DBS Bank , OCBC and United Overseas Bank remain Southeast Asia's strongest and most valuable banking brands, a new global survey has found.

In the annual Banking 500 ranking released last week, DBS was the highest ranked in Asean at No. 48, with a brand value of US$5.31 billion (S$7.5 billion).

The value was calculated by estimating a brand's future revenue and royalty rate, based on Jan 1 data.

OCBC came second in Asean and 67th globally, with a brand value of US$3.29 billion, followed by UOB in third place regionally and 79th globally with a brand value of US$2.76 billion, the survey conducted by Brand Finance also showed.

DBS marketing and communications head Karen Ngui said: "Over the years, we have been committed to shaping the future of banking, embracing digital and embedding ourselves in the customer journey. Being recognised as one of the world's top 50 banking brands spurs us on to making banking simple, smart and effortless."
