The federal government has raised another $1 billion with its third issue of 50-year bonds so far this year.

The latest issuance of ultra-long bonds brings the total raised this year through these new debt instruments to $3.5 billion.

The government said Thursday that the additional issuance of bonds in the ultra-long sector is in line with its commitment “to reallocate short-term bond issuance towards long-term bonds to help reduce refinancing risk and to lock in low funding costs for Canadian taxpayers.”

The ultra-long bonds issued by the government mature on December 1, 2064, and carry a yield of 2.575%. Once again, it reports that it received “exceptionally strong demand” for the issue from both domestic and international investors, with 36 individual accounts participating in the deal.

This is the second time that an issue that was originally launched in April has been reopened by the government. “I am pleased to announce another successful reopening of Canada’s 50-year long-term bond,” said federal Finance minister, Joe Oliver. “With this transaction, the government continues to deliver on its commitment to secure low-cost funding for Canadians. We have also seen growing diversity in our investor base, which is a testament to Canada’s strong economic and fiscal position and to the flexibility and options associated with Canada’s debt securities program.”
