IDFC First Bank has received a reaffirmation of its credit rating from ICRA, one of India's leading rating agencies. ICRA has maintained its AA+/Stable rating on ₹12,520 crore of the bank's bonds, underscoring the institution's strong creditworthiness. In a separate action, the agency has also withdrawn ratings on ₹3,883.70 crore of non-convertible debentures (NCDs) following their full repayment, with no outstanding dues remaining on these instruments.

Rating Actions at a Glance

The two distinct rating actions cover a significant quantum of debt instruments. The table below summarises the key details of ICRA's latest rating decisions:

Reaffirmation of AA+/Stable Rating

The reaffirmation of the AA+/Stable rating on ₹12,520 crore of IDFC First Bank's bonds signals ICRA's continued assessment of the bank's credit quality at a high level. An AA+ rating denotes a very high degree of safety regarding timely servicing of financial obligations, with the Stable outlook indicating no immediate expectation of a rating change.

Withdrawal of NCD Ratings

ICRA has simultaneously withdrawn its ratings on ₹3,883.70 crore of NCDs issued by IDFC First Bank. The withdrawal follows the complete repayment of these instruments, with the rating agency confirming that no outstanding dues remain. Such withdrawals are a standard regulatory and procedural action once debt obligations are fully settled, reflecting the closure of those specific issuances.

Key Highlights

• AA+/Stable rating reaffirmed on ₹12,520 crore of bonds
• Ratings withdrawn on ₹3,883.70 crore of NCDs post full repayment
• No outstanding dues remain on the withdrawn NCD instruments
• Rating withdrawal is consistent with standard practice upon debt repayment

The dual rating actions by ICRA reflect both the ongoing strength of IDFC First Bank's credit profile on its active bond issuances and the orderly retirement of its previously rated NCD obligations.
