There is one official global list of systemically important banks (G-SIBs). In addition, there are various national lists of systemically important banks, referred to by regulators as domestic systemically important banks (D-SIBs) - also known in Europe as national SIFIs. Special lists of regional systemically important banks (R-SIBs) also exist, but are more rare, in particular at the regulatory context.
As a regulatory response to the revealed vulnerability of the banking sector in the financial crisis of 2007–08, and attempting to come up with a solution to solve the "too big to fail" interdependence between G-SIBs and the economy of sovereign states, the Financial Stability Board (FSB) started to develop a method to identify G-SIBs (to whom a set of stricter requirements would apply) in 2009. The first publication of some leaked unofficial G-SIB lists, during a time when the FSB identification method was still being tested and subject for subsequent adjustments, took place in November 2009 and November 2010. The first official version of the G-SIB list was published by FSB in November 2011, and has ever since been updated each year in November. This G-SIB list is the first one shown below.
All G-SIBs and D-SIBs with headquarters in USA and Europe, are required each year to submit an updated emergency Resolution Plan to their Financial Supervision Authority.Basel III also requires that all identified G-SIBs no later than March 2018, shall operate with a minimum total capital adequacy ratio comprising:
This requirement towards G-SIBs depend on an indicator-based measure of size, interconnectedness, complexity, non-substitutibility and global reach, elevating it to be 1.0% or 1.5% or 2.0% or 2.5% or 3.5% higher, compared to the similar Basel III capital requirement at 7% towards banks not contained on the list.
In addition to the Basel III Capital Adequacy Ratio requirements, on November 10, 2014 the FSB issued a consultative document that defines a global standard for minimum amounts of Total Loss Absorbency Capacity ("TLAC") to be held by G-SIBs. The TLAC are amounts to be held in addition to the Capital Adequacy Ration requirements, by G-SIBs. This proposal was under consultation until February 2, 2015, when the requirement was finalized. The FSB issued the final minimum total loss-absorbing capacity (TLAC) standard for 30 G-SIBs 9 November 2015.
The second list, further below, include all those financial institutions having been identified as systemically important by a national regulator, the so-called D-SIBs. For the United States, this list include all those financial institutions not being big enough for G-SIB status, but still with high enough domestic systemically importance making them subject to the most stringent annual Stress Test (USA-ST) by the Federal Reserve.
