Malaysian equities edged higher after better-than-expected economic growth data.
Singapore's Straits Times Index dropped 0.4% to 3,402.86. OCBC shed 2.5% and UOB fell 2.2%.
Earlier in the day, OCBC reported a better-than-expected 31% increase in net profit for the December quarter. UOB, the smallest of the three lenders on the STI, reported a 16% increase for the same period, slightly below expectations of analysts polled by Reuters. Both the banks continued to be cautious on their exposure to oil and gas companies, saying they made further allowances for their exposure to the sector.
DBS Group Holdings continued its outperformance following last week's proposed increase in dividend payout. The city-state's biggest lender rose 1.5%.
Singapore Airlines was the day's top performer on the STI, rising 5% after its third-quarter net profit increased by about 62% on year.
"Singapore Airlines should benefit from strong travel demand, thanks to the synchronized global economic recovery," DBS Equity Research said in a note. "With full-year earnings poised to more than double, we see room for the airline to raise its dividend payout to 40 Singapore cents from 20 Singapore cents a year ago, which implies a dividend yield of 3.8%."
ComfortDelGro Corp. edged higher by 0.5% after falling earlier in the day. The transport operator reported a 4.9% decline in net profit for 2017, weighed by weak contributions from all core businesses except the public transport segment.
Ground handler SATS lost 1% after third quarter group net profit rose 2.3%.

Over in U.S., markets continued to recover with the S&P 500 Index rising for the third day. The U.S. January consumer price index data is due for release later Wednesday and will be closely watched in the wake of recent volatility in long-term Treasury yields.
In Malaysia, the FBM KLCI closed 0.1% higher at 1,834.93. Earlier in the day, data showed that the third-largest Southeast Asian economy grew 5.9% between October and December, faster than the median estimate of 5.55% predicted in a Nikkei Markets survey of economists. Growth in the fourth quarter was powered by domestic demand and private consumption.
Genting and Genting Malaysia, considered a proxy for global fund inflows by virtue of their large foreign shareholding, rose 0.7% and 1.5%, respectively.
