Explanation:

The Reserve Bank of India (RBI) has announced that SBI, ICICI and HDFC Banks would continue as Domestic Systemically Important Banks (D-SIBs) for 2018.

The recognition as Domestic Systemically Important Banks (D-SIBs) implies that banks are too big to fail. This creates an expectation of government support for them in times of financial distress. As a result, banks enjoy certain advantages in funding markets. Inclusion in the list gives additional comfort to investors that these banks won’t be allowed to fail and therefore, borrowing costs of these banks from the markets are cheaper than their peers.
