KUALA LUMPUR: Malaysia's national oil company Petroliam Nasional Berhad, or Petronas, said on Friday it had raised $3 billion from a bond offering to refinance debt and for other corporate purposes.

The issuance was 2.46 times the initial offer size, and a 40-year bond tranche was the largest ever by a Southeast Asian issuer, the company said in a statement.

"Supported by strong investor demand, Petronas was able to upsize the transaction size to $3 billion based on total demand of $7.4 billion," it said.

The offering included $1.25 billion of 10.75-year and $1.75 billion of 40-year conventional notes.

The 10.75-year senior notes were priced at 92.5 basis points (bps) over the 10-year U.S. Treasury yield for a coupon of 2.48%, and the 40-year senior notes were priced 115 bps over the 30-year US Treasury for a coupon of 3.404%.

Last month, Petronas' subsidiary Petronas Energy Canada Ltd raised $600 million from another bond offering to fund production and refinance debt.

Petronas has taken a hit from the coronavirus pandemic which has reduced fuel demand. Earlier this year, the state-owned company posted its third quarterly loss in a row and warned that the outlook remained challenging
