It is instructive to note that almost all major multinational banks such as Citigroup, HSBC, BNP Paribas, UBS, Credit Agricole, Standard Chartered, etc. are offering these services. Why are these services spreading so fast? I can think of several possible reasons. First, there are around 15 million Muslims residing in non-Islamic countries in Europe, mostly in France, Germany and the UK.
The same principle applies to the European institutions, but implementation here is based on what is known as the MREL standard, which differs in some respects from the TLAC requirement. One difference is that all institutions will be required to satisfy the MREL requirements, not just the systemically important ones.
