Bill of Exchange · trade-finance
A Bill of Exchange is a negotiable instrument issued by the drawer, entrusting the drawee to pay a determined sum unconditionally to the payee or holder upon sight or on a specified date. In the field of overseas engineering finance, a bill of exchange is not only a payment instrument but also a three-in-one carrier of credit instrument, financing instrument, and risk mitigation instrument.
From a legal perspective, bills of exchange are governed by three major systems: the UK Bills of Exchange Act 1882, the US Uniform Commercial Code (UCC Article 3), and the Geneva Convention Providing a Uniform Law for Bills of Exchange and Promissory Notes. China enacted its Negotiable Instruments Law in 1995, amended in 2004, adopting the Geneva law system framework with certain adjustments. In cross-border engineering, the governing law clause of a bill of exchange often determines the success or failure of the right of recourse.
In overseas engineering practice, bills of exchange typically appear in the following scenarios:
The core difference between bills of exchange and Letters of Credit (L/C) and Guarantees is: a bill of exchange is an abstract instrument — once accepted, the payment obligation is independent of the underlying contract; while L/Cs and guarantees, although also independent, typically involve bank credit intervention. Bills of exchange can be commercial credit (commercial acceptance bills) or bank credit (bank acceptance bills), with the latter being more widely accepted in cross-border engineering.
Key characteristics:
| Element | Specific Content | Typical Parameters in Overseas Engineering | Notes |
|---|---|---|---|
| **Amount** | Face value of the bill | USD 500,000~50,000,000 | Currency must be specified; avoid mixing multiple currencies |
| **Tenor** | At sight / after date / after sight | 30/60/90/180 days | Beyond 180 days requires consideration of discount costs |
| **Rates** | Acceptance fee, discount rate, handling fee | Acceptance fee 0.1%~0.5%; discount rate SOFR+2%~5% | Bank acceptance rates lower than commercial acceptance |
| **Applicable Scenarios** | Engineering payment, equipment procurement, subcontractor settlement | Mainly Middle East, Africa, Southeast Asia projects | Less used in European and American projects |
| **Drawer** | Party obligated to pay | Employer, main contractor, purchaser | Drawer's credit rating must be assessed |
| **Drawee** | Actual paying party | Bank or enterprise | Bank acceptance superior to commercial acceptance |
| **Payee** | Rights holder | Contractor, supplier, subcontractor | Can be designated or transferred by endorsement |
| **Acceptance** | Drawee's promise to pay | Bank acceptance / commercial acceptance | Irrevocable after acceptance |

Scenario Comparison:
| Scenario | Recommended Tenor | Recommended Acceptance Method | Reason |
|---|---|---|---|
| Employer pays progress payments | 90~180 days | Bank acceptance | Employer credit varies |
| Subcontractor settlement | 30~60 days | Commercial acceptance | Small amounts, high frequency |
| Equipment procurement | 60~90 days | Bank acceptance | Suppliers require high credit |
| Advance payment substitute | 180~360 days | Bank acceptance | Must cover entire procurement cycle |
| Retention release | At sight | Bank acceptance | Amount determined, timing clear |
Who initiates: Typically initiated by the paying party (employer/main contractor), but in practice often the receiving party (contractor/supplier) requires bill of exchange payment in the contract and prompts the paying party to issue the bill upon reaching payment milestones.

Key Operational Points:
Background: CCCC constructed the Kenya Mombasa-Nairobi Standard Gauge Railway, with a contract value of approximately USD 3.8 billion. The employer was Kenya Railways Corporation, with funding from the Export-Import Bank of China concessional loans.
Bill Application: The project adopted a "milestone payment + bill of exchange" model. After confirming each milestone, the employer issued 180-day time bank acceptance bills to CCCC, accepted by Kenya Commercial Bank. CCCC discounted the bills to Bank of China Nairobi Branch at a discount rate of SOFR+2.8%, rapidly recovering funds.
Specific Figures:
Result: The project was completed on schedule, and all bills were honored. However, during this period, the Kenyan Shilling depreciated approximately 8% against the US Dollar. Since the bills were denominated in US Dollars, the exchange rate risk was borne by the employer, and CCCC suffered no losses.
Experience: Insisting on USD denomination, bank acceptance, and clear recourse clauses were the keys to success.
Background: PowerChina constructed the Pakistan Karot Hydropower Project, with a contract value of approximately USD 1.7 billion. The employer was a Pakistani private power company, with funding from the International Finance Corporation (IFC) under the World Bank and the Export-Import Bank of China.
Bill Application: Since the employer was a private enterprise with insufficient credit rating, the project adopted a "bank guarantee + commercial acceptance bill" combination. The commercial acceptance bills issued by the employer were guaranteed by Habib Bank Pakistan (Aval), and PowerChina then discounted the bills to ICBC Karachi Branch.
Specific Figures:
Risk Event: In 2022, Pakistan's foreign exchange reserves were tight, and the employer was temporarily unable to honor payment on time. PowerChina, based on the bill's recourse clause, sought recourse against the guaranteeing bank Habib Bank, ultimately recovering all funds plus overdue interest (SOFR+4%) after 45 days of delay.
Experience: Commercial acceptance bills must have bank guarantee (Aval), and overdue interest and recourse procedures must be clearly specified in the contract.
Background: CRCC constructed the Saudi Arabia Mecca Light Rail Project, with a contract value of approximately USD 1.8 billion. The employer was the Saudi Ministry of Municipal and Rural Affairs, with funding from the Saudi government budget.
Bill Application: The project adopted a "sight bill + time bill" combination. Progress payments used sight bills, and retention used 360-day time bills. All bills were accepted by Saudi National Commercial Bank.
Specific Figures:
Challenge: Saudi law requires bill dishonor to be notarized within 15 days, otherwise the right of recourse is lost. Due to unfamiliarity with local law, CRCC once nearly lost its right of recourse because notarization was 3 days late, later resolved through negotiation.
Experience: Cross-border bills require understanding of local negotiable instruments law, especially dishonor notarization deadlines.
| Solution | Credit Basis | Cost | Liquidity | Applicable Scenarios | Risk |
|---|---|---|---|---|---|
| **Bank Acceptance Bill** | Bank credit | Low (0.1%~0.5% acceptance fee + SOFR+1.5%~3% discount) | High | Insufficient employer credit, large payments | Bank risk, country risk |
| **Commercial Acceptance Bill** | Corporate credit | Medium (SOFR+3%~8% discount) | Medium | Main contractor to subcontractor, related-party transactions | Drawer default risk |
| **Letter of Credit (L/C)** | Bank credit | Medium (0.5%~1.5% issuance fee + document handling fee) | High | Equipment procurement, international trade | Document discrepancy risk |
| **Bank Guarantee** | Bank credit | Medium (0.5%~2%/year) | Low | Advance payment, performance, warranty | Claim risk |
| **Cash Payment** | Immediate | None | Highest | Small amounts, urgent | None |
| **Accounts Receivable Factoring** | Corporate credit | High (SOFR+5%~10%) | High | Completed but uncollected | Recourse risk |
| **Forfaiting** | Bank credit | High (SOFR+3%~6%) | Highest | Large amounts, long-term | Without recourse |
Selection Recommendations:
Q1: What is the difference between a bill of exchange and a promissory note?
A: A bill of exchange involves entrusting the drawee to pay, involving three parties: drawer, drawee, and payee; a promissory note is paid by the drawer itself, involving only two parties: drawer and payee. Bills of exchange are more common in overseas engineering because employers typically do not wish to directly assume payment obligations.
Q2: Are bank acceptance bills always safe?
A: Not necessarily. The accepting bank's credit rating and country risk must be assessed. For example, in 2022, Sri Lankan bank acceptance bills could not be honored due to national bankruptcy. Banks with international ratings of BBB or above are recommended.
Q3: What to do if a bill is dishonored at maturity?
A: Immediately obtain a Protest, and within the statutory time limit (typically 3~15 days) send notice of dishonor to all prior parties, then choose negotiation or litigation. The limitation period for recourse is typically 6 months to 2 years.
Q4: Can a bill be partially discounted?
A: Yes. Some banks support partial discounting, but fees are charged on the full amount, making the actual cost higher. Full discounting or splitting issuance is recommended.
Q5: Do cross-border bills require notarization?
A: Depends on destination law. Generally, notarization is required upon dishonor, not for normal payment. However, some countries (such as in the Middle East) require the bill itself to be notarized or consular-authenticated.
Q6: What to do if a bill is lost?
A: Immediately report loss and stop payment to the paying bank, and apply to the court for public notice. The public notice period is typically 60~90 days, after which a judgment of exclusion may be applied for. The process is complex; safekeeping is recommended.
Q7: Can a bill be transferred to a third party?
A: Yes, through endorsement. However, note: if the bill states "not transferable," it cannot be transferred; if it is a blank endorsement, any holder can assert rights, posing greater risk.
Q8: Is a longer bill tenor better?
A: No. The longer the tenor, the higher the discount cost and greater the exchange rate risk. Tenor should match project cash flow, generally not exceeding 180 days.
Q9: How to enhance credit for commercial acceptance bills?
A: Can require bank guarantee (Aval), parent company guarantee, asset mortgage, or third-party guarantee. After credit enhancement, the discount rate can be reduced by 1%~3%.
Q10: Can bills of exchange and guarantees be used simultaneously?
A: Yes. Common combination: advance payment with guarantee, progress payments with bills, retention with guarantee. Choose the most appropriate tool based on risk characteristics.
Q11: Does bill discounting affect the relationship with the employer?
A: Usually not, because discounting is the holder's right. However, if the bank seeks recourse against the employer after discounting, it may affect the relationship. It is recommended to explicitly permit discounting in the contract.
Q12: How to assess the credit risk of a bill?
A: Assess the drawer's credit rating, accepting bank's rating, country risk, industry risk, and tenor. S&P, Moody's, and Fitch ratings can be used as references.
Q13: Are bills of exchange stipulated in FIDIC contracts?
A: FIDIC Red Book and Yellow Book do not directly stipulate bills of exchange, but Clause 14 payment terms allow parties to agree on payment methods. Bills of exchange can serve as payment instruments but do not change FIDIC's payment obligations.
Q14: How is bill interest calculated?
A: Typically calculated on actual days/360 basis, with the rate being SOFR+spread. Overdue interest is higher, typically SOFR+2%~4%. Must be specified in the contract.
Q15: Can a bill be cashed early?
A: Yes, through discounting. However, discount interest must be paid, and the actual amount received is less than the face value. The discount rate depends on the acceptor's credit and market rates.
