The Full Form of DSIB is Domestic Systemically Important Banks.

SBI, ICICI Bank, and HDFC Bank continue to be identified as Domestic Systemically Important Banks (D-SIBs), under the same bucketing structure as last year. The additional Common Equity Tier 1 (CET1) requirement for D-SIBs has already been phased-in from April 1, 2016 and will become fully effective from April 1, 2019. The additional CET1 requirement will be in addition to the capital conservation buffer.

The Reserve Bank had issued the Framework for dealing with Domestic Systemically Important Banks (D-SIBs) on July 22, 2014. The D-SIB framework requires the Reserve Bank to disclose the names of banks designated as D-SIBs starting from 2015 and place these banks in appropriate buckets depending upon their Systemic Importance Scores (SISs). Based on the bucket in which a D-SIB is placed, an additional common equity requirement has to be applied to it. In case a foreign bank having branch presence in India is a Global Systemically Important Bank (G-SIB), it has to maintain additional CET1 capital surcharge in India as applicable to it as a G-SIB, proportionate to its Risk Weighted Assets (RWAs) in India i.e. additional CET1 buffer prescribed by the home regulator (amount) multiplied by India RWA as per consolidated global Group books divided by Total consolidated global Group RWA.
