(Adds context on the property market, S&P comments in paragraphs 7-10) By Iain Withers LONDON, Dec 4 (Reuters) - Sluggish global growth, a higher risk of borrowers defaulting on loans and pressure on profitability mean that banks face a negative outlook in 2024, credit rating agency Moody's said on Monday. Prior rate hikes by central banks and rising unemployment in advanced economies will weaken asset quality, Moody's Investors Services said in an outlook report, adding that real estate exposures in the United States and Europe posed a growing risk. Pockets of stress in property markets in the Asia-Pacific region were also likely to continue, the report said. Global banks have reported mixed performances this year, as their consumer revenues have benefited from higher rates set by central banks to curb inflation, at the same time as investment banking revenues have been dented by a deep dealmaking slump.
