the market can price. The bank holds a claim for the face value at maturity on whoever it accepted for, the importer or the issuing bank that nominated it, and books that as an exposure from the day it signs, because it must pay the holder whether or not that party pays it.

// 02 — HOW THE BILL IS MADE AND DISCOUNTED

In trade, the acceptance usually comes out of a usance letter of credit made available by acceptance. The exporter ships and presents its documents with a draft drawn at, say, 120 days after sight. The ICC's rules for documentary credits, UCP 600, do not allow a credit to be made available by a draft drawn on the applicant, so the drawee is a bank. If the documents comply, the nominated bank accepts (if it declines, the issuing bank must honour instead), and the rules authorise a nominated bank that has accepted a draft to prepay or buy it.

Face value what the acceptor pays at maturity
Discount face value × discount rate × days to run ÷ day basis
Commission face value × acceptance rate × days to run ÷ day basis
Cash to the holder face value − discount − commission

Two prices sit in those lines. The acceptance commission is the bank's fee for lending its name. The discount is the buyer of the bill's return for waiting. Because both are taken off the face value rather than added to the cash, the effective rate on the money received is a little higher than the quoted rates. The day basis follows the currency's money-market convention; the example uses 360 days, the usual basis for US-dollar paper.

// 03 — THE EXAMPLE

A wine exporter, constructed for this page like every figure in it, sells US$800,000 of wine to an importer under a credit available by acceptance of a draft at 120 days after sight, with the exporter's own bank nominated. The documents comply. The nominated bank accepts the draft and offers to discount it at 5.4% a year, with an acceptance commission of 0.75% a year. Both rates belong to the example and are not a market norm.

Face value of the accepted bill 800,000
Discount 800,000 × 5.4% × 120 ÷ 360 = 14,400
Commission 800,000 × 0.75% × 120 ÷ 360 = 2,000
Cash to the exporter today 783,600
Effective cost 16,400 ÷ 783,600 × 360 ÷ 120 = 6.28% a year

The exporter has cash at shipment and no foreign debtor to chase. On day 120 the issuing bank reimburses the nominated bank and debits the importer under its facility. The nominated bank, having bought its own acceptance, has carried the issuing bank's risk for four months and been paid for it.

Change one fact. The credit is available by deferred payment instead: the bank promises to pay on day 120, but no bill is drawn. The exporter can still be paid early, since UCP 600 lets a nominated bank prepay its own deferred payment undertaking, but the paper changes. There is no negotiable instrument. A third party can still buy the right to be paid, but by assignment, which passes the claim subject to defences, and bill-of-exchange law, with its protection for a holder in due course, has nothing to attach to.

// 04 — HOW IT DIFFERS FROM A TRADE ACCEPTANCE

The nearest neighbour is a bill accepted by the buyer itself, the trade acceptance that documents against acceptance produces under a documentary collection. The paper looks the same and the same Act governs it. The difference is the signature. A trade acceptance is worth what the importer is worth, and an exporter that discounts one is borrowing against its buyer's credit, usually with recourse to itself if the buyer does not pay. A banker's acceptance moves that credit to a bank.

Recourse does not vanish. Unless the drawer stipulates otherwise on the bill, it stays liable if the acceptor does not pay at maturity, provided it is given due notice of dishonour, so an exporter that sells an accepted bill to a third party has not wholly left the chain. A bank that discounts its own acceptance carries the risk of its reimbursing bank itself.

In Australia the instrument had a second life as domestic funding. Under a bill facility the borrower, not a trading partner, drew bills that its bank accepted and discounted, and banks lent to businesses that way for a long time. The habit survives in names. Australian business loans are commonly priced off BBSY, the bid rate set five basis points above BBSW, and BBSW is calculated from trading in prime banks' short-term paper, now mostly certificates of deposit with bank-accepted bills the balance. New Zealand's equivalent is BKBM, the bank bill benchmark rate, set each business morning from the market in bank bills.

// 05 — WHERE IT DECIDES A FILE

For the exporter's banker, an accepted bill turns a receivable owed from abroad into a claim on a bank, which changes what can be lent against it and at what price. A credit paper that relies on discounting should say who the acceptor is, whether the credit is available by acceptance or by deferred payment, and what recourse the discounting bank keeps against the exporter.

For the importer's banker, the acceptance is a promise to the market that does not wait for the customer. The limit is used from acceptance to maturity, the goods have usually been released against the documents long before, and the bank's protection for those four months is whatever its facility, its security and any trust receipt give it. The credit decision is about the importer's cash in four months' time, not about the wine.

// QUESTIONS PEOPLE ASK

What is the difference between a banker's acceptance and a letter of credit?
A letter of credit is a bank's conditional promise: it will pay, or accept a bill, if complying documents are presented. A banker's acceptance is what that promise produces once the documents have been accepted: a bill of exchange the bank has signed and must pay on the maturity date. The first is a commitment that depends on documents; the second is a debt of the bank that can be held to maturity or sold to an investor or another bank.
Who pays the discount on a banker's acceptance?
Whoever sells the bill before it matures. The cash received is the face value less the discount for the time left to run, so in trade it is usually the exporter. The sale contract and the credit can shift it: some credits provide for the exporter to be paid at sight while the importer bears the discount and acceptance charges, so the importer keeps its credit period.
Is a banker's acceptance a loan?
Not in form, but close to one in substance. The accepting bank has an exposure to its customer from the day it signs, even though no money leaves the bank until maturity unless it also discounts the bill. The customer owes the bank the face value on the maturity date. If the bank discounts its own acceptance, it has advanced the face value less the discount, and the position works like a short loan repaid on a fixed day.
Are banker's acceptances still used?
Yes, chiefly in trade. They arise under usance credits made available by acceptance and under importers' acceptance facilities, and they remain the way an exporter on credit terms can be paid early against a bank's name. Their role as general funding paper is narrower than it was. In Australia and New Zealand the bank bill survives most visibly in the short-term benchmarks many business loans are priced from: BBSW and its bid rate BBSY in Australia, BKBM in New Zealand.
