银行履约保函（Bank Guarantee）：是承包商通过银行向业主提供的保证认真履行合同的一种经济担保。世界银行贷款项目一般规定，银行履约保函金额为合同总价的10%。
银行履约保函分为两种形式：
1、无条件（Unconditional 或 on Demand）银行保函；银行见票即付，不需业主提供任何证据。业主在任何时候提出声明，认为承包商违约，而且提出的索赔日期和金额在保函有效期的限额之内， 银行即无条件履行保证，进行支付，承包商不能要求银行止付。当然业主也要承担由此行动引起的争端、仲裁或法律程序裁决的法律后果。对银行而言，他们愿意承担这种保函，既不承担风险，又不卷入合同双方的争端。
2、有条件（Conditional）银行保函。
银行在支付之前，业主必须提出理由，指出承包商执行合同失败、不能履行其业务或违约，并由业主或监理工程师出示证据，提供所受损失的计算数据等。一般来讲，银行不愿意承担这种保函，业主也不喜欢这种保函。
银行保函也是金融翻译领域非常常见的专业翻译文件，涉及金融、法律、工程等领域的知识技能，也非常考验译者的综合能力。

银行在此无条件的、不可撤销的并且没有任何限制条件的保证、同意并且立约作为截止于______________（以下称为“保函期限”）的确定批次货物的金额达US$ _________（_________美元整）的上述款项或货币的首要义务人，但不是主要的担保人，在收到第一次的书面要求时就付款给买方，不加以任何要求、反对、抵消、抗议或异议，亦不向卖方进行追索，即使通知或说明任何的相反意见或异议。
This Guarantee shall not be affected by any change in the constitution of or by any reason of winding up of the SELLER or any merger, amalgamation or absorption of the SELLER with any other company or companies nor shall this Guarantee be prejudiced by any merger, amalgamation or absorption of BUYER Order for supply of imported coal of 50,000 metric ton ± 10% MT on FOB Mother Vessel basis with any company or companies but shall be available for and by the company formed as a result of merger, amalgamation and absorption.
本保函既不因宪法的变更或任何阻碍卖方或并购企业或卖方与其它公司合并等情况而受到影响，也不得由并购企业或买方按母船离岸价（FOB）与其它公司订购数量为50000公吨±10%进口煤等 原因而发生变化，仅限已经并购与合并的公司。
2.
The neglect or forbearance of the BUYER in enforcing any payment of the money intended to be secured hereof, or the giving of time by the BUYER to the SELLER for the payment under the Contract, shall in no way absolve the Bank from its liability hereunder.
如买方疏怠其付款责任、或延迟向卖方支付本合同项下货款，则银行不得免予承担责任。
3.
The demand shall consist only of an original letter issued by BUYER stating that the SELLER has failed to fulfill its obligations under the Contract. Such demand made by the BUYER on the Bank shall be conclusive and binding, notwithstanding any difference or dispute between the BUYER and the SELLER or any difference or dispute pending before any Court, Tribunal, Arbitrator or any other authority. Such demand may be made to the Bank or its branch in __________ Seoul, Korea whereupon the Bank shall immediately make such payment through the branch in ________ _________.

4.
The Bank undertakes not to revoke this Guarantee during the Term, without the previous written consent of the BUYER and further agrees that this Guarantee herein contained shall continue to be enforceable during the period that would be taken by the SELLER for satisfactory performance and fulfillment of its obligations in all respects under the Contract. For this purpose, the Bank shall, extend the term of this Guarantee for further period(s) of six months at a time (“Extended Term(s)”) upon receipt of written request(s) from the SELLER on whose behalf this Guarantee is issued. The Bank covenants and declares that if the SELLER does not renew this Guarantee, at any time for further period(s) of six months at a time (“Extended Term(s)”), not less than thirty (30) days prior to the expiry of the Term or the Extended Term(s) as the case may be, so as to keep the same valid till the discharge by the SELLER of all its obligations under the Contract, then the entire amount under this Guarantee shall become forthwith due and payable upon the expiry of the Term or the Extended Term as the case may be and the Bank shall on its own, without any demand from the BUYER, during the Claim Period, without demur pay the full amount of this Guarantee to the BUYER.
如未获得买方事先书面批准，银行在保函有效期内不得撤回担保，并进一步同意保函在此期间继续有效，以保证卖方完全履行本合同项下义务。鉴于此，银行收到委托开立保函的卖方书面提出要求时将此保函期限延长六个月（延期）。银行立约并声明：如卖方未在有效期内或延期期限截止30（三十）天内提出本保函一次性延长六个月期限，则有效期保留至卖方履行完毕本合同项下义务为止，这种情况下，本保函有效期截止或延期时限截止时本保函项下总费用由银行支付，无需由买方提出付款要求。在提出索赔要求期间，银行向买方支付本保函全额费用，不得提出抗辨。

The Bank agrees that the BUYER, at its option, shall be entitled to enforce this Guarantee against the Bank as a principal debtor, in the first instance without proceeding against the SELLER and notwithstanding any security or other guarantee that the BUYER may have in relation to the SELLER's liabilities under the Contract.
银行同意买方可自行决定其是否实施本保函，以银行作为其主债务人，无论买方是否与卖方本合同项下责任之间存在抵押或担保，第一原则是不向卖方提起诉讼。
Notwithstanding anything to the contrary contained in this Guarantee, the Bank hereby irrevocably and unconditionally waives any and all rights it may now or hereafter have under any agreement or at law or in equity, to assert any claim against or seek subrogation, contribution, indemnification or any other form of reimbursement from the BUYER for any payment made by the Bank under or in connection with this Guarantee.
即便有异议或反对， 本保函下的银行不可撤销无条件的免除现在或今后持有的任何一种权利不论是源于衡平法、普通法或合同，本保函下或相关银行不应具有代位权、补偿权、免除权或其他任何形式的买方求偿权或让买方付款的权利。
