Too-big-to-fail banks enjoy lower interest rates on debt than their mid-size counterparts, because lenders know that the bonds or trading contracts that such banks issue will be paid, even if the bank itself fails. Before, during, and just after the 2007-2008 financial crisis, this provided an advantage equivalent to more than one-third of the largest US banks’ equity value.
太大而不能倒的银行享受着比中等规模银行更低的债务利率，因为贷款人相信这些银行的债券和交易合同能够获得偿付，哪怕银行本身倒闭。在2007—2008年金融危机之前、之中和刚刚结束阶段，这所带来的优势相当于美国大银行股本价值的三分之一强。
