The Royal Bank of Scotland (RBS) has confirmed it is thinking about a rights issue but has not given away any further details.
The company "is considering a rights issue" and will give details "in due course," the Edinburgh-based bank said in a brief statement to the stock exchange.
According to a report in the Sunday Times over the weekend, the bank will announce write-downs of between £5 billion and £7 billion this week.
The report also said RBS intends to raise between £10 billion and £12 billion through a widely-anticipated rights issue and sell off assets worth as much as £5 billion.
In addition, The Times newspaper said on Monday that RBS would announce the sale of train leasing company Angel Trains for £3.5 billion.
The report also said RBS is expected to say that it is conducting a 'strategic review' of insurance brands Direct Line and Churchill, signaling it is open to offers.
Britain's second largest bank is believed to have depleted reserves due to subprime-related losses and last year's takeover of Dutch group ABN Amro for 71 billion.
Shares in RBS rose 2.8 per cent to 395p in early trading.
