BRASILIA, Jan 22 (Reuters) - Brazil raised $4.5 billion on Monday in its first entry this year into the global dollar-denominated debt market, with the sale of 10-year and 30-year bonds, according to a source with knowledge of the deal.

The Treasury said the bonds were aimed at boosting liquidity and providing a guidepost for corporate borrowing, and that results would be disclosed later on in the day. It did not immediately respond to a request for comment.

According to the source, who spoke on anonymity as details of the deals are not yet public, Brazil raised $2.25 billion with each of the bond sales.

The 10-year bonds featured a 6.35% yield, with a 7.15% yield for the 30-year bonds, the source said.

Demand for the 10-year bond reached almost $7 billion, and exceeded $7 billion for the 30-year bond, the source added.

Citigroup, Scotiabank and UBS led the operation, according to the Treasury.

Brazil's latest move follows its successful raising of $2 billion in November through its inaugural "green" bond issuance, aimed at directing funds toward the government's ambitious sustainability agenda.

Before that, the country's last traditional foreign debt issue took place in April 2023, when it raised $2.25 billion in a 10-year sovereign bond offering. (Reporting by Marcela Ayres; Editing by Chizu Nomiyama and Jonathan Oatis)
