The Portuguese Treasury and Debt Management Agency (IGCP) page at Bloomberg said €1.25 billion in 12-month debt was auctioned for an average of -0.345 percent, lower again than the -0.259 percent at the last similar auction in mid-July.
Portugal also sold €500 million in six-month T-bills at a yield of -0.363 percent, also better than at the July auction when the rate was -0.292 percent.
Banco Carregosa asset management director, Filipe Silva, told Lusa that in this auction, the country managed to secure the lowest rates ever for these maturities, which he said was expected after the rating upgrade of Portuguese sovereign debt by Standard & Poors last Friday and a stable outlook by Moody’s.
