SINGAPORE'S three largest banks by assets - DBS, OCBC, and UOB - will face rising asset risk and slowing income growth in 2019 as economic conditions worsen, despite posting record results for the first half-year, Moody's Investors Service said in a report released on Tuesday. Simon Chen, Moody's vice-president and senior analyst, said: "DBS, OCBC and UOB posted record net profits, stable asset quality and strong capital for H1 2019, but further improvement in profitability will be difficult amid slowing global growth, and the potential for an escalation of the US-China trade conflict. "Specifically, we expect income growth to slow because net interest margins will either stagnate or decline, as central banks globally cut rates, while credit costs will rise and loan growth will moderate due to the increasingly uncertain environment."
