Adds details on bond issuance from paragraph 2 onwards

March 14 (Reuters) - DBS Group DBSM.SI, Southeast Asia's biggest bank, has raised $2 billion through a multi-tranche U.S. dollar senior bond issuance for general business purposes and to finance treasury activities, according to a term sheet seen by Reuters on Friday.

The issuance consists of two floating rate notes, raising $1 billion and $500 million with three-year and five-year tenors, respectively, along with a three-year fixed-rate note raising $500 million, offering a coupon rate of 4.403%.

Orders for both floating rate notes hit $3 billion each, with the five-year tranche receiving the most demand from 179 accounts. Meanwhile, the three-year fixed-rate note garnered $1.4 billion in interest from 102 accounts, according to the term sheet.

Asian investors accounted for nearly half of the offers, with interest from the region reaching 63% on the five-year floating rate tranche, primarily driven by asset and fund managers, as well as banks.

"The positive momentum of the order book, which was more than three times oversubscribed, is an endorsement by investors of DBS' robust and resilient franchise," said Philip Fernandez, group corporate treasurer at DBS.

The notes were issued under DBS's $30 billion global medium-term note programme.

DBS plans to use the proceeds for general purposes, as well as for finance and treasury activities, including providing intercompany loans and other forms of financing to DBS Bank Group, the term sheet showed.

DBS Bank was the sole global coordinator, joint book-runner, and lead manager, alongside BNP Paribas, Bank of America, RBC Capital Markets, HSBC, and others.
