金融百科给出的解释为“泛指从金融机构（国际货币基金组织、银行等）提取借款”。

从渣打银行的一份贷款提款指令中也可知其含义：

为提高对贷款指令的处理效率、防范操作及道德风险，渣打银行（中国）有限公司（以下均称“渣打银行”或“银行”）在企业和金融机构客户提交贷款提款指令、提款支持性文件、循环贷款申请、还款指令、提前还款指令方面有如下变动及安排。该变动将于2015年1月1日起生效。

To improve efficiency and to avoid ethic and operational risk, Standard Chartered Bank (China) Limited (“SCB”) will make a few changes to current loan drawdown, loan rollover, repayment and prepayment instruction (“Loan Instructions”) submission process. The new process takes effect from 1st January 2015.

未同银行签订传真授权协议并有紧急提交贷款指令要求的企业及金融机构客户，在联络贵公司在本行的客户经理阐明紧急需求后，可以将指令原件以及支持性文件当面递交至或者邮寄（快递）至就近的渣打银行办理公司业务的分支行柜台（上海地区除外），选择邮寄（快递）方式时，请在地址上注明收件人为分支行营运部。

For corporate and institutional clients who have urgent drawdown requests, but are yet to sign fax instruction indemnity with SCB, they may submit the original loan instructions and supporting documents to SCB local branches (except SCB Shanghai branches) with WB service counter. Please mark the submission with attention to WB Operations.
