OCBC's quarterly profit came in ahead of the market consensus.
"Looking ahead, our overall outlook remains optimistic, given the positive macroeconomic environment and the underlying growth prospects in our key markets," OCBC CEO Samuel Tsien said in a statement.
The positive outlook comes despite concerns that government and central bank curbs on property transactions and lending are set to slow growth in mortgages as well as lending to property firms, which account for about a third of bank loans in Singapore.
Analysts have cautioned the real test will come in 2015 when an expected rise in interest rates and a higher supply of homes could dent the property market.
"We're looking at a 10 percent price correction (for property) this year, which shouldn't put much pressure on credit costs, whereas the draw-downs of previously committed mortgages are likely to continue to push loan growth in mortgage," said Macquarie analyst Matthew Smith.
"That might be a very different story in 2015 though. Demand and supply looks tough, rates rising and inability to refinance could push the (housing) market down further."

DBS is in advanced talks to buy Societe Generale's Asian private bank, a deal that would help boost its private banking assets by almost a third, sources have told Reuters.
OCBC said on Friday substantial shareholders of Wing Hang Bank will have until March 3 "to seek to finalise the terms of the possible general offer by OCBC Bank."
Hong Kong banks are also seeing a slow down in mortgage growth and loans for property investment, but credit quality remains strong, analysts said. Rating agencies like Moody'shave applauded the move by Hong Kong's regulator to temper growth in personal loans as credit positive for banks because they are likely to exercise more prudence in loan underwriting.
