Royal Bank of Scotland is keeping quiet on speculation it is planning a share issue to prevent the British government's stake in the bank rising.
It has been reported that the bank is considering the move to repay almost £20 billion it owes for taking part in the government's toxic debt insurance scheme.
If the bank can raise the funds privately, it would stop the government's stake rising from 70% to 84%.
RBS shares have been recovering this year, trading at 56 pence compared with a low of 10 pence in January.
