The three-year Eurobond was launched on January 22 and carries a coupon of 3.25%.
The ministry raised EUR502.5 million at the original auction in January, and another EUR581.4 million in the first reopening sale on April 4, at a record low average yield of 2.9% a year.
Apart from the EUR150 million Eurobond, the ministry plans to sell leu-denominated treasuries worth 1.76 billion lei (EUR395 million) in July, down from RON2.15 billion in the previous month.
So far in 2013, Romania sold RON26.81 billion in leu-denominated notes and EUR1.08 billion at the two euro-denominated auctions on the local market. The ministry also tapped international markets for $1.5 billion at a US dollar-bond auction in February.
