With the bank's stock price languishing, reaction to the rights issue is likely to have been tepid.
The latest rights issue from RBS closed yesterday, with most analysts now expecting the government to take a majority stake in the bank.
Around £15 billion of stock in the bank was on offer in the new share sale, which stems from the government's announcement of its recapitalisation plan to stabilise the UK's banking system last month. Around £20 billion of public money is on offer to the bank, which will be given through the purchase of equity stakes.
Under the terms of the recapitalisation deal, the government will purchase all the shares left over from the rights issue launched by RBS. However, yesterday the bank's shares were trading at 55p on the London Stock Exchange, while the offer price of the new sale stands at 65p per share.
This means that it is very unlikely that many people will have bought up the offered shares and the government is likely to take a stake in the bank approaching 60 percent.
RBS is one of the banks worst-hit by the credit crunch and signed up to the government's plan due to its severe need of fresh funding. In June, it launched a £12 billion rights issue - in which 95 percent of the new stock was sold - in order to try to remedy its balance sheet woes.
At a shareholders' meeting last week, RBS chairman Sir Tom McKillop said that he was "profoundly sorry" for the bank's recent performance, which has decimated the value of its stock. Sir Fred Goodwin, chief executive at the time of the onset of the crisis, stepped down last month.
