The Reserve Bank of India (RBI) has reaffirmed State Bank of India (SBI), HDFC Bank, and ICICI Bank as the country’s Domestic Systemically Important Banks (D-SIBs) for 2025, recognising them as institutions whose stability is crucial to the nation’s financial system.

These three banks, also part of the 2024 list, continue to hold the highest significance due to their scale, interconnectedness and overall impact on India’s economy.

What D-SIB status means

D-SIBs are banks considered “too important to fail” — institutions whose collapse could trigger widespread financial instability. As a result, they are subject to higher regulatory oversight and must maintain additional capital buffers to safeguard against shocks.

In its statement issued on 2 December, the RBI said:
“State Bank of India, HDFC Bank, and ICICI Bank continue to be identified as Domestic Systemically Important Banks under the same bucketing structure as in the 2024 list.”

These additional requirements are layered on top of the Capital Conservation Buffer, strengthening each bank’s ability to absorb losses.

Higher CET1 requirements for D-SIBs

Under the RBI’s guidelines, each D-SIB must maintain extra Common Equity Tier 1 (CET1) capital based on its systemic importance. The newly published buckets for 2025 are:

  • SBI – Bucket 4: requires an additional 0.80% CET1 capital
  • HDFC Bank – Bucket 2: requires an additional 0.40% CET1 capital
  • ICICI Bank – Bucket 1: requires an additional 0.20% CET1 capital

These enhanced capital norms, aligned with Basel III standards, will come into effect from 1 April 2027.

How D-SIB designation evolved

The RBI introduced the D-SIB framework in 2014, in line with global efforts to bolster financial stability.

  • SBI became India’s first D-SIB in 2015
  • ICICI Bank was added in 2016
  • HDFC Bank joined the list in 2017

The framework ensures that institutions of national importance maintain strong balance sheets to withstand financial stress and prevent systemic disruption.

Why these banks matter

With their vast customer bases, extensive branch networks, and deep linkages across markets, these three banks form the backbone of India’s financial ecosystem. Any stress in their operations could have a ripple effect on the broader economy, making their preservation a regulatory priority.

In times of crisis, the government and RBI are expected to intervene to maintain stability, given the potential consequences of failure.
