Likewise, the European Union, in contrast to the United States, regards the leverage ratio as a supervisory optional extra, known as a “Pillar 2 measure” (which permits supervisors to add additional capital buffers to address a particular bank’s idiosyncratic risks). And, though both the US and the EU prohibit proprietary trading, they each define it differently.
类似地，与美国不同，欧盟把杠杆率作为可选监管项，称之为“支柱2手段”（Pillar 2 measure，它允许监管者增加资本缓冲以解决特定银行的特别风险）。此外，尽管美国和欧盟都禁止了自营交易，但对该业务的定义有所不同。
