Banks offered to buy RON897.5 million worth of paper, and the maximum accepted yield was 1.24%, the data showed.
At the previous similar auction in March, the ministry sold three-month paper worth of RON500 million at a record low yield of 1.2%.
The finance ministry had planned to raise RON2.8 billion at treasury auctions in June, up from RON2.1 billion in the previous month, but volatility in the bond markets made it reject offers at an auction last Monday and scrap another tender planned for the this week.
So far in 2015, the ministry raised around RON17.6 billion at government paper auctions on local market.
