Standard Chartered, which is based in London but makes almost all its money in Asia, the Middle East and Africa - regions where Liverpool has a strong following - has been the club's shirt sponsor since July 2010.
The original deal was worth about 20 million pounds ($30 million) a season. Financial details of the extension were not released, but a person familiar with the matter said the terms were broadly similar, with potential top-ups if the club is successful. The deal will run until at least the end of the 2015/16 season.
