Petrobras has tapped the international bond markets to raise $6.75bn in the first such sale by any Brazilian company since June.

The Brazilian oil major sold $5bn in five-year notes at a coupon of 8.625% and $1.75bn in 10-year notes at a 9% yield.

Proceeds from the sale of the senior unsecured notes will be used to fund a buy back up to $6bn of debt maturing in 2018

The issue attracted demand from investors of around $20bn, according to a banker, who was involved in the transaction.
