FITCH Ratings on Tuesday affirmed Singapore Telecommunications' (Singtel) long-term foreign and local-currency issuer default ratings as well as its senior unsecured rating at "A+".
The credit rating agency also affirmed Singtel's wholly owned subsidiary (its Australian unit) Optus' long-term foreign-currency issuer default ratings and senior unsecured rating at "A".
The outlook on both issuer default ratings is "stable", Fitch said in a media statement.
Singtel's rating has "limited potential" to rise in the short to medium term, the agency added.
