For instance, Austrian and Italian banks are heavily exposed in Eastern Europe; the Royal Bank of Scotland which is now majority owned by the British government does the bulk of its business abroad while a significant portion of UK housing is financed by foreign banks. Eventually the various national authorities will have to protect each other, but it is only a common danger that will force them to do so.&nbsp;
当国家的监管者试图保护他们自己的银行时，他们可能会伤害其他国家的银行系统。比如，奥地利和意大利的银行在东欧涉足颇深；现在由英国政府控股的苏格兰皇家银行的主要业务是在海外，另一方面，英国相当大一部分的住房的资金来自于外国银行。最终各国的主管部门将不得不相互保护，但是只能当面临共同的危险时才会迫使它们这么做。
