The rating action comes amid the challenges the bank faces in its operating environment, Fitch Ratings said in a statement.
"Fitch Ratings has downgraded ICICI Bank Limited's Long-Term Issuer Default Rating (IDR) to 'BB+' from 'BBB-' and its Viability Rating to 'bb+' from 'bbb-'. The Outlook on the IDR is Stable," it said.
It has also affirmed ICICI's Support Rating at '3' and Support Rating Floor at 'BB+', it said.

Fitch lowered its midpoint for India's operating environment to 'bb+' from 'bbb-' following a review of the banking sector's performance, particularly in the last three years, and its regulatory framework, as well as the outlook in the near term.
"We also compared India with other sovereign jurisdictions in Asia rated in the 'BBB' category including the key metrics of GDP per capita and the ease-of-doing-business ranking," it said.

The performance of Indian banks should have largely bottomed out, but the sector is still struggling with poor asset quality and weak core capitalisation, it said.
