SINGAPORE (Reuters) -Singapore's second biggest lender Oversea-Chinese Banking Corp (OCBC) on Wednesday reported a 39% jump in its first-quarter net profit from a year earlier on the back of strong net interest income growth.

OCBC, which is also Southeast Asia's second biggest bank by assets, said January-March net profit jumped to a record S$1.88 billion ($1.42 billion) from S$1.36 billion a year earlier. That beat the mean estimate of S$1.74 billion from five analysts surveyed by Refinitiv.
