Lloyds, which is 41 per cent owned by the government after being bailed out during the 2008 credit crisis, said it made a nine-month loss of £3.86bn after its earnings were hit by lower banking margins and higher funding costs.
The bank had made a first-half loss of £3.25bn, hit by compensation for customers mis-sold insurance products.
Lloyds shocked investors last week by announcing 47-year-old Chief Executive Antonio Horta-Osorio was taking a break due to stress-related illness, leaving a potential power vacuum at the top of Britain's biggest retail bank.
It gave no update on his health in its latest statement.
Lloyds said it had begun talks with the UK Listing Authority over the possible spin-off and listing of 632 retail bank branches it has been ordered to sell.
It plans to sell the branches and new bank venture NBNK and Co-Op Financial Services have said they will bid, but could list them if offers are too low.
"We are aiming to identify a preferred option by the year end," it said.
Tim Tookey, the finance director who is due to leave the bank in February, is serving as interim CEO, adding to worries that a major executive shake-up by Horta-Osorio has left Lloyds thin at the top at a time when it faces several headwinds.
