SINGAPORE, Aug 4 (Reuters) - Singapore's DBS Group posted a better-than-expected 7% rise in quarterly net profit on Thursday as Southeast Asia's largest lender benefited from rising interest rates.

The bank reported net profit for April-June increased to S$1.8 billion ($1.30 billion) from S$1.7 billion a year earlier, compared with an average estimate of S$1.69 billion from five analysts compiled by Refinitiv data.
