OCBC's lower-than-expected fall in net profit came after larger peer DBS Group also posted a profit decline on weak margins but flagged a pick-up in growth.

"While economic conditions have started to show signs of stabilisation and we are seeing increased activities in some pockets of the economy, the recovery is not yet broad-based," said OCBC's Group CEO Samuel Tsien, who will be succeeded by deputy president Helen Wong in mid-April.

Analysts expect Singapore banks to show a profit rebound this year led by sustained growth in their wealth-management business and as improved economic prospects cushion the impact of net interest margins hovering near record lows.

OCBC's October-December net profit came in at S$1.13 billion ($856.1 million) versus S$1.24 billion a year earlier, and compared with the S$955.9 million average estimate of four analysts, according to data from Refinitiv.

The bank's net interest margin, a key gauge of profitability, dipped to 1.56% from 1.77% a year earlier. Full-year net profit at OCBC, which counts Singapore, Greater China and Malaysia, among its key markets, shrunk 26% from a record.

OCBC's provisions for credit losses rose 37% in the fourth quarter from a year earlier but declined from the third quarter.
