Dear Sir,

Re: Press Release.

HDFC Bank has outstanding bonds totaling to approx USD 1.20 bn issued from the Bahrain branch. These bonds have a dual rating from Standard & Poor’s (S&P) of BBB- and Moody’s of Baa3. In February 2016, consequent to a downgrade in the rating of Bahrain, S&P put the Bonds issued by HDFC Bank, Bahrain branch on CreditWatch with Negative implications. The issuer rating however remained unaffected at BBB-.

Subsequently, the Bank has modified the existing structure of the bonds. Under the revised structure, if any event materializes thereby restraining the Bank’s ability to service the bonds from Bahrain branch, the Bank will service the bonds from any branch in India or from the Hong Kong branch. Consequent to these modifications, on 19th July 2016, S&P issued a release removing the CreditWatch and re-affirming the long-term issue ratings on the senior unsecured bonds issued by the Bahrain branch of HDFC Bank Ltd at BBB-

This is for your information and record.

Thanking you,

Yours faithfully,

For HDFC Bank Limited

SINGAPORE (S&P Global Ratings) July 19, 2016—S&P Global Ratings today affirmed its ‘BBB-’ long-term issue ratings on the senior unsecured bonds issued by the Bahrain branch of HDFC Bank Ltd. (BBB-/Stable/A-3). We removed the ratings from CreditWatch, where they were placed with negative implications on Feb. 22, 2016.

At the same time, we raised the Greater China regional scale rating on HDFC Bank’s Chinese yuan (CNY) 150 million 4.30% bond maturing 2018 to ‘cnA-’ from ‘cnBBB+’, and removed it from CreditWatch, where it was placed with developing implications on Feb. 22, 2016. The ‘cnA-’ Greater China regional scale rating on the CNY bonds is in line with S&P Global Ratings’ “National And Regional Scale Mapping Tables,” published June 1, 2016, on RatingsDirect.

Our rating actions follow HDFC Bank’s announcement that it has put in place a structure such that, if an event materializes to prevent the bank’s Bahrain branch from making payments under the notes, HDFC Bank’s Hong Kong branch or a branch in India is obligated to make full and timely payment under these notes. We understand that HDFC Bank has already obtained specific approval from the Reserve Bank of India to make the payment for debt obligations arising on these bonds. With regard to the Hong Kong branch, we are not aware of any regulation that will specifically prohibit the bank from making payment to these bondholders.

As such, we do not consider the ratings on these bonds to be constrained by the rating on the host country (Bahrain). We rate such bonds issued by the Bahrain branch at the same level as the rating on HDFC Bank. Our “Assessing Bank Branch Creditworthiness” criteria published Oct. 14, 2013, enables us to consider these branches as effective obligors in situations when the Bahrain branch is unable to make payments under the notes.
