Moody's revised its outlook on Hong Kong's credit ratings to stable from negative on the city's resilience amid global trade tensions and lower trade growth, according to a Tuesday note by the debt watcher.

The city's policy framework is seen to preserve its creditworthiness despite downward pressures on mainland China's ratings, Moody's said.

Moody's also affirmed the Aa3 local and foreign-currency long-term issuer ratings, foreign-currency senior unsecured ratings, and its (P)Aa3 local and foreign-currency senior unsecured medium-term note program ratings.

Meanwhile, S&P also affirmed Hong Kong's AA+/A-1+ long- and short-term issuer credit ratings, attributable to policymaking that has allowed for a high per-capita income, strong fiscal buffers and external balance sheets, and trustworthy monetary institutions.

The outlook on S&P's ratings remains stable, in line with other high-income economies, despite uncertain economic conditions, for at least the next two years.
