The first banks to receive money under the UK government's bank rescue scheme could do so as soon as Monday morning, BBC reported.
The banks and the Treasury are working on announcements to be made before the markets open, according to BBC business editor Robert Peston.
He says the first banks to take up the recapitalisation are likely to be HBOS and Royal Bank of Scotland (RBS).
A key aspect of the announcements will be what the government requires the banks to do in return for the cash.
The government is not expected to insist on having its own appointees on the boards of the banks, although other strings are likely to be attached.
These could involve curbing executive pay and resuming normal lending to individuals and small businesses.
