BUCHAREST, Oct 26 (Reuters) - Romania's finance ministry rejected all bids at a tender to sell one-year treasury bills, central bank data showed, due to unacceptably high yield levels.
The finance ministry had planned to sell 1 billion lei.
At a previous tender to sell one-year bills on Oct. 19, the average accepted yield was set from 10 percent.
In recent months, it has scaled back issuance or rejected all bids at several tenders, signalling yields were too high.
Analysts warn the ministry could face strong upward yield pressure after the government collapse earlier this month, which has raised concerns over the country's ability to enforce reforms under its International Monetary Fund aid package.
But its funding needs could soar towards the end of the year, when spending jumps tend to occur, particularly as the ministry has postponed a planned Eurobond issue, initially seen in October, due to political uncertainty.
So far this year, Romania has sold a little under 58 billion lei in local debt issues, five times more than in 2008
