After the global financial crisis, regulators hugely increased the stringency of rules governing bank balance sheets.

全球金融危机之后，监管机构大幅提高了管理银行资产负债表的规则的严格性。

It could be that regulators didn't think hard enough about the threat posed by the large amount of securities building up on bank balance sheets.

可能是监管机构没有认真考虑银行资产负债表上积累的大量证券所构成的威胁。

But it also means that if things were to go wrong with bank balance sheets, you know, we're ultimately dealing with very large state-owned enterprises here rather than private sector companies.

但这也意味着， 如果银行资产负债表出现问题，我们最终会与非常大的国有企业而不是私营部门公司打交道。
