Banks offered RON1.46 billion, but the ministry rejected all yields above 5.59% a year, central bank data showed.
The previous similar auction was held on October 1, when the ministry sold RON972 million in six-month paper at an annual yield of 5.91%.
The ministry has already exceeded its issuance plans for January, of RON4.6 billion. It has raised RON10.28 billion at seven out of eight auctions scheduled this month, taking advantage of a positive sentiment in the market following the parliamentary elections in December.
Thursday, the ministry hopes to sell debt worth RON600 million at a 10-year bond auction.
Also this week, the institution plans to raise EUR150 million at a euro-denominated bond sale on the local market to finance the budget deficit. (EUR1=RON4.3481)
